Two types of alternative-powetrain vehicles.(NEWS)(Brief article)

Automotive News' Hybrid Guide explains the powertrains of the future hybrids, electrics and others as well as the fuels each uses. Here is a sampling.

1. Electric

A battery pack powers an electric motor that drives the wheels. The battery pack must be plugged in to be recharged. An electric vehicle has no onboard capability to recharge the battery pack. Automakers sometimes refer to such electric vehicles as "pure electric" or "battery electric."

2. Hybrid

According to the Society of Automotive Engineers, a hybrid vehicle uses two energy sources stored onboard for propulsion, such as gasoline in the tank and electricity in the battery pack.
