CES

Our CES system (Continuously Controlled Electronic Suspension) integrates the latest technology in hydraulics and electronics into a highly advanced suspension. The heart of the system is the CES valve, a hydraulic pressure controller specifically designed to fit the requirements for use in a suspension system. It combines a small size with a very wide working area and an extremely quick reaction time.

Use of the CES valve in a shock absorber removes most of the compromise between ride and handling found in conventional shocks. It enables the suspension to provide sportscar characteristics in cornering and lane changes while giving the ride of a limousine during cruising. We are now shipping the third generation of CES were the performance have been further refined compared to the previous generations.

Öhlins has been active in semi-active suspension development since the late eighties. We have built in-depth knowledge about the valves, shocks, sensors, ECUs and software required to make semi-active suspension work. With our knowledge we can not only supply the valves but also the support required to build a full system.

The CES valve is in mass production since 2002 and it is used by Mercedes, VW, Audi, Volvo and Ford.
Today there are more than 150.000 vehicles on the road equipped with CES. There are development projects running with several car manufacturers on cars to be launched in the next two years.

We have the capability to supply CES valves in numbers from a few hundred per year up to millions. The CES valve and our semiactive suspension support are today only available for OEM customers.
