Most likely to support the regenerative breaking system, the Supra HV-R used a capsitor based regenerative braking system. And in a hybrid system an electric motor fills both roles of motor/generator. Not to mention 13 hp is a bit deceptive for an electric motor because the torque grows massive the lower the RPM, so I'm sure it provides a significant boost coming out of low speed corners. For example, the Prius Electric motor produces only 44hp but generates 258lb./ft. from 0-400rpmte72;1895858 said:Makes me wonder though, 13hp electrical motors in each front wheel? If not for moving the car in the pits, then what were those for? Post race margaritas? :dunno:
