A drive module for a vehicle including an electric machine, an inverter, a gearing assembly, and a cooling system. A first housing member thermally coupled with the inverter has a first set of heat exchange surfaces and a second housing member thermally coupled with the electric machine has a second set of heat exchange surfaces. The first and second sets of heat exchange surfaces each project into an interior volume cooled by an externally supplied liquid coolant which thereby defines a heat exchanger. A lower oil sump for collecting oil used to cool the electric machine may also include heat exchange surfaces projecting into the same heat exchanger. The gearbox may include an elevated oil sump which is supplied by the same oil pump circulating oil on the electric machine wherein the elevated oil sump gravity feeds oil onto selected surfaces within the gearbox.
