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, XT6, GMC Acadia recalled for two issues

General Motors is recalling three model years of the Cadillac XT5 and XT6, and the Cadillac's GMC sibling, the Acadia. The first recall has to do with the rearview camera. On 2020- and 2021-model-year XT5s, XT6s, and Acadias optioned with Surround Vision, insufficient crimping for the coaxial cables could cause a degraded signal from the rear camera, or cause the signal to fail. With all passenger vehicles required to have a working rearview camera, that's not an ideal situation. Only crossovers with Surround Vision are affected. The population at issue counts 95,231 vehicles, build dates being: XT5s produced from May 1, 2019 to June 23, 2021 XT6s built from February 25, 2019 to June 24, 2021 Acadias built from May 6, 2019 to June 24, 2021  The automaker hasn't been informed of any crashes or injuries related to the problem, and will begin mailing letters notifying owners of the issue on November 7. The fix is a trip to the dealer to have the cables inspected and replaced if necessary. Concerned customers can contact Cadillac customer service at 800-458-8006 or GMC customer service at 1-800-462-8782, then refer to GM's recall number, N222378380. Alternatively, they can get in touch with the National Highway Traffic Safety Administration (NHTSA) Safety Hotline at 888-327-4236 (TTY 800-424-9153), or go to www.nhtsa.gov, and refer to campaign number 22V709000. Another recall concerns just the 2023 Cadillac XT5 and XT6 and 2023 GMC Acadia units that were built on August 9, 2022. That day, a printer in the Spring Hill, Tennessee, Assembly Plant malfunctioned, producing vehicle labels for the driver's side B-pillar with illegible tire size information. That's a violation of a subsection of Federal Motor Vehicle Safety Standard No. 110. Only 24 units are affected, the fix being a jaunt to the dealer for a label with readable information. Owners who don't want to wait until November for letters from GM can contact Cadillac customer service at 800-458-8006 or GMC customer service at 800-462-8782, and mention recall number N222381690. Or they can head to the NHTSA Safety Hotline at 888-327-4236 (TTY 800-424-9153), or www.nhtsa.gov, and refer to campaign number 22V708000.

2020 Cadillac CT5 prototype shows off more lighting details

The elusive 2020 Cadillac CT5 luxury sports sedan has once again been spotted by a spy photographer. This time, we get to see it from all angles, whereas last time we only saw it from the front. It still has quite a bit of fake body work, and it's very clear Cadillac still hopes you'll think this is a Charger, from the big hood scoop to the fake full-width taillights. Digging past those misdirects, we can find some new details about the car. First, the car's front lighting has developed further. There are production-ready headlights fitted that appear to have some sort of LED illumination. These production lights also fit the shape we saw on the last prototype, so they'll end high up on the body, extending slightly horizontally toward the grille. There's still a section that extends back along the fender, seeming to bridge the gap between current Cadillacs and the Escala concept from which this car takes inspiration. Another addition are the vertical LED accent lights. This is another trademark feature of both current Cadillacs and the Escala, but they were absent from the last prototype we saw. We also get a look at some of the grille's details. Instead of slats, this CT5 has a plastic mesh of small rectangles. The pattern is reminiscent of brickwork. These photos also give us our first look at the back of the CT5. It looks like a fairly typical Cadillac. It's much more conservative than the front end. There are some angular cutouts in the bumper to allow exhaust gases out. The taillights have the current Cadillac look with the top curving over the rear fender. We can't tell if there will be a horizontal element like on the Escala, due to the fake lights. We're expecting the CT5 to be shown sometime next year in time for the 2020 model year. Odds are it will use off-the-shelf Cadillac engines including the turbocharged 2.0-liter four-cylinder, naturally aspirated 3.6-liter V6, and the twin-turbo 3.0-liter V6. Now that Cadillac has revealed its twin-turbo 4.2-liter V8, we'll be interested to see if that shows up in a future CT5-V.
