BMW xDrive is the marketing name for the all-wheel drive system found on various BMW models since 2003.[1] The system uses an electronically actuated clutch-pack differential to vary the torque between the front and rear axles. Models with the DPC torque vectoring system also have a planetary gearset to overdrive an axle or rear wheel as required.
Prior to the introduction of xDrive, all-wheel drive was available on several models since 1985, based on an all-wheel drive system that uses viscous couplings.
