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, Pilot will build EVgo fast chargers at 500 truck stops across U.S.

All of our maps showing electric vehicle charging stations across the U.S. are going to need an update. Today, General Motors, Pilot and EVgo announced plans to work together on a nationwide DC fast charging network. The plan calls for 2,000 charging stalls that can deliver up to 350 kW to be installed at up to 500 Pilot and Flying J travel centers in the U.S. The goal is to have DC fast chargers available in 50-mile intervals across the country. The new charging stations will feature GM's "Ultium Charge 360" branding and "Pilot Flying J" logos but will not be limited to drivers of GM EVs. The plugs will use CCS connectors and be available to anyone. GM EV owners can take advantage of benefits, including the ability to make exclusive reservations, get discounts on charging costs and streamline the charging process with Plug and Charge and in-vehicle apps that can provide real-time charger availability. The first installation phase will take place in 2023, and "the bulk of the installations" should be completed by 2025, EVgo CEO Kathy Zoi said during a conference call with reporters announcing the plan. "We're gonna get going immediately and commence all of that engineering and planning stuff," she said. "We've got a pretty orderly plan." Pilot CEO Shameek Konar said the company expects the new EV charging stations to coexist with the current fuel infrastructure. "An average Pilot Flying J location is about 10 acres," Konar said. "This will be in addition to all of our gas pumps. The way I think about it is, this is a new source of energy that is going to coexist with gas for quite some time. We can debate how long, but we need to serve both groups of customers." Installing DC fast chargers at hundreds of Pilot's travel centers — aka truck stops — means there should be food, drinks, restrooms, WiFi and even showers available while you wait for an EV to charge. Pilot recently announced its “New Horizons” plan that will invest $1 billion in upgrading Pilot travel centers with more premium amenities, including expanded seating and lounge areas. While the exact amount of time it will take to charge an EV using these new stations will vary on the EV and its current state of charge, most EVs can refill from a low state of charge to around 80 percent in 20-30 minutes on a fast charger. The new stations are future-proofed to deliver up to 350 kW, a charge rate that few EVs today can handle.

GM follows Ford and Honda in skipping SEMA

The list of automakers skipping SEMA has become longer. First reported by Muscle Cars and Trucks, and confirmed to us by a company representative, General Motors will not have an official presence at the aftermarket show. It joins Ford and Honda in leaving the show. It will be a large hole in the show, with the GM brands typically filling a significant swath of available show space in one of the main halls. GM hasn't provided much explanation for the move, either. The GM representative provided Autoblog with the same statement that Muscle Cars and Trucks got: "GM has made the decision not to participate in the 2022 SEMA Show. The SEMA show has always inspired us, and accessories and performance parts remain an important part of our business." We also asked if we would see any sort of announcements around the time of the show — Ford said it has plans to share some things around that time — however, the GM representative said that the company has no immediate plans for announcements. Certainly things could change between now and the November show, though. SEMA had previously noted that other exhibitors would help fill in some of the space vacated by these major OEMs. Another OEM, Volkswagen, is returning to the show after an absence, which will also help with the display deficit.
