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 Design shows what could have been and what might be

We periodically like to check in with GM Design's Instagram account to see what they're cooking up. Even better is when we catch a glimpse of an alternate history of what legendary designers from The General's past were thinking, though those ideas may not have made it into production. This week, for example, the account posted some illustrations from George Camp, whose career at GM spanned nearly four decades, from 1963 to 2001. One of the renderings is of what appears to be a 1971-72 Pontiac GTO Judge, but with two headlights instead of the production unit's quad beams. The rear departs from the canonical version most dramatically, with a massive integrated wing. Other bits that didn't make the production cut include large side vents, a gill-like side marker and rectangular intakes below the headlights that wouldn't be out of place on a modern design today. Amazingly, from what we can make out of the date, it appears that the drawing was done sometime in 1965, which makes it quite prescient.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) There's also a very aerodynamic interpretation of a Corvette ZR-1. To our eyes it splits the difference between the 1986 Corvette Indy concept and a fourth-generation F-body Pontiac Firebird, so perhaps parts of Camp's work on this sketch did make it into physical form. There's also a radical sports car concept from May 1970 that resembles the Mazda RX-500 concept from the same year, a Syd Mead-looking Cadillac coupe, and an Oldsmobile with a cool take on the company's trademark waterfall grille and elements of the Colonnade Cutlass at the rear. Other recent posts include a FJ Cruiser-like off-road EV, a sleek coupe with the Chevy corporate grille, and a rendering of a Silverado-esque pickup that looks far better than the current production version.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) It's pretty easy to lose hours in the account, but it's always fascinating to see GM's visions of what could have been and what might be.

[UPDATE] Cadillac Blackwing gets ticket to Italy, to go to work in a supercar

UPDATE: It seems MAT's belief it had secured a supply of Cadillac's 4.2-liter Blackwing V8 was premature, and based on a handshake deal before GM sold its Turin engine center to Italy's Punch Group. Shortly after Hagerty ran the story, GM sent a statement to the outlet reading, in part, "We do not have an agreement in place with Manifattura Automobili Torino (MAT) to provide or sell the Blackwing engine. ... Our team is following up with MAT president Paolo Garella to discuss the misunderstanding." MAT also submitted a statement to Hagerty, saying, in part, "We thank GM for the clarification. Although a signed agreement was not finalized between the parties, we were under the impression that our counterpart was committing to making this engine available to MAT at conditions yet to be defined. ... We hope that this misunderstanding will not compromise our relations with GM and possible future collaborations." The original article follows: Some necessary cost-cutting at Cadillac led to switching the new CT4, CT5, and Escalade to older platforms. The revised architecture plan meant Cadillac's newest top-tier products couldn't fit Cadillac's newest top-tier engine, the 4.2-liter twin-turbo DOHC V8 known as Blackwing. That engine would serve limited duty at full power in the now-dead CT6-V, and at reduced output in the CT6 Platinum V8 trim before ending its bright, brief domestic life. But the story isn't over, the rebirth of Blackwing coming from a most surprising locale: Turin, Italy. Before the canceled Geneva Motor Show, Hagerty spoke to Paolo Garella, CEO of Manifattura Automobili Torino; that's the company better known as MAT, makers of the New Stratos and contract engineering house for boutique screamers like the Aspark Owl electric hypercar, Apollo Intensa Emozione, and SCG003C. Garella told the outlet, "We have an agreement with General Motors" for a supply of Blackwings, which would be developed and built at the General Motors Propulsion Engineering Center (PEC) in Turin. Since 2005, the PEC has been used to develop GM's global diesel engines and electronics. MAT's plan is to put the V8 into a new limited-run car MAT is creating from its own design. Then another surprising turn: Belgium-based global auto supplier Punch Group bought the PEC, with plans to work with GM on projects in progress until at least the end of 2021. Nothing changes as far as MAT is concerned, except perhaps a chance for an even closer collaboration with Punch Turin.
