There are several options in maximum torque available, also the gearbox is available with mild hybrid and plug in hybrid options: With 15 kW and 200 NM supporting boosting and recuperation in combination with 48 Volt technology up to 90 kW and 250 NM for usage with higher voltage. Major improvements are total spread of 8.6 and a fuel economy improvement of 2.5% compared to the 2nd generation. Refinements were also made with respect to vibration.ģrd generation 8HP products were released starting in 2018. ZF estimated fuel economy improvement over 1st generation 8HP kits to be 3%. Efficiency improvements over the original design include a wider ratio spread of 7.8:1, reduced drag torque from the shift elements, reduction in required oil pump pressure, and broadened use of the coasting and start-stop systems. Ģnd generation 8HP products were released starting in 2014. This transmission is marketed by Chrysler under their own brand name, the Torqueflite 8. Chrysler Group is licensed to produce the 8HP at the company's Kokomo Transmission Plant and the Kokomo Casting plant, production began in 2013. ZF Friedrichshafen and Chrysler Group have reached a supply and licence agreement for the 8HP. By 2017, in parallel with Chrysler Group, ZF had set up a new transmission production plant in Gray Court, South Carolina. Ĭhrysler Group LLC initially received the 8HP from the ZF plant in Saarbrücken. It will be able to encompass a torque range from 300 N⋅m (220 lbf⋅ft) to 1,000 N⋅m (740 lbf⋅ft), and will be available for use in middle-class cars through to large luxury sport utility vehicles.
įuture development will see two four-wheel drive versions available, with a version destined for Volkswagen Group applications using a Torsen centre differential. In the 8HP70 version, it has a torque handling limit of 700 N⋅m (520 lbf⋅ft), and weighs 87 kg (192 lb). Due to changes in internal design, the shift times have reduced to 200 milliseconds additionally, the unit brings the ability to shift in a non-sequential manner – going from gear 8 to gear 2 in extreme situations.
One of its main aims is to improve vehicle fuel economy, and it can achieve 12% saving compared to the ZF 6HP transmission and 14% versus modern 5-speed transmissions.

It had its debut in the BMW 7 Series (F01) 760Li saloon fitted with the V12 engine, and since then each new BMW model in all Series down to the 1 Series in rear-wheel-drive and all-wheel-drive versions have had the option to be equipped with it. 8HP (8-speed transmission with hydraulic converter and planetary gearsets) is ZF Friedrichshafen AG's trademark name for its 8-speed automatic transmission models for longitudinal engine applications, designed and built by ZF's subsidiary in Saarbrücken, Germany.
