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.

2013 Cadillac ATS Premium 2.0T 6MT

The new Cadillac ATS is an impressive sport sedan, often considered one of the most serious threats to the BMW 3 Series. Unlike GM's previous attempts, this four door brings aggressive styling, commendable chassis dynamics and class-leading handling to the highly competitive battle. And, like its daunting German foe, Cadillac offer several powertrain choices.
I recently spent time with the ATS 2.0T Premium on my home California turf. Fitted with a turbocharged 2.0-liter four-cylinder engine mated to a six-speed manual gearbox with a limited-slip rear differential, my tester was lightly optioned, with only a paint upgrade and a cold weather package. That brought the as-tested price to $46,305, configured the way I imagine most enthusiasts would prefer. This meant I fully expected to enjoy a week with a tossable sport sedan that boasted "fun-to-drive" as its middle name, but all was not well...

Cadillac prices the 2020 XT6 crossover from $53,690

Cadillac has announced official pricing for its new XT6 crossover, built in Tennessee. The three-row XT6, Cadillac's first big crossover, starts from $53,690 when it goes on sale later this spring. For that, Cadillac offers the "Premium Luxury" trim level model with front-wheel drive; AWD is optional. Above the Premium Luxury is the XT6 Sport, which comes standard with AWD and starts from $58,090. Both prices include destination charges. The sole engine at this point is the 3.6-liter naturally aspirated V6, which produces 310 horsepower and 271 lb-ft of torque; the transmission is a nine-speed automatic. The Premium Luxury and Sport differ visually, with the former offering more chrome and wood, while the latter has blacked-out trim in place of chrome and carbon trim instead of cabin wood. The wheel design is different between the trim levels, and the Premium Luxury has red taillights while the Sport version has clear tails. The Sport model has continuously adjustable shock absorbers. Both models have seven airbags as standard, as well as an HD rear camera, forward collision alert, automatic emergency braking and front pedestrian braking, front and rear park assist, lane change and blind spot alert, lane keeping assist and lane departure warning and rear cross traffic alert. The lighting is LED front and rear; inside, a heated steering wheel is standard, as is a power folding third-row seat and a remotely folding second-row seat. Seven-passenger seating is standard, and a six-passenger setup is optional with captain's chairs for the second row. There are option packages such as the Enhanced Visibility and Technology Package, which adds an eight-inch gauge cluster display and an HUD, both in color, HD surround vision with recording, and automatic parking assist with braking. The Driver Assist package adds adaptive cruise and enhanced AEB, and one can also specify night vision. The XT6 charges phones wirelessly and is Apple CarPlay and Android Auto compatible as standard. It also has a 4G LTE Wi-Fi hotspot with 3GB or three months' worth of data thrown in, and phones are paired via NFC. Cadillac is taking orders for the XT6 starting in March.
