Land Rover presents the Evoque with a nine-speed automatic transmission from ZF at the 2013 Geneva Motor Show. While Land Rover calls it a concept, production for the transmission will begin soon in South Carolina, and it is only a matter of time until buyers can actually own this truck.
The ZF 9HP is the first nine-speed automatic transmission for a passenger car and is specifically designed for cars for transverse engine layouts. Jaguar Land Rover was among the leading partners in the transmission's development. In the Evoque, the 9HP weighs 7.5kg less than the current six-speed automatic.
In the Evoque, the 9HP adds three more gears to improve fuel economy, lower CO2 emissions and improve acceleration. The range of gear ratios starts lower than the six-speed in the Evoque and ends higher. That means that not only does the car actually improve its off-road and towing ability, but it cruises more quietly and more efficiently as well.
The transmission is designed to skip gears when up- or downshifting depending on throttle inputs. It gives the car that it is equipped in a boost in passing power by immediately dropping down to a lower gear.
The 9HP in the Evoque comes with multiple modes including Curve mode that keeps the engine from upshifting in the middle of a corner by monitoring lateral loads and Fast-Off mode that anticipates hard acceleration and keeps the vehicle in gear even when the driver is off-throttle.
