This isn’t a new engine technology; rather, it’s Hyundai’s strategy to reach a fleet average of 35 mpg by 2015. It includes the 2010 Sonata hybrid, high-mileage “Blue” versions of the 2009 Accent and Elantra, and a future crossover with a gasoline direct-injection engine.

Ford Hybrid:Ford Escape and Mercury Mariner SUVs
Ford brought the all new 2010 Fusion hybrid and 2010 Mercury Milan hybrid to L.A. The cars are nearly identical but for a few styling cues and trim levels, and they share the new lighter hybrid system found in the current Ford Escape and Mercury Mariner SUVs. The cars can go 47 mph on electric power only, according to Ford.

Hydrogen Fuel: Honda FCX Clarity Sedan
Honda unveiled the FCX Clarity fuel cell vehicle at the 2007 Los Angeles Auto Show, and an announced that a limited number of southern Californians will have the opportunity to lease one next summer. This is the first time a customer can obtain a fuel cell car directly from a retail dealer. The company is also showing progress with the creation of a hydrogen home fueling station.
A lease on the Honda FCX Clarity will cost $600 per month, including service, maintenance, and collision insurance. The term on the lease will be three-years.
In terms of appearances, the futuristic four-door Clarity will closely resemble the FCX concept, aside from some minor front-end design modifications. The Clarity will be powered by a hydrogen fuel cell stack—running along the car’s center tunnel between the front seats—that generates electricity but produces zero exhaust emissions at the tailpipe. Functional improvements in the FCX Clarity over the previous concept model include a 20 percent increase in fuel economy, a 30 percent increase in vehicle range to 270 miles, and an advanced new lithium-ion battery pack that is 40 percent lighter and 50 percent smaller.
Hydrogen fuel-cell: Honda FCX Clarity
For a nearly a generation, hydrogen fuel-cell vehicles have been championed as the long-term solution to auto emissions. Vehicles like the Honda FCX Clarity and the Chevrolet Equinox have brought that dream a little bit closer to reality. But the BMW Hydrogen 7 steers through the hydrogen highway in a different direction—because it isn’t a fuel-cell vehicle at all.
Instead of using hydrogen to generate electricity in a fuel cell, the BMW Hydrogen 7— essentially a 7 Series sedan—burns hydrogen in its conventional V-12 engine. And it can switch to straight gasoline at the driver’s whim. Think of it as a dual-fuel gasoline-hydrogen hybrid. A full tank of liquid hydrogen will grant a vehicle range of more than 125 miles. Add a full tank of gasoline for another 300 miles of interstate driving. Put those two together and the BMW Hydrogen 7 can drive about 450 miles on a full supply of fuel.
Whether using an engine or fuel cell, burning hydrogen produces only water vapor at the tailpipe. But the Hydrogen 7 faces a number of obstacles that fuel-cell vehicles—already challenged enough—don’t have to consider.
Sedan Hybrid: Lexus LS 600h L
If solar panels on Al Gore’s 20-room mansion and Vanity Fair’s 300-page annual green issue make you feel queasy about the eco-chic spin on our sustained environmental and energy crisis, then the Lexus LS 600h L might make you feel downright nauseous.
The Top 10 list of why the Lexus LS 600h L is the most bizarre and misguided hybrid:
1. A hybrid powertrain on a 5-liter V8 engine.
2. 430 horsepower (equivalent of 6-liter V12).
3. City/highway mileage rating in the low 20s.
4. 70-percent cleaner emissions than the “cleanest” of its V8 competitors.
5. Noise and vibration levels are about half of conventional cars. (“This is the kind of vehicle that travels slightly detached from the road, the local environment, and anyone else that doesn’t have a near 7-digit income,” writes Art Vatsky in AutoBlogGreen.)
6. Since you can’t hear anything outside the cabin, the vehicle uses two-cameras and a radar system to detect approaching objects and humans. A third camera mounted on the steering column monitors if the driver’s head is turned to the side. If a car, object, or pedestrian gets too close, the “advanced pre-collision system” alerts the driver with a chime and a flashing light.
7. Each vehicle is hand-sanded twice during the painting process.
8. Lexus aims to sell 1,200 to 2,000 units in the U.S. (Is this profitable for Lexus?)
9. Starts at $104,000. (At this price, you could buy four Priuses, keep one for yourself, and give three away as cute gifts).
10. The Lexus LS600h L is an amazing showcase of Lexus’s creativity and technological sophistication—all applied to a vehicle that is completely out-of-step with our times.
If any of our more affluent readers are thinking about the Lexus LS600 L, by all means, have some fun. But don’t kid yourself that you are doing anything to help the world.
Along Body: Chevrolet Tahoe Hybrid
The Chevrolet Tahoe Hybrid, along with its GMC counterpart, the Yukon Hybrid, are the first vehicles to utilize the advanced two-mode hybrid powertrain developed jointly by BMW, DaimlerChrysler, and General Motors. This full-size SUV launches a new breed of larger vehicles that are significantly greener than their gas-powered versions. Maybe that's why the Tahoe Hybrid received the questionable title of “Green Car of the Year” at the 2007 Los Angeles Auto Show. The panelists may have jumped the gun a little, as this hybrid doesn’t even meet the corporate average fuel economy (CAFE) standard.
The crux of the Tahoe Hybrid’s powertrain is GM’s 6-liter Vortec V8 with cylinder deactivation technology. In other words, this engine can shut down four of its eight cylinders when the additional power is not needed. That saves fuel. Beyond the engine, there’s a 300-volt battery that hides below the second-row seats. The vehicle's two electric motors are housed within the transmission.
In order to keep the vehicle running at peak efficiency, this hybrid system is able to run in one of two separate modes—hence the name "two-mode hybrid." For low-speed, low-impact driving, the powertrain works just like other hybrids; it stops the V8 engine whenever possible so that it may draw power from one or both of the electric motors. The second mode is mostly for highway driving, at which time one or both electric motors can run concurrently along with the V8 engine in order to provide a power boost. The two-mode transmission is the key to the whole system, which attempts to keep the engine running at the optimum rpm for low fuel consumption. Essentially, it manages a balancing act between the V8 engine and the electric motors. It is also responsible for making the transitions between the two modes practically seamless
Lexus GS 450h Hybrid Sedan
Automobile shoppers can get a taste of the F1 gas-hybrid future today—by driving the new Lexus GS 450h sedan.
While it'll never compare with Formula 1 cars for speed, this gas-electric hybrid provides race-car-like acceleration and luxurious appointments in the same package.
The Hermes of Hybrids
Slip behind the wheel of this $55,000 machine, and "hybrid" will be the first—and last—thoughts that come to mind. First you'll note, with geeky chic, that the car has not a tachometer but a "kW" gauge for—that's right—kilowatts. A display near the 160 mph speedometer shows a battery in various stages of charge. The center console's screen will toggle to hybrid mode and display your energy consumption.
And consume you will. Ever so gently depress the accelerator and the GS will stalk silently to 15 mph on full electric mode. But mash the go pedal, and five Mississippi's later you're passing 60 mph—a fraction of this car's top speed—and looking for gobs of open pavement ahead for decidedly un-environmental antics.
See, the GS 450h is perhaps the purest expression of power harnessed for the "no compromises" side of the hybrid ledger. Toyota mated a high-output, electric motor-generator rated at 197 horsepower with a 297-horsepower, 24-valve, 3.5-liter gasoline engine to yield the Hermes of hybrids, a 339-horsepower brute (don't ask; Toyota wizardry at work here) that motivates this 4,100-pound luxury sedan.
