Also, if I am not mistaken, the new A4 has an adjustable suspension similar to the M3. Its a good bet that the A5/S5 will get this at some point soon also.
Funny you should say that, as on some Audi sites there is a rumour going around that the S4 will receive not the v8 from the S5 but an entirely new engine, a v6 Bi-turbo no less. If that happens does this mean the S5 will change to the same or possibly keep the v8 but get Audi's new ValveLift technology to squeeze an extra few horses out of the old girl. The technology is meant to not only increase economy but aid power and torque to the tune of 8~10%, that would be equal to 385~390hp and 350ft/lbs of torque, not to far off what the M3 is producing now and well ahead on it's main rival, the 335i.
