The task of maximising traction, agility and handling stability in the new BMW X7 again falls to the latest generation of the BMW xDrive intelligent allwheel-drive system, which now varies how the drive torque is split between the front and rear wheels with greater precision than ever for the situation at hand. The electronically controlled all-wheel-drive system links up with Dynamic Stability Control (DSC) to provide the basis for effortless, sure-footed handling, whatever the road and weather conditions. For added efficiency, full drive power can be directed to the rear wheels in situations where all-wheel drive is surplus to requirements. The xDrive system also maintains a rearbiased set-up when the car’s dynamic performance abilities are being put to the test, ensuring customers enjoy the signature BMW driving experience.
An M Sport differential is fitted as standard on the BMW X7 M50d and in conjunction with the Off-Road package on the BMW X7 xDrive50i, to complement the powertrain’s sporting characteristics. This electronically controlled rear differential lock also hooks up with the DSC system. It works by limiting the equalisation of the rotational speeds of the wheels on the inside and the outside of the bend and thus optimises the transfer of power to the road in dynamic driving situations. As a result, any tendency to understeer when powering through corners can be countered effectively. The M Sport differential deliberately shifts drive power – which cannot be transferred to the road by the unloaded wheel on the inside of the bend, as it is likely to slip – to the wheel on the outside of the bend (instead of applying to brakes to neutralise its effect). The locking effect – produced by an electric motor – draws the BMW X7 into the bend with infectious élan. The increase in power finding its way onto the road also makes a notable difference when exiting corners, as the optimised distribution of power allows the car to accelerate out of the bend again with particular verve. By preventing a wheel from spinning when it is struggling for purchase, the M Sport differential also improves traction and power transfer on loose ground or road surfaces offering differing levels of grip for the left and right rear wheels.
