BMW’s New M Sport Package Pro on The New 4-Series Coupe Previews Next-Gen M4

The new package is in addition to all the M bits that come on the standard M Sport model. The Pro gets the eight-speed Steptronic Sport transmission with the Sprint function, available in Sport mode, that allows for short bursts of speed and more pronounced engine sounds in the cabin. It also includes M Sport brakes, M seatbelts, and a Harman Kardon sound system that the new Z4 got.
