The hybrid system is to be supplied by a collaboration of Bosch, Williams Advanced Engineering and Xtrac. Bosch will provide the (40kW) motor-generator unit, which will attach to the front face of the Xtrac transmission, within the bell housing (which will be unique to each engine installation). At the same time, the battery system and control electronics, from Williams, will install from underneath the chassis. These cars will be fitted with manufacturer-designed bodywork and branded internal combustion engines (be they bespoke racing units or production car sourced). For the first time in more than 20 years, it will be possible for a car brand to fight for overall victories with identical vehicles at endurance races around the world.

‘In the medium term, Porsche focuses on three different drive concepts: fully electric vehicles, efficient plug-in hybrids and combustion engines,’ says Michael Steiner, Board Member for Research and Development at Porsche AG. ‘We want to represent this trilogy in both the development of our cutting-edge road cars and in motorsport. We use the all-electric drive to contest the FIA Formula E as part of our works commitment, and a highly efficient combustion unit in GT racing. Now, the LMDh class closes the gap for us.
