This development may be started after the 1st generation power train's development had been finished and would still be largely concerned with internal combustion engines. This technology requires a more complex and longer development process which would incorporate knowledge and experience from previous developments. Its complexity also means that the first ones to implement it would gain a competitive advantage. The requirement will be that the applied machine parts should exhibit a near maximum efficiency in which case CO2 emission should be reduced by 20-30% while maintaining its original dynamic.
