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.

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.

2021 Cadillac Escalade price increases take starting price to $77,490

Update: This story has been updated with official pricing from Cadillac that includes the destination charge and pricing for the long wheelbase ESV model. The modified story continues below. As the 2021 Cadillac Escalade prepares behind-the-scenes for duty in front of real-life red carpets, more information on the brand new fifth-generation SUV bubbles to the surface. GM Authority got its hands on some MSRP figures the other day, but we have the official pricing from Cadillac now. GM kept pricing of the other full-sized SUV family — the Tahoe, Suburban, and Yukon — unchanged or close to the outgoing models. Escalade intenders will be happy to know the same goes here, the 2021 example priced at $77,490 after a $1,295 destination charge is added in, only $1,000 more that the soon-to-be retired 2020 Escalade for a fancier cabin and lots of new tech inside and out. Cadillac reworked the trim walk for 2021 to its Y-trim configuration, splitting into Luxury and Sport models above the base trim. There were four options in 2020, not including all-wheel-drive versions: Base, Luxury, Premium Luxury, and Platinum. There are five for the new year: Luxury, Premium Luxury, Sport, Premium Luxury Platinum, and Sport Platinum. The switcheroo makes it hard to compare all but the bottom and top trims, but the price walk for rear-wheel-drive versions goes: Luxury: $77,490 Premium Luxury: $84,290 Sport: $86,890 Premium Luxury Platinum: $101,290 Sport Luxury Platinum: $101,290  Add $3,000 to any of those trim prices, and you'll have the corresponding long wheelbase ESV price. Four wheel drive is a similar $3,000 charge on any trim. That means the base price on the top trim Escalade ESV with four-wheel drive is $107,290. The 2021 Platinum models are $7,700 more than the 2020 Escalade Platinum. The standard engine is the 6.2-liter V8, shifting through a 10-speed transmission. And the 3.0-liter Duramax diesel is a no-cost option, so take your pick. Customers could end up waiting for the Escalade as well, depending on when every kind of manufacturing can restart in earnest to serve the Arlington, Texas, plant all the parts it needs to build the new SUV.
