Word on the street is that the next-gen Cadillac CTS-V, due as a 2014 model, will retain its force-fed powerplant but its design will be based on the modern 6.2-liter LT1 that will find a home under the hood of the new Corvette. General Motors is reportedly working on two variants of the engine, one supercharged and the other with twin turbochargers – one of the engines will serve duty in the upcoming CTS-V and the brand's upcoming rear-wheel drive flagship. Expect the engine, regardless of its intake method, to make more power than the current powerplant (a 6.2-liter V8 with an Eaton Twin Vortices Series supercharger developing 556 horsepower and 551 pound-feet of torque), but with improved efficiency.

The ATS-V, still officially unannounced, will reportedly get a twin-turbocharged V6. That engine should be plenty powerful, but if consumers demand even more displacement there is room under the hood for something as large as a 7.0-liter V8, say reports. Wouldn't that be fun?

      Sounds good. An ATS-V with over 400hp from a bi- turbo V6 will go toe to toe with any premium sport C segment car in the world. The CTS-V should be V8 and a level above the ATS-V .

      I really hope they go with an LT1 in the ATS-V. I'm not completely opposed to the TT V6 idea, and it'd obviously be easier considering it already has the non-turbo version of the engine. But the idea of an ATS sized sedan with a snarling large displacement V8 makes me all giddy. I have never owned a GM vehicle, but if they release the ATS-V with an LT1, a manual, and a limited slip diff, that will almost certainly change, because that's exactly what I've been looking for. And hopefully this will finally force Ford into adding Ecoboost tech to the Coyote like it's been designed for since the beginning. I'm hoping we'll be see a 700 hp Ecoboost 5.0 GT500 taking on a 700 hp TT LT1 ZL1 in the near future :)

      If Cadillac can fit the 7.0L V8 into the ATS, then they should install it, while the car is still seen as fresh, rather than wait a few years when this generation of the ATS is on its death bed. Following Mercedes' "Black Series" of limited-edition cars as their model, Cadillac can maintain a level of excitement for all lines of their cars, not just the ATS. In another example, people may joke about all of the special editions of Mustangs that Ford produces, but those special editions kept the Mustang relevant and fresh in the eyes of the public for years and help maintain consistent sales numbers. Cadillac doesn't have to build a lot of 7.0L ATS models to help insure the car is seen as a viable alternative to its European competitors.

        People who don't consider it a viable alternative won't be convinced by a more potent engine. They are Europhiles. No amount of objective comparison or experiences with unreliable European cars will sway them.

      I sure hope they offer a manual trans option, or DSG option. The slush box pretty much takes these cars out of the running against the M3/M5

      I'm not apposed to a twin turbo V6 in the ATS, provided it sounds good. It's no secret that the ATS was designed to be able to hold a big V8 though. I think a TT V6 in the ATS-V and maybe eventually some sort of uber ATS-V with a big V8 would be a real winner.

      I hope they keep these cars RWD but offer manual trannys and DSG. The twin turbo V6 could also be put in a Buick Regal and create a GNX and have it AWD only so it would not step on the Caddy\'s toes or the Chevorlet SS which is RWD and a non turbo V8 and a regular 6 speed auto. Lots of potential here to have a few flavors of hot performance sedans :)

      If the twin turbo six does get green lighted in the ATS-V, then I would be interested to see if it will be the only GM vehicle to get it.

        Yep. The TT V6 appears to be a mid-level model, above the V6 and below the CTS-V.

      Twin turbo V6 for the ATS-V makes sense, but the hooligan in me wants an N/A V8 for dat throttle response. Another supercharged V8 for the CTS-V makes sense.

        This won't be your Grandma's Cadillac dude. If she does get one of these then, from an auto enthusiast's standpoint, I'd have a whole new respect for her. She'd be the modern day "Little Old Lady from Pasadena" in my mind. Anyway, I have a sneaking suspicion that the majority of people buying these new will be men between the ages of 45 and 65.

      Wow that's stupid. Why would they develop the ATS to hold a V8??? Sure it's cool but are they deliberately trying to undermine the CTS-V? I think if they ever offer the ATS with the same engine/power levels as the CTS-V, they might as well cancel the CTS-V. There has to be a reason for the CTS-V to be more expensive than the ATS-V -- a couple of extra inches of rearseat legroom and trunk space is not enough.

        Tell that to the Benz guys who didn't have a problem having all of their top-end models having some variant of the 6.2 AMG V8 under the hood at one point.

        Valid comments from all. I guess I don't want GM to confuse people. Which is the real enthusiast sedan -- ATS-V, CTS-V or Chevy SS? If the goal is ultimate performance, then yes a V8 ATS-V is the way to do it. I think they would be wiser to show some restraint instead of catering to their 'legacy' interests that always clamor for a V8.

        First off, small blocks fit in just about everything, so I doubt they really had to try to make the ATS fit around it. Second, who says it's the same engine? I think it's pretty obvious that the ATS would get a normally aspirated V8 and the CTS a Forced Induction one.

        The ATS is more than likely not getting a V8, especially with the M3 getting a 6.. all they said was there's room under the hood for a V8.

        Because the CTS-V is going to be larger and produce a LOT more power. I'd be very surprised if the ATS-V cracks the 500 hp barrier, and I'd guess it to be more in the 450 range. The current CTS-V already beats that by 100 hp and torque, and the new engine is going to make more than that. I'd be surprised if it made less than 600 hp in its next iteration. So you have a distinct size and power difference giving all the separation you could want. The ATS-V is very clearly targeted at the upcoming M4 and the C63 AMG. The CTS-V is going more for the M5/E63 AMG/S6 crowd.

        It's really not stupid, the CTS/CTS-V was always a "tweener" car between the C/3/A4 and the E/5/A6, and so yes, based on the current CTS/CTS-V, there's only "a couple of extra inches". The new CTS/CTS-V however is supposed to grow substantially and move completely into the midsize luxury field...think of the size difference between a C and E-Class, or a 3 and 5-Series. The ATS/ATS-V is a compact luxury vehicle designed to compete with the C/3/A4 in every category, the CTS/CTS-V isn't. The CTS is also about 400lbs heavier than the ATS, and there's no indication it's going to shrink significantly in weight (despite moving to an enlarged Alpha platform) so the "power levels" will make a huge difference. The design of the ATS also started several years ago pre-GM bankruptcy and before the new CAFE regulations and current fuel prices, so it was designed to hold a V8.

      It's already known that the ATS cannot accommodate a V8. Also the "word on the street" about a 2014 CTS-V can't be right either since the new CTS has not even been launched. It's always 1 year later (or more) for the V. There's also no way they are working on 2 different V8 configurations it would be a huge waste of money. Maybe caddy was thinking of 2 possibilities at first but they would only develop 1 of those for production. The smart money is on the same setup as corvette.

        You speak so matter of factly, but yet the Platform this car is based on underpins the next gen Camaro as well. So I would wager that a V8 will fit just fine under the hood of the ATS, especially a pushrod V8 keeping mass low and reducing overall height of the engine package. And two forced induction variants of the all new LT1 makes total sense as well, as it serves different purposes for different cars. GM did the same thing with the 2.0L ecotec first a supercharger and then the move to a turbo setup. I can definetly see the next gen ZR1 being twin turbo as opposed to the supercharger. In respect to the CTS, just because a vehicle hasnt been launched, doesnt mean its future isnt being planned as we speak...

          Psyclist, The next CTS will be on a stretched version of Alpha, so, should the Camaro be based on the stretched version, then, yes, a V8 should fit fine. However, if you're looking for an ATS-sized Alpha car with a V8, I don't see that happening. The product specialist lady at the auto show told me that the V8 won't fit under the ATS' hood, and I think they'd rather stay hush on the matter than lie about it, if, in fact, it COULD fit.

          A DOHC V6 is taller than a pushrod V8. If the V6 can fit under the hood, a small-block V8 can too. The only dimension where the V8 is larger is in length (front to back). Since the platform was designed to accomodate V8s, I would assume the ATS could fit it.

        If you can fit a V8 into a Miata, you can fit one in the ATS.
