    And how much more nm can the new 7 speed S-Tronic handle?



    Likely not very much. It will use a V6 with displacement down at 3.0L with a Roots blower compressor/supercharger.

    Re: New Audi S4

    Interesting graph.

    Re: New Audi S4

    Ron,
    Something is wrong with your graph since new S4 engine is producing the same torque as S5 V8 engine-440Nm. This is NO value comparison between old S4 and new S4. Comparison should be between new S4 and S5 engines.

    Re: New Audi S4

    That graph looks quite strange as Kreso says, what's the source?

    Here's the official graph for the S4, I'm quite surprised that max torque doesn't arrive until 2900 rpm, I thought the whole point of a supercharger was loads of torque from low rpm. As a comparison the (technically inferior, according to Audi) twin-turbo 335i has max torque from 1300 rpm

    Ron's graph is plotted on the Y-axis for torque in British standard units (pound force-feet) rather than in metric (Nm), thus peak torque for the new S4 engine is 440 X .7376 = 325 lb-ft. He was merely comparing curves between old and new S4 powerplants plotted in horsepower and pound-foot units.

    Power is artificially limited to 245kw by the looks of it. Why?

    Kreso may be able to more accurately answer this one, but I speculate that the torque cap is to stay below the tranny's safety margin and the HP cap is to stay below the engine's safety margin, possibly through a combination of ECU programming of the supercharger and perhaps a wastegate valve?

    Your description is pretty good.
    All in all there is no big playground for tuning this engine-upper limit is at 360hp/500Nm...

    Am i the only one who thinks that they took the flame-surfaced/scalloped side panels off a BMW 1-series and the seats from a pre-MY'08 Aston V8 Vantage?!

    I had an Alfa in '02 and they already did look like that. They all borrowed from them.

    The image is a 2002 Alfa 147 GTA.
