I know this first post is a bit old:

but considering the existence of the TT Ultra concept at Wörthersee:

it seems like a lot of the fancy weight reduction using "space age materials" is becoming a reality.

If they can shave over 600lbs off of a TT how much would come off the larger 4 platform? 800-900lbs? A next gen S4 at an even 3000lbs would be pretty awesome.

I'm pretty interested in that twin turbo 3 liter diesel they have in the SQ5 as well (313hp, 479lb-ft)

I still vividly recall reading an interview of a high ranking Audi official in 2005 about their future offerings, and a lightweight 3000# S4 to appear somewhere around 2015 using a 4-cyl HO engine. The interview was around 2005. Many in the b6/b7 S4 Forum in AW discussed future offerings from Audi. The b8 being one and what the official said would appear the the next S4 platform (b8) pretty much appeared mechanically exactly as he described. He then went on to offer the teaser about the future of the brand and what Audi needs to do to be 'green' and still be the best of the high-performance sedan segment.
I was laughed at and ridiculed when I posted it here.
I wish I would have saved the review because he laid out the groundwork for Audi future in that piece.

B8 S FOR

I am hearing that the B9 will be going Bi-Turbo Charged. Those are the rumors floating around and from Germany. Who knows ? ?

Maybe a twin scroll turbocharger?

the B9 S model should have something to keep up with the competion;

"AMG's version of the upcoming CLA compact sedan. Powered by a 355-hp, turbocharged 2.0-liter four-cylinder, the CLA45 AMG will charge to 60 mph in around 4.5 seconds and hit the governor at no less than 155 mph. An all-wheel-drive system will help to get the power to the ground. "

B8 S FOR

Possibly....or they slam the existing Bi-Turbo in the S6-S7-S8 into the new S4! Can you say ROCKET!!!!!!!!

That is the twin scroll turbocharger.

I would love Audi to do this, but it's probably not on the horizon. With more stringent CAFE (Corporate Average Fuel Economy) requirements coming soon, they aren't about to put a twin-turbo V8 in the S4. All of the auto manufacturers are moving toward smaller blown engines to try to generate HP, but keep EPA gas mileage up. Audi was sort of ahead of the curve by forgoing the previous V8 and going with a supercharged V6 for the current S4.

-True ..you make a valid point!

It is ridiculous what they are getting out of small engines now. I had a ton of fun shopping for my S4 but this next gen is going to be pretty awesome.
