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.

Expensive Cadillac ELR at least comes with free Level 2 home charger

"But wait, there's more!" Anyone who's watched late-night television is familiar with the telltale phrase of a spokesman looking to reel in a potential customer who may otherwise be disinterested in what's being advertised. Now, General Motors, faced with selling the first Cadillac extended-range plug-in vehicle to a public that may find it rather expensive, is throwing in a bonus. In this case, GM will give away a 240-volt home fast charger to "early" buyers of the Cadillac ELR, including professional installation. How early? Well, we're not finding that information in the press release below, so it may be a moving target. Earlier this month, GM said it would offer the ELR for a 39-month lease for $699 a month for qualified lessees. The deal requires $5,999 down and GM originally said it would only be good until the end of the month (though we assume that could change). It's also an "ultra-low-mileage" lease that allows for only 10,000 miles of driving each year, before per-mile surcharges of 25 cents kick in. Last fall, GM set the base price for the ELR at $75,000, before government incentives get factored in. Like its Chevy Volt sibling, the ELR can go about 340 miles using both the electricity in the battery and the gas-powered on-board generator. Check out our ELR First Drive here. Cadillac Enhances ELR Buying Experience Early adopters to receive complimentary home charger and installation DETROIT – Cadillac is offering a complimentary 240-volt home charging station and installation to early buyers of the all-new 2014 ELR electrified luxury coupe. "The ELR's blend of leading technology with provocative design and fun-to-drive performance is set to bring new buyers to Cadillac and to electrification itself," said Uwe Ellinghaus, chief marketing officer, Global Cadillac. "Professional installation of the fastest home-charging unit is a natural way to mark the introduction of ELR to the luxury market." Cadillac is offering the ELR on an ultra-low-mileage, 39-month lease for qualified lessees at $699 per month with $5,999 due at signing after all offers. The Cadillac ELR offers a convergence of luxury, electrification and sporty driving in a premium coupe with dynamic design and an award-winning range-extended electric powertrain capable of 340 miles of total range.

Weekly Recap: New bosses try to jump-start Cadillac and Lincoln

Both of America's domestic luxury brands seem to be stuck in neutral.
It's ironic that Cadillac and Lincoln got new bosses within days of each other this month. It's also a commentary on the fact both of America's domestic luxury brands seem to be stuck in neutral.
