Cadillac’s fourth-gen MagneRide suspension is good to go in the 2021 CT5-V and CT4-V, and will also become available for the 2021 CT5 Sport and the all-new Escalade.

MagneRide 4.0 features a 45-percent faster damping response, which, according to Cadillac, makes it the world’s fastest reacting suspension technology. Changes include new accelerometers, better magnetic flux control and increased sensitivity to body motion.

“With MagneRide 4.0, the world’s fastest reacting suspension system is now even faster,” said Cadillac’s vehicle performance engineer, Thomas Schinderle. “When paired with our sedans’ award-winning rear-wheel-drive architecture, the result is two of the most responsive sport sedans on the market, with reflexes that elevate the already high threshold of the V-Series legacy.”

In its fourth iteration, MagneRide’s new wheel accelerometers are able to read the road up to 1,000 times per second, triggering changes in the magnetic charge within the magnetorheological fluid, which in turn alters the damping rates of the shocks “almost instantly”.

It’s four times faster than the previous system and can allow engineers to tune it for more pronounced differences between drive modes.

The 2021 CT4-V and CT5-V feature MagneRide 4.0 as standard and are priced from $45,890 and $48,790 respectively. In case of the 2021 CT5 Sport, it starts from $42,790 and MagneRide 4.0 is available as part of the new optional V Performance package, which also adds extra suspension performance upgrades and plus a mechanical limited-slip differential.

In the 2021 Escalade, MagneRide 4.0 is standard on the Sport and Platinum specs, which are priced from $86,890 and $101,290, respectively, and available with the optional Performance Package on the Premium Luxury trim.
