Super-HICAS stands for "Super High Capacity Actively Controlled Steering." It is a technology used in some vehicles to enhance maneuverability and stability. By adjusting the rear wheels' angle in response to the driver's steering input, Super-HICAS improves cornering performance and helps the vehicle maintain better control during high-speed driving. This system typically operates at low speeds to assist with tight turns and at higher speeds to provide stability. Nissan is one of the manufacturers known for implementing Super-HICAS in their vehicles, particularly in performance models like the Nissan 300ZX and Nissan Skyline.
