    Cadillac ATS-V is probably getting a twin turbo 3.6 liter V6

    The ATS-V might not be getting a V8 or TT 3.0 after all. Now it looks like GM is favoring a twin turbo 3.6 liter V6. More displacement (over the 3.0) certainly doesn't bother me. What I wonder now is if it'll be a true twin turbo or a twin "scroll" turbo...

    The CTS and XTS will still be getting the 3.0 liter twin turbo V6 engine...

    Re: Cadillac ATS-V is probably getting a twin turbo 3.6 liter V6

    I was under the impression twin scroll turbos were more efficient. I would prefer to see a biturbo; a small turbo to prevent lag, and a big honkin turbo for that boost.

    If it's not a biturbo system, they better incorporate no-lift-shift with the manual, otherwise there will be no way to maintain boost.

    All things considered, I would still rather have an NA V8. But I would also like 30 mpg. Perhaps the ATS-V is not my next car.

    Since I'm much less of a fan of BMW's twin turbo rather than their single turbo, I hope Cadillac uses the twin turbo method. Then again, the Grand National was a good example of what can be done from a production single turbo. I just still have the twin turbo Supra, RX7 and 300ZX in my head... Oh, and the 335i.

    Sure hope you're correct about the 3.6. That extra 600 cc will be felt and appreciated.

    So, the discussion above is centered around the type of twin-turbo setup it would have. Personally, I think of a biturbo setup as being more complicated, and my money is on GM shying away from something like that for that very reason.

    A TT3.6. Interesting. 425 hp would be even more interesting.

    the twin K03 APB in the S4 had plenty of power everywhere. You don't need a sequential turbo engine these days. I would prefer a twin parallel style myself. Maybe even a scorpion sytle.

    personally, since I grew up with a TTV6, I wouldn't mind going back to one, espically if we're talking about 20+mpg combined or so. I have a feeling $5 Gas this summer will be pretty painful in the 15mpg V.

    The only turbo I have driven in the last 10 years is a GTI. It has one small turbo. It suffers from no lag that I could tell. But it also runs out of breath as it approaches redline. I understand these modern twin turbo systems are much better than the last one I drove (an old 90s Talon) But I will still need to drive one to set my mind at ease.

    I'm not happy. I'd prefer the V8.

    But if the next M3 is going this way (and all reports say it is) then you can't really fault them.

    exactly, I really hate to admit it too, but fuel economy is going to start to play a bigger role in sports sedans espically(since heavy cars+ big engines is always a bad recipie), and when people start to pay $100(which is only a few years away at this rate) to fill-up their LSA every 220 miles, people will get over a V8 real quick.

    Re: Cadillac ATS-V is probably getting a twin turbo 3.6 liter V6

    Personally, I like getting good fuel economy, but there's lot of oil ... TONS of it. Any scarcity is artificial. But, artificial or not, it's "real" if you can't pipe it in and you can't drill for and those that have it want to raise the price. Getting 30 MPG highway effortlessly and do 0-60 in under 5 sec plus pull in excess of 0.9 Gs around corners is a decent future all considered.

    Well, the LSA is extreme. The V1 and tall gearing could get mid-high 20s all day long. A turbo V6 will drink fuel just as quickly when flogged...

    It's when you're not flogging it that I care about.

    It'll have a pretty decent drag coefficient with a slightly smaller frontal area compared to a Gen 1 CTS (good for highway MPG), and the low weight will help with city MPG. With DI, VVT, and a small (vs a V8) displacement, 30 MPG hwy while not flogging would seem a cinch.

    30 is probably a pipe dream stock, but 25-27 is realistic, I could see 30 with big turbos.

    This is why a turbo V6 is a better choice, in my opinion. I've noticed that when driving a turbo V6 lightly all the time, I get noticeably better gas milage compared to driving a V8 lightly all the time. When driving aggressively, both are about the same. This brings me to the conclusion that a forced injected car will give you better gas mileage over the long run unless you're ALWAYS driving aggressively.

    I am getting 24 right now with my 4000lb 6.2L Camaro. If I work it, I can get 25. So a V6 ATS-V has to be better than 27.
