RE: B8 S4 turbo
What audi probably did is tune the car for more TORQUE and slightly less HP. Im pretty sure the HP figures are right on though it is an official release from audi. Regardless of power output the performance specs are better than the b7. Your average consumer dosnt even ask how much HP the car has. However assuming many potential S owners are in a slightly different demographic than your average buyer i figure if they has the smarts to do some home work on HP figures they are also interested in 0-60.
From audi world
"We have confirmed with inside sources that the B8 S4 will debut with a brand new 3.0-liter TFSI bi-turbo producing 330-hp. With this powerplant Audi can nearly match the B7's 340-hp output while providing even better performance figures. Manufacturer published (conservative) 0-60mph drops from 5.4 seconds to very low 5's, while the accompanying combined fuel economy rises from 17 mpg to over 20 mpg."

RE: B8 S4 turbo
damn that thing is sick looking..but wheres the badges?? debadged??
now for davidgotnaudi..the b6 and b7 have what 340 hp..the b5 has 250 stock put a chip on it that adds 60 so 310 put a catback adds 30+ hp so thats right about the same hp then it goes to weight the b5 is much lighter then the b6 or b7 so in my eyes stock the b6 b7 will win then once stg2- in the b5 you will walk all over the b6 and b7 and when you go stg 3 just forget about it
thats why i wouldnt spend 50k on a b7 s4 when you can get a decent b5 for under 20 put 10 or 20 into it and it will be game over ..thats my 2 cents for all it matters

interesting reading.
interesting reading.
Those following the speculation and conjecture around the next generation S4 know that different powerplants have been reported by different publications.
AudiWorld has reported on a V6 twin-turbo configuration: http://forums.audiworld.com/blog/msgs/2175.phtml
Fourtitude has reported that it will instead be a supercharger:

Who's right?
In the short term it could be neither according to an off the record conversation we had today with somebody familiar with the development but not authorized to speak publicly.
The B8 S4 is very much previewed by the B8 S5, so much so in fact that it would be a breeze to take the S5's 4.2-liter FSI V8 and drop it straight into the S4. Having driven the S5 extensively we can tell you it is a more capable (and more fuel efficient) V8 than the current model S4 employs.
The biggest issue with continuing with a V8 is CO2 emissions. Based on current regulations manufacturers are essentially tested based on their entire fleet average. This of course takes into account the overall numbers of each vehicle sold. The S4 happens to sell more cars worldwide than most people would guess, meaning putting a V8 in it degrades the overall fleet average (whereas the S5 is much more of a niche vehicle and has less affect).
Audi has therefore explored smaller V6's for this important vehicle. Under a typical emissions testing environment a twin-turbo V6 tends to operate out of high boost for much of the time leading to very V6 like results. This is the best of both worlds - turbo charged power with V6 type emissions readings.
Audi also wants to differentiate between the S4 and the S5 from a powertrain perspective if possible. A V8 for the S5 and a bi-turbo V6 for the S4 makes a lot of sense from a marketing perspective.
So which will it be - turbos or charger? BOTH applications have been studied in depth, however the next generation V6 bi-turbo has been in development for 2.5+ years and is a refined and completely ready-to-go powerplant today, whereas the supercharger is far behind in the development cycle.
We believe that Audi's true preference is to go with a bi-turbo offering, but they are concerned about potential warranty costs having lived through the chip tuning years with the B5 S4's 2.7T. We further believe that a supercharged offering has strong support by a vocal few inside Audi, but no realistic chance of coming to market in this generation S4. Last we believe that it is not outside the realm of possibility that Audi will debut the B8 S4 with the S5's V8 under the hood. We hope it doesn't happen, and that we'll see the bi-turbo as previously reported by AudiWorld.
Timing is a whole different issue, and we admit that we were probably optimistic in our original article. It appears that the B8 S4 will not in fact go on sale alongside the B8 A4 in the fall, but rather will make a fall debut in glorious Paris. History buffs may recall that the B6 S4 debuted in Paris in 2002 and the B7 S4 in the fall of 2004.
