When we look at an automobile, we are moved by what we see on the outside – its styling. But what moves the car is on the inside – its engine. Please join us for a rare look under the hoods of some of the finest automobiles at Henry Ford Museum. More than 40 cars have their engines exposed for you.

Engines Exposed: 2002 Toyota Prius

Gasoline Engine: Inline 4-cylinder engine, double overhead cam, 91 cubic inches displacement, 76 horsepower

Electric Motor: AC, permanent magnet, 33 kilowatt, 44 horsepower

Hybrid cars are an old idea, but their moment arrived with the Toyota Prius. The car’s gas and electric power plants sit side-by-side. The electrical inverter, on top of the electric motor, converts DC current from the batteries into AC used by the motor. That motor becomes a generator during braking, turning kinetic energy from the car’s momentum into electricity fed back to the batteries.
