The tremendous rate of increase of individual mobility demands is a huge challenge for the automotive industry. The severe increase in the consumption of fossil energy sources as well as the growing greenhouse gas emissions require alternative, innovative and economical powertrain solutions in the discussion of resource and climate policy. The partly electrification of the powertrain in motor vehicles due to hybridisation seems to be the suitable answer at present. Currently the hybrid technology is seen as the bridge to the complete electrification of the powertrain. Due to the deployment of hydrogen, fuel cells are predicted as the long-term energy converter. The design of the powertrain concepts for electrical and hybrid-electrical applications shows similarities. Here the combination of engine and transmission plays an important role.
