The World’s Fastest Reacting Suspension Technology Gets Even Faster

The fourth generation of Magnetic Ride Control sharpens the driving performance of the Cadillac CT4-V, CT5-V, CT5 Sport and Escalade, with up to 45-percent faster damping response. The system is the world’s fastest reacting suspension technology, which allows for greater responsiveness and enhanced isolation from road imperfections.

The changes represent the most comprehensive updates since Cadillac introduced the suspension technology nearly 20 years ago on the 2002 Cadillac Seville STS. They include all-new wheel accelerometers, improved magnetic flux control and an inertial measurement unit that increases sensitivity to body motion, enabling even quicker changes as the suspension reads the road.

How it works

Magnetic Ride Control is an active damping system that uses electromagnets paired with magnetorheological fluid within the shock absorbers to continually vary their damping rate. Wheel accelerometers read the road up to 1,000 times per second, triggering changes in the magnetic charge within the fluid that can alter the damping rates of the shocks almost instantly.

By adjusting the damping rate, the car can better respond to varying road surfaces or sharp turns by maximizing tire contact on the road for greater driving precision.

What’s new

Debuting on the 2020 CT5-V and CT4-V, and expanding to the 2021 CT5 Sport and all-new Escalade, nearly every aspect of the previous system was reevaluated for the development of MagneRide 4.0. This includes the sensors, controller hardware, dampers and vehicle tuning methods.
