A drive train for a hybrid vehicle having first, second and third motors includes a first variable transmission, having an input shaft, and an output shaft coupled to a drive wheel of the vehicle, and first, second, and third clutched rotational drive connections. The rotational drive connections selectively interconnect an output shaft of the first, second and third motors, respectively, with the input shaft of the first transmission, whereby torque from each of the three motors can be selectively combined through the variable transmission to drive the drive wheel.
