Please visit us at - br ZF has developed a new automatic transmission for cars with eight speeds that can achieve 11 fuel savings. The priority aim in development, however, was not the maximum number of gears, but minimum consumption.br br 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.
