There have been many efforts to innovate automobile design funded by the NHTSA, including the work of the NavLab group at Carnegie Mellon University. Recent efforts include the highly publicized DARPA Grand Challenge race.Relatively high transportation fuel prices do not significantly reduce car usage but do make it more expensive. One environmental benefit of high fuel prices is that it is an incentive for the production of more efficient (and hence less polluting) car designs and the development of alternative fuels. At the beginning of 2006, 1 liter of gasoline cost approximately $0.60 USD in the United States and in Germany and other European countries nearly $1.80 USD. With fuel prices at these levels there is a strong incentive for consumers to purchase lighter, smaller, more fuel-efficient cars. Greenpeace, however, demonstrated with the highly fuel efficient SmILE that car manufacturers aren't delivering what they could and thus not supplying for any such demand [citation needed]. Nevertheless, individual mobility is highly prized in modern societies so the demand for automobiles is inelastic. Alternative individual modes of transport, such as Personal rapid transit, could serve a an alternative to automobiles if they prove to be cheaper and more energy efficient.Lexus LF-A concept car at the 2006 Greater Los Angeles Auto ShowEnlargeLexus LF-A concept car at the 2006 Greater Los Angeles Auto ShowElectric cars operate a complex drivetrain and transmission would not be needed. However, despite this the electric car is held back by battery technology - a cell with comparable energy density to a tank of liquid fuel is a long way off, and there is no infrastructure in place to support it. A more practical approach may be to use a smaller internal combustion (IC) engine to drive a generator- this approach can be much more efficient since the IC engine can be run at a single speed, use cheaper fuel such as diesel, and drop the heavy, power wasting drivetrain. Such an approach has worked very well for railway locomotives, but so far has not been scaled down for car use.Subaru Cadillac Kia Mazda Lada Mercedes-Benz Mercedes-Benz Fiat Ssang Yong Ssang Yong Porsche Scania Jaguar Iveco Nissan Saab Subaru Ford Porsche Jaguar Saab Renault Fiat Cadillac Audi Mercedes-Benz Toyota Audi Opel Ssang Yong Opel Chrysler Ssang Yong Jeep Alfa Romeo Alfa Romeo Ssang Yong Hyundai Volkswagen MAN Mitsubishi Toyota Mercedes-Benz Mazda Chevrolet Jaguar Volvo Ford Jaguar Ssang Yong Jeep Honda Kia Mercedes-Benz Audi Toyota Volkswagen Volkswagen Jaguar Scania Jaguar Skoda Iveco Alfa Romeo Daewoo Pontiac Mitsubishi Pontiac Pontiac Chrysler Iveco Fiat Rover Seat Ssang Yong Renault Kia Lada Suzuki Pontiac Ssang Yong Lexus Peugeot Ford Kia Nissan BMW Saab Skoda Hyundai Honda Fiat Saab Chrysler Skoda Alfa Romeo Nissan DAF Suzuki Scania Pontiac Nissan Fiat Suzuki Citroen Mitsubishi Alfa Romeo Iveco Lexus Cadillac Skoda Lada Chevrolet Land Rover Jaguar Dodge Volvo Seat Skoda Fiat Chevrolet Jeep Dodge Land Rover Audi Lexus Alfa Romeo Scania Kia Saab Subaru DAF Volkswagen Mazda Mercedes-Benz BMW Mitsubishi Daewoo Nissan Dodge MAN Toyota Rover Jeep DAF Jeep MINI Kia Daewoo Ssang Yong Seat Pontiac Saab Daewoo Nissan Skoda Daewoo Kia Cadillac Pontiac Ford Daewoo Citroen Volvo Hyundai Volvo Saab DAF MAN Alfa Romeo Daewoo Citroen Alfa Romeo Scania Seat Lada BMW Honda Ssang Yong Toyota Lexus Alfa Romeo Mazda Rover Honda Citroen Fiat Saab Skoda Audi Iveco Pontiac Cadillac Volkswagen Volvo Pontiac Dodge Iveco Lexus Audi BMW Subaru Ssang Yong BMW Mitsubishi Mercedes-Benz Porsche Kia Saab Ssang Yong Audi Scania Volkswagen Mercedes-Benz Ssang Yong Peugeot Fiat Dodge Scania Hyundai Dodge DAF Chevrolet BMW Lada Fiat Fiat BMW Suzuki Dodge Daewoo Chrysler Daewoo Ford Iveco Mitsubishi Fiat Pontiac Chrysler Porsche Jaguar MAN Seat Honda Saab Lexus Mitsubishi Alfa Romeo Chrysler Suzuki Land Rover Lada Toyota DAF Hyundai Lexus Porsche Audi Jaguar Subaru Land Rover Volkswagen Seat Daewoo Ford Rover Suzuki Skoda Skoda Lada Fiat Jeep MAN Citroen Audi Mercedes-Benz Ssang Yong Skoda Ssang Yong Jeep Cadillac Nissan Nissan DAF Nissan Citroen Chrysler Porsche Suzuki Scania Fiat Hyundai Honda Lexus Jeep Ford Porsche MINI MAN Porsche Lada Audi Volvo Hyundai Mitsubishi DAF Alfa Romeo Chrysler Toyota Mercedes-Benz Honda Subaru Alfa Romeo Subaru Land Rover Nissan Ford MAN Suzuki Saab BMW Nissan Porsche Ford Chevrolet Honda Alfa Romeo Opel Scania Opel Chrysler Volkswagen Ssang Yong Citroen Pontiac Seat Volvo Audi MINI Lada Porsche Volkswagen Fiat Saab Nissan Honda Toyota Land Rover DAF BMW MINI Jeep Toyota Cadillac MAN Opel Mitsubishi Lada Honda Peugeot Nissan Chrysler Nissan DAF Ford Hyundai Land Rover Iveco Lada Jeep Scania MAN Cadillac Seat Hyundai Chrysler Chrysler DAF Peugeot Dodge Fiat Porsche Renault Land Rover Cadillac Lexus Audi Hyundai Subaru BMW Renault
