Cadillac Celestiq previewed as a flagship luxury electric car

Last year, our Autoblog Green editor, John Beltz Snyder, got a sneak peik of GM's upcoming electric car roll out. No photos were given, but he described them in great detail. Now we finally get our own peek at one of those cars, the Cadillac Celestiq flagship sedan. Sadly, we don't get a particularly clear look, since Cadillac is only teasing the car at this point, but it's better than nothing, and better than most teasers. We get a top-down shot that reveals the car will share some key cues with the Lyriq crossover EV. Most obvious is the rear with the boomerang taillights and fastback roof, which is a glass unit separated into four pieces. Each piece can be individually adjusted for transparency, and it appears they can be illuminated as well. The front also appears similar to the Lyriq with a geometric grille covered in a transparent panel. The grille looks significantly larger, though. It also features illumination like the crossover. We also get a look at the interior, which prominently features a full-width screen for instruments and infotainment. There appears to be a screen in the center console/stack that can control functions including the roof panel illumination. According to Snyder, the interior also has extensive wood and metal trim intermingling with nifty ambient lighting. Cadillac didn't say much about the mechanical aspects except the basics. It will use GM's Ultium battery technology that will be shared with other products such as the aforementioned Lyriq and the GMC Hummer EV. It will also feature four-wheel steering as well as all-wheel-drive, undoubtedly courtesy of dual motors, one front and one rear. Cadillac previously confirmed that the Celestiq is headed for production. We also suspect that some of the fancy features such as the screens and multi-panel glass roof could make it to production. This is because it's meant to be a halo product showing off the ultimate in luxury and technology from the brand, and it could have a price tag larger than $200,000. We're expecting Cadillac to fully reveal the Celestiq in a few months, but it could be a while before the production version hits the road. The Lyriq isn't going on sale until late next year, and we would bet the Celestiq wouldn't come ahead of it. Related Video:

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.

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.
