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.

2017 North American Car, Truck, and Utility of the Year entries announced

Over 40 vehicles will compete for the 2017 North American Car, Truck, and Utility of the Year awards. If that name looks a little strange, it's because the competition added a third category. In years past, pickup trucks, crossovers, SUVs, commercial vans, and minivans competed for the same award. That's why there were occasionally weird comparisons, like last year's competition between the Volvo XC90 and Nissan Titan XD. The new format separates pickups and commercial vans into the truck contest and CUVs, SUVs, and minivans into the utility competition. A complete list of eligible vehicles is below, but here are a few highlights. For one, the entire list of entries has a luxurious lean. Of the 43 vehicles, nearly half of them are from premium brands. There are two eligible Bentleys – the Bentayga and Mulsanne – the Rolls-Royce Dawn, Jaguar F-Pace, Audi Q7, and the Mercedes-Benz GLS-, E-, and S-Class Maybach. The performance ranks are lofty, too, with the Audi R8, Acura NSX, Alfa Romeo Giulia, Mercedes SL- and SLC-Class, Porsche 718, and F-150 Raptor. The mainstream entries are just as comprehensive. From the Chrysler Pacifica to the Chevrolet Cruze to the Fiat 124 Spider to the Mitsubishi Mirage, NACTOY has covered an enormous price range with this year's contestants. Of course, these are only the eligible vehicles. They'll need to run through three rounds of judging, starting in September at NACTOY's traditional Hell, MI, test drive. The Canadian and American journalists involved in the judging will announce this year's nine finalists – three in each category – on December 6.

GM invests $175 million to replace 3 Cadillac sedans with 2

We've already had confirmation that Cadillac is sunsetting the ATS compact sedan and strong hints that Caddy would discontinue the full-size XTS (pictured above) and midsize CTS, too. Now all three are confirmed, with GM saying it's investing $175 million to build two replacement sedans. GM has already begun installing new tooling at its Lansing Grand River assembly plant in Michigan. That will go toward building two new sedans, which reports suggest are likely to be called the Cadillac CT5 and CT4, or possibly the CT3. It's part of Cadillac's plan to introduce a new vehicle every six months by the end of 2021. A spokesman told the Associated Press that the new cars will debut within that time frame and that the changes won't affect staffing levels at the plant, which employs 2,000 people. Of the three, the XTS is expected to go away entirely, while the CT5 would replace the CTS, straddling the line between a compact and midsize four-door. The CT4 or CT3 would take the spot of the ATS and likely be smaller. That would leave the CT6 as the brand's largest sedan and leave Cadillac with three sedans starting with the 2019 model year. Meanwhile, Cadillac has only one model, its top-selling XT5, representing the all-important and red-hot luxury crossover segment. It's prepping a midsize XT4 crossover for sale later this year as a 2019 model. Cadillac's global sales rose 15.5 percent in 2017, thanks largely to growth in China, but sales in the U.S. fell 8 percent for the year to 156,440 vehicles. Sales of the ATS fell 39 percent, dropped 35 percent for the CTS and 27 for the XTS last year. Related Video:
