HICAS
HICAS (High Capacity Actively Controlled Steering) is Nissan's rear wheel steering system found on cars ranging from the more recent Skyline and Fairlady Z (300ZX) iterations to smaller models like the Nissan Cefiro (A31), 240SX/Silvia (S13 & S15)/180SX and Nissan Serena/Nissan Largo. It is also found on models from Nissan's Infiniti division, such as the Q45, M45/M35 and G37. Unlike many other four wheel steering systems, HICAS and Super HICAS are fitted to improve handling rather than just as a parking aid.
