2009 Toyota Prius

The Toyota Prius continues into 2009 as the best-selling gas-electric hybrid vehicle in the U.S. and the world.

As other carmakers begin to introduce hybrid vehicles, the Toyota Prius is in its second generation and 11th year of production. More than one million have been sold worldwide.

Prius delivers exceptional fuel efficiency. Hybrid Synergy Drive is a "full hybrid" system, which means it is capable of operating in gas or electric modes, as well as a mode that combines the power of the gas engine and electric motor.

In the Prius, Hybrid Synergy Drive combines a 1.5-liter four-cylinder Atkinson Cycle gasoline engine and electric drive motor. The gasoline engine produces 76 horsepower and 82 lb.-ft. of torque.

The permanent-magnet electric drive motor produces its maximum power of 50 kW (67 horsepower) from 1,200-1,540 rpm, and peak torque of 295 lb.-ft. from 0-1,200 RPM. The Prius produces 110 combined horsepower with its gas engine and electric motor.

The Prius rides on a 106.3-inch wheelbase that yields generous interior room and a smooth ride. Its 0.26 coefficient of drag helps to minimize interior noise and enhance fuel mileage.

The liftback design gives the Prius outstanding cargo capacity and flexibility. Rear cargo room measures 14.4 cubic feet.
