A drive unit for a hybrid electric motor vehicle includes an engine, an electric machine including a rotor, a layshaft gearset including an input driveably connected to the engine and an output, for transmitting power between the input and the output and producing a first speed differential that causes a speed of the input to exceed a speed of the output, first and second driveshafts, a differential mechanism driveably connected to the output, for transmitting power between the output and the driveshafts, and a planetary gear unit driveably connected to the output and the rotor, for transmitting power between the rotor and the output and producing a second speed differential that causes a speed of the rotor to exceed the speed of the output.
