As with many of Toyota's vehicles, the Prius has become a standard-bearer in its segment. While many automakers have yet to even develop a gasoline-electric hybrid vehicle, Toyota is already on its third generation of the Prius. This four-door hybrid has become a hit with consumers because of its stellar fuel economy, relatively uncompromised driving and acceleration characteristics and reasonable price.The Toyota Prius (its name comes from Latin and means "to go before") exists as a partial solution to the automobile's problem of tailpipe emissions. The Prius, like other hybrid vehicles, has a special powertrain that combines a gasoline-fueled internal combustion engine with an electric motor. This powertrain, along with other advanced features, allows the Prius to deliver higher fuel economy and lower emissions compared to regular cars.Due to its popularity and relatively long sales history, Toyota's original hybrid car is a strong candidate for a shopper interested in a used hybrid vehicle. So far, it seems Toyota's reputation for reliability and durability is holding true for the Prius. Early concerns about long-term durability have turned out to be mostly unfounded. However, potential buyers of a used Prius should take extra care during the research process. As the Toyota Prius is quite complex, future repairs and part replacements could be quite expensive.The Toyota Prius was completely redesigned for 2010. However, it remains a four-door hatchback that seats five people. The car's hybrid powertrain consists of a 1.8-liter gasoline engine that produces 98 horsepower and 105 pound-feet of torque that's used in conjunction with two electric motors and a special planetary gearset that functions as a continuously variable transmission (CVT). Total system power is 134 hp.Under full acceleration, both power sources work together to provide maximum oomph. But under lighter load conditions such as stop-and-go traffic, the Prius alternates between the two, often running on battery power alone. This maximizes the car's fuel economy potential. A regenerative braking system converts energy normally lost as heat into electricity to charge the car's battery pack. The current powertrain is a little more robust on the highway than the previous-generation car, although not really any quicker away from a traffic light. It is more fuel-efficient, however, with an EPA combined fuel economy estimate of 50 mpg -- which is tops in the hybrid game.
