So im building a rally car out of a 2005 cobalt base. I'd like to make it awd. To make a rear wheel drive addition to the vehicle i want to try to fabricate an electric motor to the underside. The mechanical aspect is the easy part for me, however i know absolutely nothing about electric motors, speed controllers and batterys. My goal is to have enough torque to provide just a little support for the front wheels which are powered by the engine (145hp / 155lbft) a 70% front 30% rear ratio would be ideal but not necessary, as only a tiny support is what im looking for. If i can power only the rear wheels enough to get the 2,700lb car going at least 20kmh it would work. Does anyone know what type of motor could accomplish this? And what batterys and management system would have to go with it.
