GM Developing Twin-Turbocharged V6 For Cadillac (Updated)

Rumor has it that General Motors has been tirelessly working on a pair of new twin-turbocharged V6 engines to bring about a new age of fuel economy and performance to its vehicles. As the stories go, the V6 engines are a familiar 3.0L and 3.6L in size. We’re here to report that this story is only half true. At least for The Wreath and Crest.

Contrary to other reports around the Interwebs, we have it on very good word that General Motors is not, and was not, developing a twin-turbocharged 3.0L V6 engine for Cadillac vehicles. Instead, all efforts are focused on the development of twin-turbocharging the popular 3.6L V6 that’s found in pretty much everything larger than a Chevy Cruze.

The goal of this engine is to offer the kind of horsepower we find in today’s 6.2L LS3 small-block V8 mill. That’s 430 horsepower, but we’ll give the window of 420-440 horsepower for the upcoming TT V6 for the sake of being optimistic. And because of the turbos, the torque band will be much broader and more available compared to a naturally aspirated V8. And because it has two less cylinders than a V8, there will be gains in fuel economy. We say that’s a pretty good heart for something such as, say, a Cadillac ATS-V.

  6. This, along with the 2.0T, should be able to cover every vehicle in GM’s lineup as a “premium” or “upscale” motor. Once GM adds DI to the 1.4T, these 3 engines should dominate the market. Leave naturally aspirated I-4s and V-6s as base engines, and high output small block V-8s as the premium engine for trucks and sports cars.

  7. Keep the turbos, I want a good old v8. I have over 200,000 on my sierra 1500 hd and that thing still runs as good as the day I bought it. The turbo engine will never smell 100,000. Beat that engine as hard as mine and it wont see 50,000

  9. How long until NASCAR changes the rules to only allow V6 Turbos?

  10. I disagree with some of the comments above. This engine should be solely used for Cadillac and Cadillac only, no other engine sharing. I actually think this would be great for the Cadillac Xts, it could use a bump in horespower. And, yeah, the ATS-V would also be great.

    1. I just think they should offer it on models higher than the Cruze because look at Ford.

  12. What a perfect fit for a new 2014 IMPALA SS , plenty of horsepower with decent fuel economy !

  13. what about that engine in a Corvette with AWD…

    Reply
    1. sure, as long as it’s not called a Corvette! 😉

  14. I’d like a new Monte Carlo SS, but I beg them please don’t make it into a coupe version of the Malibu. Way too many Malibu-alikes in Chevy’s lineup right now.

  15. I agree with Vic, this engine is perfect for the ATS and maybe my not so favorite XTS. With 8-speed Auto and & 7-speed Manual, now there is a good chance of good mpg returns with the ATS. Not to mention blinding performance that should woory the Germans, Japanese and Koreans

  16. Definiteley put that in the ATS. Maybe a Camaro, and i really woudlnt mind it in the Corvette. Just as long as its like a base model or something like that. Also I really hope they work on getting more power from that 1.4 L turbo, because the Sonic needs more power!

    1. I would like to see it availible in some 2013’s so i could get one this year for my next airboat project. I have a customer for it when the engine becomes avalible. Then we could save some fuel.
      Thanks, Chuck

  17. I’d have to agree with those that say that this needs to be in the half ton Silverados. 40% of all 2012 F150’s sold so far have been EcoBoost…

    Reply
  18. this is uncorrect i have personaly talked to a GM engineer and they are not going with the 3.6 it is a 3.0 turbo

    Reply
    1. If you read the whole story you would have noticed that we debunked the 3.0TT rumors and that GM is committed to the 3.6TT as its only TTV6.

      Reply
      1. I know for a fact that 3.0L engine is going into the 2016 Cadillac. There will be several variants, 2 with the 3.6L and 3 with 3.0L.
        3.0L LGW
        3.6L LGX
        3.6L LGX
        3.0L LGW
        3.0L LGW

  19. Could that TT be a mod I could do on my 2013 2LT RS, V6 Camaro?
