A hybrid electro-mechanical transmission connectable with multiple power sources includes an output member and a stationary member. The transmission also includes a first planetary gear set having a first, second, and third node, and a compound planetary gear arrangement having a fourth, a fifth, a sixth, a seventh and an eighth node. The power sources include an engine, a first motor/generator and a second motor/generator. The engine and the first motor/generator are each operatively connected to the first planetary gear set. The second motor/generator is operatively connected to each of the first and the second planetary gear sets. The output member is operatively connected to the compound planetary gear set. Thus configured, the transmission provides under-drive, direct-drive, over-drive, and reverse gears for launching and propelling the vehicle.
