AUBURN HILLS, Mich.--()--GKN Drivelines high performance Torque Vectoring technology has made its world debut on the new BMW X6 sports activity coupe.

GKN Drivelines new technology is at the heart of BMWs Dynamic Performance Control (DPC) system which is being pioneered on the new, highly-acclaimed 4x4 vehicle. The company also supplies the latest front and rear side-shafts for the X6.

GKN Driveline has jointly developed Torque Vectoring technology with ZF. In this first production application for BMW, GKNs Torque Vectoring hardware units are shipped to system leader ZF, which is responsible for the final assembly and supply of the Vector-Drive rear-axle system.

The BMW X6s dynamic performance and stability control systems, of which GKN Drivelines Torque Vectoring products are active components, overcome the tendency of 4x4s to understeer when cornering under power at speed. BMW engineers developed integrated chassis management control software to manage all the disparate systems to produce an overall package that redefines the dynamic performance, safety and all-terrain ability of powerful SUVs such as the X6.

The challenge for premium car manufacturers is to provide greater sophistication in driving dynamics while reducing weight and cost, said Graeme Walford, managing director of GKN Driveline Torque Technology. With our latest driveline technologies in torque vectoring and sideshafts, GKN Driveline has been able to help BMW achieve a remarkable first with the X6.

GKN Drivelines Torque Vectoring hardware units are based on a modular, cost-effective approach that is designed to be easily adaptable to a range of vehicles. Two units per axle provide the requested vectoring torque by a super-imposition planetary gear set electronically controlled at the ZF system level by an electric motor actuated clutch.

GKN Drivelines actuator hardware consists of a wet clutch and a two-stage ball ramp mechanism to achieve the accuracy within the required response time. The gears of the planetary gear set are only active when needed to increase fuel efficiency. The wet clutch is designed for high-thermal capacity and very low drag torque. Various unique features, including the design of the gears and the ball ramp, have been introduced and patented by GKN Driveline.

The new Torque Vectoring technology is specifically targeted at rear-axle application on premium rear-wheel drive and all-wheel drive passenger cars and SUVs and further strengthens GKN Drivelines product range in this segment, which includes an electronically controlled limited slip differential (ETM®), electronic locking differential and a range of passive limited slip differentials.
