My 2005 Chevy Cobalt has a 13.1 gallon tank.
The Cobalt replaced the cavalier, a compact. The Aveo, is a sub-compact, and has better numbers.

The Chevy Cobalt Coupe will hold five passengers. The backseats of this car are not easily accessible but it does have a large trunk. The gas mileage of the Chevy Cobalt Coupe is a great selling point.
A new Chevy cobalt are very nice cars. But, they are extremely expensive. They are aroundd 30 thousand dollars and they aren't that good on gas. My friend owns one, and says they aren't as they advertised it. I suggest you do not get a Chevy cobalt!
