    3.0 Liter Twin Turbo LF3 V6 Engine [DELAYED]

    Unfortunately, the introduction of this engine has been delayed due to various issues. It was originally supposed to be available for the release of the XTS. Since we now won't be seeing this engine until late 2013, it'll also miss the introduction of the ATS.

    Cadillac isn't having much good turbo luck so far.

    If this is becuase there are quality issues, or performance issues, Im fine with them postponing its introduction to ensure a good product. That being said, the longer they wait to release it, the better and more advanced the competition will be, meaning itll have to be better to compete well.

    Is this engine the same engine that the SRX had until this year?

    No, but they are the same family of engines.

    The engine we're talking about here has over 400 horsepower.

    I'd rather them delay it for quality control purposes than rush it to market only to be a huge headache.

    +1.. the 'push a crap product out to make money now and fix it later' theme was one of the factors that ruined GM.

    I'd be willing to bet that the LS3 in the Corvette is almost as green (in terms of overall MPG) as the 3.0 Turbo I-6 in the BMW's...

    Re: 3.0 Liter Twin Turbo LF3 V6 Engine DELAYED

    it's a power delivery issue I'm sure. It's the same old reason GM hasen't been keen on the LSX or SBC in Cadillac's for the last 2 decades; power delivery just isn't smooth.

    I'd be willing to bet that the LS3 in the Corvette is almost as green (in terms of overall MPG) as the 3.0 Turbo I-6 in the BMW's...
    I'm sure the N54/N55 would fair better if it were also in a 3200lb coupe.

    That's crazy. The flat, smooth, torque curve of a pushrod V8 is a smooth as you can get. Loads of low-end torque. An ideal engine for Cadillac.

    So the Northstar was a fantastic waste of resources then? SBC's that I know of-- make peak torque around 3500-4000rpms. A Twin Turbo V6 or Turbo I4 typically makes peak between 1500 and 2000 rpms, *and* we're talking about 280-380ft/lbs of it.
