Future CO2 scenarios raise the need for a systematic view on the best fitting solution for the whole drivetrain. A wide range of different technical solutions are available to suit the individual demands. Out of this large variety, short-termed this may be a direct injected downsized turbocharged gasoline engine as one of the most promising solutions to be applied in large volume production. On the other extreme there may be an electric powertrain, considered to be more long-termed. For both approaches and for all solutions in between there are challenges which have to be overcome. This paper deals with specific challenges of named two powertrain applications and describes the technical solutions for it: - For the gasoline direct injected engine (GDI) the forthcoming EURO 6 emission standards, especially with respect to particulate number PN emissions, is considered to be a challenge. - For electric vehicles the limited operation range due to battery weight and cost is a hard trade-off which has to be matched. So called Range Extender RE units with combustion engines may be a solution for this. By systematical evaluation of potential solutions and by means of appropriate development tools and methodology the challenges for development of future leading powertrain can be overcome.
