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.

Steve Carlisle replaces Johan de Nysschen as head of Cadillac

Johan de Nysschen, a longtime automotive industry executive, is out the door at Cadillac after four years at the helm of GM's flagship luxury brand. Steve Carlisle will replace de Nysschen as General Motors senior vice president and president, Cadillac. Carlisle previously served as president and managing director of GM Canada. Travis Hester will replace Carlisle in that role, starting immediately. "We appreciate Johan's efforts over the last four years in setting a stronger foundation for Cadillac," said General Motors President Dan Ammann. That strong foundation is mostly seen overseas. Cadillac has seen record sales in China under de Nysschen's watch, but has continued to flounder in its home market of the United States with market share significantly lower than rival brands like Audi, BMW, Lexus, and Mercedes-Benz. Growth in the U.S. market is mostly happening with crossovers and SUVs, and Cadillac has been trailing its German and Japanese rivals on that front. The brand-new XT4 is seen as a big potential sales booster for the automaker, but its late arrival has already hurt the brand's sales figures here in America. "Looking forward, the world is changing rapidly, and, beginning with the launch of the new XT4, it is paramount that we capitalize immediately on the opportunities that arise from this rate of change," said Ammann. "This move will further accelerate our efforts in that regard." Carlisle will report directly to Ammann in his role as the head of the Cadillac brand. Related Video:

2015 Cadillac Escalade

Cadillac has been an interesting story in the auto industry over the past several years. Its comeback bid may be well over a decade old, but it's only recently that the Wreath and Crest has transformed from the auto industry's retirement home into its hot new thing. Today's Cadillac is a powerful marque working to instill passionate design, sound driving dynamics and cutting-edge technology into each model it builds, with vehicles like the ATS and redesigned CTS leading the charge.
Now, its latest model has arrived. This fourth-generation Escalade is among the most important new Cadillacs since the division's renaissance kicked into high gear. It's the brand's de facto flagship, and the first vehicle many young people think of when hearing the name "Cadillac." In the past, the Escalade was the chosen vehicle of the rich, flashy and famous. It's suffered over the past few years, though, particularly as new and more luxurious competitors have come to the fore.
With this latest redesign, General Motors is aiming to retake the spotlight as purveyors of the market's premier luxury SUV. To find out if it's been successful, I ventured down to the South Carolina Lowcountry to test the all-new 2015 Escalade.
