2009 Caddy CTS-V Getting 600hp Blue Devil Corvette Engine?


The 2009 Cadillac CTS-VLast month GM’s Vice Chairman “Maximum” Bob Lutz was derided by many including myself on this blog for making the comment about taking a look at producing a four door Corvette. Along comes the new issue of Motor Trend magazine which has a story about the next generation Cadillac CTS-V, which will have none other than a “detuned” version of the SuperCharged V8 Blue Devil Corvette engine under the hood. Could this be the first step in the evolution of a 4-door Corvette? The news is just another example of the ongoing horsepower wars and we think this is great news for GM as it continues to position the Cadillac against BMW, Mercedes-Benz and Lexus. However, the information from the Motor Trend article is not entirely correct:

What’s good for the Blue Devil is good for the Cadillac CTS-v. The next-generation muscle-Caddy, which is expected in the 2009 model year along with the quicker-than-Z06 Chevrolet Corvette, also will get the supercharged LS7 7.0-liter powerplant. While the Blue Devil, which will be named Z07, will have about 700-horsepower (“Trend,” June), expect the engine to be detuned somewhat for the CTS-v to about 600 horses.
The Blue Devil engine is expected to be the LS9 – a supercharged 6.2 Liter V8 that should produce upwards of 700 hp. It’s not a blown version of the current Z06 Corvette’s LS7 7.0 Liter V8. Others have speculated the Cadillac engine will have the supercharged LSA 6.2 liter V8. Both are supercharged variants of the new LS3 engine debuting in the 2008 Corvette later this year, but the LSA will have about 100 horses less than the LS9. Okay, now that I got that off my chest, let’s get back to the plans for the CTS-V. Motor Trend says the 4-door sedan will get an updated suspension with stiffer springs and shocks, Brembro Brakes and a host of exterior changes that will include front and rear spoilers and a mesh grille.

  1. i applaud for correcting motor trends obvious error about the LS9, correcting the LS7 supercharged, which we in the vette community and really they should know better, i emailed Rick conti, after he posted the same info, just stating what u did, about the LS9 being a new 6.2L supercharged engine, not an LS7 SC. we all know that the LS3, is really true base motor for the LS9. I still think that a 4-door corvette is not out of the air yet, making the caddys in the 70K region, put it up on par with the BMW 700 series, and the higher M series cars…i like the caddys, and the current CTS-V has more horses than the STS-V. correct me as well, that one of them has more HP than the XLR-V as well. reading the XLR forums is really something as compared to a vette forum.
    you do a great job and i have been reading ur site for about 2 years now. keep up the good work, and some of us really are glad u point out the detail you do, i am currently looking for a book about the corvette engines, for C2s, and C3s, the hayday of getting a true custom motor from the factory. I think we all get shortchanged these days, by only getting 1 motor choice, i think the Z51 option would be a great value with the LS7 eingine option, but as a Z06 owner, i am sure if would kill the value of the Z06, i just know if GM and detriot want to survive, engine choices dont make good business sense, too bad…i wonder and marvel over the engine configs of those C2s and C3s…even the LS6 454 having over 400HP in the day…i should be happy the vette is still being produced. i think some of styling cues of the late C1s, 58-62 would do well on modern vettes, those cars show class. No mustang can ever be called elegent…at least to me…
    thanks for platform and being a reliable source of my need for corvette news..

  2. Matt:

    Thanks for your comments, and for being a regular reader.

    I couldn’t believe how all these automotive websites, which have been following the development of the Blue Devil/SS repeated the Motor Trend supercharged LS7 story verbatium, when in every other story the engine was quoted as being the Supercharged 6.2L LS9. As I read the MT story the first time, I kept thinking that something is not right here and then it hit me they were talking about the wrong engine.

    I’m still not sure about the CTS-V using either a detuned LS9 or the LSA, so I am hoping someone can set me straight on that.

    I’ve said this before that the Corvette is the Halo car of General Motors and I think it can only help GM to have bits and pieces of Corvette technology scattered throughout the GM lineup. I hope the CTS-V lives up to the hype.

    Thanks again!
