Part electric car, part hybrid, the BYD F3DM (pictured) is a Chinese car expected to go on sale in the U.S. next year. The hybrid car is equipped with a battery pack and two electric motors. BYD calls it a dual mode -- the DM part of the F3DM name. BYD engineered the car to drive mostly on electricity. As long as the batteries' charge level is above 20 percent, the two motors handle all the work; approximately 30 miles down the road, the car automatically switches from electric to hybrid mode.

General Motors' first "green" Buick, the 2012 Regal eAssist, will be available this fall. Mated to the Regal's 2.4-liter four-cylinder engine and six-speed automatic transmission, the eAssist system uses power stored in an on-board battery pack to provide an electric-motor boost. Regal's eAssist technology also features regenerative braking, improved underbody aerodynamics and low-rolling-resistance tires. It is expected to get 26 mpg in the city and 37 on the highway.
