The 2020 Cadillac CT6 will be the final model year for the full-size luxury sedan, with General Motors deciding to halt sales in North America and focus its efforts elsewhere. GM still went ahead and applied a number of changes to the vehicle before sending it off into the sunset, though, so lets go over all the differences, updates and new features found on the 2020 Cadillac CT6.
One of the biggest changes is actually tied to the CT6‘s eventual demise. GM sought to simplify the CT6 lineup for its final year of production, discontinuing several trims in the range, including:
|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 change that really grabbed the attention of media and Cadillac fans was the deletion of the Sport trim level, which our sister site Cadillac Society exclusively reported on at the time. The Sport trim level last just one model year, having been introduced for 2019 as part of Cadillac’s burgeoning Y trim level strategy. Cadillac CT6 Sport models are set apart by their gloss black exterior trim, which helps give it a sportier and more sinister exterior appearance. The model comes equipped with GM’s twin-turbocharged 3.0L LGW V-6 engine, which is good for 404 horsepower and 400 pound-feet of torque.
As for exterior changes, the 2020 Cadillac CT6 drops the available Bronze Dune Metallic exterior color and ditches the engine designation badges with new ones that adhere to the automaker’s new torque-based naming scheme. Under the new naming scheme, vehicles will feature a number representative of their torque output in newton meters and rounded up to the nearest hundred. As such, models with the 3.6L LGX V-6 engine have a ‘400’ badge, while models with the available 4.2L twin-turbo LTA/Blackwing V-8 have an 800T badge – the ‘T’ standing for ‘turbo’.
Moving inside, the 2020 Cadillac CT6 does away with the Dark Auburn with Jet Black accents interior color combination. The SAE Level 2 Super Cruise semi-autonomous system also gets an update and mileage expansion that includes more highway coverage in the United States and Canada, as we reported previously.
The 2020 Cadillac CT6 ditches its turbocharged 2.0L LSY I-4 engine, as well as the twin-turbo 3.0L LGW V6 engine (production code LGW) – leaving just the 3.6L LGX V-6 and the 4.2L LTA V-8 in the lineup. It’s worth noting that the V-8 is only available in the well equipped Cadillac CT6 Platinum and the limited production Cadillac CT6-V.
GM also made some subtle adjustments to the way the sedan’s various options packages are bundled together. These include:
- CT6 Luxury model with the 3.6L V-6 engine (LGX) now includes the contents from the Convenience Package and the Driver Awareness Package
- CT6 Premium Luxury model with the 3.6L V-6 engine (LGX) now includes Super Cruise system
- CT6 Platinum model with the twin-turbo 4.2L V-8 Blackwing engine (LTA) now includes the Active Chassis Package as well as 20-inch Platinum Twin 5-Spoke alloy wheels with a Manoogian finish and chrome inserts
That completes the list of changes, updates and new features to the 2020 Cadillac CT6. The sedan is set to end production at GM’s Detroit-Hamtramck Assembly facility in Michigan before the end of the month, though it will remain in production at Cadillac’s Jinqiao plant in Shanghai and will still be sold in China for the time being.
