Hybrid Autos

In 2004 when MSN Autos first published "What is a Hybrid," car buyers were struggling to understand concepts like electric motors helping a gasoline engine and regenerative braking. Then, there were just six hybrid models offered: the two-seat Honda Insight; two compact sedans, the Toyota Prius and Honda Civic Hybrid; Ford's small Escape Hybrid SUV; and the Chevrolet Silverado Hybrid full-size pickups. By the end of 2008 there will be 20 hybrid models available, including a full-size pickup, full-size sport-utility vehicles and an ultra-luxury sedan priced north of six figures. But just as drivers are beginning to become comfortable with the technology, the long lineup of experimental and prototype hybrid systems being developed four years ago are ready, or nearly ready, for prime time—including three that use no electricity. Regardless of a hybrid system's design, each combines two sources of power to achieve the same results in varying degrees, increase fuel economy and reduce harmful emissions. While hybrid vehicles haven't exactly swept the automotive world, it's clear they have muscled their way into consumer acceptance and have grabbed the attention of automakers. It's also clear that electricity in the drivetrain isn't the only way to hybridize a vehicle. Larry E.
