(First all, all the press releases so far have been regarding European engine choices)

But back in April, Fourtitude interviewed Audi of America's Director of Product Planning:

Fourtitude: Turbos have always been a big part of Audi's heritage - today, pretty much relegated to the 2.0T. You see BMW with a turbo mid-range, similar to offerings you have had in the past. Do turbos fit on the <u>top end</u> now, or is that more of something left to other technologies like FSI, valvelift, etc.

<b>Hoffmann [Audi AoA]: We haven't announced anything about that. But to answer shortly, yes. I think you will see something really exciting in the future with a <u>turbo</u>. Definitely.
</B>
Fourtitude: Will it be in the realistic realm, perhaps the B5 S4 or in the exotic realm like what the RS6 was in the past?

<b>Hoffmann[Audi AoA]: It will be in a more of a <u>high volume segment</u>. You will see something nice in the near future. That is all I can say at the moment.</b><ul><li><a href="http://www.fourtitude.com/news/publish/Features/article_3105.shtml">Conclusion: he is saying a new HIGH VOLUME TURBO engine (ie: A4?)</a></li></ul>

to compete against BMW's 305 horsepower.

They should just have two levels of turbo engines in the a4. A 2.0t with about 230hp to compete with the bmw 328i, lexus is250, c300, etc. And then a 3.0t to better compete with is350, 335i, g35, c350, etc. And bump up the s4's hp to around 360-370 or so, and give the rs4 about 450-470.

I guess the low torque output is to keep enough separation between that A4 3.2 turbo or biturbo and the V8 S4.

and replaced with a turbo V6 ~2010. The S4 and S5 will either get this turbo V6 or the RS4's high compression V8, with the new RS models getting a turbo V8.

I'd love to see that, but I doubt it.
