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 clears camo off the XT3 revealing grille, lighting details

Up until now, every Cadillac XT3 we've seen has been buried under covers and vinyl wraps, but one of our spy photographers recently captured a group of them with significantly less camouflage. As a result, we finally get a relatively clear picture of what the car will look like. The nose blends the look of current Cadillacs with cues from last year's Escala concept. The headlights still appear to stretch up into the top of the fenders like its production brethren, but they don't descend as far down the front fascia, a hint of Escala influence. The grille also features more of egg-crate mesh like that Cadillac concept. In profile, we can see evidence of the XT3's smaller size compared with the XT5, mainly in the lack of any glass area behind the rear door. Other evidence of the smaller size is that our spy photographer reports the cars were being tested alongside the BMW X3 and Mercedes-Benz GLC-Class. The profile also shows that the XT3 will have a hard-edged rear end with a rakish hatch. At the back, there isn't a whole lot to report, but the taillights look like they'll be interesting. There appears to be a horizontal element in the middle of the hatch similar to what we've seen on the Escala and the refreshed XTS. We can also see some lights up on the C-pillar, which indicates that the XT3 will also have tall vertical elements up those pillars like on the Escalade. We expect the XT3 to show up late in 2018. It will likely be powered by a turbocharged four-cylinder of some sort, and because it will probably be based on an existing GM crossover or sedan platform, it will probably have front-wheel drive and/or a front-drive based all-wheel-drive system.

1959 Cadillac Eldorado and more featured in latest 'Forza Horizon 4' car pack

It's that time again, time for another Forza Horizon 4 car pack. This one is a bit bittersweet, because while there are some great cars, it will also be the last one included with the Car Pass, which covered every downloadable car pack for a discounted price. So either we won't see many additional cars in the coming months, or we'll be paying extra for them. On a brighter note, the cars in this pack are cool, particularly the 1959 Cadillac Eldorado Biarritz convertible. Threading this aircraft carrier of a car through British streets should be highly entertaining. It's also stylish as all get-out. There are more appropriately sporty cars coming, too, including the 1994 Honda Prelude Si, 1994 Nissan Fairlady Z Version S Twin Turbo and the all-new TVR Griffith. Some reward cars being added come from the role-playing video game Final Fantasy XV. They're the Quartz Regalia Type F and Type D. The Type F is another big luxury convertible in the vein of the Cadillac, and the Type D is the monster truck version. The car pack is available now, and is free to owners of the $29.99 Car Pass. The individual car packs are available for $6.99 separately, and individual cars are even available for $2.99 a piece if you only want specific ones.
