Here's how Cadillac made its Magnetic Ride Control suspension quicker and smarter

Bugatti makes the world's fastest car, but Cadillac claims it has developed the world's fastest suspension. Its fourth-generation Magnetic Ride Control technology receives hardware and software tweaks to deliver a more comfortable ride and sharper handling. It's offered on some variants of the CT4, CT5 and the Escalade. Introduced in 2002 on the Seville STS, this self-adjusting suspension is not as complicated as it might sound. It relies primarily on electromagnets that emit a magnetic field, and a magnetorheological fluid whose viscosity changes depending on the strength of the magnetic force. Sensors scan the road up to 1,000 times per second and send the information they gather to the electromagnets, which then alter their magnetic field as needed to modify the fluid's viscosity. The fluid is in the shocks, so making it thicker returns a firmer ride, and vice versa. In simpler terms, Magnetic Ride Control leverages chemistry and physics to make the ride sporty, comfortable, or somewhere in between -- all in the blink of an eye. By reacting to the changing magnetic field, the fluid-filled shocks filter out road imperfections and maximize tire contact with the road to deliver more precise handling. Cadillac began developing the fourth-generation system by improving the hardware. The in-wheel accelerometers are more accurate than before, the inertial measurement unit is more precise, and the damper fluid formula was changed for quicker response times and a smoother ride. Engineers then turned their attention to the system's software. They notably gave the sensors the ability to process a wider selection of input and output signals, which translates to a wider spread between comfort and sport. And, they made the response time up to 45-percent quicker. All told, the fourth-generation Magnetic Ride Control technology performs better under heavy braking and hard cornering, it delivers more consistent performance, and it reads the road more accurately. Cadillac proudly notes these are the most comprehensive updates it has made to the system in nearly two decades. Magnetic Ride Control comes standard on the 2021 CT4-V and the 2021 CT5-V, and it's bundled into the CT5's V Performance package, which also includes a mechanical limited-slip differential. It's also standard on the Sport and Platinum variants of the 2021 Escalade, and it's part of the Premium Luxury trim's Performance package.

Cadillac confirms CT8/CT9 flagship, ELR successor

Cadillac has certainly been a hot topic as of late, what with Johan de Nysschen now running the joint, moving its headquarters to New York, and overhauling the company's naming structure (only to later publicly defend all of these drastic decisions). Now, looking ahead, de Nysschen is already revealing some details about what's in store for the future, including a raft of new products that include a large, long-wheelbase Mercedes-Benz S-Class rival positioned above the recently announced CT6, along with a successor to the slow-selling ELR coupe.
In an interview with Reuters, de Nysschen says his company has "just signed off on" a new flagship tipped to be called CT8 or CT9. It will compete with the long-wheelbase versions of the Mercedes-Benz S-Class and BMW 7 Series, and should come to market by the end of this decade.
Among other news, the South African executive said a followup to the ELR plug-in hybrid is in development, though it may not be a two-door coupe like the current car. That's not necessarily a bad thing, since the ELR has garnered nothing but slow sales and poor reviews since its launch.

Cadillac SRX and Saab 9-4X recalled for suspension defect

General Motors has recalled 380,498 vehicles due to rear suspension toe link adjusters that may not have been tightened properly, which could result in a loose toe link. The vehicles affected by the recall are Cadillac SRX crossovers built between 2010 and 2016, and Saab 9-4X crossovers built in 2011 and 2012. A loose toe link could cause instability while driving, especially at highway speeds. This recall follows up an investigation by the National Highway Traffic Safety Administration after it received complaints from SRX drivers of uncontrolled swaying while driving. According to the agency, two incidents led to a crash. It's possible that improper procedures for tightening a toe link nut during four-wheel alignments may have resulted in corrosion and thread wear on the adjustable portion of the link. Owners of affected vehicles are advised to park their crossovers if they experience certain Malfunction Indicator Lamp warnings on the dashboard or if they feel unusual steering behavior while driving. According to the official NHTSA recall notice, dealers will replace the adjustable toe link with a non-adjustable one at no charge. Letters are expected to be mailed to owners of affected vehicles on August 9, 2021. Alternatively, owners can call Cadillac customer service at 1-800-458-8006 or Saab customer service at 1-800-955-9007 and reference recall number N212340980. This is the second time many of these vehicles have been recalled for problems with the rear toe links. Back in September of 2014, GM announced that it would recall 290,241 vehicles that included SRX and 9-4X models because a "nut in the rear suspension toe adjuster link may not be torqued to the proper specification."
