It was a complex hydropneumatic, computer-controlled active suspension system. This did away with conventional springs and anti-roll (stabiliser) bars in favour of hydraulic struts controlled by an array of sensors (such as yaw velocity sensors, vertical G sensors, height sensors, wheel speed sensors, longitudinal and lateral G sensors) that detected cornering, acceleration and braking forces. The system worked well and gave an unusually controlled yet smooth ride with no body roll. However, the additional weight and power requirements of the system affected straight-line performance somewhat.
Introduced in September 1989 on the Japanese market only Toyota Celica ST183 GT-R Active Sports.
