Abstract
A hybrid electric vehicle powertrain has an engine and a motor at the torque input side of a power transmission. The motor has a single stator and dual rotors. A selectively engageable rotor clutch connects the rotors together for torque delivery during a driving mode. During a key start and a rolling start of the engine, the rotor clutches are selectively engaged and released.
