General Motors launched the second-generation Cadillac CT6 for the 2024 model year, offering the large four-door luxury sedan as a Chinese-market exclusive. Compared to the first generation, the second-gen CT6 features a variety of updates and changes, including a new exterior design that takes after the Cadillac Expressive Coupe Study, as GM Authority highlighted previously. Now, we’re taking another look at the new CT6, this time comparing it to the exterior design of the first-generation CT6.

Let’s start up front. The fascia design for both models includes a few similar design features, but they definitely stand apart as well. The grille, for example, incorporates a crest-like shape on both models, while the grille insert differs between generations and trim levels. The grille in the second-generation also appears to be larger, with more pronounced styling lines in the lower bumper. The lighting for the second-generation shows thin upper lighting signatures in the corners of the fascia, plus horizontal lighting elements on the sides, the latter of which provide the primary illumination. Meanwhile, the first-gen model incorporates single-piece lighting housings, with the primary lighting elements higher in the housing and vertical signatures on the sides of the fascia.

Moving to the profile, the second-generation Cadillac CT6 has a more graceful, sloping silhouette compared to the first generation, with a gently curving roofline that extends down into the trunk. This contrasts with the more square, three-box shape of the first generation. The second generation also has a rake along the belt line, enhancing the sleek side view.
Finally, in the rear end, we find similar V-shaped taillight clusters, with thinner housings for the second-gen, while the trunk on the second generation has a more pronounced lip. The exhaust outlet treatment is different as well, with the first generation sporting a set of rounded pipes, and the second generation showing off trapezoidal exhaust finishers.

In terms of dimensions, both models have an identical 122.4-inch wheelbase, while the overall length is slightly shorter with the second generation. The second generation is also slightly wider and slightly taller.

Why Cadillac doesn’t bring the CT6 back for the US market is a mystery. Lincoln vacated the segment. Even the Chrysler 300 is dead. It’s only competition is the large Lexus and German brands and I guess the big Volvo. With some astute product selection and marketing, Cadillac could reclaim a portion of the segment it used to dominate.
I had to have a Cadillac ct6, I finally got one I got a 2018 3.6l.. I loved the car, however I had major issues with the car. My cars transfer case was bad and if you know anything about the ct6 before the 2019-2020 models the all wheel drive transfer cases and transmissions were a huge problem. My car sat for over six months waiting on a new transfer case and there was only one and the dealership wouldn’t sell it that had it. The part was in national back order then the transfer case went under an engineering changed which continued to fail quality inspection. Finally GM did a repurchase of my vehicle and I wiped my hands with it.. I feel everyone that has gone thru the issues with the ct6 is the reason why no one including GM isn’t goin to bring it back to the us. Just my opinion the ct6 was a super fail in every aspect.
Same problem with mine. Cadillac cant fix it because the discontinued the part!!!! Another screw you from GM….
Having a 2017 CT6 Premium AWD, AWS, Super Cruise and a 2020 CT6 Premium Luxury AWD, AWS, Super Cruise, I am disappointed in the fact that GM cancelled it for the US, where Cadillac was born, and it lives on in communist China. What a disaster for GM and Cadillac. The sedan market is not dead in the US as GM/Mary Barra seems to think. I for one, and many others on this forum and in the marketplace, will not purchase an SUV/CUV or whatever they want to call them, no EV for many of us as we travel and have “EV mileage anxiety” as it is called at my Cadillac dealership. The CT4 is a compact car and the CT5 isn’t much larger. I have had both as loaners when I have taken one of the CT6’s in for routine maintenance. Neither one of them can carry 4 adults and they do not offer the same ride quality as the CT6.
I will be looking at sedans when I go to purchase my next luxury car, and it won’t be a Cadillac…Mercedes, Genesis, Audi or BMW will be on my shopping list. If GM would bring the CT6 back and MARKET the car, they would be surprised with the traffic it would bring.
Mary Bara has CT6-a-Phobia.
When my CT 6 croaks I’ll never buy another Cadillac that she is trying to shove down our throats.
Will never buy another Cadillac horrible service and bad experience.. loved my ct6 but to many problems.. just bought a Mercedes s450 and love it.. Cadillacs aren’t built like they use to be.. break down to easily and drop in value drastically.
GM motto.. Cost cut at any cost…………
I have a 2016 ct6 , great car…..only 50k miles …..but having the issues with the transmission. Should I sell it while it stilll running fine? Or go for another flush and might another cpl years out of it ?
I would tell them to look at the transfer case… GM paid my car off gave a 3500$ voucher towards a new car and gave me 4000$ cash… was called a buy back… n that was on a 2018 3.6l awd premium luxury
Dont worry all, Cadillac will be gone in five years…
I have a 2018 CT6 3.0L T.T. Platinum Version and I absolutely love it. I have owned four Cadillacs now. a 1995 Sedan DeVille which I was restoring to show room condition until some smashed it on me. a 2007 STS, a 2016 CTS and now the 2018 CT6 3.0L T.T. Platinum Version which I think is fabulous. It is so sophisticated that my son has named it “The Starship Enterprise.”
