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

smart fortwo Real Gas Mileage: Pros
YearBody/PowertrainComment
2013 2dr Hatch 70-horsepower 1.0L I3
5-speed automated manual RWD		 good mpg car for the price and simplicity of a lightweight car with only a gas engine. Even if you only get the EPA combined estimate of 36 it is good mpg and competes well in its class. But many smart drivers get much higher. My first 10k miles averaged 45 mpg, based on miles per gallon measured at each fill up, mix of city and freeway. Recently I had 48 mpg and 51 mpg tanks on my usual route. Check Fuelly.com for a realistic picture of mpg to expect. Low 40s mpg is most common. see full smart fortwo review
