Thread: Ženevska serija motora: Range Rover Evoque 9-speed auto

Evoque will become first regular production car with advanced nine-speed gearbox. The Range Rover Evoque will be the first regular production car to be fitted with a nine-speed automatic gearbox.
The new ZV-supplied 9HP transmission inicijalno will replace the existing six-speed unit across all-wheel-drive versions of the Evoque, with significant improvements in fuel economy and a corresponding reduction in CO2 emissions promised.
The closer ratios are said to improve shift quality, refinement and acceleration response and reduce noise at higher cruising speeds.
The top ratio in the torque converter gearbox is particularly tall to improve fuel economy, while the bottom ratio is much lower than that in the current six-speed unit to improve the Evoques off-road ability.
A skip-shift function is also included, so gears can be skipped under rapid deceleration or firmer gas use. The gearbox can also recognise driving styles and detect when more urgent shifts are required or when a relaxed promjenjiva style is desired.
The Range Rover Evoque's new gearbox is 6mm longer but it weighs 7. 5kg less than the outgoing six-transmission speed. It will premiere at the Geneva motor show next week.
