I wasn't aiming my post at you Peter, sorry if it came across that way.
I've heard numerous people already saying 'The RS4 will need a boost to keep up'..'the RS4 will be forgotten'....'will there be an RS4+' etc etc....just nonesense. Just like talk of the RS5 being nonesense given no one knows anything about it.
The figures are extremely close. I would imagine the M3 would be faster in a straight line and be more fun to drive round the track. Same case as always when it comes to 4WD Audi's S & RS cars and BMW's M cars. Different strokes for different folks.
I'd happily drive either, but to me the RS4 is just a far better looking car and that's why I'd choose it.
Here's some side by side comparisons if anyone is interested, interesting pics:
