The fuel economy window sticker from our new car (and another at right). The explanation for this sticker doesn't tell you much except that the EPA figures the average driver drives 15,000 miles/year. What I don't understand is why this car would be classified as a “subcompact.” If you look at the list of subcompacts, you'll see they're basically all sporty coupes. Class sizes are apparently determined according to interior volume, so from this I'm guessing that the EPA is talking about the coupe. (Is it possible that the coupe and the sedan have the same interior room? I can't see how....) Compare that to the list compacts; the compacts (the Honda Civic, Toyota Corolla, VW Jetta, Dodge Neon, etc.) look much more similar to our Cobalt. In a side-by-side comparison, the Cobalt does pretty well against the Civic and the Corolla, although it's not surprising to see that the American make is bigger in all external dimensions and smaller in all internal dimensions. Why must that be?
