    I'm talking about horizontal space. The V has a raised hood because it needs it for the supercharger. Presumably this thing is N/A and thus does not need the big hood. it's just a matter if they can wedge it into side rails that are smaller than the CTS's rails-- which are already a tight fit.

    Re: Cadillac ATS-V - Twin Turbo V6

    I would suspect the ATS will be at least as wide as a first gen CTS. It looks like it has a pretty decent stance. If the ATS-V gets an LS3, or whatever the next equivalent is, I would think there would be plenty of room. You wouldn't think there would be an FI V8 in the ATS-V. NA V8 or FI V6. Whatever happens, I hope they don't make it too expensive. I would really like to get back in a V in a few years.

    LS V8's are smaller than DOHC V6's in width & height. If taking the longest dimensions. So if you can fit an "LFX" V6 then you can fit an LS3. The Twin Turbo would be the widest engine.

    The small block is a compact engine, dense in stature, but overall dimensions are favorable. They fit in cars that housed straight 6's with minimal effort.

    I'd expect a high price. ATS has to start at $35k due to Buck Regal pricing. The V would be in the mid-50's at least I think.

    Keeps the riffraff out.


    As much as I like the LS3, it's inevitable that we're going to see the four-valve, overhead cam, smaller displacement motors replacing the cam-in-the-block motors in the future. Maybe the time hasn't quite come ... I don't know, but it's going to happen. With enough grunt, I'd welcome a V6TT ... as long as a manual trans was offered with it.

    Re: Cadillac ATS-V - Twin Turbo V6

    Lets not even consider acceptance of V6TT.
    Less power plus laggy response is a big step backwards.
    I'm really hoping for a DI LS engine to allow easy modding to 600HP NA.
    The smallest & lightest Cadillac needs to be able to deliver the best performance in the lineup.
    Let the bigger heavier Cadillacs pursue softer-gentler performance goals and target audience.

    You must not be paying attention to the V2 forum.

    Must not, I did not know the V2 was light, DI & NA.
    Is the ATS-V not supposed to be cool?

    What I meant is the the V2 is not "the bigger heavier Cadillac pursuing softer-gentler performance goals and target audience."

    I don't quite get it, but there are plenty of V2 pushing 700 whp. A DI NA LS V8 is not gonna get there.

    I don't see how a TT V6 vs a DI V8 has anything to do with the world changing. But if GM goes V6 on the ATS-V, what will definitely change is my interest in it. I'd love to see a 450+ V8 in a car smaller than the current CTS-V. Sort of a V1, but without all the dopey ergonomic and driveline quirks.

    performance is relative. Mercedes Audi and BMW all have small, fast track cars and then they have hugely powerful touring mid-sized cars that would murder said compacts In everything sans a race track. I'm with jimmy as well in that I'm not seeing 600na hp from a genv if we're only talking about adding d/I without extensive modification.

    The V2 is too heavy and I thought the 3rd Gen CTS was supposed to get even bigger.
    V2 gets its power boost from a SC, which has its drawbacks.
    DI would be a more efficient method of boosting power, that would work well in a lighter car.

    GM was guaging interest with a 470 HP DI NA LS and you guys dont want it????????

    Imagine the modding potential of an ATS-V with that engine?

    Re: Cadillac ATS-V - Twin Turbo V6

    The Germans put out an I6TT and with a boost tweak, the darn things scream.

    Why couldn't the same thing be done on an all aluminum V6TT (DI, of course)? ... something rated at 380-420 hp out of the factory going up to nearly 500 with mostly just a boost increase (plus a PCM tweak)?

    You'd have to give up the V8 exhaust note ... that'd be the down side.

    You're preaching to the choir here. I am all about na v8s. I have a camaro ss right now.

    I think we are just predicting it's more likely to be a turbo6. The ctsv already targets the m5 so it's only natural the atsv will target the m3. The next m3 will be a turbo6 (I think someone said this pretty much a lock). And an ls3 powered atsv would be like a repeat of the first gen ctsv.

    I would like to say I want a v8 atsv. But realistically I don't see myself buying another Cadillac. They are getting too expensive for me. My only option is to hope Cadillac resale stays poor and buy a 2 year old.

    a V8 would be nice, I just don't see a TT V6 as a disadvantage. people are still doubling or tripling the HP in B5 S4's with basicly a 20 year old 30V V6 design. It wouldn't shock me if that(500+) would be possible in a 3+L TT ATS-V with a tune and exhaust

    There is a local guy here with 2010 camaro v6. He is working with ips in Indiana and is already over 400 rwhp with his twin turbo setup. The goal is 450+ and he says they are almost there.
