Just last week, GM Authority provided exclusive information on the upcoming Cadillac Celestiq luxury sedan, the new range-topping, all-electric flagship in Caddy’s vehicle lineup, which will come equipped with SPD-SmartGlass Nanotechnology. Now, we have further information on the benefits of this cutting-edge glass tech, including how it could increase driving range.
In case you missed our coverage last week, SPD-SmartGlass Nanotechnology is a special kind of glass that allows on-demand control over the glass opacity, thus allowing either more or less light into the cabin, as desired.
Equipped on the new Cadillac Celestiq, SPD-SmartGlass Nanotechnology will be used for the luxury sedan’s glass roof, which will enable passengers to control individual quadrants of the roof and set their own preferred opacity.
Obviously, this is great for passengers, but the tech could also help to increase driving range for the all-electric Cadillac Celestiq. For starters, the glass can reduce cabin temperatures, as indicated by Joe Harary, CEO of Research Frontiers, makers of SPD-SmartGlass. In an interview with GM Authority Executive Editor Alex Luft, Harary said that the glass can help to reduce cabin temps by 18 degrees Fahrenheit when equipped on a vehicle with a small sunroof. The Cadillac Celestiq has a full glass roof, which means the benefits could be even greater.
As a result of the cooler cabin temps, there is reduced reliance on the air conditioning system to keep things comfortable. Less A/C use means less electricity used by the compressor, and thus, more electricity for overall range. What’s more, automakers can equip smaller A/C compressors, and thus reduce weight, netting even further range benefits.
According to Harary, Continental Automotive ran a study that found SPD-SmartGlass could increase electric vehicle driving range by 5.5 percent thanks to the cooler cabin temps. What’s more, the study found that the glass tech would reduce CO2 emissions by 4 grams per km when equipped on an ICE-powered vehicle.
The Cadillac Celestiq was initially slated for a debut in April, and later delayed to a summer date. Now, however, the delay has been extended a bit further, although the sedan is on track for a launch with the 2024 model year, starting at roughly $200,000.
