    Re: 323 horsepower V6 for the Cadillac ATS

    I'm not a big deal.

    If the premise of this thread is true, then the ATS-V should have significantly (substantially?) more than 323 hp.

    Now, that's a big deal.

    The ATS-V will have at least somewhere around 400 horsepower or so.

    If it's going to weigh 4000 lbs, then it needs to be about 450hp. And it better have a nice flat torque curve. Not a mountain like the 5.0.

    I'm sure the ATS-V will be at least competitive with the M3.

    Re: 323 horsepower V6 for the Cadillac ATS

    The real distinction between the 335i and the M3 lies mostly in the suspension and the way the engines make their power. BMW did muddy the waters
    with the 335 since it can be easy to drive auto, tuned and get M3 performance. Latest info on BMW though is they are talking going back to 4 cylinder engines
    with forced induction. (Not for hi po cars though)
    I am waiting for the ATS to come out. I have 4 older E36 BMW that I have rebuilt as a hobby. (Cheap to work on, parts available everywhere)
    I note that these little cars handle incredibly well. I have an 1997 M3 auto that I rebuilt the suspension on and it corners as good as or better than my 2006 V!
    (Mostly due to the 3000 pounds versus 4000 pounds V)
    I hope the ATS will be lighter than my V by a good bit or else why would I want one?

According to folks here, no one has cracked the PCM in the CTS yet. I have never gotten anyone to confirm this. I don't know what differences there are, if any, between the PCM in the CTS versus the Camaro.

    If anyone has had their LLT CTS tuned, they are not posting about it. Since rumours seem strong about a twin turbo 3.0 DI, I doubt much progress is going to be made on aftermarket supercharging for the 3.6. There won't be enough demand for it. And without that, what point is there in tuning the 3.6? In the case of the Camaro (whose owners are far more likely to mod than CTS or ATS owners), you can go from an LT to an SS for about $8000. A decent supercharger setup for the LT is going to cost far more than that.

    I have been getting a solid 25 mpg gallon with the SS. There is no way a supercharged LLT is going to do better. So there is no feasibility to doing it. I was getting 27-28 with the LT. Add all the weight and losses of a supercharger, 25 sounds about right. And it still won't have the low end grunt that the LS3 has. The only reason I can think of to do a supercharged 3.6 would be for lower insurance. Anyone looking to save a few bucks on insurance is not going to have the cash to upgrade performance.

    Just my $0.02.


    I Respectfully disagree that a blower (centrifugal, roots, twin screw, etc.) wouldn't be feasible or worth it. I had an A4 C5 with a Vortech V2 S-trim centrifugal that made around 575 to the wheels and it got better mileage AFTER the blower (15-23 city, depending on the weight of my right foot 28-30 hwy). This was because I had the tune spot on the money and the engine was more efficient.
    I have to disagree with anyone that says a tune is only worth it on a car that has been modded. The OEM manufacturer has too many restraints on it to maximize the tune. They have to worry about noise, emissions, driveability (which mine was also better AFTER the tune) and other stuff. I didn't need to worry about that stuff and just tuned it to drive and perform better......and it did. Just my .02 and you get what you pay for.

    They also have to worry about longevity so they can warranty an engine for 100000 miles, hence the conservative tunes. I see a correlation on these forums between tuning and things under the hood breaking.

    It's a known fact that many, many staff members at the major car magazines drive BMW's. There is of course two ways to interpret that. But there's definitely bias. I mean, the damn CTS V coupe lost in a comparo to the M3 because of its "BAD" automatic trans, when it beat it in every single other category. That alone speaks volumes.

    Depends how you look at it. 70000 is MORE then what they offered in 2006.

    Re: 323 horsepower V6 for the Cadillac ATS

    well they're increasing the time limit from 5 years to 6 years on the powertrain warranty

    this has been discussed ad nauseum in another recent thread

    the best explanation that i can come up with is that Cadillac new car purchasers main complaint with the warranty was that they ran out of time way before they came close to exceeding the mileage
    that and the competition (lexus, acura) offer a 6yr/70k powertrain warranty

    if you look up average miles driven per year statistics you'll see that for most people drive about 13K miles per year
    Owners of new Cadillacs probably drive 11k miles per year (on average)

    ...

    and in the end, it is what it is ...

    yeah, I wonder why that is...



    I would rather have the mileage than the years. I always hit the mileage limit first.

    Regardless, there is bias to a degree and it's extremely evident in their comparos.

    I agree. The bias was warranted years ago, but not anymore. If they cant give every car a fair chance, Im uninterested in reading or watching.
