Compared to previous magnetic ride control systems developed initially in 1995, Magnetic Ride 4.0 is a revolution and completely changes how the Corvette utilizes the adaptive suspension technology.
Two changes that happened with 4.0 is they went away from position sensors at each corner that calculate roll and pitch, to an accelerometer on the knuckle at each corner. You get immediate feedback as soon as the knuckle starts to move. An accelerometer measures changes in velocity along one axis. This gives more accuracy and more exact control for the suspension calibration with a lot more precision.
Another upgrade to the precision with the MR 4.0 is the addition of an IMU or Inertial Motion Unit that measures the exact heave, roll and pitch signals versus calculated ones. These better signals allow for better tuning of the suspension. All this happens within the MR controller.
Magnetic Ride Control unlike other fixed solutions deliver incredible control at high speeds and cornering forces. All of the rebound and compression ratios through all of the velocity ranges are all tunable and that is where you get the rolling plushness that really stands out in the FE2 and FE4 suspensions regardless if you have the Z51 or not.
Benefits:
- No mechanical wear and tear
- Accurate and precise in assessing road conditions and using the magnetic power to vary the viscosity of fluid
- Low-velocity damping control on small bumps, dips or rollers
- Similarly, high-velocity damping control can assist on tough terrains
- Determines the force required at a certain velocity to adjust the fluid viscosity and draw the force-velocity graph
Apart from these benefits, the Magnetic Ride Control system detects the driving and road conditions 1000 times each second. That said, this suspension system can adjust in milliseconds and provide a better ride quality than the normal suspension system.
Sid, these are some of my notes from the launch of the C8 and the vehicle dynamic engineers comments. Still priced the same as it was when launched in 2020, in 2023 40.7% of C8 owners selected Magnetic Ride Control and it is included in every Z06 built for a reason.
