Abstract
A multiple speed transmission for a motor vehicle includes an input member connected to an electric motor, an output member, four planetary gear assemblies, each with first, second, and third members, and a plurality of torque transmitting devices, such as, brakes and clutches. The electric motor can be employed for regenerative braking. Further, the electric motor can be employed to launch and drive the motor vehicle with each of the gear ratios of the multi-speed transmission.
