Abstract

A powertrain is provided with a first input clutch and a second input clutch, each of which is selectively engageable to connect an engine with a transmission input member. Selective engagement of the first input clutch permits a motor to power the engine to start the engine. Selective engagement of the second input clutch permits the engine to power the transmission for propulsion.
