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.

Cadillac to move select offices from Detroit to Manhattan?

Under Johan de Nysschen, Infiniti moved its headquarters from Yokohama, Japan, to Hong Kong. Now at Cadillac, it appears the company's new president could be planning a relocation of at least some of the brand's operations from Detroit to Manhattan, according to a new report from Reuters.
In the case of Infiniti, de Nysschen pushed for the move because moving away from the brand's Nissan overlords would allow it a bit more freedom. It's evidently a similar case for Cadillac, with Reuters speculating that such a move would help distance the brand from the corporate culture in Detroit. A Big Apple move could also attract new talent that may have considered a job with the brand but were put off by the idea of living in Detroit.
It's important to note that if such a move takes place, it likely won't affect the folks actually responsible for developing the brand's vehicles. Instead, administrative functions, including marketing, could be the focus of the relocation.

2021 Cadillac Escalade ESV spied uncovered

The 2021 Cadillac Escalade made its big debut a little over a week ago, complete with its fancy interior and displays, but the company has only shown the short-wheelbase model. One of our spy photographers has picked up the slack and caught the long-wheelbase ESV model cruising around southeast Michigan without any camouflage. It's pretty much what you would expect: an Escalade but longer. But it does have a couple subtle differences. Those differences lie in the sides of the Escalade ESV where the length makes some changes. The wheelbase is indeed longer, not just the body, as evidenced by the rear wheels sitting farther back from the edges of the rear doors. Those doors are also a bit longer, so rear seat access should be a little better with this lengthened Escalade. Another change is in the stylized C-pillar. It's a bit more difficult to see since this is a Sport trim with black trim, but the C-pillar is substantially thicker, and the rear edge leans forward more than on the shorter version. This reworked trim probably helps hide the ESV's extra length somewhat. The extra thickness might hinder some rear and side visibility, too. The Escalade ESV will make its formal debut at the upcoming New York Auto Show, and we expect it will go on sale at the end of this year at about the same time as the short-wheelbase version. The extra length will probably also bring a little extra cost to the base price. Pricing for the 2021 Escalade has not yet been announced, though. It will probably be revealed closer to the luxury SUV's on-sale date. Related Video:
