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.

2023 Cadillac Lyriq vs Tesla Model Y, Audi E-Tron, Jaguar I-Pace | Specs compared

The 2023 Cadillac Lyriq is the latest electric luxury crossover to enter a quickly growing segment. It brings with it the company's trademark creased design language along with high-tech features and an impressive amount of range. The Cadillac also happens to have a price and specifications that put it square in the middle of a competitive group, so we had to line up the numbers to see how it compares. We've gathered up a selection of premium electric crossovers including the Tesla Model Y, Audi E-Tron and Jaguar I-Pace, all of which seem like the closest rivals for the Cadillac. We've assembled all the raw numbers in the chart below. We've also got some additional analysis below that. And now, onto the data. Power, range, efficiency Interestingly, the Cadillac is the least powerful of the bunch. This is a bit surprising considering that GM will have a 1,000-horsepower electric Hummer pickup coming out soon. But in the Lyriq, Cadillac only uses a single electric motor powering the rear wheels. While its 340 horsepower and 325 pound-feet of torque should be more than adequate, it falls short of all the dual-motor, all-wheel-drive competition. Because Tesla does not provide horsepower or torque numbers, we're not sure how much the base model makes. We assume it's close. The true power fiends will likely want the optionally available Model Y Performance, though. It also doesn't have publicized power numbers, but its 0-60 mph time of 3.5 seconds suggests its substantially more powerful than the other crossovers, here. Power is all well and good, but range is arguably more important for an electric car. The Tesla is on top, here. The base Long Range trim has an estimated range of 326 miles. The company doesn't specifically say how large the battery is for it or the Performance, which goes 303 miles. The Cadillac is close behind with a current estimate of more than 300 miles on its 100-kWh battery. Cadillac doesn't say whether that number is the gross amount or the usable amount. The Audi and Jaguar lag behind with less than 250 miles from their 95- and 90-kWh batteries, respectively. Audi is the only company that notes that the usable capacity is less than the total, which is a common strategy employed to extend the life of the battery and to maintain consistent ranges over time. 2020 Audi E-Tron View 13 Photos While not as broadly discussed as range, we also wanted to touch on efficiency.

GM doubles miles open to its Super Cruise technology

DETROIT — General Motors said on Wednesday owners of certain vehicles equipped with its Super Cruise assisted driving system will now be able to use it on 400,000 miles (643,740 km) of North American roads, doubling the current operating area as Tesla and other automakers race to deploy hands-free cruising technology. GM's Super Cruise system, like Tesla's Autopilot system, is a driver assistance system, and does not enable true autonomous driving. Spurred by Tesla's aggressive deployment of Autopilot, and Tesla Chief Executive Elon Musk's promises of a more advanced "Full Self Driving" system, GM, Ford, Volkswagen and Mercedes-Benz are racing to deploy competing partial automation technology in major markets. At the same time, safety regulators are showing concern that drivers do not understand that Autopilot and similar systems are not designed to take over driving in every circumstance. The GM system's sensors and software allow a motorist to cruise with hands off the wheel on highways that have been mapped in detail. But the driver is expected to stay alert and ready to take over the car. GM uses technology to monitor the driver, and Super Cruise will sound alarms or slow the car to a stop if it detects that a driver is not responding. Starting later this year, GM plans to enable vehicles equipped with Super Cruise and the company's latest vehicle electronic system to operate hands-free on major, undivided highways in the United States and Canada, as well as additional miles of divided, interstate highways. Currently, Super Cruise operates only on interstate, divided highways. The expansion, enabled by wider digital mapping, will allow owners of properly equipped GM vehicles to cruise hands-free on stretches of Route 66 and the Pacific Coast Highway in the U.S. West or the Trans-Canada highway in Western Canada, GM said. Many of the new roads GM has mapped are in rural, heartland states where GM pickup trucks are popular. GM plans to offer Super Cruise as an option on its Chevrolet Silverado and GMC Sierra large pickups later this year. GM has said previously it intends to offer Super Cruise as an option on 22 models by the end of 2023. Depending on the model, Super Cruise costs $2,200 to $2,500 to add as an option.
