2020 Cadillac CT6 Soldiers On Without 3.0L Twin-Turbo V6 Engine

The 2020 Cadillac CT6 will not offer the 3.0-liter twin-turbo LGW V6 engine as it has in the past, the car’s order guide revealed.

Auto Verdict first reported on the engine’s disappearance this Saturday and noted the order guide only features two powerplants now. The first will be the entry-level engine, a 3.6-liter LGX V6 engine. The second will be the choice for those in search of more power, the 4.2-liter Blackwing V8 engine. Here, it’s detuned from the CT6-V levels to produce 500 horsepower and 533 pound-feet of torque.

The CT6-V gets a hotter Blackwing tune to produce 550 horsepower and 627 pound-feet of torque.

The 3.0-liter twin-turbo V6 bestowed drivers with 404 horsepower and 400 pound-feet of torque. With the engine’s demise from the CT6, it’s unclear where the engine may head next as the mill was only offered on Cadillac’s large sedan. The Cadillac CT4-V is a good guess, however. The luxury division will reveal both the CT4-V and CT5-V at an event on May 30th.

Without the twin-turbo V6, it makes for two engines gone from the CT6’s lineup. This month, we reported the 2.0-liter LSY turbocharged four-cylinder engine would also flee the coop. Cadillac never provided a reason for the end of 2.0-liter turbo-four availability.

In fact, the CT6 as a whole is in question. Cadillac’s “flagship” sedan was named as one of many passenger cars GM planned to cull from its portfolio. The car is currently built at the Detroit-Hamtramck assembly plant, which also handled Chevrolet Volt and Buick LaCrosse production. Both cars exited production earlier this year. GM plans to idle the plant in January 2020 while it builds Chevrolet Impala and Cadillac CT6 models a little while longer.

GM and Cadillac executives made things mysterious when they said GM is looking to relocate CT6 production to another U.S. plant. It could also be imported from China.

  1. Simply seems as though they went the 7Series route in offering only three engines. The 3.6L I really don’t get considering the smaller CT5 will have the 3.0LTT instead of the 3.6L. Its almost A$$ backwards, unless the strategy is to push more people into the Blackwing. As it stands.. the CT6 will have:

    335HP/284 lb-ft vs the 740 at 335HP/330lb-ft
    500HP/574 lb-ft vs 750 at 523HP/535 ft-lb
    550HP/627lb-ft vs the M760 having 600hp/627lb-ft

    In terms of performance.. Cadillac may make up for the lessor HP in some categories with the lighter weight and 10 speed

    1. BMW always underates their engines. So you should always keep in mind adding 10% to those numbers.

    2. The LGX 3.6 is coarse and gutless compared to BMW’s I6 turbo engines. Cadillac should have dropped it years ago in favor of the 3.0TT V6.

      I don’t understand how GM/Cadillac executives can have such a lackadaisical approach to cars. The entire rust belt economy depends on their business decisions yet even when they have the right powertrain literally sitting on the shelf they cannot put in the appropriate cars!

      The most charitable explanation I can think of is that GM executives are too lazy to bother driving any competitor vehicles. Every other explanation involves deliberate sabotage of GM’s auto sales.

  2. Wow, I stand corrected, Monolos (forgive my spelling) apologies to you but that leaves an ok v6 or a state-of-the-art V8…

    Reply
    1. No apologies necessary. LOL
      I am just so disheartened with how GM is treating Cadillac.
      I got so overly excited when they hired Johan. But GM did what GM does, cut Bait because the Bean-counters will never allow the Long Game. It is so disheartening.
      There is nothing wrong with the 3.6 HFV6 as a Corporate engine but it cannot hold a candle to BMW’s and Mercedes’ Inline Sixes and the Audi 3.0T. Cadillac spent money on developing the 3.0TT Specifically for the CT6 but this is how it ends up.

      Cadillac decided to build Tweener Sedans.
      So we get….
      CT4 – 1 Series Competitor
      CT5 – 3 Series Competitor
      CT6 – 5 Series Competitor
      I f GM wants us to believe that the CT6 is a 5 Series competitor they’re idea of going head to head with the 5 Series is to keep the Corporate 3.6 HFV6 in the lineup instead of the “So Called” Cadillac Specific 3.0TT which was actually developed for the CT6?
      Makes Zero sense!!!

      1. Can you explain why it “cant hold a candle” to the beemers an mercedes in line 6’s?
        just curious

        Reply
        1. Have you driven either one of them?
          There is a reason Johan pushed for “Cadillac Specific” engines. Why else do you think GM spent money on the 3.0TT?

  3. This is odd, depending on the pricing of the “base” Blackwing. Caddy really shouldn’t kill this car (again) – they’re getting rid of the XTS and the CT6 already sells well for its competitive set.

    I drove a CT6 with an LGW and simply loved the car.

    1. GM will simply reskin CT6 or, if reports are to be believed, move it to the new Alpha modular platform that can cover Omega size.

      GM probably wants the new design language on its flagship even though CT-5 has been universally panned. GM has makes the best concepts but it’s always thisclose to perfection missing the mark by cost cutting on the dumbest things.
      The car is intended to conquer Germany but will do battle with Lincoln which is Buick’s task.

      (GM wastes a lot a R&D for platforms that only last shot periods of time as they play catch up with Japanese and German companies. Meanwhile PSA uses common architectures with simplified parts and the 507 gets rave reviews!)

  4. Flip that 3.0 productoon over to the XT crossover lineup

    1. Sounds good to me!

  5. So we will see a 850nm badge at the back of this one?

    Reply
    1. Thats a good question, since they are pushing torque numbers in Nm as a badge.

      Reply
  6. My thought is that they’ll build a full year’s worth of cars in much less than a year to leave time to move the line elsewhere. Restricting the choices now means buyers won’t be upset later when the exact version they want isn’t available.

    Reply
  7. IMO. I think it is a big mistake.. like the article said that leaves a big gap between the standard 3.6 and the optional Blackwing. Both in price and Power. I would like to think the folks at Cadillac know what they are doing. But I have to admit sometimes they make me wonder.

    Reply
    1. All I can say is that my wife and I planned to shop the CT6 when her lease runs out in June on her CTS. The engine of choice was the 3.0TT – go figure! It bridged the gap nicely between the base V6 and new V8.

      Reply
  8. A quick look on the NADA guide website shows the price for the 2019 models including the platinum with the V8.

    Assuming you go for the “Platinum” trim and add the 20″ wheels (which is the only option on that trim as it’s fully loaded otherwise), here is what each engine will set you back:

    TT V6: $88,490
    TT V8: $97,490

    I don’t know about anyone else, but 9 grand is a lot to pay for an extra 2 cylinders and 96 more horsepower (Okay, you do get 174 more lb/ft of torque with the V8 but still). If Cadillac wants to make the V8 the only step-up option, they need to reduce the cost by at least 5 grand or more.

    Reply
  9. Perfect. That 2.0 was a disgrace. Looks like the new Caddy leadership is blasting in the right direction lately.

    Question: Why doesn’t this model come exclusively with the V8? The simplified design, manufacture and marketing costs could be passed on to me: future blackwing CT6 owner.

  11. Given the horsepower difference between the LGX and the 3.0-liter twin-turbo LGW V6 engine, it makes sense as the LGX twin-turbo 3.0L V6 should become the top engine in the CT4 and possibly the XT4.

    Reply
    1. In my mind it would have made total sense fro Cadillac to Completely Drop the Corporate V6 in favor of the “So Called” Cadillac specific 3.0TT. But I’m sure Johan and now Carlisle are told Zero Chance they get that kind of budget.

      Reply
      1. XT6 getting 3.6L V6 was a such disappointment. Might as well get GMC Acadia Denali. But I think they won’t be able to put tt engines in the XT6 because of the FWD platform.

  12. Insisto creó que la eliminación del motor 3.0 en el ct6 no es el mayor problema aquí Para mi va más allá
    El ct6 > M5 no lleva vida al menos que el 4.2 realmente genere 650 HP como mínimo
    El ct5 >M4 seria una buena competencia si utilizan el 4.2 el ct4 que nadie conoce de seguro Va con el 3.0 tt y esperemos que Sea con el motor ajustado a 460HP Ya que su competencia directa aun no es clara ya que el M1 o M2 son coupe y siempre llevan la delantera en potencia y en ser coches más ligeros

  13. Think the 3.0tt is going nowhere, will be regulated to CT4-CT5. The Blackwing would be in the CT6, Escalade and other big / fast Caddies.

  14. My initial reaction to reading the title of this article was “WHAT?!” This gem of an engine should not have been axed from the CT6 lineup. If anything, the Shove-It-Anywhere, peaky 3.6 should have been purged from the Cadillac lineup. Having a consistent displacement hierarchy seems to resonate with premium vehicle shoppers, such as BMW with its 2.0/3.0/4.4 engines. Whereas with Cadillac, the CT6 had 2.0/3.6/3.0, while it should be 2.0 PHEV/3.0/4.2 and those engines ONLY.
    It is so disheartening to see this brand being relegated to irrelevance after a few promising products were released, only to be cancelled or cost-cut into mediocrity (CTS Wagon and Coupe – V and non-V, first-gen SRX to name a few). Having the LGW as standard in the CT6, the XT5/6, and potentially in V versions of the CT4 and XT4 (think M340i or C43 AMG ‘lite’ models) would have allowed for SIGNIFICANTLY greater economies of scale, and would finally offer a LINEUP of Cadillac sedans and crossovers with EXCLUSIVE engines. Further perplexing is its inclusion in the CT5 lineup (CT5 550T), which was just recently revealed.
    But as usual, Machete Mary and the beancounters did not want that. It just seems like all GM under current management (or lack thereof) wants is to use the wrong-wheel drive C1XX platform, corporate 3.6 V6, and seriously subpar interior materials like there’s no tomorrow. The XT6 could have been something special, with the 3.0 and 4.2 coupled to the 10 speed on the Omega platform. But what we got was a warmed over, still undercooked Acadia with buzzword features and a seriously underwhelming interior. Most USB ports in class, anyone? LAME. The same applies to the XT5.
    While I long for the day when Cadillac topples the Germans, I find myself giving up hope. Lincoln seems to be ready to accept me with open arms in the form of excellent products (Aviator specifically) and far superior customer service. Even my former all GM family has jumped ship to other brands like BMW, Audi, and even FORD. Something needs to change soon, because originally Cadillac was favored to outlast Lincoln. Now, with the stunning Navigator, Aviator, and Corsair, Lincoln seems to have finally understood what their buyers seek in their products, while Cadillac is being subjected to cost cutting and mismanagement.. again.

    1. Lincoln don’t even offer a V8, rwd or (soon) a sedan, enjoy the faux Range-Rovers from Lincoln.

      1. I understand that Lincoln does not offer a V8, but personally I feel like the 3.0TT V6 found in some of their products is plenty of power for me (400-450 isn’t bad lol). While they are putting out impressive new models, their sedan lineup could use some updates. I think I read somewhere that the Aviator’s new RWD platform might be the basis for the next Continental and Zephyr (née MKZ). Don’t quote me on that one though. I don’t mind the Range Rover-esque designs they are putting out, as I find it more elegant than the XT6’s XC90/Atlas/Telluride influences. To each their own though! Hopefully the next generation Cadillac crossovers will migrate to the VSS-R architecture, my fingers are crossed!!

  16. No viene al caso nombrar a la escalade pero para lo siguiente las marcas alemanas por nombrar algunas ofrecen sistema 4×4 real en cambio Gm prefirió la plataforma del acadia barata y con un interior aburrido. Entones esperemos que la escalade sea adecuada Para 4×4 por favor ? y volviendo al tema deseo que llegue el 30 de mayo a Ver que nós ofrecen porque el ct5 es fijo un 4.2 Pero la incógnita es el ct4 y por favor hagan un esfuerzo con los motores casi utilizan un motor exclusivo Por modelo salvo el lsy

  17. I recently took delivery of a 2019 premium package MSRP 75290 includes 20 inch v spoke wheels. I test drove both the 3.6 and 3.0 TT I did fell a bit of a difference between the two engines but didn’t think it was worth the extra 12k to get the platinum edition.i looked at the sport model but didn’t like the choice interior colors. I got the Raven black with Sahara beige.After putting about 2k miles on the car I’m really glade I decided in the 3.6. The engine and 10 speed are smooth as silk and feel plenty of power from the 3.6

    Reply
  18. At least they did the smart thing by discontinuing the stupid 4 cylinder. I have to admit though that the 2.0L 4 was more powerful than the 4.6L V8 in my ’04 MERCURY GRAND MARQUIS but no 4 cylinder can ever be as smooth as a good old fashioned V8 or V6 so I don’t know why GM ever engineered that engine into the CT6 in the first place?
    The V8 is only offered in the premium sport version anyway so while the 3.0 is going away, the 3.6 should be more than capable in the standard versions in terms of smoothness and power.
    Personally, I think CADILLAC ought to have a car similar to the TOYOTA CENTURY. Now if any car represents what a classic American sedan ought to be like, take a look at it sometime.

  19. How about offering the 3.6 from the ATS Vas an intermediate engine.
    N/A 3.6 standard.
    3.6 TT 420 HP

    4.2TT 500HP
    4.2TT550 HP

  20. Steve Gold is complaining about platinum vs other trims, NOT appropriate. I agree the platinum is overpriced, but the 3.0 TT engine is terrific. I have it in the ’19 without the platinum and its the best engine/trans I have ever driven. 50 mile best mpg is 35. Power is great, trans is always in correct gear. The non magnetic shocks are great (I had mag shocks in a ’16 XTS). I won’t get the CT6 with the Blackwing V. I’ll have to look elsewhere after 20 years with Cadillac.
