The M TwinPower Turbo V8 petrol engine in the BMW X6 M.

Extreme driving pleasure requires first-class components. The key is to deliver huge amounts of power in just the right doses. Then there’s flexibility and endurance. First sprint, then keep the pace. Decelerate briefly, then sprint again. Again and again, right up to the limit. The powerful engine in the BMW X6 M was built to achieve exactly this, with M TwinPower Turbo technology from BMW EfficientDynamics, consisting of Valvetronic, High Precision Injection and innovative turbocharging.

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.

Fuel consumption is determined in accordance with the ECE driving cycle, made up of approximately one-third urban traffic and two-thirds extra-urban driving (based on the distance covered). CO2 emissions are measured in addition to fuel consumption. Further information on the official fuel consumption and on the official specific CO2 emissions of new automobiles can be found in the guidelines on fuel consumption and CO2 emissions of new automobiles (see The figures for fuel consumption and CO2 emissions apply in conjunction with the equipment selected.
Rated output: BMW recommends the use of super unleaded 95 RON fuel. Unleaded RON 91 fuel or higher with a maximum ethanol limit of 10 percent (E10) is also permitted. The performance and fuel consumption rates listed are based on the use of RON 98 fuel.
