HYBRIDS

Hybrids utilize two different power sources to propel the vehicle. Currently, that means gasoline engines and electric motors. Utilizing two power sources allows hybrid vehicles to obtain improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.

Unique among hybrids is the Chevrolet Volt. Electric motors power the wheels and the gasoline is only used to extend the driving range of the vehicle.

Some of the advanced technologies typically used by hybrids include the following:

Electric Motor Drive/Assist. The electric motor provides additional power to assist the engine in accelerating, passing, or hill climbing. This allows a smaller, more efficient engine to be used. In some vehicles, the motor alone provides power for low-speed driving conditions where internal combustion engines are least efficient.

Regenerative Braking. The electric motor applies resistance to the drivetrain causing the wheels to slow down. In return, the energy from the wheels turns the motor, which functions as a generator, converting energy normally wasted during coasting and braking into electricity, which is stored in a battery until needed by the electric motor.

Automatic Start/Shutoff. Automatically shuts off the engine when the vehicle comes to a stop and restarts it when the accelerator is pressed. This prevents wasted energy from idling.

Below is a list of Hybrid Vehicles that you'll be able to see at the 2010 Chicago Auto Show.
