ZF 8-Speed Automatic Transmission
ZF has developed a new automatic transmission for cars with eight speeds that can achieve more than 6% fuel savings. The priority aim in development, however, was not the maximum number of gears, but minimum consumption.
ZF engineers had set the bar high to produce a new benchmark for automatic car transmissions. The second generation of the ZF 6HP 6-speed transmission, that entered production only in 2006, defines standards that are hard to top: reaction times faster than human perception, direct engine linkage by early-stage torque converter lock-up and intelligent, adaptive control software, that almost reads the driver's intentions from his foot.
But the new transmission is capable of even more - it saves (even more) fuel. It also guarantees ultimate driving enjoyment, as well as the variability needed to be able to use future technologies.
