2005 4dr Wagon turbocharged 208hp 2.5L I5
5-speed shiftable automatic FWD		 Surprising fuel economy for the 2.5 turbo 208 hp engine. Several road trips with consistent 30 mpg at freeway speeds (70-75 mph).

The SS 2.4L is pretty quick and fun to drive and I still get 28 mpg on average just gunning around town with a lead foot and about 20% high see full Chevrolet Cobalt review
