Unveiled in 2009, the BMW X6 M E71 established the high-performance sports activity coupé genre, combining the dramatic sloping roofline of the X6 with BMW M's first-ever turbocharged all-wheel-drive powertrain. Capable of embarrassing dedicated sports cars in a straight line while defying physics in the bends, it made an indelible impression. Operating this exotic heavyweight on British roads requires dedicated BMW X6 M maintenance, treating its running gear with high-performance discipline.
Under the power-bulged bonnet sits the 4.4-litre S63 twin-turbo V8 featuring crossover exhaust manifolds in the hot-vee, generating 555 hp and 680 Nm. Power is directed via a reinforced six-speed M automatic gearbox and rear-biased M xDrive with Dynamic Performance Control torque-vectoring rear differential. The extreme heat concentrated in the hot-vee engine valley places extraordinary demands on the quad-radiator cooling system and turbo oil supply lines.
