Wolfgang Hatz, 53, has until recently had dual roles, being both Porsche's board member for R&D, and head of Powertrain Development at the Volkswagen Group. Effective 1 October, responsibility for VW Group Powertrain shifted to Heinz-Jakob Neußer, allowing Dr Hatz to fully concentrate on his role at Porsche. He recently spoke to Glenn Brooks about future models, platforms and engines.
