M TwinPower Turbo V8 petrol engine.
Two high-rev TwinScroll turbochargers. Tested on racetracks, with a cooling system comprising four circuits and ten radiators to keep thermal stress under control. A cross-bank exhaust manifold for perfect exhaust gas flow, optimum power development and lightning-quick responsiveness. With its massive torque of up to 750 Nm, the 4.4 litre, 575 hp M TwinPower Turbo V8 petrol engine powers the BMW X6 M forward with the minimum effort, accelerating the vehicle from 0 to 62 mph in just 4.2 seconds. Despite this top performance, fuel consumption and CO2 emissions remain moderate: Thanks to a wide range of BMW EfficientDynamics technologies, the combined values are 11.1 l/100 km and 258 g/km respectively.
