The Prius actually has two engines: a 76 HP, 1.5 liter four-cylander, gas-powered engine, and a battery-powered 67 HP motor. The electric motor gets the car going up to about 30 mph then the gas engine takes over. The battery is charged whenever the vehicle slows down. Toyota markets this complicated system as "Synergy Drive." | The Prius actually has two engines: a 76 HP, 1.5 liter four-cylander, gas-powered engine, and a battery-powered 67 HP motor.
