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.

Johan de Nysschen tells his side of the story

Automobile snagged time with ex-Cadillac, Infiniti, and Volkswagen of America boss Johan de Nysschen. General Motors decided to part ways with de Nysschen on April 18, 2018, after the German spent four years in charge of America's luxury brand. The longtime auto exec is a polarizing figure for enthusiasts, who seem to take a mostly negative view of his work at Infiniti and Cadillac. However, there's no denying de Nysschen is frank, and in the Automobile interview he puts an insider's perspective on a big bag of issues we can only speculate on. One of the biggest bombshells in the interview was that it wasn't de Nysschen's idea to move Cadillac to New York: "When I was recruited, I was informed that the company would relocate to New York," he said. Previous GM CEO Dan Ackerson had made the decision before hiring de Nysschen, then Ackerson let his new hire make the announcement. The big change came only two years after de Nysschen had taken over Infiniti after insisting Nissan's luxury brand move to Hong Kong. De Nysschen explained Cadillac's NYC move with the same rationale as Infiniti's Hong Kong move, so everyone assumed the new guy was doing his usual. He explains in the interview that after the move, "Folks who rooted for Detroit felt betrayed. Cadillac had an enemy." And that became a problem. He has nothing bad to say about GM or Cadillac, believing on the contrary that "GM is in a good position going forward." But he brought clarity to some of Cadillac's struggles. Among the issues was GM's "very vigorous" post-bankruptcy test for green-lighting a project. Another was the lack of specialization for the luxury arm. "Engines were generically developed with the Chevy brand in mind," he said, "and, then, 'Okay, well, yeah, it's good enough for Cadillac.'" That carried over into haphazard technology rollouts. "GM didn't have a specific technology roadmap aligned to particular brands," he said. "The process was, as they were developing new technologies, they would look at what product's launch date would be aligned with the maturation date and market readiness of a technology and go with it, whether Buick, Chevy, or what have you." De Nysschen worked to end such generalized approaches, which is how we get Cadillac taking the GM lead on technology and electrification.

2015 Cadillac ATS, CTS recalled over brake issue

A problem with the brakes on the 2015 ATS and CTS has prompted Cadillac to issue a recall. According to the notice below from the National Highway Traffic Safety Administration, the issue revolves around the bracket that connects the brake pedal assembly and the rod that actuates the brakes. Even under normal operation, that bracket could fracture, impeding the ability to slow or stop the vehicle. That, as you're surely aware, could increase the risk of a crash. The issue affects a reported 2,163 vehicles in the United States. Owners will need to be bring their vehicles in to their local dealership to have those brackets replaced starting on August 1. See the complete recall notice below. RECALL Subject : Brake Pedal Bracket may Fracture Report Receipt Date: JUN 09, 2015 NHTSA Campaign Number: 15V358000 Component(s): SERVICE BRAKES, HYDRAULIC Potential Number of Units Affected: 2,163 Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2015 Cadillac ATS and CTS vehicles. The affected vehicles have a bracket between the brake pedal assembly and the rod that actuates the brakes that may fracture during normal brake pedal operation. CONSEQUENCE: If the bracket fractures, the driver would not be able to apply the brakes, increasing the risk of a crash. REMEDY: GM will notify owners, and dealers will inspect the vehicle and replace any affected bracket, free of charge. The recall is expected to begin August 1, 2015. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 15352. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
