2014 Range Rover Evoque 9-speed Auto

Land Rover demonstrates the world's first nine-speed automatic transmission for passenger cars at the 2013 Geneva Motor Show. The ZF 9HP Transmission is designed for cross-applications and is one of the most efficient and technologically advanced transmissions ever in a production model. Land Rover is the lead partner in this project with ZF. Increasing the number of gear steps 6-9 will help to improve emissions and efficiency. Smaller ratio steps give a better answer if the acceleration, with improved shift quality and sophistication. A higher top gear improves efficiency by reducing the speed boost comfort and reduces noise while driving on the highway.

The 9HP is fairly robust and complements the off-road capability of a Land Rover vehicle to be expected, while an exceptionally high performance and efficiency. The lowest rate was in the 9HP is lower than the existing six-speed gearbox and is for off-road use, developed towing and road conditions such as steep slopes. While the existing six-speed transmission allows downshifting sequentially 9HP has a skip-shift function for much faster switchover to emergency braking requirements. When the driver requires a downshift instructing when the vehicle is traveling too fast to the selected gear, the transmission of the request, and storing the offset, when the speed to an appropriate level. "Fast-off" mode measures the speed of the gas release provides further requests the driver for high performance, keep the gear, if necessary.

The torque converter with a multi-stage damping system for a smoother and provided improved pull configuration. An innovative adaptive shift fits the mood of the driver within seconds, great during the grinding disk and then seamlessly switches to an economic program if you ride at a relaxed approach. In addition, "Curve" mode detected acceleration / deceleration forces and the position of the pedal all control upshift timing. The 9HP is expertly packed and despite the additional three courses is only 0.24 inches (6 mm) longer and actually weighs 16.5 pounds (7.5 kg) less than the previous six-speed transmission. The compact packaging achieved by using a number of innovative design features: Replace a new compact hydraulic vane pump, two patented jaw couplings bulky conventional clutch plates and a nested programs.

Land Rover and ZF current partners in transmission development, together fully integrated solutions for data transfer in the Range Rover, Land Rover LR4 and Range Rover Sport have developed. The new nine-speed transmission is produced in Gray Court ZF plant in South Carolina, USA.
