A visit to the EPA fuel economy site shows that, segment for segment, GM vehicles are competitive with any vehicles in the market.
GM currently has more models with EPA highway ratings of 30 mpg or better than any other carmaker, 18 in total.
We are not resting on our success. We are working to further improve the fuel economy of every new vehicle we build. For example, we recently announced plans for a new Chevy compact car, the Cruze, which is expected to have signficantly better fuel economy than the Cobalt, which is already among the most fuel efficient vehicles in its segment.
