    I didn't realize that I needed 556 hp when I bought my 2009 V2, but heck yes, I needed it. I agree that we need that slick TR6070, too, that's in the C7.

    If you want a high revver, a n/a v8 is in order.

    As the Maestro said; it's more fun to drive a slow car fast than a fast car slow.

    It's even more fun to drive a fast car fast. Unfortunately I don't have time for the track anymore.

    I see your point but this article about a BRZ that was given an LS2 transplant is food for thought regarding the weight issue. Granted an LS motor which are very compact. Swap only added 60 lbs.

    the S85 sucked with an OE exhaust in P400 mode, yes. Aftermarket stuff fixes that .

    You're welcome.
    Thank you^^^^

    Let me preface this by saying I'm not a huge fan of BMW's and very much dislike the stigma and pretense associated with them. My neighbor had an M5 that had an aftermarket exhaust some German name I don't remember. The nosey old coot self appointed neighborhood sentry that lived across the street hated it but I thought it sounded like pure evil. I loved hearing it pull into the neighborhood and out of the neighborhood. To date best and most unique sounding exhaust I've ever heard.

    Re: 4.5 V8TT engine

    I'm reading elsewhere that though the 4.5 V8TT was suppose to be under the hood of a GM concept vehicle (the Elmiraj), no one actually saw it.

    Other writings said it was somewhere in development within GM.

    Could be that this thing, if it exists, is a few years away which, if true, would make it unlikely to power to the new ATS-V which is expected to be available for the 2015 model year.

    Sounds like evil because the oil pump is having evil thoughts about stranding its owner

    Re: 4.5 V8TT engine

    Why would they put a better motor in the ATS-V and not CTS-V?

    Honestly, I'd be more than happy with that 420hp TT V6 that they put into the CTS-V....but then you have 3 different Cadi models with the same motor.

    Why they put that motor into the XTS or w/e I'll never understand...

    Re: 4.5 V8TT engine

    the 3.6L TTV6 is not in the CTS-V
    it is in the CTS V-Sport

    there's a difference (somewhat large difference)

    Re: 4.5 V8TT engine

    The first cts-v had a small block while the sts-v had a supercharged DOHC v8. There's no reason why they can't go n/a v8 in the ats-v and then add forced induction to the engine and drop it in the cts-v.

    Re: 4.5 V8TT engine

    ATS-V: TT V6
    CTS V-Sport: TT V6
    CTS-V: TT V8

    Done.

    Right because the 550i has a v8, the e550 has a v8, so cadillac put a v8 into the cts vsport. Oh wait..
