That engine is about to see its first debut in the revised Cadillac STS and also CTS, so it's quite possible it could migrate elsewhere.

There's nothing really to prevent it from doing so, aside from just getting it out in the Cadillacs first, and also seeing how it really does in comparison to the regular 3.6L as far as performance. That said, the other key possibility is that the DI 3.6L could just replace the regular 3.6L totally with time, but we'll see.

I would venture to say it's very likely in the drawing boards or idea stages for the Lambdas, particularly as they try to come up with new ways to improve power and performance without resorting to even larger displacements and more cylinders which just make the fuel economy fight that much harder to win.

As is, the current 275 hp 3.6L is an extremely good match for the Lambdas, and few do anything but praise it, but there always is that clamor for "more power". We'll just have to wait and see how GM handles it, and if they spread it around and how, or not.

Posted that question a few days ago on the Enclave site with the exact same thinking. I feel like computer purchasing just a little more of this and that and it will be perfect. Power/Torque=Engine, active head rests. Personnel link, keyless start.....you know how is goes

Interestingly enough, the current Cadillac CTS, Cadillac STS, Saturn Aura XR, and Pontiac G6 GTP all get 252-255 horsepower from General Motor's 3.6 liter V6.

In another discussion forum, someone asked how the Outlook and Acadia manage an extra 20 horsepower from essentially the same engine. The assumption was that General Motors made some sort of technological improvements for the Outlook and Acadia but did not make them available on the sedans. The response - which may or may not be nonsense (this is the Internet, after all :) ) is that the Outlook and Acadia engine do not have any sophisticated technological enhancements. What they have is a lot more room under the hood, so they can fit a much larger and more free-flowing intake and exhaust setup than you can fit in a sedan.

If that's accurate, then it stands to reason that a direct injection version of the 3.6 liter engine with the superior intake and exhaust setup on the Outlook and Acadia could make somewhat more than the 298 horsepower which the 2008 CTS and STS will have.

That makes sense. Look at the Outlook, it gains 5hp going from single to dual exhaust. The XE is rated 270hp and has the
single exhaust, and the XR and the Acadia are rated 275hp with the dual exhausts.
