Claim:
1. A powertrain for a vehicle, the powertrain comprising: an engine including a crankshaft being rotatable about a longitudinal axis; a ring gear attached to a first distal end of the crankshaft such that the ring gear and the crankshaft are rotatable in unison about the longitudinal axis; a motor-generator including a motor/generator shaft being rotatable about a first axis, with the first axis being spaced from the longitudinal axis; and a starter mechanism including a first starter gear coupleable to the motor/generator shaft, wherein the first starter gear is rotatable about a second axis, with the second axis being spaced from the longitudinal axis, and with the first starter gear being movable along the second axis between a first position engaging the ring gear such that torque is transferred from the motor-generator to the starter mechanism via the motor/generator shaft, and a second position disengaged from the ring gear to rotatably disconnect the starter mechanism from the ring gear, wherein the motor/generator shaft transfers torque through the first starter gear and the ring gear to the crankshaft to start the engine when the first starter gear is in the first position.
