Referred to as the 9HP, the nine-speed unit is extremely flexible, capable of being used in front- and all-wheel drive applications. The gearbox is also compatible with automatic start-stop systems and hybrid drivetrains.
The 9HP is capable of withstanding between 206 and 353 lb-ft of torque, making it ideal for four- and six-cylinder applications. ZF has yet to announce any OEM customers, but says the unit was designed for "customers in the USA and the Asian markets."ť
The nine-speed unit uses a standard torque converter, which ZF says aids in smooth starts and maneuverability. The gearbox has a total spread of 9.84, but shifting points and shifting dynamics can be customized by the end user.
No word on when we might see the new nine-speed unit on the road, but ZF may have just set the new industry benchmark.
