Cadillac Unveils World's Fastest Active Suspension

The company has improved Magnetic Ride Control.

Cadillac has introduced the fourth-generation Magnetic Ride Control suspension. The company describes it as the most serious technology update since its debut on the Seville STS in 2002. It also calls it the fastest active suspension in the world. In comparison with its predecessor, a reaction speed is increased by 45 percent.

MagneRide 4.0, as in previous generations, uses shock absorbers with double electromagnetic coils built into the rod. They act on the magnetorheological fluid located in the working chamber, which can almost instantly change the viscosity level, clamping the suspension, in the presence of a magnetic field.

The optimal level of damping for each of the four pillars is determined using vertical acceleration sensors built into the hub: they work four times faster and “scan” the road up to a thousand times per second. The inertial measurement unit monitors the movement of the body relative to the wheel during sudden braking and cornering.

The control software of MagneRide 4.0 is also rewritten and the hardware is changed. Internal friction is reduced (the manufacturer says about the “zero damping” effect), and the difference between driving modes is made more obvious. In addition, secondary temperature maps are added to compensate for changes in the temperature of the liquid in the shock absorber for more stable operation, especially during dynamic driving.

MagneRide 4.0 will be included in the standard equipment of the new CT4-V (only for a rear-wheel drive sedan) and CT5-V. The CX5 Sport can be equipped with it for a surcharge as part of the V Performance package. The Escalade Sport and Platinum will also receive the adaptive racks.
