Well "Grumpy" official Cadillac isn't saying whether or not the ATS-V's under hood space was designed for a V8 or not. Personally, I don't think it was. Now, a Gen V8 may fit and Heinricy indeed told me in the discussion he and I had back on the 14th that, if a twin-turbocharged V6 fits, a Gen 4 or 5 V8 will fit, too. As for the weight issue, I'm not sure what an LF4 weighs but the LS7 weighs 454-lbs.
One situation which makes me a little skeptical about the LS7 continuing beyond the 5th Gen Camaro Z28 which goes out of production soon or may even be out of production now, is that it's a Gen IV engine and I question GM's ability to continue making a Gen when all its engine manufacturing resources have moved to Gen 5. Plus LS7 is a port-injected engine. GM has gone totally to DGI with V8s. There are no direct-injected cylinder heads for LS7. While the LS7 is a great engine, it's reputation has been somewhat soiled by a problem with valve guide wear. I'm not sure Cadillac would want to put LS7 into a new brand and risk having to deal with that baggage.
That said, it's possible GM might justify a special small run of "ATS-V+s" because the small numbers might not affect the CAFE numbers that much. Might it be an "ATS-V+" with another 40-hp and carbon brakes? Might not sell very well, but it sure would make a hell of a performance statement. The question we need to ask: "Is that the type of performance statment Cadillac wants to make."
But, MT's and our speculation, aside, here's what Dave Caldwell said when I asked him about whether or not a V8 was considered during the ATS-V's development.
Yes, certainly that was a question in the development process. We were heavily committed to the Twin Turbo, hence it's very existence in the first place (it is a Cadillac-exclusive engine, designed essentially for this car.) But sure, this was something discussed.
Our approach came down to a couple of simple factors:
1 - The Twin Turbo is exceptional. V-Series is about track-capable (from the factory) luxury cars, at the pinnacle of performance, delivered in a unique and exhilarating fashion. This engine in the ATS-V is superb at fulfilling that mission.
2 - So why not a V8? We have a car coming soon - CTS-V in August - that fulfills this desire splendidly! It will of course be a supercharged V8 with 640 hp, an arsenal of torque, etc.
We are expanding V-Series (and the whole of Cadillac) to appeal to a bit broader audience. So we did not want these two V-Series product lines to be too similar, covering the same exact territory. ATS-V gives us the opportunity to broaden V-Series by creating a slightly different performance characteristic. One car is a bit smaller, more accessible (relatively speaking) and agile. The big brother is a little bit larger, more elite. We like to say that ATS-V is "the scalpel" and CTS-V is "the sledgehammer."
Funnily enough, the measured performance of the two cars will be quite close. The Twin Turbo does not dilute the V-Series standard whatsoever - I'd even say it adds to and enhances the V-Series toolbox. The car is extremely capable, superbly quick, such that we're pleased to put it up against absolutely every car in its category.
We at Cadillac will be among the few in the industry who will continue to develop and deploy new V8s in the future. So we, of course, adore the V8 engine, which Cadillac virtually invented as a mass-produced engine 101 years ago!
I also asked Dave to comment specifically on the story on the Motor Trend web site's "Wide Open Throttle" page. His reply was pretty pointed.
Let me know what you guys think about Caldwell's answer.That story is not accurate. We are not doing a V8 in that car.
MT knows this...
