A system and method are provided for hybrid electric internal combustion engine applications in which a motor-generator, a switchable coupling and a torque transfer unit are arranged co-axially-arranged with the front end of the engine crankshaft in the constrained environment in front of an engine in applications such as commercial vehicles, off-road vehicles and stationary engine installations. The motor-generator is preferably laterally offset from the switchable coupling. The switchable coupling is an integrated unit in which a crankshaft vibration damper, an engine accessory drive pulley and a clutch overlap with an axial depth nearly the same as a conventional belt drive pulley and engine damper. The system includes an electrical energy store that receives energy generated by the motor-generator when the coupling is engaged. When the coupling is disengaged, the motor-generator may drive the pulley portion of the clutch-pulley-damper to drive engine accessories using energy returned from the energy store.
