2020 Cadillac CT6: Here’s What’s New And Different

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.

Model Line

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.

Exterior

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’.

Interior

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.

Mechanical

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.

Packages

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.

  1. The car is incredible. One of the top technological vehicles ever produced. It unfortunately was produced smack in the middle of a shift to SUVs preferred by Americans combined with tariffs on foreign built vehicles from China. Would love to get my hands on a blackwing, i figure those will be collector items for the years to come, especially with Cadillac planning on full electric by 2030.

    1. Incredible? Agree. We had an ’18 Platinum; traded it on a ’19. Wonderful car. If you travel long distances, SuperCruise is amazing.

  2. Beautiful vehicle,

    If this vehicle was pushed by Cadillac from the start with the options as of now, where would it be ?

    We will never know !

  3. CT6 V 800T AWD What an inspiring “name”! No wonder it’s dead. My washing machine has a more inspiring name that evokes more of a psychological connection.

    1. Hum….Mine is actually a Maytag Maxima…..GM and their Pontiac Free Agents going to Nissan were a bit wrong there, but it is one hell of a Washer…..and looks better than some of GM’s latest designs too!

  4. So they built a car that can drive you on long highway trips by itself and they’re going to put batteries in to prevent you from doing it, they’e genius’s.

  5. I love this car…My wife and I just took delivery of a 2020 CT6 Luxury, V-6, AWD. Of our 17 new Cadillacs this is one of our favorites. Its beautiful, roomy, comfortable and classy. It is everything a Cadillac should be. I think discontinuing it is a huge mistake. Cadillac is “BIG CAR COMPANY” and should make big cars.

  6. I own a 2018 CT6 Premium Luxury model with Super Cruise. Amazing Tech. Great Vehicle.

  7. Glad I was able to find a 2019 CT6 Sport 3.0TT w/ Supercruise before they were all gone. It’s a great vehicle!

  8. More GM genius at work here. Spend untold amounts of money developing this flagship worthy car, then even more on a radical flagship V8 engine then turn around and drop the entire thing once they get things right. They have a known history of doing this exact thing over and over and over again. The very definition of insanity is doing the same thing again and again and expecting a different result- the very definition of why GM is slowly failing and will mostly likely not be around after this decade.

  9. They should’ve built it with an LT1 Engine. Then they could call it the CT6.2

  10. I love my CT6 Prem. Luxury, could’ve had a better interior, but I’ve gotten over 30 mpg on road trips, done with GM after this. Spend over $100 mil. to merge Steel and Aluminum in a production line and then dump the results. DONE

  11. I’m not really sure what to say. I have had two ELR’s still have a V-Wagon (manual of course) and drive a 2019 CT6 3.0TT Sport- love(d) them all, but they were all killed off! Hope its not me…

    That said, yesterday i was at the dealer for an oil change and drove a CT5- I really really hope that the V is better than the 4 banger I was in, but for a sticker that was $55k, the car was mediocre at best. No front or surround cameras, average Bose sound system, manual close/open trunk, sub-par acceleration- at least the transmission was good. Probably an ok choice for $349/month.

  12. I bought a 2018 Cadillac ATS luxury RWD model you claimed had multiple safety options such as lane change warnings. I bought it through EVO motors in Tampa, Fl the day after Thanksgiving 2019. N fact it has nothing but front and rear sensors. Do you stand by your advertisng?

    1. ATS and CT6 are different cars as such your question/statement is posted in the wrong place.

  13. Late to the party here, but this article says “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” but the article those words link to says “It is currently not clear if it plans to build the full-size luxury sedan at another one of its plants, or it will replace it with a different product sometime in the future.”

    So… which is it? Is GM going to cancel domestic sales of the CT6? Or just domestic production? Or has that not yet been made clear?

  14. I bought a 2018 CT6 Premium Luxury with Super Cruise Dec 6, 2018 and we absolutely Love It. It is head and shoulders above anything on the road today “that we test drove” Super cruise works flawlessly so far and is a true no hands driving system.
    There have been NO problems with the vehicle to date. Comfort and technology is second to none. That being said, when I tell people at the Poker Table I drive a CT-6 they are clueless or ask if it’s a Tesla? I have seen 1 or maybe 2 on the road in the past year and drive to Las Vegas from Arizona regularly. If I pass out going down the highway at 75 mph the vehicle technology will sense it, take control of vehicle, turn emergency flashers on, slow down & stop and call onstar for emergency help. This Full Size Luxury Sedan is the Best of the Best….. yet nobody has heard of it!!

    1. Consumer reports does not list the 2018 CT6 in its used car recommendations either good or bad, It’s like it doesn’t exist…….

  15. I own a 2019 CT6 and I really like it. Though after struggling with two 2017 CT6’s with the troublesome and crude 8 speed transmission, I can see why this model was doomed from the start. 2016-2018 CT6’s did little to inspire consumer confidence. The new 10 speed transmission and the refreshed design in the 2019/20 version really proved what this model could have been. What an unfortunate blunder.

    1. I have a ’17 Premium Luxury and have had zero mechanical issues! You’re scaring me, lol.

      1. Where to start…. perhaps it was a weird coincidence but the combined failures in my new 2017’s included rear hub/transaxle failure before 1000 miles, door/front fender misalignment requiring 2 weeks in the body shop, and the final straw: constant re-learning for the disasterous 8L45 transmission which never shifted properly. The new vehicle was gutted when the transmission finally failed, then rebuilt with a new transmission that was just as bad. Both ended up back at GM. So far, my nice new 2019 has been trouble-free (shifts like a normal car, doors open and close and rear wheels have not fallen off). The 2019/20 refresh, as described in this article, has been an excellent upgrade for this very attractive sedan.

        1. Not sure if that means it was built on Friday evening or Monday morning. Guess it just shows that bad things can coalesce on any production line. GM/Cadillac has lost this car buyer since battery operated cars prevents longer distance driving and I don’t want a utility vehicle.

          Reply
          1. Well, Friday and Monday cars may have some quality control issues, but that awful 8 speed transmission was installed Monday through Friday for three years of CT6 production.

            The 10 speed transmission in the 2019/20 CT6 is great.
