Abstract
A powertrain includes an engine, a multi-speed transmission connected to a final drive, and a selectively engageable magnetorheological fluid clutch drivingly connected between the engine and multi-speed transmission. A motor/generator is operatively connected to the engine and the magnetorheological fluid clutch for selectively exchanging power with the engine and/or the magnetorheological fluid clutch such that the motor/generator may be used to start the engine, to drive the multi-speed transmission, and to receive energy from the magnetorheological fluid clutch for regenerative braking.
