BMW 2-Series Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
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
