Chronology
PredecessorZF 6HP transmission

The ZF 8HP transmission is ZF Friedrichshafen AG's trademark name for its 8-speed automatic transmission models for longitudinal engine applications. The name is short for 8-speed transmission with hydraulic converter and planetary gearsets. Designed and first built by ZF's subsidiary in Saarbrücken, Germany, it debuted in 2008 on the BMW 7 Series (F01) 760Li saloon fitted with the V12 engine. BMW remains a major customer for the transmission.

Another major customer is Stellantis, who both received a license to produce the transmission and set up a joint-venture plant with ZF. Stellantis has built the transmission at its Kokomo Transmission plant since 2013 under their own brand name, the Torqueflite 8.[1][2] The joint venture plant in Gray Court, South Carolina opened in 2017.[3]

Specifications

Design

One of the main aims of the ZF 8HP transmission is to improve vehicle fuel economy with extra speeds. Compared to the six-speed ZF 6HP transmission it uses 12% less fuel, and 14% less than a 5-speed transmission.[4][5] 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.[6] In the 8HP70 version, it has a torque handling limit of 700 N⋅m (520 lbf⋅ft), and weighs 87 kg (192 lb).[7]

First generation 8HP products were released starting in 2010. In addition to the rear-wheel drive variant, two different four-wheel drive versions were available, with a version destined for Volkswagen Group applications using a Torsen centre differential.[8] It is able to encompass a torque range from 300 N⋅m (220 lbf⋅ft) to 1,000 N⋅m (740 lbf⋅ft), and is available for use in middle-class cars through to large luxury sport utility vehicles.[8]

Second generation 8HP products were released starting in 2014. Efficiency improvements over the original design and the first generation 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.[9] ZF estimated fuel economy improvement over first generation 8HP kits to be 3%. Refinements were also made with respect to vibration.

Third generation 8HP products were released starting in 2018. Major improvements are total spread of 8.6 and a fuel economy improvement of 2.5% compared to the second generation. 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.[10]
