The soaring oil prices and the rising level of awareness among the masses regarding the rapidly deteriorating environmental conditions are compelling many car makers to switch over the developing hybrid cars. There are already more than one million hybrid vehicles running on American roads (May, 2008). Big car companies like GM and Toyota have already made big strides in this direction. In fact GM is cutting down on producing and marketing its behemoth gas-guzzling trucks and focusing more on lighter, fuel-efficient cars. The number one selling hybrid car is Toyota’s Prius. Incidentally, Toyota is far ahead in the race for producing hybrid cars.
