The Cobalt is Chevrolet's family of compact coupes and sedans, and it returns for 2009 with only minimal changes.Thanks to a taller drive ratio and variable valve timing, the EPA estimates that the 2009 Chevrolet Cobalt will get 37 mpg on the highway and a respectable 25 mpg in the city. The Cobalt is quiet and refined for a small car and it delivers crisp handling and a smooth ride, all benefits of its strong, rigid platform. Cobalt earned Best Pick status from the Insurance Institute for Highway Safety.
