The future powertrain mix will be derived above all from a CO2- and emission-optimized vehicle fleet. The results of a powertrain variation study show that a scenario with high HEV share in the fleet is robust in regard to the external boundary conditions, particularly the electricity mix and the share of renewables. The high share of combustion engines also makes it easy to reduce CO2 emissions using synthetic fuels. A low share of PHEV, BEV and FCV also results in reduced manufacturing costs on the powertrain level. Furthermore, the analysis which powertrain mix would be expedient for WtW-CO2-legislation. Finally, modular powertrain systems were allocated to various vehicle segments to allow for a combination of combustion engines with dedicated hybrid transmissions with one or two electric motors and various electric axle configurations from single-speed to seamless-shifting multi-speed transmissions.
