ZF working with GKN on new VectorDrive system

Torque vectoring systems, devices that transfer drive between individual wheels for improved traction, largely remain the stuff of premium AWD models and high-performance sports cars but that may change soon thanks to OEM suppliers like ZF and GKN. The two companies are now working on new rear-axle system dubbed VectorDrive, designed for both RWD and AWD models.

GKN will supply the electric motors, electronic control units and programming modules for VectorDrive and ZF will assemble and deliver the final system to customers, reports Automotive News.

When driving in a straight line, the torque vectoring rear axle acts like an ordinary transmission with an open differential, with drive being distributed equally among both sides of the drive-shaft. The torque is only distributed individually to either wheel during cornering, where it’s controlled by an electromechanically actuated multi-disk brake of the superimposed axle drive.

One of the first companies listed to receive VectorDrive is BMW but there’s no word on which models it’s expected to debut on. ZF is also developing a new eight-speed automatic transmission for the German premium label.
