Disclosed are electrically variable transmissions (EVT), methods for making and for using EVTs, and hybrid electric vehicles with EVTs. Presented is a multi-speed power transmission for a motor vehicle with an engine, two electric motors, and a final drive. The transmission includes an input member connectable to the engine, an output member connectable to the final drive, and a stationary member connectable to a gear train. First and second torque-transmitting devices (TTD) respectively connect to the first and second motors. The transmission also includes a compound planetary gear arrangement with four junction points defined by two interconnected planetary gear sets. The first TTD selectively connects the first motor to the first junction point, while the second TTD selectively connects the second motor to the fourth junction point via the gear train. The input member connects at the second junction point, whereas the output member connects at the third junction point.
