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.

Timothee Chalamet is 'Edgar Scissorhands' in Cadillac's Super Bowl commercial

Filmmaker Tim Burton's 1990s classic "Edward Scissorhands" explored the unusual challenges of a boy who had scissors for hands. One challenge that was not touched on in the original film was that of driving a car. For its Super Bowl commercial, Cadillac revisits the theme, and the brand's Super Cruise hands-free driving feature proves perfectly suited to "Edgar Scissorhands," another young man with scissors for hands. Playing Edgar is Timothee Chalamet, reprising the role that Johnny Depp made famous as Edward. Edgar's mother is portrayed by Winona Ryder. While Edgar's unique hands do give him some special talents — he makes one heck of an artful salad, for instance — they present a challenge in many others, such as playing football. A virtual reality headset affords Edgar the ability to drive, and that gives his mother an idea. She presents him with a Cadillac Lyriq, the not-yet-on-sale EV crossover. Edgar sets the button to activate Super Cruise, and the Lyriq steers itself. The perfect solution for someone with scissors for hands. Why feature a vehicle that doesn't go on sale until late 2022 when Super Cruise is available in other Cadillac models now? The answer seems to be that GM is using its Super Bowl commercials to also showcase its pivot to EVs. Certainly, that's the theme of "No Way, Norway," which stars Will Ferrell along with the Lyriq and the Hummer EV.   Related Video:

2014 Cadillac CTS debuts new design, twin-turbo power, Vsport model [w/video]

If ever there were a Cadillac to truly rival the world's best, this could be it.
With every new model, Cadillac indeed gets closer and closer to actually performing at the top of its class, rivaling those crafty Germans at their own sport/luxury sedan game. The best example yet of Cadillac's efforts to challenge the world came last year, when we met the 2013 ATS - a vehicle that we praised for its on-road dynamics and interior refinement, and later went on to be named North American Car of the Year.
