An electric powertrain includes a speed reducer and an electric motor housed in contiguous casings, together with an air cooling circuit for the speed reducer and the electric motor. The cooling circuit includes an opening for the inlet of air into the casing of the speed reducer, openings for the passage of air in a casing wall separating the speed reducer from the electric motor, and an air outlet opening in the casing of the electric motor. The cooling circuit also includes a fan placed at a height relative to the speed reducer and the electric motor, an upstream conduit that channels the air from the fan toward the speed reducer, and a downstream conduit for the outlet of the air from the electric motor toward the ground.
