Groove, Beat and Trax

Besides the Groove, the Chevrolet concept trio includes the Beat (center) and the Trax (right). GM is hoping they'll appeal to young, urban car buyers. To get a better idea of the reaction to the rides, it wants potential buyers to vote online for their favorite at Vote4chevrolet.com.

The front-wheel-drive Beat--"built to be personalized," GM says--includes a navigation system and premium stereo. It has a 1.2-liter turbocharged gasoline engine. The all-wheel-drive Trax is a trails-traffic crossover concept powered by a 1-liter gas engine.
