I guess thats the advantage of the 335d's diesel engine, the extra torque can takes advantage of the low final gear ratio 2.81, cant do that with the 2.0T. The 3.0T can take some advantage with its 325 ft/lb of torque using a final gear ratio of 3.09. The 2.0T has a final gear ratio of 3.76 I beleive. Transmissions are design for either gas or diesel engines, comparing the two is like comparing apples to oranges.

It seems like there are different versions of the 3.0T engine. The same engine but de-tuned? Not sure, you gurus probably will now

Do you know which one the Q5 will get? Q7 has this one:

HP:
280 hp @ 4920 RPM
Torque:
295 lb-ft. @ 2250 RPM

and the Q7S is rated at 333HP.

The current A6 has the base 3.0T (310hp/325ft.lb) and the S4 has one with a supercharger (333hp/325ft.lb.). The Q7 can be had with either, but based on that I would guess that they could put the 3.0T that is in the A6 in the Q5 as a replacement for the 3.2 and save the supercharger for a pumped up S model...or whatever they end up calling it. Who knows, but I think that might make sense.

The A6 and the S4 both have the same supercharged V6 in different states of tune. (Although performance numbers of the A6 have led to speculation that the engine's published HP is underrated.) Audi has confused the issue here by adding a "T" to a supercharged engine, when historically that would indicate a turbo. Audi defends the nomenclature by defining a supercharger as a "mechanical turbocharger."

Well, then I'll just shut my big mouth.
The spec comparison descriptions differ on the Audi site, listing the S4 with a "mechanical charger" and the A6 without. I thought that accounted for the power difference.

I think I'd take either.

The 3.0t is no doubt the more modern engine, 3.2 is history. Feg a5 lineup has both 3.0t and s5, so although it might be underrated, it still is no 333bhp. I myself would take the3.0 diesel w/245 bhp if it arrives there as rumors say, that engine is underrated!

I just heard from Audi Canada that the 3.0T won't be arriving until Q1 of 2013, so a 7-8month wait for me has become a 12-13 month wait... And I *will* wait.

I'd personally go for the 2.0T if I couldn't wait that long... not a fan of the 3.2.

OnAir77

As an owner of an S4 with the 3.0t engine, and having test-driven the Q5 with the 3.2, I would overwhelmingly recommend getting the 3.0t.
I will probably get one for myself when it comes out.

I would say anybody who is on the fence right now about the 2.0T and the 3.2 should wait, if at all possible, for the 3.0T Q5 before deciding. The 3.0T is leaps and bounds better the 3.2 in terms of performance and the reliability is a bit better as well, the power band of the 3.0T is simply incredible, definitely worth the wait.
