Just curious, so Ithought I'd share this: I chose base engines with auto, for comparison purposes.
Model hwy/city/overall
Focus: 32/26/28 Cobalt: 32/24/27 Civic: 40/30/34 Corolla: 38/30/33 Mazda 3: 34/26/29 Caliber: No Entry??
All figures from the EPA.
In short, the new cobalt is slightly worse than the old-design focus. The '3' has a reputation as having pretty poor gas mileage, but in fact is better than the domestic brands. However, the honda and toyota are amazing. if you're in the market for a small car, and can afford the premium for an import, AND gas mileage is one of your top concerns....there's really only 2 choices.
Interesting. JP
