Year	Body/Powertrain	Comment
2007	2dr Hatch 255-horsepower 3.0L I6 6-speed manual RWD	it gets better fuel economy than the M coupe, but still out performs the 2.5i and 3.0i models. see full BMW Z4 review
2007	2dr Convertible 215-horsepower 3.0L I6 6-speed shiftable automatic RWD	Fuel economy is great. Getting 30 to 33 mpg on trips on 2 lane rural highways at 65 to 70 mph. see full BMW Z4 review
2006	2dr Convertible 215-horsepower 3.0L I6 6-speed manual RWD	Around town I get about 23 mpg but on the open highway, get 30 to 32 mpg which is huge since the Z only uses premium grade gas. see full BMW Z4 review
2004	2dr Convertible 225-horsepower 3.0L I6 6-speed manual RWD	Average 26-27mpg combined city/highway in daily commuter driving (no expressway)...even with some spirited driving. see full BMW Z4 review

Chevrolet Cobalt Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2010	2dr Coupe 155-horsepower 2.2L I4 4-speed automatic FWD	Around town it's not great, but out on the open road mileage almost doubles. see full Chevrolet Cobalt review
2009	2dr Coupe turbocharged 260hp 2.0L I4 5-speed manual FWD	The fuel economy is very good considering the performance available. I typically get better than 25MPG with a fair bit of city driving and fairly heavy throttle. see full Chevrolet Cobalt review
2009	4dr Sedan turbocharged 260hp 2.0L I4 5-speed manual FWD	In mixed driving I get 25 - 26 MPG, even with 75 mph stints and popping in and out of traffic. In pure highway, gets 28+ at 70+ see full Chevrolet Cobalt review
2008	4dr Sedan 148-horsepower 2.2L I4 4-speed automatic FWD	Better than most North American cars. Lower carbon footprint. Cheaper to run. see full Chevrolet Cobalt review
2007	2dr Coupe 173-horsepower 2.4L I4 5-speed manual FWD	Under good highway driving conditions the Cobalt can go 700km on a single tank, but even in harsh conditions fuel economy is reasonable. see full Chevrolet Cobalt review
2007	2dr Coupe 148-horsepower 2.2L I4 4-speed automatic FWD	Most neighbors report 35 mpg on hyway. here we do mostly high spped highway. see full Chevrolet Cobalt review
2007	2dr Coupe 173-horsepower 2.4L I4 4-speed automatic FWD	I like that the 2.4L engine is able to put out significantly more power than the 2.2L and keep the same economy. 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
2007	2dr Coupe 148-horsepower 2.2L I4 5-speed manual FWD	While not as impressive as some of its competitors, the Cobalt is still good for low to mid 30s if driven properly. see full Chevrolet Cobalt review
2007	2dr Coupe 148-horsepower 2.2L I4 4-speed automatic FWD	34 MPG observed - and this from a roomy stylish car that cost me less that 15,000 see full Chevrolet Cobalt review
2007	2dr Coupe 148-horsepower 2.2L I4 4-speed automatic FWD	While the Cobalt may only get 23mpg in real city driving with a heavy foot, it is still relatively easy to achieve 28mpg in the city and 35+mpg on freeway. see full Chevrolet Cobalt review

2010	4dr Sedan 155-horsepower 2.2L I4 4-speed automatic FWD	The best documented rating I could find when looking indicated it still did not rival Fiesta. see full Chevrolet Cobalt review
