The Cadillac CT6 is one seriously great vehicle that was made even better by the 2019 model year refresh. Meanwhile, the 2020 Cadillac CT6 is getting a few updates and change before production of the large ends at the Detroit-Hamtramck plant later this month. Here are the changes, updates and new features that are different for the 2020 CT6.
Arguably the biggest change for the 2020 Cadillac CT6 were the discontinuation of various models within the range, including the following:
| Model | Trim Level | PEG Code | Engine |
|---|---|---|---|
| 6KH69 | Luxury | 1SA | Turbo 2.0L I-4 LSY |
| 6KHJ69 | Premium Luxury | 1SC | Turbo 2.0L I-4 LSY |
| 6KM69 | Platinum | 1SN | Twin-Turbo 3.0L V-6 LGW |
| 6KL69 | Sport | 1SJ | Twin-Turbo 3.0L V-6 LGW |
One of the most noteworthy changes is the deletion of the Sport trim level, which Cadillac Society exclusively reported on. Introduced only for the 2019 model year as part of Cadillac’s new Y trim level strategy, Sport models feature a more aggressive appearance by removing many of the traditional shiny chrome bits and replace them with darker hues. The model came equipped with the twin-turbo 3.0L engine making 404 horsepower and 400 pound-feet of torque and looked really sinister.
The changes leave the 2020 CT6 with only two engines – the naturally-aspirated 3.6L V-6 (production code LGX) on the Luxury and Premium Luxury models, as well as the twin-turbo 4.2L V-8 Blackwing (production code LTA) on the Platinum model.
On the outside, the 2020 Cadillac CT6 loses the Bronze Dune Metallic exterior color while also updating the engine designation badges, as per the automaker’s new torque-based nomenclature. The 3.6L models get the 400 badge while the 4.2L Twin Turbo gets the 800T designation.
Inside, the 2020 Cadillac CT6 deletes the Dark Auburn with Jet Black accents color combination. The Super Cruise system also gets a mileage expansion that includes trunk roads, as reported previously.
On the mechanical side, the 2020 CT6 loses turbo-charged 2.0L I-4 engine (production code LSY) as well as the twin-turbo 3.0L V-6 engine (production code LGW). The luxury sedan also loses the engine block heater option.
The final changes are to the various packages, as follows:
And that rounds out all the changes, updates and new features to the 2020 Cadillac CT6.
Unfortunately, the large sedan is not long for this world, with production scheduled to end at the end of January. It’s currently unclear whether Cadillac plans on moving production elsewhere, or importing the vehicle from China. As of this writing, both scenarios look highly unlikely.
Note that the changes described herein apply only to the U.S. market. Changes for other markets may differ.One of four new colors for the 2025 model year.
And it now represents the best value in its segment.
