The BMW Z4 M Coupé is a sports car for very special moments – moments the driver may well experience every kilometre, every mile on the road. Uncompromising, purist, and extremely powerful, this two-seater offers an unparalleled experience of undiluted dynamism both in everyday traffic and on the race track. Without doubt, its prize-winning 3.2-litre straight-six M power unit developing maximum output of 252 kW/343 hp offers performance of the highest conceivable standard.
