How Hybrid Cars Work

A hybrid car is a passenger vehicle that combines two or more sources of power, usually gasoline and electricity. The two types of gasoline-electric hybrid cars are the parallel and the series hybrid, both of which use gasoline-electric hybrid technology, but in different ways.

Parallel hybrid cars use a gasoline engine and an electric motor together to move the car forward. In a series hybrid, the gasoline engine either directly powers an electric motor, or charges batteries that will power the motor. Both use regenerative braking to store the kinetic energy generated by brake use in the batteries, which powers the electric motor.

Both parallel and series hybrids have small gasoline engines but have much less power (about half) than average gasoline engines. The up side is that they produce much less pollution than standard gasoline cars, and are constructed with ultra lightweight materials like carbon fiber or aluminum. Hybrid car designs are more aerodynamic than most cars, allowing for less wind resistance. These factors combine to make a super efficient car that gets excellent fuel economy and helps the environment by cutting down on pollution.

There are other hybrids than electric-internal combustion, such as hydraulic and pneumatic hybrids, in which compressed fluids and compressed air are used for energy storage with regenerative braking.
