But does it make the ride uber-soft like a Cadillac? I wouldn't say that.
You might not want to say that about a Cadillac suspension because they're using the most advanced shocks in the world (heck, even Ferrari buys them from GM):
Magneto-rheological shocks, or MR shocks for short, have been one of GM’s most publicized technologies for over a decade. On paper, it allows manufacturers to access a wider range of suspension setup possibilities that non-adjusting shocks may not accommodate. In the real world, MR shock performance has been well-documented: good handling and good ride quality typically coexist. The 2003 C5 Corvette was the first Chevy to offer the tech (standard on the 50th Anniversary Edition). The C7 Stingray continues the trend, with the Z51 Performance Package opening up the additional third-generation Magnetic Ride Control option. Unannounced C7 high-performance models will presumably utilize MagneRide too.
Some readers understand how the MagneRide damping works. The monotube shocks are filled with a special magneto-rheological fluid formulated by Lord Corporation. The gist of the mission brief is the MR fluid, which is dosed with iron particles, can be magnetized at different strengths by way of electromagnetic coils (one coil per shock on previous gens, two on current). The neat trick is the coils can vary the fluid thickness many times per second, so an MR shock is capable of adjusting for road surfaces and driver demands than a run-of-the-mill twin-tube shock. Raising the thickness effectively increases the oil’s viscosity; this in turn affects damping force.
Most car buffs are aware MagneRide made its first appearance on a midyear refresh of the 2002 Cadillac Seville STS. From there, the MR dampers migrated onto a few other Cadillacs; perhaps most notably, it’s featured on all three body styles of the CTS-V. Audi, Ferrari, and the Camaro ZL1 have recognized the benefit too.
