June 14, 2007 Driveline and Chassis Technology company ZF invests five percent of its sales (2006: EUR 600 million of EUR 11.7 billion) in Research and Development and in so doing, has developed a very interesting new Torque Vectoring rear axle drive which it claims considerably increases driving dynamics and safety reserves of all-wheel drive and rear-wheel drive vehicles. The system distributes the drive torque individually to the rear axle wheels, generating a yaw moment around the vertical axis of the vehicle, which can be used both to improve agility and stabilize the vehicle. Generation of the wheel differential torque is independent from the drive torque, so it is also generated during coasting, when the driver is not accelerating. The system is ready for volume production and is already planned for volume application at BMW.
