Compact, low to the ground, and frugal, the F30 chassis 3 series betters the E90 in pretty much all aspects (except for handling, I guess). Fitted with the 2L staple BMW diesel motor, the N47 and the newly launched (back then) ZF8HP gearbox, the car has a great torque spread all over.Great sedan for people who are looking for a fuel efficient and peppy car.
