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.

GM says safety is a reason it's dropping Apple CarPlay, Android Auto

Update: GM sent us a statement as a follow-up to its original comments seen in this post: "We wanted to reach out to clarify that comments about GM's position on phone projection were misrepresented in previous articles and to reinforce our valued partnerships with Apple and Google and each company’s commitment to driver safety. GM's embedded infotainment strategy is driven by the benefits of having a system that allows for greater integration with the larger GM ecosystem and vehicles." The original story can be read in its entirety below.   General Motors announced its intention to remove Apple CarPlay and Android Auto functionality from its upcoming EVs earlier this year, and internet comments sections haven't been kind since. As the first of many EVs to follow – the 2024 Chevrolet Blazer EV – hits the market, GM is expanding on its initial explanations for dropping the tech. Motor Trend spoke with Tim Babbit, GMÂ’s head of product for infotainment, to learn more. Attributed to Babbit, from the story: “They have stability issues that manifest themselves as bad connections, poor rendering, slow responses, and dropped connections. And when CarPlay and Android Auto have issues, drivers pick up their phones again, taking their eyes off the road and totally defeating the purpose of these phone-mirroring programs. Solving those issues can sometimes be beyond the control of the automaker.” Babbit suggests that a world without Apple CarPlay or Android Auto will be a safer one, as folks wonÂ’t be looking to control their infotainment systems via their phones. However, Babbit also tells MT that this theory hasnÂ’t been tested in either the lab or the real world yet. Instead of using a navigation or music-playing app powered through your phone, upcoming GM EVs will use a Google-based infotainment system called “Ultifi” that runs a ton of integrated Google apps. Google Maps will be the native navigation app in the system; youÂ’ll be able to log in to Spotify or other apps to load your music up, and so on. The idea here is that youÂ’ll have all the same apps that were on your phone available but integrated within the infotainment system instead, and you'll be able to use voice controls to control every last bit of it with no need to reach for a phone. That sounds amenable in theory, but how consumers react to the removal of a feature that they know and love now is a risky gamble.

Junkyard Gem: 1969 Cadillac Coupe DeVille

The Cadillac Division was riding high in 1969, with sales numbers far surpassing those of Lincoln and Imperial. A few more years remained before fuel prices would go crazy, and prosperous Americans knew that a sleek DeVille or Eldorado gave them bragging rights at the country club. Here's a thoroughly used-up '69 Coupe DeVille, finally at the end of its journey and residing in a self-service wrecking yard in Denver, Colo. This inspection certificate shows that the car lived in Louisiana a decade ago. Since this is the sort of pervasive rust that occurs in places much wetter than arid High Plains Colorado, we can assume that this DeVille spent many years in the land of gumbo and alligators. The decklid sports Fleetwood badging and a Rickenbaugh Cadillac emblem, but Cadillac didn't make two-door Fleetwoods in 1969. Perhaps a Colorado-sold Fleetwood donated its decklid to replace a rust-ravaged lid on this car. Actually, there's a good chance it was purchased at this very yard. The once-opulent interior has suffered greatly over the decades, with the reek of mildewed carpeting and irradiated leather giving it That Hooptie Car Smell. Try to picture what this scene looked like in happier days, a half-century ago. The 1969 Cadillac V8 engine displaced a mighty 472 cubic inches (that's 7.8 liters to those of you living under the cruel knout of the metric system) and delivered a gross 375 horsepower and 525 lb-ft of torque. Scaling in at 4,595 pounds (about a half-ton less than a new Escalade), the DeVille needed that power to keep up with those cheap-but-V8-equipped Chevy Chevelles. For 1970, Cadillac would stroke this engine to a staggering 500 cubic inches for Eldorado buyers. This engine family lasted through 1984, after which it was replaced by the much-loathed High Technology V8. The build quality and snob appeal of the 1969 Cadillacs kept them on the road for decades after most of their peers got crushed, but this one was just too far gone to be worth restoring.
