Cadillac Celestiq Features A Unique Roof Fin Antenna

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.

  2. Slow news week – granted – but the shape of the antenna? Hahaha…

    To me the major point of the car is that it looks like it got the AMC HORNET/ Gremlin treatment from 50 years ago. Of course the self-deprecating AMC adds just poked fun at themselves for having a chopped up HORNET compact.

    The CELESTIQ to me looks like a LYRIQ being put through a wringer.
    To me, all that silly electronic crap doesn’t make it either LUXURIOUS nor Desirable. It doesn’t go very far, is heavy, takes a fair amount of electricity to deliver a few passengers to their destination; obviously someone paying mid $300,000 for this won’t care but the point is the car will be very obsolete by the time they sell any to speak of. The same issue applies to a somewhat less extent to the upcoming Escalade IQ all electric. Whereas a base 2wd model is available in the gasoline version, as well as here-to-fore a now discontinued very small (200 odd hp) diesel, there is nothing remotely the same available for the large Electrified Escalade.

    KIA did *NOT* that mistake in that they offer a huge battery with corresponding great mileage for a HUGE vehicle, with something like 210 hp. I’ve driven a friend’s 2wd model who lives in very heavy snow country, and the weight of the battery should keep the traction just fine in the winter time… The car has more than adequate power to keep up at thruway speeds.

    But as I say, the one size fits all super overpriced electric will just *HAVE* to impact sales. They learned their lessons with the LYRIQ to not over price it. So what happened? Managers don’t talk to each other at GM?

    Probably a good thing they will only ‘hand-craft’ a few hundred. Can’t see the sales appeal of the thing at half the price.

    By the way the reCAPTCHA security thing here is pointless and a waste of time, and further, doesn’t begin to work correctly.

  4. According to Tony Roma, the chief engineer of the Celestiq, all comms are handled via antennae embedded in the front windscreen. The shark fin is only for the camera. This was per an interview with him on Top Gear Youtube I believe.
