2014 Infiniti Q50 Hybrid Review

System architecture of the RWD one-motor 2-clutch hybrid system. Clutch 1 (a dry single-plate clutch) is installed between the engine and the electric motor. This clutch allows the full decoupling of the V6 when the systems is in either electric or power regeneration modes, thereby reducing mechanical drag and boosting the efficiency of the electric motor. Clutch 2 (a wet multi-plate clutch) transmits the drive force. This was the best compromise Nissan opted for after modeling several series-parallel (power split) and parallel architectures.
