After reading that article - if I had to bet on this (thankfully I don't
) - I would call it as I had said above. That is, I think the turbocharged/supercharged/whatever V6 will actually find its way into the A4 to replace the current naturally aspirated 3.2L V6. The S4, methinks, will share a powerplant with the S5, which is currently a 350hp FSI V8, but could easily be a more powerful V8 by the time the S4 launches.
