Don't get me wrong but I don't believe an 80 kg system can work with batteries able to run the car over liaisons. In my opinion such low weight suggests that the system would rather use supercapacitors or flywheels to give reasonable boost on acceleration over short period of time.
Besides the power boost on the stages, the hybrid system is also required to be used in electric mode inside urban areas on the liaisons.
