During the 2011 Detroit Auto Show, ZF announced that is was forging forward with plans to develop a nine-speed automatic transmission and the gearbox specialist is now ready to dish out some details. ZF claims that the 9HP transmission has been designed exclusively for front-wheel-drive vehicles with transversely mounted engines. The tranny will reportedly be able to bolt into hybrid vehicles and is designed as a "construction kit," meaning that an additional transfer case could be added for all-wheel-drive. The 9HP is also stop-start capable.
More importantly, the 9HP was developed to assist automakers in boosting their vehicles' fuel economy ratings. ZF says that the transmission will cut fuel consumption by up to 16 percent versus vehicles equipped with six-speed autos. ZF claims that the fuel-saving tranny allows most engines to spin at 1,900 RPM, compared to 2,600 RPM in a typical six-speed-equipped automobile.
ZF has yet to release a rollout schedule detailing when the nine-speed transmission will make its first appearance in a production vehicle, but we're guessing it will be soon. Hit the jump to read all the details on ZF's 9HP trans.
