The 2025 Cadillac Celestiq is sleek as can be, featuring a sloping, fastback-like profile and a low-slung silhouette. There’s not a part of the ultra-luxury electric sedan’s exterior that detracts from its incredibly streamlined design, including its comms fin mounted just fore of the rear hatch window.
All Cadillac sedans – the Celestiq, CT4, CT5, and both generations of the CT6 – feature a “shark fin” style comms antenna. This feature is named, quite obviously, for its pointed design similar to that of a shark’s dorsal fin. These antennae jut out well above the roofline and aren’t particularly subtle, and may look out of place.
The Cadillac Celestiq, however, incorporates a different, more subtle design for its comms antenna. Instead of a shark fin-like antenna, it features a broader, smoother shape that isn’t as upright as that of other Caddy sedans. Look closely, and you’ll see that the Celestiq’s fin is a lot shorter than those on the CT sedans, hugging the ultra-luxury sedan’s roofline and being less jarring, too.
Additionally, the antenna on the Celestiq (as well as on the CT5 and CT6) also incorporates the lens for the Rear Camera mirror, providing a high vantage point for the unique feature.
As a reminder, the Cadillac Celestiq was initially expected to launch as a 2024 model year vehicle, but as Cadillac Society recently reported, the first assembled customer units will be classified as 2025 model year vehicles. The ultra-luxury sedan rides on the BEV3 platform and harnesses a 111 kWh battery pack and a dual-motor all-wheel-drive propulsion system, which provides 300 miles of driving range on a single charge while delivering 600 horsepower and 640 pound-feet of torque.
Production of the Celestiq kicked off in January. The vehicle is assembled almost entirely by hand at the GM Global Technical Center in Warren, Michigan, save for certain battery, frame, and drivetrain components.
