Dynamic Stability Control allows the driver to choose from three modes: DSC on, MDM (M Dynamic Mode), DSC off. While DSC on counteracts understeer and oversteer to great effect with selective brake activation and torque reductions, MDM allows greater wheel slip – to give keen drivers the chance to execute some mild drifts. However, the driver aids will also intervene to assist the driver in this mode if a predefined limit is exceeded. Deactivating DSC (through DSC off) gives the driver the chance to fully explore the vehicle’s limits on the track and nudge the vehicle into power oversteer (i.e. a drift) using the accelerator. In this mode, the system will only intervene in extreme situations involving significant shifts in lateral acceleration. The new M TwinPower Turbo engine. A V8 with even more torque, backed by an emotionally rich soundtrack. To say the newly developed engine of the new X5 M and new X6 M has a pounding heartbeat would be something of an understatement. After all, the 4.4-liter V8 uses innovative M TwinPower Turbo technology – consisting of cross-bank exhaust manifolds, a pair of TwinScroll turbochargers, High Precision Direct 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 direct and rapid responses, linear power delivery and customary M soundtrack. Maximum performance meets outstanding efficiency. The peak output of the new M turbocharged engine powering the X5 M and X6 M is, at 567 hp, three percent higher than that of its predecessor and is available between 6,000 and 6,500 rpm. At the same time, the engine’s peak torque has been boosted by around 10 percent to 553 lb-ft, which can be enjoyed across an extremely broad rev band – from 2,200 to 5,000 rpm. The extraordinary power development of this M turbocharged engine allows the new M versions of the BMW X5 and BMW X6 to sprint from 0 to 60 mph in a mere 4.0 seconds. The top speed of both is electronically limited to 155 mph. The outstanding efficiency of the new M TwinPower Turbo engine is illustrated by its 20 per
