When Magnetic Selective Ride Control came out on the '03 Corvette it was apparent that GM had finally perfected a more active system that actually incorporated PCM-adjusted damping rates, similar to Active Suspension, using the same inputs and sensors. Except unlike the C4's hydraulic system, the C5's F55 suspension used a more powerful PCM and "Magneto-Rheological" fluid contained in traditional shock absorbers. The synthetic oil permeates millions of tiny iron balls, which changes viscosity based upon the electric current that feeds it. The desired goal, though, was the same-a flatter ride and more responsive handling. As we near the seventh generation Corvette, we can only wonder what the latest evolution of this technology holds for us.

 Hydraulic fluid is diverted...  Hydraulic fluid is diverted to all four corners via computer controls from the pump according to speed, steering, load, wheel position, and other sensors to react to the road much more effectively than traditional shocks and springs. |  Special air scoops in the...  Special air scoops in the front fascia were needed to divert air onto the hydraulic oil coolers, and vents on the fenders also help cool the hydraulic system. Packaging the hydraulic system was one of the tightest and most difficult ever on one of GM's cars. |  Active Suspension is the father...  Active Suspension is the father of Active Handling that was introduced on early C5s, and grandfather of Magnetic Selective Ride Control, which was first available on the '03 C5 and is currently available on the C6. Though it never made it to production, the information gained during the creation and testing of Active Suspension was obviously invaluable for future innovations. |
