General Motors leveraged its keynote address at this year’s Consumer Electronics Show to provide a glimpse of the Cadillac Celestiq. The Celestiq is an upcoming battery-electric sedan that is expected to serve as the brand’s flagship product.

Based on GM’s Ultium battery platform, the Celestiq is going to be a large sedan. Although a clear view of the Celestiq has yet to surface, today’s teaser confirmed a reasonably large footprint. GM says the big sedan will have a low profile and rearward proportions, two things expected of a large luxury sedan.

Cadillac says each Celestiq will feature “a curated selection of hand-crafted materials, and each CELESTIQ will be designed to reflect the individuality of its owner.” The comment suggests a high degree of customization and aligns with earlier rumors that the Celestiq will be a low volume, very expensive sedan.

Adding to the luxury, Cadillac confirmed the car will feature all-wheel-drive, four-wheel steering and a full glass roof. The glass roof will actually be a point of innovation for Cadillac. It will feature a four-quadrant, suspended-particle-device smart glass. With this smart glass, each occupant of the vehicle can set their own level of roof transparency. Cadillac demoed the technology in today’s keynote.

Today’s teaser also flashed a new massive display on the Celestiq dash. Similar to that of the Escalade, the Celestiq will extend the curved glass to both ends of the dash panel.

The Cadillac Celestiq is expected to enter production sometime next year, following the upcoming Cadillac Lyriq as the brand’s second electric vehicle. Expect it to compete directly with the likes of the Tesla Model S and upcoming Mercedes-EQ S.
