Toyota Active Control Suspension

Toyota Active Control Suspension was (according to Toyota) the world's first fully active suspension.[1]

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.[2] 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.

Ten years later, Mercedes-Benz introduced a very similar active suspension, called Active Body Control , on the Mercedes-Benz CL-Class in 1999.
