The BMW M4 is a high-performance version of the BMW 4 Series coupes and convertibles developed by BMW’s motorsport division, BMW M.
As part of the renumbering that splits the 3 Series coupé and convertible models from the 4 Series (to further differentiate it from the 3 Series), the M4 replaced the BMW M3 coupé and convertible models. Upgrades over the standard BMW 4-Series include an upgraded engine, suspension, brakes and weight reduction measures including increased use of carbon fibre, such as on the roof of the car.[1]
