An apparatus includes an electro-mechanical transmission including a transmission output shaft and first and second transmission input shafts selectively coupleable for rotation with a first torque generative device. A planetary gear set including first, second and third members and a reduction gear set selectively coupling the first transmission input shaft for rotation with the first member and selectively coupling the second transmission input shaft for rotation with the third member. A first gear set input shaft is selectively coupled for rotation with the first transmission input shaft and coupled for rotation with the reduction gear set. A second gear set input shaft is selectively coupleable for rotation with the second transmission input shaft and coupled for rotation with the reduction gear set. A second torque generative device is coupleable for rotation with one of the first and second gear set input shafts.
