ZF 8HP Manufacturer ZF Friedrichshafen Production 2008– Predecessor ZF 6HP Class 8-speed longitudinal automatic transmission 
Automatic Transmission 8HP70
The ZF 8HP is an eight-speed automatic transmission, designed and built by ZF Friedrichshafen AG subsidiary ZF Getriebe GmbH in Saarbrücken.[1] It is to debut in a rear-wheel drive application in the new BMW 7 Series 760Li saloon fitted with the V12 engine.
One of its main aims is to improve vehicle fuel economy, and it can achieve an 11% saving compared to ZF-6 speed transmission and 14% verse modern 5-speed transmissions.[2][3] Due to changes in internal design, shift times have reduced to 200 milliseconds, along with the ability to shift in a non-sequential manner - going from 8th to 2nd in extreme situations.[4] In the 8HP70 version, it has a torque handling limit of 700 newton metres (516 ft·lbf), and weighs 90 kilograms (198 lb).[5]
Future development will see two four-wheel drive versions available, with version destined for Volkswagen Group applications, using a Torsen centre differential.[5] It will be able to encompass a torque range from 300 newton metres (221 ft·lbf) to 1,000 newton metres (738 ft·lbf), and will be available for use in middle class cars, through to large luxury sport utility vehicles.[5]
Chrysler Group LLC will initially receive the 8HP 8-speed automatic transmissions from the ZF Getriebe GmbH plant in Saarbrücken, Germany. By 2013, in parallel with Chrysler Group, ZF is setting up a new transmission production plant in North America, where the 8-speed transmissions will be produced.[6] ZF Friedrichshafen and Chrysler Group have reached a supply and license agreement for ZF's 8HP 8-speed automatic transmission. Chrysler Group is licensed to produce the 8HP at the company’s Kokomo Transmission Plant and the Kokomo Casting plant, starting in 2013.
