BMW 2-Series Real Gas Mileage: Pros

2014 2dr Coupe turbocharged 320hp 3.0L I6
8-speed shiftable automatic RWD
The #3 pro of this hardcore sports car, surprisingly, is fuel economy. All the major brands are taking surprising lengths to be eco-friendly. In 'Eco' mode, the 300 horsepower M235i can manage a surprising 22/33 mpg. There is a MPG bar constantly running below your speedometer, constantly challenging you to try to make it as big as possible. The car also features regenerative braking to power the car's electrical systems. see full BMW 2-Series review

It is better than I expected. I average roughly 23 miles with city and highway commuting on days I choose to take it to the office. On trips I can get 26 mpg, not stellar but not awful. see full Porsche Cayman review

Fuel economy is reasonable relative to the car's performance - 20 mpg, plus or minus a couple depending on the balance of city versus highway driving. see full Porsche Cayman review
