Cadillac Celestiq flagship EV shows off its tint-shifting smart roof

GM has high hopes for its upcoming Cadillac Celestiq sedan, slated for release in 2023. The flagship EV is being built to help the brand recapture its reign as “the Standard of the World.” As such, itÂ’s expected to arrive packed to the gills with cutting edge, futuristic technology including an all-glass roof that can adjust its opacity anywhere between crystal clear and completely opaque with the mere flick of a switch. These roofs, dubbed SPD-Smartglass, have been designed and manufactured by Research Frontiers of Woodbury, New York, and are based on Suspended Particle Device technology that was originally created as a replacement for the manual sliding window shades aboard commercial aircraft, Research Frontiers CEO Joe Harary told Engadget. Some of the earliest examples of SPD window treatments can be seen on the 2011 Mercedes Benz SLK roadster and in the 2012 Mercedes S Class coupe, which were used to increase headspace while eliminating the physical window shade screens, as well as various McLaren models over the past decade. As the YouTube video below explains, Research Frontiers SPD tech relies on polyiodide nanoparticles to generate its tint effect. Magic Sky Control Using SPD-SmartGlass Technology “SPD technology is smart glass that allows you to change the tint of the glass,” Harary explained. “There's this film that we invented that has little nanoparticles in it, which you can control with a small electrical voltage. So, basically this film... that allows you to dial in whatever tint level you'd like.”  “The crystals are about three to five tenths of a micron in length and they act as induced dipoles so when you apply an electric field to conductive coatings in the film,” Harary continued, “ the particles will line up, and allow light to pass through. Then, when you remove the voltage, their natural tendency is to be in the dark state due to Brownian movement and that causes the glass to tint.”  As the tint partially blocks incoming photons, it also reduces the amount of glare experienced by the driver and the heat trapped within the vehicle — over 99.5 percent of light and 95 percent of heat, per a January press release from the company. The claim is, this allows vehicle occupants to stay comfortable for longer without having to turn on the A/C, as well as keep the interior up to 18 degrees Fahrenheit cooler overall, Harary said.

2021 Cadillac Escalade First Drive | Opulence at a cost

The Cadillac Escalade is one of the most recognizable cars in America, both on the road and in the minds of consumers. It is equal parts profit machine and pop culture icon, and it sits atop GM’s heavy-hitting hierarchy of body-on-frame SUVs. Sure, Cadillac may hold most of the cards in the luxury SUV marketing game, but itÂ’s not the only player. For starters, the Lincoln Navigator is quite good, and it takes a very similar approach to truck-based luxury. Both are flashy, cushy and high-tech, and their tuning acknowledges that driving dynamics will never be the strong suit of vehicles this large – though ride comfort certainly can be. To make matters worse, the Europeans are getting serious about their three-row SUV game, and while they may not offer the same body-on-frame capability you get from the Americans, they more than make up for it with brand prestige and state-of-the-art engineering. With such solid competition, Cadillac was not in a position to just phone in the EscaladeÂ’s redesign. The highlight of that effort is a new platform, shared with the new Chevrolet Tahoe and GMC Yukon, that finally features an independent rear suspension. There's also the gorgeous and tech-rich interior featuring a 38-inch curved OLED dash screen, a new diesel engine option and – stop us if youÂ’ve heard this one before – Super Cruise. While the Escalade does share its fundamentals with the Tahoe and Yukon, the Cadillac-branded variant of GMÂ’s big truck platform always gets special treatment. Only the very base model is available without a leather interior, for example, and the aforementioned in-cabin tech is exclusive to the Escalade. YouÂ’re also limited to just two engine options: the standard 420-horsepower V8 that's the range-topping option on GM's other SUVs, and the new 3.0-liter Duramax turbodiesel inline-six that's good for 277 hp and a V8-matching 460 pound-feet of torque. Both are paired with GMÂ’s 10-speed automatic transmission, and thereÂ’s no price difference, regardless of trim.   Like CadillacÂ’s other offerings, the 2021 Escalade has a split trim hierarchy. Above the base model, you can choose one of two paths: Premium or Sport. The Premium Luxury and Premium Luxury Platinum are your more traditional, flashier options, with lots of chrome and a rich, warm interior. The Sport and Sport Platinum are for those who prefer a more modern, subtle aesthetic, with blackout exterior trim and more subdued interior finishes.

Cadillac CTS-V spotted with big exhaust, new grille?

If you thought Cadillac was content to leave its twin-turbocharged Vsport as the range-topping CTS, think again. Behold, our first good glimpse at the next-generation Cadillac CTS-V sedan, sporting more aggressive styling (somewhere under there), meaty quad-exhaust pipes, and what very well could be a new face for the V-badged Caddies.
Creating an all-new grille design seems like an awful lot of work just for a prototype, so it's very possible that the vertical-bar treatment you see here could make its way into production. Our spy photographers have pointed out that they've seen this same sort of grille treatment on prototypes for the smaller ATS-V sedan, and we've heard V-series models may soon have greater differentiation from the standard vehicles that sired them - that seems especially necessary if Cadillac insists on expanding this whole Vsport range.
Regardless of how its front end looks, the CTS-V ought to be a real monster. Industry sources say we can expect to see a supercharged version of General Motors' 6.2-liter V8 under the Caddy's hood, and considering the current car already makes 556 horsepower and 551 pound-feet of torque, we wouldn't be surprised to see a decent increase in both of those numbers. After all, one of the CTS-V's main competitors, the Mercedes-Benz E63 AMG, is currently putting out 550 hp and 590 lb-ft of torque. Could this mean a 600-hp Cadillac is on the horizon?
