The 575 hp (423 kW) 4.4-litre V8 M TwinPower Turbo engine of the BMW X6 M uses cross-bank exhaust manifolds, a pair of TwinScroll turbochargers, High Precision Direct Petrol Injection and VALVETRONIC – to push torque and output to higher levels still. This unrivalled combination ensures that a strong wave of torque is maintained from low revs and allows the engine to impress with its direct and rapid responses, vivacious appetite for revs, linear power delivery and customary M soundtrack. #MPowe
