THE INTELLIGENT WAY TO POWER.
BMW’s xDrive system drives all the wheels, splitting the power 40:60 between front and rear, maintaining the rear drive bias for more enjoyable handling, but giving better grip in corners whenever conditions deteriorate, such as in rain or muddy conditions. It’s a simple idea, but to get the best from it, power needs to be able to vary between front and back axles, and between the left and right sides of the car.
An electronically-controlled gearbox and multi-plate clutch system allows BMW 4x4 models fitted with xDrive to vary the power between the front and back axles. If snow makes a wheel slip, xDrive reacts in a tenth of a second to redistribute power to the axle with the most grip.
