Evolution of Car Manufacturers



Manufacturers Popularity and Decline

There were over 300 companies building electric cars at the turn of the 20th century. At that time the United States had over 30,000 electric cars on the road. The Electric Vehicle Association of America (EVAA) was founded by Boston Edison in 1909. Electric cars were clean and quiet, and did not require manual starting by physically cranking the motor by hand. The biggest demographic customer base for these cars was women. Even Henry Ford's wife drove an electric car.

In 1913 Cadillac invented the electric starter; this was a huge advance, truly a milestone in automotive technology for internal combustion cars.  The internal combustion assembly lines of Henry Ford, active since 1908, caused a further decline in the use of electric cars. Ford's assembly line made cars inexpensive and it helped make them more uniform.  Parts were not custom made for each vehicle, this made repairs and replacements easier and more economic. At the time, electrics were still popular for some non-road applications, such as service vehicles like carts and forklifts.

Infrastructure

With more cars of all types being produced the transportation infrastructure began to improve dramatically. We began building more paved roads. This also made internal combustion cars more desirable because of their greater range. Even Thomas Edison preferred gasoline to electric. As gasoline vehicles became more popular we began building more service and support for them.  Garages and gas stations began to appear in more locations, making it easier to own and operate a gas vehicle.

Today's Hybrids and Electrics

Hybrid vehicles became popular at the turn of the 21st century. Fuel prices reached record levels, quickly going from two dollars to three dollars, and eventually to over four dollars per gallon. One of the first vehicles to reach critical success in the consumer marketplace was the hybrid Toyota Prius. This vehicle is affordable, efficient and advanced, its hybrid technology blurring the lines between the performance of electric and internal combustion vehicles.  Hybrids' have two drive trains that work with each other to provide the work to drive the vehicle.  Development of the Hybrid has produced new technology which combines the drive trains at a price people are willing to pay.  A side benefit of their development has been to show that electric technology works effectively.  Some Hybrid owners have done conversions allowing for their vehicles to be charged by directly plugging in, these are known as plug-in-hybrid-electric-vehicles (PHEV).

The history of electric cars and trucks is filled with both facts and politics. Arguably, the best electric vehicles (EVs) are the one produced by the major auto manufacturers.  The major manufacturers produced both "ground-up", or original EVs, and conversions of existing vehicles.  Most of these vehicles are no longer in existence due to the auto makers' claims that there is not enough consumer demand.  Economics have come into question at various times, as the major vehicle makers have a vested stake in their existing internal combustion engine (ICE) technology.

  Smaller manufacturers have attempted to build electric cars and trucks with varying degrees of success.  Some of the vehicles produced by these companies look similar to the internal combustion cars and trucks we drive, and others appear much more exotic.  Size is important in order to maximize range, so some vehicles are extremely light, almost like bicycles.  Others have been built with three wheels to qualify for motor vehicle licensing in the motorcycle category.  Cars have been produced with direct drive motors, chain drive, belt drive, hub motors.  

Several smaller "boutique", or specialty manufacturers still convert vehicles today. The degree of their quality and performance varies dramatically.  Some companies offer parts that are kitted into standardized assemblies, others simply provide general instructions and ideas, often with a loose recipe of parts and where to find them.

Many hobbyists are drawn to conversions because of the design and creativity necessary to convert one existing design into another.  Because of this freedom, many strange and unique features have come from individual projects.  This experimentation has included charging trailers that are towed behind the with a gas generator (the first "hybrids"); regenerative braking that puts energy back into the battery pack by temporarily making the motor into a charger; even exploring with solar or motion generators attached to the EV.

  The moderate or limited success of these early inventors has both helped and hurt the EV industry.  The best outcome has been that they have proven the concept.  EVs are possible, the technology is here and can be assembled by almost anyone.  The negative side is that some of the early vehicles produced were unappealing to consumers.  The main buyers of these concept cars were early adopters who were willing to try out new technology. Many people believe that a car or truck is not really viable unless it is made by a major car manufacturer.

Your project is the combination of a "major manufacturer" and a "boutique" shop.  The S-10 was manufactured by General Motors, and the conversion kit was made by Electric Auto Shop.  Putting them together into the electric drive truck will use another boutique shop, you and your school.

 Today's Fuel Cell Vehicles

Using fuel cells in vehicles may be new technology, but fuel cells were introduced over 100 years ago.  In this technology, fuel material is converted into electricity.  The fuel material can be a stream of hydrogen gas.  Like a lead acid battery, there is action between the cathode and anode which produces work to the wheels to drive the vehicle.  One drawback is that the fuel cell vehicle is expensive and needs a lot of space for the fuel cell to complete its conversion process.

Tesla Motors




Tesla Motors files for IPO, seeking $100 million


LOS ANGELES (MarketWatch) -- High-end electric-car company Tesla Motors filed for an initial public offering Friday, seeking $100 million in the public-financing arena as conventional auto makers are reeling from anemic sales and product recalls.


Palo Alto, Calif.-based Tesla filed documents with the U.S. Securities and Exchange Commission, but did not indicate in the filing when those shares would be sold on the public markets, nor what the initial price would be. Company executives could not be immediately reached for comment.


If successful, the IPO could help usher in a new era for the auto industry, which is steadily moving toward cleaner-burning engines.


Toyota's recall debacle

Japanese auto-maker Toyota may have to recall 8 million vehicles world-wide over safety fears that some analysts blame on cost-cutting measures.

The IPO is expected to be one of the most high-profile offerings in some time, and is the first by a U.S. automaker since Ford Motor Co. (entered the public markets in 1956.)

Whether Tesla can take advantage and shift public tastes more toward zero-emission cars is unclear. But the timing of the IPO could prove to be shrewd.

"We believe incumbent automobile manufacturers are at a crossroads and face significant industry-wide challenges," Tesla said in its filing, adding that "the legacy investments made by incumbent automobile manufacturers in manufacturing and technology related to the internal combustion engine have to date inhibited rapid innovation in alternative-fuel powertrain technologies."


While Ford has been prospering of late, rivals General Motors and Chrysler have been suffering from downtrodden sales, and were taken over by the federal government last year. Meanwhile, top foreign producer Toyota Motor Corp.  is having to recall millions of its automobiles around the globe due to a problem with sticking accelerator pedals.

The Tesla Model S.

Tesla first started selling its $100,000 all-electric sports car, the Roadster, in 2008 and followed that up last year with the Roadster 2. The company claims in its IPO filing that the car has a range of 236 miles on a single charge, and says it has sold 937 of the vehicles in 18 countries.

It is designing a sedan designed for family use, the Model S, which would run for $49,900 after a $7,500 federal tax credit, the company's IPO said. The sedan would have a range of 160 to 300 miles on a single charge. In addition, Tesla is negotiating with Daimler AG  to provide its electric powertrain and battery technology for Daimler's Smart fortwo car. One thousand Tesla battery packs and chargers are being used in a trial with Smart fortwo cars in five European cities.

Tesla said it has taken out a $465 million long-term loan with the Energy Department under its advanced-vehicles manufacturing program to build a facility that will manufacture the Model S. The company added that it has been given up to $31 million under similar California state programs.

In the filing, Tesla indicated its revenue will decrease substantially before the Model S is rolled out -- expected to be sometime in 2012. That is because Tesla will cease selling its roadsters in 2011 and won't resume production on a new model until at least 2013.

The SOTU and Energy

Given the central focus of this year's State of the Union Address on the economy and jobs, I wasn't surprised to hear the President highlight "clean energy jobs"--a phrase that seems to have replaced the formerly ubiquitous "green jobs"--though I was relieved that he didn't hang the whole weight of his administration's jobs focus on them. I was even more pleased at the apparent evolution and broadening of his perspective on energy, compared to his first address to a joint session of Congress last February, when oil was only brought up in the context of its imports, and nuclear power wasn't mentioned once. By contrast, last night the President spoke of the need for expanding nuclear power and "making tough decisions about opening new offshore areas for oil and gas development." If he is serious about the latter course, he must reinforce that message with the agencies involved.

It's just as well that the green jobs refrain has become more muted, since as I've noted before, the main employment impact of energy isn't from the people who are employed producing and distributing it, as I formerly was, but from its cost and availability for the other 92% or so of the economy not engaged in some aspect of the energy business. Simply put, if we want the economy to grow at a healthy pace and create lots of new jobs, then it's more important that energy be as affordable as possible, than that we employ as many Americans as possible in the energy industry. That means we must not only increase our production of new renewable energy, which while growing rapidly contributes just 5% of our total supply, but also those sources that still account for 95% of our energy use.

If President Obama is willing to make "tough decisions" on oil and gas--presumably to open up access to them--then it is unfortunate that as he was proposing this, his Department of the Interior was engaged in a hay-throwing contest with the American Petroleum Institute over the oil & gas leasing results for 2009, which brought in $6 billion less than in 2008, just for offshore. Whatever explains this anemic performance, the record of the last year strongly suggests that this administration is a much more reluctant participant in this activity than its predecessor. Although that may please some constituencies, it hardly advances the cause of delivering more domestic energy supplies from these sources. And for Interior to cite a 14% increase in oil production last year in defense of its current practices makes me wonder how well its new management really understands the processes involved, since the time required for permitting and construction makes it extremely unlikely that the increase is attributable to leases awarded since January '09.

In order to promote the affordable energy needed for growing the economy and creating jobs, the President should also rein in efforts to entangle the most important energy development of the last decade, natural gas produced from shale and other unconventional resources, in new regulations surrounding a decades-old drilling practice that in essence involves injecting water into the subsurface, along with chemicals quite similar to those that drillers are seeking to extract from there. Promoting domestic energy will also require taking a much more pragmatic approach to climate legislation than that represented by the 1400 page monstrosity of Waxman-Markey that he praised last night, and avoiding the temptation to turn the EPA loose to regulate greenhouse gas emissions from facilities consuming the equivalent of as little as 150 barrels per day of oil, or roughly one tank truck a day.

If the President has truly begun to embrace an "all of the above" energy strategy, that would be very good news for the country. We need more energy from our abundant domestic sources--including oil, natural gas, nuclear power and renewables--to get the economy growing at a pace sufficient to generate millions of new jobs. Unfortunately, I can't help recalling that only a few months ago a top official in the Treasury Department offered Congress his view that the US was overproducing oil and gas. The onus is now on the administration to demonstrate that the energy commitments President Obama made last night will be carried through.

Toyota Electric



Toyota to Build All-Electric Car by 2012

Toyota promises to have a compact "Urban Commuter" car that runs entirely on electricity for sale by 2012. The automaker will also speed up the rollout of plug-in electric Prius models powered by lithium-ion batteries, and build a Lexus hybrid.




Toyota, the leader in hybrid car sales, plans to have a Battery Power compact car called the FT-EV on the market by 2012 – a lightweight four seat, model on its gasoline-powered IQ, that will have an all-electric range of 50 miles.

Toyota's move toward an all-electric car follows those by companies like Nissan, Mitsubishi, Think and several others aiming for the commuter market, where the shorter ranges of battery-powered vehicles are seen as less of a drawback.

As for its hybrid plans, Toyota said it will begin delivering Prius hybrids that can be plugged in to recharge their batteries in 2009, slightly earlier than a previously announced 2010 rollout date. About 500 of the plug-in hybrids will be used for market and engineering analysis by lease fleet customers.

Those plug-in Priuses will be powered by lithium-ion batteries built at a plant owned by Toyota and Panasonic EV Energy Co., the company announced. Current Prius models use nickel-metal hydride batteries.

Toyota showed off test models of the FT-EV and new versions of the hybrid third-generation Toyota Prius and Lexus HS250h at the North American International Auto Show in Detroit this weekend. Startups Tesla Motors and Fisker Automotive, as well as financially troubled automaker Chrysler, are introducing all-electric sports cars at the show.

The push for more fuel-efficient vehicles comes amid a dire economic climate, with sales of new cars plummeting and American automakers General Motors and Chrysler tapping up to $17.4 billion in federal bailout funds to avoid bankruptcy.

General Motors plans to have its plug-in hybrid Chevy Volt on sale in 2010. Ford said it plans to be building an all-electric commercial van by 2010, an all-electric passenger car by 2011, and plug-in hybrid vehicles by 2012.

The economic downturn and falling oil prices have hurt sales of hybrids along with broader auto sales. Toyota's hybrid car sales in the United States fell 53 percent in November from a year ago, and the company expects to post its first operating loss in 70 years for the fiscal year ending in March.

But Toyota's push toward electric and plug-in hybrid cars is part of the company's recognition that, despite currently falling oil and gasoline prices, "the inevitability of peak oil," or the coming peak and decline of production from the world's oil fields, will force automakers to make more fuel-efficient cars. Other automakers have also reported steeply declining sales. The poor economic climate has led seven automakers to scale down or cut their presence at the auto show, including Nissan, Mitsubishi, Rolls-Royce and Land Rover.

Best Hybrid



Test Drive: 2010 Ford Fusion is best gas-electric hybrid yet


OK, let's just get it out there: The 2010 Ford Fusion hybrid is the best gasoline-electric hybrid yet.
What makes it best is a top-drawer blend of an already very good midsize sedan with the industry's smoothest, best-integrated gas-electric power system. It's so well-done that you have to look to the $107,000 Lexus LS 600h hybrid to come close.


Fusion's $28,000 starting price is more or less in reach, the driving feel is good, and the interior has a premium look and feel.

There are three facets to consider in evaluating a gasoline-electric hybrid: the underlying vehicle itself, the hybrid system and the mileage.

Assuming the preproduction Fusion hybrid test car was representative — Ford says it was — the Fusion's scores in those three categories are good, great and adequate, but potentially, very good.

The Toyota Prius crowd will protest. Prius is lower-priced, has about the same room inside, has a handy hatchback configuration, gets better mileage — and most of those attributes could improve when the 2010 Prius goes on sale in a few months — so how could Fusion be the best hybrid?

Simple. Fusion drives better. A car is, after all, a driving machine. Brownie points for saving somewhat more fuel or offering a cargo-friendly hatchback, but driving feel is most important.

And there, Fusion is without equal among hybrids.

Here's a look:

•The car. A slick machine, regardless of power-plant. Smooth looks. Good manners. Adequate space. Comfortable accommodations. Above-average ambience.

Ford launched Fusion as a gasoline-only car in 2005 as a 2006 model.

It's getting a mid-cycle update for 2010, including a hybrid version for the first time, which will begin arriving at dealers mid-March.

The hood has a wide, demi-dome bulge, and the grille and rump are tweaked a bit.

The grille now looks as if it was done that way on purpose.

A commendable change: The turning circle is 2 feet narrower. No more back-and-forth getting into or out of a tight parking spot at the shopping mall. The change makes the car feel more nimble overall, not just when docking in a narrow slot.

•Hybrid system. The basic four-cylinder gasoline engine is a 2.5-liter, up from a 2.3-liter in previous Fusions. A little more oomph is the welcome result. The aural signature could be better — it comes down on the coarse side when spurred hard — but isn't a deal-breaker. The electric motor delivers more crank than you get from the gas engines in most small cars.

And the miracle is how Ford blends the two. There was no — none, nada, zip — vibration or shimmying in the test car when the gasoline kicked in to help the electric. No other hybrid — not even that $107,000 Lexus — can make that claim 100% of the time.

Fusion's main rivals, Camry and Nissan Altima hybrids, shake a lot when their gasoline engines join the party, Altima especially.

And no, it's not worth accepting the lack of refinement as a price for saving fuel. It'll make you bitter and crazy after a while, wincing in advance knowing that shudder is due any second.

One Ford trick: using the engine's electronic controls to halt the gasoline engine just at the point in the crankshaft rotation where a cylinder is ready to fire again.

There was a distant shudder when the Fusion's gasoline engine restarted after stopping at a red light, as all hybrids do to save fuel. But it was milder than in any other hybrid tested, so minor as to be inconsequential.

The other great thing about the Fusion hybrid is information delivery. You can pick how much hybrid-related data you want on the instrument panel. Regardless of how much you ask for, Fusion delivers it informatively, no scolding or overwhelming you, as other hybrids do.

Yes, there's the "atta way" pictograph of leaves growing into a wreath if you drive just so. But you can shut that off.

• Mileage. Mediocre for a hybrid in the test, but the mileage numbers were continuing to climb even as the test ended. And the car registered 40-plus miles per gallon in a couple of short trips that usually return crummy, not outstanding, mileage.

Best guess: Moderate, but not mileage-obsessed, drivers could get 35 mpg or so in suburban settings. Not the 41 government rating, but impressive for a 3,720-pound midsizer.

Fusion's city mileage rating is better than Camry's 33 mpg, but does it get more in real life? Probably depends more on the driver than the car.

Even if the Fusion gets lower real-world results, it's still much smoother and a whole lot nicer to drive.

More about the 2010 Ford Fusion hybrid

What? Gasoline-electric hybrid version of midsize, four-door, front-drive Fusion that's been updated for 2010 model year. Ford's Mercury brand sells the nearly identical Milan.

When? Hybrid and gasoline versions begin arriving at dealers in March.

Where? Made at Hermosillo, Mexico.

Why? Pirate some sales from Toyota's Camry hybrid. And burnish Ford's "green" credentials.

How much? Starts at $27,995 ($3,295 more than most similar gas model). With all factory options: $32,435. Midlevel test car: $29,590 (no leather or navigation system). Gasoline model starts at $19,995.

How many? About 20,000 a year, including a few Milans; more if Mikey likes it.

How powerful? Modestly — punch not being the key issue in a hybrid: 2.5-liter gasoline engine rated 156 horsepower at 6,000 rpm, 136 pounds-feet of torque at 2,250 rpm. Electric motor: 106 hp at 6,500 rpm, 166 lbs.-ft. the moment it begins to turn (an appealing attribute of electric motors). Ford says net combined hp is 191, but declines (like most hybrid makers) to specify net combined torque.

Continuously variable automatic transmission blends power from the gas, electric powerplants.

How fancy? Lots standard, including expected bags, belts, stability and traction controls and power accessories, plus the unexpected: Free six-month satellite radio service (Sirius), 110-volt outlet, six-CD stereo (instead of the typical single setup), dual-zone climate control, auto on-off headlights, auto-dimming mirror, backup alarm. In other words, you actually could abide the base Fusion hybrid.

How big? On the small end of the midsize scale. Fractionally bigger outside than Toyota Camry hybrid, slightly smaller inside, but has a bigger trunk.

Fusion hybrid is 190.6 inches long, 72.2 in. wide, 56.9 in. tall on a 107.4-in. wheelbase.

Passenger space is listed as 99.8 cubic feet, trunk as 11.8 cu. ft. Weight listed as 3,720 lbs. Turning diameter is 37.5 ft.

How thirsty? Rated 41 miles per gallon in town, 36 on the highway, 39 in combined driving.

Test car trip computer showed 27.2 mpg (but was continuing to climb when test period ended) in 300 miles of suburban driving. Registered a remarkable 41.4 mpg in one 5.1-mile suburban trip, 44 mpg in a 3.1-mile hop, driven normally, no nursing.

Tank holds 17 gallons. Regular (87 octane) gasoline is specified.

Overall:  Best hybrid.

910 Miles Per Gallon*

Yesterday provided one of those occasional treats that makes blogging about energy so enjoyable. In conjunction with the Washington Auto Show, I had the opportunity to drive a demonstration version of the eagerly-awaited Chevrolet Volt around an impromptu test track, accompanied by the Volt's Vehicle Line Director, Tony Posawatz, who answered every question that occurred to me and many that didn't. The experience was exhilarating. For a bona fide car of the future the Volt--even in "pre-production" form--looked and handled like a real car that I could imagine myself driving around town or on a long trip, aside from its impressive technology and efficiency. That's an important distinction, since to be truly successful the Volt and its eventual siblings must be able to compete beyond a niche market of green-oriented consumers.


My test-drive of the Volt was the latest in a series of advanced vehicle experiences that includes driving a Fuel Cell Equinox a couple of years ago and goes back to a spin around Phoenix behind the wheel of an EV-1, GM's first electric vehicle, in the late 1990s. I asked Tony to what extent the Volt incorporated EV-1 technology, and his answer confirmed that while no actual parts were shared, its design philosophy and engineering DNA owe much to that earlier effort.

At first, when I drove the Volt onto the big, empty parking lot where GM had set up its test track for the DC Auto Show, I was disappointed that I didn't sense that immediate high-torque response I recalled from the EV-1--the kick that my GM contacts at the time called the "EV-1 grin." Then Tony pressed the "sport" button, and the grin was back. While my Acura might be able to beat the Volt's 0-60 miles-per-hour acceleration by several seconds, most drivers should be quite satisfied with the Volt's responsiveness and handling, even when compared to the entry-level luxury cars with which the Volt's expected price puts it into contention--and which its energy efficiency beats hands down.

The technical aspects of the Volt are fascinating, starting with the battery pack, which consists of 400 lb. of Lithium-ion batteries configured as "prismatic cells" that facilitate easier heat management than some other designs. That's a critical factor for battery life, since the battery must dissipate a fair amount of heat during its charge/discharge cycles, and its performance and efficiency are affected by ambient temperature. When plugged in, some of the energy the Volt draws from the grid is used to "condition" the battery, not just recharge it. That should help GM deliver on its expectation that the car's battery pack should last for 10 years and 150,000 miles of normal driving, over which its capacity would gradually decline, while still ultimately retaining at least 70% for later use in other, non-automotive applications. The potential after-life value of the battery could be a critical element of the lifecycle economics of a plug-in hybrid or Range-Extended Electric Vehicle like the Volt.

I was particularly interested in the battery's recharging requirements, in relation to the energy density concerns I discussed in last Tuesday's posting. The Volt recharges in two modes: At 240 V and drawing between 15-30 amps, it takes up to 3 hours to restore the roughly 50% of the battery pack's 16 kWh maximum charge used in "charge-depleting" operation--that first 40 miles or so of battery-only driving that provides the car's main selling point. Recharging on 120 V household current takes more like 8 hours. I was somewhat surprised that Tony seemed to share my view that Volt drivers are unlikely to wait until the middle of the night to recharge their cars, unless their highest priority is minimizing their electricity costs (and possibly emissions.) He has apparently been using a Volt on weekends and cited the benefits of daytime recharging at home or office to keep the battery ready for use, consistent with the main purpose of owning such a car.

The switchover from battery-only operation to driving with the onboard generator running was one of the key features I was anticipating, based on my concern that the Volt would ultimately be handicapped in low-battery, "charge-sustaining" operation by its reliance on a fairly small 4-cylinder engine. After all, the performance expectations in the category the Volt aspires to are set by powerful engines similar to the V-6 in my Acura TL, which delivers 270 peak horsepower. Well, you could have fooled me. The Volt I drove yesterday was intentionally given just enough battery charge to last about 3 miles, and when I passed that point and the little engine fired up, there was no discernible change in performance. That's apparently because the car is never really driven by the engine alone, since the battery is never completely drained. The accelerator controls only the flow of current from the battery to the electric motor; meanwhile the car's software runs the engine as needed to keep the battery charged to acceptable levels, but not to recharge it fully. That's a subtle distinction, because when I pushed the car hard in this mode, I heard the engine rev up noticeably with that characteristic 4-banger tone that provided the one discordant note in an otherwise near-luxury experience. But the trade-off was evident when I pulled the car into its tent shelter and switched it off. The cumulative fuel economy display on the dash read a whopping 910 mpg.

That result prompted an interesting discussion about what fuel economy really means in a car like this, which dutifully calculated mpg based on the tiny amount of gasoline consumed in the last lap of several miles of mostly battery-powered driving. I got a sense that GM recognizes the shortcomings of mpg in measuring such a vehicle's energy usage, though they are clearly quite focused on it as the primary metric of both consumers and the existing and proposed federal fuel economy standards. But even knowing intellectually that the car's electric efficiency, which Tony confirmed is in the range of 200-250 Watt-hours per mile, or 4-5 miles per kWh, equates to roughly 58-72 miles per gasoline-gallon-equivalent of natural gas going into a gas turbine power plant somewhere, that 910 mpg still got my attention with its implication of very rare visits to the gas station.

Recently, I indicated that while plug-in hybrids and full EVs might not yet be ready for the mass market, they do look ready for "innovators and early adopters", the folks who routinely queue up for the latest iPhone and long ago swapped out their cable set-top boxes for streaming video. If the pre-production car I drove yesterday, with the further refinements Tony Posawatz hinted would be incorporated between now and then, was any indication, the production cars that reach showrooms late this year should have early adopters salivating in anticipation, particularly with help from a federal tax credit that maxes out at $7,500 per car and for which the Volt should qualify in full. Based on his comments and my own experience with the car, there's every indication that the Volt is on track to meet its late-2010 launch target. I will be eagerly awaiting the first comment reporting that one of my readers has bought one.

Gas Electric Hybrid



Fisker Preps Its Production Car

The Karma will cost $87,900, a little more than expected, but the gas-electric hybrid is coming next November, the company says.


Fisker Automotive says it will be ready to deliver cars to customers this coming November, and will show off its production models to the public this January.
The startup, which has designed an upscale series hybrid car called the Karma, plans to show off the production version of its car at the North American International Auto Show, which starts Jan. 11 in Detroit.

The production model largely resembles the prototype that Fisker showed off at the show last year and at subsequent events. The company, though, has begun to refine the details on the price and performance of its car. As with Tesla Motors, the big question is whether Fisker can market and mass produce what will essentially be an electric car for a price that will appeal to customers and let the company also make money. The automotive world is a harsh place. You have to go back to the 1910s and 1920s to find the last time that there were successful crops of startup automakers.

The Karma will be released at a base price of $87,900, which is nearly 10 percent higher than the $80,000 price estimate given by the company earlier. The four-door car will be powered by a lithium-ion battery from an unnamed vendor and the Q-Drive power-train initially conceived by Quantum Technologies, which has worked with General Motors on a number of projects. The car will be delivered in November, a refinement from the "fourth quarter" statements earlier.

The car is a series hybrid like the Chevy Volt, which has been delayed until 2010. This type of hybrid, the car drives on an electric motor powered by batteries. When the batteries are about to give out, the gas generator fires up, and charges the batteries. The gas engine can also propel the car. The Karma itself will drive 50 miles on electricity and then drive on a combination of gas and electric power. This gives the car an estimated mileage of 100 miles per gallon, according to the company.

The car can hit a top speed of 125 miles per hour and Fisker says it can go from zero to 60 in 5.8 seconds. It also has different driving modes-Stealth, Sport, HEV and Fuel Economy, giving drivers different degrees of fuel economy and power.

Fisker and Tesla in many ways have similar strategies. Both will enter the market with high-end cars and then try to trickle into the mainstream with sedans as the underlying technology in their vehicles becomes cheaper. (CORRECTION: Tesla has already produced and sold "nearly 100" cars according to a spokeswoman. Fisker won't start until November.) The main difference is the gas generator. Fisker makes hybrids. Tesla earlier had planned to make a series hybrid but now says it will make only all-electric cars. All-electrics can cost more than regular cars because of the inordinate expense of batteries.

On the other hand, the series hybrid concept hasn't been tried in mass production cars yet. Some, including Tesla CEO Elon Musk and UC Davis Professor Andy Frank, claim that the concept is tougher to pull off than it sounds. Toyota's Prius and the other hybrids on the road are parallel hybrids. In these, the gas motor propels the car and doesn't exist to charge the battery.

As previously stated, the Karma will be assembled by Valmet Automotive, which also produces the Porsche Boxster and Porsche Cayman. The Yearly volume is anticipated to reach 15,000 cars per year.

A total of 40 retailers for the U.S. market will be established by October 2009. Fisker Automotive will announce 20 of its Retailers in January 2009. European pricing will be announced at the International Geneva Motor Show in March.


Hybrid Chevy Volt



GM's Chevy Volt: A Work in Progress

Chevy Volt co-creator Jon Lauckner says that GM's first plug-in hybrid won't have swappable or leasable batteries, but he passes on saying how much it might cost.


Fresh out of bankruptcy, General Motors promises its plug-in hybrid, the Chevy Volt, will go on sale in late 2010. What else does GM want to tell the world about it?
Jon Lauckner, Volt co-creator and GM's vice president of global program management, didn't offer too many hard answers to the dozens of questions he fielded in an online question and answer session Wednesday. But he did clarify some roads the Volt wasn't planning to travel down.

For example, GM doesn't plan to lease the Volt's batteries to customers. That's a business model being considered by some, including battery charging and swapping station, startup Better Place, since batteries can make up a significant portion of the cost of plug-in hybrid or pure electric vehicle.

Neither does GM intend to make the Volt's batteries easily removed and exchanged, Lauckner wrote. That means the Volt will not be a candidate for Better Place's switch-the-battery business model – not surprising, since Better Place is aiming more at serving all-electric vehicles.

The Volt's battery pack – being designed by GM with battery cells from a consortium headed by LG Chem. is expected to retain enough of a charge to deliver 40 miles of electric-powered range over 10 years and 150,000 miles of service, Lauckner wrote. GM will guarantee that performance and repair or replace batteries that don't meet it.

Afterwards, the battery packs should have enough energy storage capacity for stationary applications. The semi-depleted car batteries will find second homes storing energy at homes or businesses, or utility substations.

GM still isn't talking about a price for the Volt, and likely won't until three to six months before it will start production, Lauckner wrote.

The European version of the Volt, the Ampera, is still on track for a 2011 launch, but GM will also sell the regular Volt in Europe, Lauckner wrote. That was in response to a question about the future of Opel, GM's troubled European division.

And GM doesn't see much point in putting solar panels on the roof of the Volt, Lauckner wrote – unlike Toyota, which will offer buyers of the new Prius hybrid the option of rooftop solar panels made by Kyocera.

"The amount of solar energy you can get by covering the Volt's roof with solar cells is only enough to run a small fan motor," he wrote. "You aren't going to recharge the battery on solar power in a reasonable amount of time."

Toyota expects to start mass-producing a plug-in version of the Prius in 2012.

New Breed of Hybrid Cars



About Hybrid Cars

The New Breed of Hybrid Cars - Hybrid SUV

Sponsored Results for About Hybrid Cars

While hybrid cars have been around now for some time, now you can find a hybrid SUV as well, which is thrilling to many people. Some people need a bit more than a small car but they love the great benefits and features of the hybrid technology, which is why various companies are now making a hybrid SUV. These hybrid sports utility vehicles are special large vehicles that use both the power of a gas engine and an electric motor as well. This gives great power but helps to keep the vehicle fuel efficient as well. There are both mild hybrids and strong hybrids available. The mild hybrids mainly depend on gas engines and have only a small motor that is electric, while the strong hybrids have electric motors that have a larger role in powering the vehicle.


Various Models Made

There are a variety of hybrid SUV models that are being made today. Both Lexus and Toyota offer their own hybrid SUV models. You'll also find that Honda offers a hybrid SUV, but it is considered to be a very mild hybrid. While there still are not a whole variety of different hybrid SUV models being made today, in the future it is expected that more manufacturers will begin producing a variety of different SUV hybrids.

Features and Functions

There are a variety of features and functions that will come along with a hybrid SUV. Usually you will find that when you are driving at lower speeds, the electric motor will provide most of the momentum for the vehicle and the extra power is used to help recharge the batteries in the vehicle. Also, these vehicles have continuously variable transmissions in them as well, which mean that the gears shift smoothly and provide smooth power no matter which mode you are in.

A Solution to High Gas Prices

One of the best things about owning a hybrid SUV is that they can help to offer a solution for high gas prices. For those who need to drive SUVs, gas prices really have made an impact. With gas close to three dollars a gallon and SUVs getting very low gas mileage, it can definitely cramp your budget. Having a hybrid SUV can help you save on gas prices without you have to go with a car that is much smaller than what you really need. So, for those who are feeling the crunch of high gas prices, a hybrid SUV is a great option.

Great for Heavy Duty Needs

Another reason that many people are thrilled with the idea of a hybrid SUV is because it is great for heavy duty needs. It has the power needed to haul and tow, and this is especially aided b the special continuously variable transmission that offers you all the power you need at any gear level. So, for those who need something heavy duty and fuel efficient, once again the hybrid SUV is an excellent choice. 


Sport Utility Vehicles (SUV) are designed for people who want power and luxurious interior design for their cars. That is why most SUVs come with large engine capacity and a wide range of add on accessories. However, many SUV owners are in a dilemma right now because of the high gasoline prices at the local pump ...

The market for the best hybrid sports utility vehicles (SUVs) has been experiencing a steady expansion over the last few years. The reasons are not at all complex to comprehend. The best hybrid SUVS have all the good attributes of the traditional SUVs plus some additional advantages. Like all good SUV's. Telling the difference between a gas hog and a more fuel efficient vehicle when, your driving a gas only vehicle is usually pretty easy to do. You can tell which ones are better, your not only the environment but also which ones are easier on your pocket book. The ones that people usually lean towards as being the best at these.



Toyota Prius Hybrid



For 2010, Toyota has brought out an all-new version of its Prius hybrid. Like the old Prius, the new Prius is designed to deliver maximum MPG with family-car practicality. But within those parameters, Toyota has made a lot of changes: Sleeker styling, redesigned cabin, and an improved hybrid drive train that gives the driver greater control over the Prius' behavior. The old Prius did the job as well as can be expected -- so has Toyota made any meaningful improvements? Read on. $23,510 base price, $31,430 as tested, EPA fuel economy estimates 51 MPG city/48 MPG highway. 

  First Glance: I love you just the way you are


When I heard that Toyota was redesigning the Prius for 2010, my first thought was "Why?" Few cars carry out their intended mission better than the Prius. I bet Toyota could build it as-is for ten years and sales would still remain strong. But that's not the way things go in the auto business, and so change it they have: The Prius is all-new for 2010, for better or for worse. And while there is definitely some better, there is also a fair bit of worse.

Let's start with the styling. There's really not a whole lot the stylists can do with the Prius; the old model was designed to cheat the wind rather than please the eye, which pretty much dictates the shape. (That's why Honda came up with a similar profile for their own four-door dedicated hybrid, the Insight.) As a result, the new Prius looks a lot like the old Prius, at least at first glance. Look closer and you'll see a more Toyotaes-que face up front, a more pronounced wedge profile from the side, and a racy little spoiler out back. I was indifferent to the new shape at first, but the more new Priuses I see on the road -- here in Los Angeles, the Prius is as common as tall mocha lattes and silicon boobs -- the more I like the new shape. It makes the old Prius look frumpy by comparison. Overall, I'd say the new shape goes in the For Better category.



In the Driver's Seat: What were they thinking?



The Prius' cabin definitely has some For Better changes: A roomier back seat and a bigger trunk. Unfortunately, that's about all of the For Better, and there's a whole lot of For Worse.
Example numero uno is the center councel that divides the front seats. This is one design choice that has me scratching my head. Buying a Prius is all about being a good citizen of the planet -- so why design an interior that isolates the driver in his or her own little pod? The center console provides a more conventional location for the shift lever, though why anyone would possibly care is beyond me. It's an automatic, for cryin' out loud! Aside from that, the console just gets in the way. There's a storage area underneath which pretty much useless; anything you put there is going to a) block the seat heater controls -- which, by the way, are so inconveniently located that I can't believe Toyota came up with them -- and b) fall out on turns.

Example numero dos is the new instrument layout. The old Prius had a simple center-mounted digital gauge cluster. If you wanted more geeky information, like how power was flowing through the hybrid system or what sort of fuel economy you were achieving in five-minute increments, it was available on the same LCD screen that served the climate, stereo and navigation systems. The 2010 Prius still has the LCD screen, but Toyota designed a new geek-o-meter into the dashboard next to the speedometer. Problem is, they used a cheap Red and Blue LDC display, which looks cheesy and decidedly low-tech.



On the Road: Better where it counts



In terms of the mechanicals, it's all For Better. Toyota designed the new Prius to provide more power and get better fuel economy. The engine size is up from 1.5 to 1.8 liters, and there are now three driver-select power train modes: Normal, Sport and Eco. In Normal mode, the Prius drive, well, normally -- just like an old-shape Prius. Sport mode -- an odd choice of names, since there's nothing sporty about the Prius -- changes the accelerator pedal response so you get more power with less movement of the pedal. It doesn't actually make the car faster, but it does provide quicker access to what power the Prius does have.

Eco mode tunes the accelerator response to help you get maximum MPG by accelerating from a stop more gingerly and responding slowly to sudden movements of the accelerator pedal, basically automating a method used by experienced hype-rmilers to get maximum MPG. Like the old Prius, the new Prius can run on pure battery power and low speeds, and there's now an EV button that forces electric-only mode, which is useful for moving the car from one parking spot to another, but not much else.

I spent most of my time in Eco mode, figuring that most Prius owners would do the same. It worked: I averaged 48.9 MPG, a significant improvement over the 45 or so I averaged in all the second-generation Priuses I tested. I also noticed that the new Prius grips the curves better than the old Prius, although it's fun-to-drive factor is still almost nil.



Journey's End: Should be a slam dunk, but...


  The 2010 Prius has a couple of other cool gizmos, like a button on the key fob that lets you run the A/C remotely and a solar-powered ventilator fan that is supposed to keep the interior cool when the car is off (a neat idea, but it was no match for the hot Southern California sun).
But at the end of the day, the Prius is all about fuel economy, and the fact is that the 2010 Toyota Prius not only gets better gas mileage than the old Prius (as well as every other new car on the market), but it makes it easier to hit those stellar numbers. So it should be a slam dunk for the Prius... except it isn't.

Try as I might, I just can't get over the interior, with that intrusive center console and hideous dash display. I prefer the simplicity of the old Prius, even if that means getting 4 fewer miles per gallon (which, at 12,000 miles per year, only saves about 22 gallons).

Bottom line: For better or for worse, the Prius is still the best hybrid on the market. I just wish Toyota hadn't changed it quite so much.

Hybrid Electric & Fuel Cell Vehicles



Hybrid Electric Vehicles


Both technologies come together in hybrid electric vehicles, also known as HEVs or hybrids. Present-day hybrids are equipped with ICEs and electric motors. A hybrid's ICE engine, as in any ICE-powered car, produces power through continuous, controlled explosions that push down pistons connected to a rotating crankshaft. That rotating force (torque) is ultimately transmitted to the vehicle's wheels.

A hybrid's electric motor is energized by a battery, which produces power through a chemical reaction. The battery is continuously recharged by a generator that—like the alternator of a conventional car—is driven by the ICE.

Hybrids can have a parallel design, a series design, or a combination of both:

  • In a parallel design, the energy conversion unit and electric propulsion system are connected directly to the vehicle's wheels. The primary engine is used for highway driving; the electric motor provides added power during hill climbs, acceleration, and other periods of high demand.
  • Series design, the primary engine is connected to a generator that produces electricity. The electricity charges the batteries, which drive an electric motor that powers the wheels. HEVs can also be built to use the series configuration at low speeds and the parallel configuration for highway driving and acceleration.

  • In conventional vehicles, energy from deceleration is wasted as it dissipates. In some hybrid vehicles, regenerative braking systems capture that energy, store it, and convert it to electricity to help propel the vehicle—ultimately increasing overall efficiency. Some hybrids also use ultracapacitors to extend the life of a hybrid vehicle's on-board battery system because they are better suited to capturing high power from regenerative braking and releasing it for initial acceleration.

    Hybrid passenger cars arrived in the United States in model year 2000, following their introduction in Japan a few years earlier. First came the two-seat Honda Insight, followed by the Toyota Prius in model year 2001. Honda then introduced a hybrid version of its Civic sedan, and Toyota offered a second-generation Prius. Ford plans to introduce its first hybrid, a version of the Escape sport utility vehicle, in model year 2005. Several other major automakers now either offer HEVs or plan to do so in the near future. Hybrid systems have also proved effective in buses and heavy trucks. For example, Oshkosh Truck Corporation has demonstrated a diesel-electric system that may significantly improve the fuel economy and driving range of military vehicles. As a bonus, hybrids can be devised to generate alternating current electricity for other applications such as plug-in power tools. General Motors, through its Allison Transmission Division, produces a diesel-electric hybrid drivetrain for transit buses.

How Hybrid Electrics Work


Hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.





OVERVIEW

Hybrid-electric vehicles combine the benefits of gasoline engines and electric motors to provide improved fuel economy.
The engine provides most of the vehicle's power, and the electric motor provides additional power when needed, such as for accelerating and passing. This allows a smaller, more-efficient engine to be used.
The electric power for the motor is generated from regenerative braking and from the gasoline engine, so hybrids don't have to be "plugged in" to an electrical outlet to recharge.

Some of the advanced technologies typically used by hybrids include:

Regenerative Braking.The electric motor applies resistance to the drivetrain causing the wheels to slow down. In return, the energy from the wheels turns the motor, which functions as a generator, converting energy normally wasted during coasting and braking into electricity, which is stored in a battery until needed by the electric motor.


Electric Motor Drive/Assist. The electric motor provides additional power to assist the engine in accelerating, passing, or hill climbing. This allows a smaller, more efficient engine to be used. In some vehicles, the motor alone provides power for low-speed driving conditions where internal combustion engines are least efficient.

Automatic Start/Shutoff. Automatically shuts off the engine when the vehicle comes to a stop and restarts it when the accelerator is pressed. This prevents wasted energy from idling.

Hybrid Electric Car Technology



2010 Toyota Prius Hybrid Electric Car Technology Exposed


Yountville, Calif. The eagerly awaited details of the 2010 Toyota Pruis are slowly emerging. We already provided an overview of the car after it was revealed at the Detroit Auto Show. Last week, we were in Napa Valley, where Toyota released technical details what will make this vehicle hum (but not too loudly). –Larry Webster
The Engine

Mechanically, the biggest changes for the most popular hybrid electric on the market are in the engine room. The 1.5-liter gas engine is out in favor of a 1.8-liter unit. This larger engine still operates with the late-intake-valve-closing Atkinson cycle, and it produces more lower-end torque. This engine also operates at lower speeds, a fuel-saving move that offsets the larger displacement. There is an electrically operated water pump, which allowed engineers to remove the drive belt and the accompanying parasitic loss from the motor. As before, the crankshaft is offset in relation to the cylinders to reduce friction.

Engine coolant circulates to a heat exchanger that encircles the exhaust just downstream of the catalytic converter. This feature heats the engine up sooner, so it can be warmed up and turned off promptly. Also, it provides quick cabin heat. An aggressive exhaust-gas recirculation system employs cooled exhaust gas that's pumped into the cylinders. The inert gas replaces the intake charge, reducing exhaust-gas temperature and pumping losses.

The Transmission

The Hybrid Synergy drive system uses the same planetary Continuously Variable Transmission as before, but with a new twist. The main electric motor drive, called MG2, was downsized and produces less torque (153 lb-ft versus 295). But a reduction gear-set that connects it to the gearbox allows the MG2 to spin to 13,500 rpm, 7100 higher than before. Consequently, it makes 80 peak horsepower, 13 greater than before. The smaller, lighter MG2 and other refinements in the drive system yielded a 66-pound weight saving.

The Battery

A nickel-metal-hydride battery pack returns. It's been shrunk slightly, but a more effective cooling system allowed a peak output rise from 25 kilowatts to 27 (battery voltage remains at 201.6 volts). The inverter converter has been improved—it's slightly smaller—and provides up to 600 volts of AC current, a 100-volt jump. Toyota has also added a feature many Prius buyers have been waiting for—an electric-only button. Pressing this button on the dash prevents the gas engine from starting until the battery is depleted. Electric-only mileage, however, is slight—on average, a mile. For longer battery-powered runs, we'll have to wait for the rumored plug-in version; it should appear within two years.

Horsepower and Fuel Economy

The total maximum output of the engine and electric motor is 134 hp, 20 higher than before. That should drop the 0-to-60-mph sprint by about a second to 9.5 seconds. Despite the increased pace, the fuel economy has been improved, jumping from 48/45 city/highway to 50/49.

That fuel economy increase is all the more incredible considering that the new car weighs about 110 pounds more, a consequence of meeting tougher crash regulations. For sure, the car's aerodynamics play a role in increasing the on-road efficiency. Airflow around the Prius is carefully managed with flat underside panels, bumper-mounted air deflectors, and that gently sloping rear hatch. The drag coefficient has been reduced to only 0.25.

High-Tech Extras

Toyota left some of the most high-tech stuff outside of the mechanicals. Buyers can opt for the Lane Keep Assist system that detects when the car goes out of a lane and automatically nudges the steering wheel to stay on course. A pre-collision system works in conjunction with radar cruise control to avoid an impending collision by applying the brakes. An optional roof-mounted solar panel powers the fan and keeps a parked Prius cool, reducing the draw on the air conditioning. The new Prius can even Parallel Park itself with the Intelligent Parking Assist. There are also items we're not used to seeing in hybrids, such as leather, power and heated seats, voice-activated navigation and Bluetooth connectivity.

Prices have not yet been released, but expect the base Prius to start around $24,500. Fully loaded, we wouldn't be surprised to see the Prius clear 30 grand.

Electric Revolution



Electric Car Revolution Will Soon Take to the Streets





For years, the promise and hype surrounding electric cars failed to materialize. But as this year's Detroit auto show demonstrated, major car companies and well-funded startups — fueled by federal clean-energy funding and rapid improvement in lithium-ion batteries — are now producing electric vehicles that will soon be in showrooms.

Media gather around the new Tesla Model S all-electric sedan car, at the car's unveiling in Hawthorne, California on 26 March 2009. Musk said the state-of-the-art, five-seat sedan will be the world's first mass-produced, highway-capable electric car. Photograph: Robyn Beck/AFP/Getty Images

Electric cars are a green movement that is finally moving. Shunted to the side as the public indulged its love affair with gas-guzzling SUVs and four-wheel-drive trucks, history has finally caught up with the plug-in vehicle.

The North American International Auto Show in Detroit is the domestic auto industry's biggest annual showcase, and the new models have traditionally been brought out in a son et lumière of dancing girls, deafening music, and dry ice smoke. The few green cars that made it this far were usually for display only — very few actually made it to showrooms.

But not this year. It's become a race to market for green cars, and soon you'll be able to buy many of the electric vehicles that were on display last week in Detroit. The auto show featured one hybrid and battery electric car introduction after another. Although the only truly road-worthy, plug-in electric vehicle you can buy today is the $109,000 Tesla Roadster, by the end of 2010 it will be joined by such contenders as the Nissan Leaf, Coda sedan, and the Think City.

Indeed, the entire auto industry — from giants such as Ford, GM, and Renault-Nissan to startups such as Fisker Automotive — has joined the movement to build and market affordable electric vehicles.

There's a reason the automakers in Detroit are finally plugging in as something more than a greenwashing exercise. Spurring them forward is a historic confluence of events. Chief among them are Obama administration green initiatives, including Department of Energy (DOE) loans and grants, as well as economic stimulus funds that provide $30 billion for green energy programs, tax credits for companies that invest in advanced batteries, and $2.4 billion in strategic grants to speed the adoption of new batteries. (Much of that money is going to Michigan, which despite record unemployment is emerging as something of a green jobs center.)

Other factors behind the push to manufacture electric vehicles are a federal mandate to improve fuel efficiency to an average of 35.5 miles per gallon by 2016, concerns about global warming and peak oil, and sheer technological progress building better batteries.

Even without federal largesse, some companies are moving aggressively into the electric vehicle market. A prime example: Coda Automotive, a southern California start-up, has raised an impressive $74 million in three rounds of private funding. CEO and President Kevin Czinger is a former Goldman Sachs executive, as is co-chairman Steven Heller. Among the company's investors are Henry M. Paulson, who was Goldman Sachs' chairman and Treasury Secretary under the second President Bush. Clearly, these former investment bankers see electric cars as a good bet.

A key factor in making today's electric vehicles possible is the rapid development of the energy-dense lithium-ion battery. William Clay Ford Jr., the executive chairman of the company that bears his name, told me in Detroit, "Five years ago, battery development had hit a wall, and we were pushing hydrogen hard. But now so much money and brainpower has been thrown at electrification that we're starting to see significant improvements in batteries in a way we hadn't anticipated. Now we have the confidence that the customer can have a good experience with batteries."

Drawing a huge crowd, Tesla Motors Chairman and CEO Elon Musk showed off his company's 1,000th electric Roadster at the auto show. "For a little company, it's a huge milestone," he told me. "A year ago, we had built only 150 cars. We had two stores then, and now it's a dozen."

For a major automaker, 1,000 cars would not be much to show for a year, but electric vehicles are still in their infancy. And since the electric car's first swan song in the 1920s — when the widespread availability of petroleum ushered in the era of the gasoline-powered car — very few start-up companies have reached the milestone of making green vehicles, especially battery-powered ones.

Here's a look at some of the prime contenders bringing battery cars and plug-in hybrids to market:

* Renault-Nissan Alliance. This is the one automaker with a truly global plug-in strategy and the means to carry it out. Under the Nissan banner, the company will deploy the Leaf battery sedan, with 100-mile, all-electric range. Nissan isn't just dumping its sleek entry into the market — it's also building a home charger with new partner AeroVironment and partnering with local, state and federal governments — both in the U.S. and abroad — on public charging stations. In partnership with Better Place, the company will deploy a second Renault electric vehicle as part of its plan to wire up Israel with charging stations for electric cars. Renault-Nissan chief Carlos Ghosn predicts that electric vehicles could constitute 10 percent of world car sales by 2020.

* Ford Motor Company. Ford's green strategy includes a plug-in version of the new Focus for 2011 and a "next-generation" hybrid — based on its global compact-car platform, or C-platform — in 2012. The company announced in Detroit that it would invest $450 million in Michigan as part of its electrification strategy. Michigan Governor Jennifer Granholm told me at the auto show that until recently the state "wasn't sure it had a viable auto industry." Today, she said, the state is enjoying $1 billion in new auto-related investment, much of it jump-started by a combination of federal funding and state tax credits.

* General Motors. GM's big news is the Chevrolet Volt, which has definitely helped the company's image. The Volt, which uses a small gas engine to generate electricity for its electric motor, is a lot of fun to drive if the version I drove recently in Michigan is any indication. Until now, GM has stumbled in its hybrid strategy, and it really needs this car — which will go on sale at the end of the year for a hefty $40,000 — to be a hit. But success may be more a matter of perception than actual sales. "In terms of numbers, the Volt will be pretty small for the first couple of years," says product chief Bob Lutz. A Cadillac version of the Volt is also a possibility.

* Tesla Motors. This California start-up launched at the top of the market with its $109,000 Roadster, which combines sexy looks with supercar performance (zero to 60 in 3.9 seconds). The company is on something of a roll, having sold 10 percent of itself to Daimler for $50 million, and landed $465 million in DOE funding for its forthcoming Model S sedan — a Maserati-like, more practical version of the Roadster. Tesla's Musk says that the company's strategy has always been to use its sale of performance cars to finance its third vehicle, a mass-market electric vehicle. The company is currently looking at California locations for a Model S factory.

* Fisker Automotive. Perhaps Tesla's closest competitor when it comes to glamour electric vehicles, Fisker – whose CEO is Danish-born automotive designer Henrik Fisker — is preparing to debut a high-performance plug-in hybrid (zero to 60 in 5.8 seconds, with 67 mpg fuel efficiency) known as the Karma at the end of the year. Al Gore is on the waiting list. Fisker also has a lower-cost car in the wings, called Project Nina. Fisker won $528 million from the DOE to build the Nina in a former GM factory in Delaware.

* Coda Automotive. This start-up will deliver, in late 2010, a small battery-powered sedan with batteries from its own joint venture in China. The car is based on the Saibao, a Chinese car, but Coda has put a host of western companies to work honing an electric drivetrain for it. "A large part of our mission is to accelerate adoption of all-electric vehicles," Coda CEO Kevin Czinger told me. "We have put together a core group of auto and battery engineers, and are leveraging specialty automotive firms that we think can get us to the right price point." Coda will launch with an Internet marketing strategy in California only, but it will have the capacity to produce 20,000 cars a year.

* Think Global. Think is a survivor, with perhaps the longest and most colorful history among green automakers. It is a Norwegian company that attracted Ford Motor Company investment in the late 1990s with its plastic-bodied City commuter car. Ford sold the company in 2003 and it went through bankruptcy proceedings in late 2008. It has since emerged under the partial ownership of U.S. battery company Ener1, which snagged $118 million in DOE funding to expand its battery production in Indiana. Think electric vehicles will also be built there starting in 2011, in hard-hit Elkhart — once proudly known as the "RV Capital of the World" — and now suffering the effects of the recession. The two-seat Think City (with approximately 100-mile range on lithium-ion batteries) will sell for less than $20,000 in the U.S., but that price does not include the leased battery pack and includes the $7,500 federal tax credit for electric vehicles.

The list of players in the electric vehicle race goes on. Toyota is building plug-in hybrids and fuel-cell vehicles, and showed off a small cousin of the Prius in Detroit. Chrysler has an ambitious electric vehicle rollout that's been stalled by the company's bankruptcy and merger with Fiat. Honda continues to deploy clever hybrid cars, including the upcoming two-seat CR-Z it showed in Detroit. BMW has electrified the Mini for a test program, and has similar intentions for the Concept ActiveE, a plug-in version of the Series 1 BMW coupe. And Audi has shown sudden interest in this segment, debuting the second of its electric e-tron vehicles.

By this time next year, electric cars will no longer be just on auto show stands, but will have arrived in showrooms at last.



Air Power


Air-Powered Car Coming to U.S. in 2009 to 2010 at Sub-$18,000, Could Hit 1000-MileRange

The CityCAT, already being developed in India , will be available for U.S. production in three different four-door styles. But it's the radical dual-energy engine, with a possible 1000-mile range at 96 mph, that could move the Air Car beyond Auto X Prize dreams and into American garages.



Zero Pollution Motors (ZPM) confirmed to PopularMechanics.com on Thursday that it expects to produce the world's first air-powered car for the United States by late 2009 or early 2010. As the U.S. licensee for Luxembourg-based MDI, which developed the Air Car as a compression-based alternative to the internal combustion engine, ZPM has attained rights to build the first of several modular plants, which are likely to begin manufacturing in the Northeast and grow for regional production around the country, at a clip of up to 10,000 Air Cars per year.

And while ZPM is also licensed to build MDI's two-seater One CAT economy model (the one headed for India) and three-seat Mini CAT (like a Smart For Two without the gas), the New Paltz, N.Y., startup is aiming bigger: Company officials want to make the first air-powered car to hit U.S. roads a $17,800, 75-hp equivalent, six-seat modified version of MDI's City CAT (pictured above) that, thanks to an even more radical engine, is said to travel as far as 1000 miles at up to 96 mph with each tiny fill-up.

We'll believe that when we drive it, but MDI's new dual-energy engine—currently being installed in models at MDI facilities overseas—is still pretty damn cool in concept. After using compressed air fed from the same Airbus-built tanks in earlier models to run its pistons, the next-gen Air Car has a supplemental energy source to kick in north of 35 mph, ZPM says. A custom heating chamber heats the air in a process officials refused to elaborate upon, though they insisted it would increase volume and thus the car's range and speed.

"I want to stress that these are estimates, and that we'll know soon more precisely from our engineers," ZPM spokesman Kevin Haydon told PM, "but a vehicle with one tank of air and, say, 8 gal. of either conventional petrol, ethanol or bio-fuel could hit between 800 and 1000 miles."

Those figures would make the Air Car, along with Aptera's Typ-1 and Tesla's Roadster, a favorite among early entrants for the Automotive X Prize, for which MDI and ZPM have already signed up. But with the family-size, four-door City CAT undergoing standard safety tests in Europe, then side-impact tests once it arrives in the States, could it be the first 100-mpg, nonelectric car you can actually buy?

World's First Air-Powered Car: Zero Emissions by Next Summer 
India's largest automaker is set to start producing the world's first commercial air-powered vehicle. The Air Car, developed by ex-Formula One engineer Guy Nègre for Luxembourg-based MDI, uses compressed air, as opposed to the gas-and-oxygen explosions of internal-combustion models, to push its engine's pistons. Some 6000 zero-emissions Air Cars are scheduled to hit Indian streets in August of 2008.

Barring any last-minute design changes on the way to production, the Air Car should be surprisingly practical. The $12,700 CityCAT, one of a handful of planned Air Car models, can hit 68 mph and has a range of 125 miles. It will take only a few minutes for the CityCAT to refuel at gas stations equipped with custom air compressor units; MDI says it should cost around $2 to fill the car's carbon-fiber tanks with 340 liters of air at 4350 psi. Drivers also will be able to plug into the electrical grid and use the car's built-in compressor to refill the tanks in about 4 hours.

Of course, the Air Car will likely never hit American shores, especially considering its all-glue construction. But that doesn't mean the major automakers can write it off as a bizarre Indian experiment — MDI has signed deals to bring its design to 12 more countries, including Germany, Israel and South Africa.
