ZF technology for driving dynamics and comfort
Faster, more comfortable, safer
Driving should be an enjoyable experience. But what people enjoy can be very subjective. Depending on the driver and mood, the thrill of going fast may be enjoyable on some days, and a leisurely cruise through the city on others. Driving dynamics and comfort are flip sides of the same coin. ZF driveline and chassis products tap the full potential.
Intelligent shifting
For drivers, forward motion is a question of elapsed time – and human perception. With ZF transmissions like the second-generation 6-speed automatic and dual-clutch transmission, shifting is so quick, that it can hardly be perceived by passengers in the vehicle. The fast bridging of the torque converter ensures a more direct response. Intelligent shift electronics adapt instantly to the relevant driving style and practically read the driver’s intentions from the sole of his foot, for fast acceleration in the passing lane, or comfortable cruising around town.
Preserving power
Efficient, more dynamic acceleration requires the transfer of engine torque to the drive wheels and pavement without power loss through transmission slip or wheel spin. The ZF Torque Vectoring System and Vector Drive® rear drive unit deliver added performance by precisely distributing torque to where it is needed in all driving situations.
Electronic networking
The electronic networking of all vehicle drive units including the automatic transmission, transfer case, front and rear drive units makes it possible to distribute drive torque between the front and rear axles as well as between the left and right drive wheels. This supports steering movements and stabilizes the vehicle. On all-wheel drive vehicles, the driver can sense this optimal torque distribution when steering into tight curves or quickly changing lanes – even when he takes his foot off the accelerator. Rear-wheel drive vehicles can also benefit from this intelligent distribution of drive torque.
Unbridled dynamics
ZF redefined the limits of driving dynamics. In other words, depending on the driver, it is possible to drive with a sportier style or with more safety reserves. ZF engineers are working on the next-generation of controlled suspension systems. They are adapting components into the entire networked environment of the automobile, including the brakes and engine. This is especially important for the IWD (Intelligent Wheel Dynamics) system. In the IWD concept, a central control network intervenes as required when the vehicle reaches its dynamic limits in the active steering, the electronic CDC (Continuous Damping Control) system, and the Vector Drive rear drive unit to take corrective action and stabilize the vehicle in critical situations.
