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 XT5 platform to underpin three-row crossover

Cadillac just launched the XT5 crossover to replace the SRX. But that's only the start. Speaking with Automotive News, Caddy president Johan de Nysschen confirmed that a new three-row crossover is also on the way. The seven-seater is based on a stretched version of the flexible platform underpinning the XT5, which we just drove recently. Taking that approach will give the luxury brand a larger crossover to pit against the likes of the Infiniti QX60, Audi Q7, and Volvo XC90 without having to develop one from scratch. It will also give buyers a more car-like alternative to the larger, truck-based Escalade. "It's one of the benefits of having this very flexible architecture. We can expand it, make it longer and wider. That gives us the ability to develop the car very quickly, as opposed to starting from scratch," de Nysschen told AN. "It's not running yet. It is a program request that we initiated with the engineers only last year. They are working at remarkable, record-breaking speed to get us the car." The new model would likely be called the XT7 and offer similar levels of equipment to the existing, smaller XT5. The existing mid-size model packs a 3.6-liter V6 mated to an eight-speed automatic transmission and comes in four trim levels. Related Video:

2015 Chevy Silverado, GMC Sierra recalled for steering issues

DETROIT — General Motors Co is recalling more than 1 million pickup trucks and sport utility vehicles in the United States due to issues with a temporary loss of power steering, the National Highway Traffic Safety Administration said. The recall is for 2015 models. They are: the Chevy Silverado 1500, Suburban and Tahoe, GMC Sierra 1500, Yukon and Yukon XL and Cadillac Escalade. The problem may cause difficulty steering the vehicle, especially at low speeds, increasing the risk of a crash, the auto safety regulator said in a document dated Sept. 12. The document did not highlight any reports of accidents and injuries, because of the power steering issue. GM dealers will update the power steering module software, free of charge for owners of the affected vehicles. In 2014, the No.1 U.S. automaker had recalled nearly 800,000 pickup trucks worldwide because of the same problem. GM did not immediately respond to a request for comment.Related Video:
