I don't think there is any doubt that the RS5 is A) a great car and very fun to drive; and B) very close performance wise to the M3. The inherent problem with the A4/S4/;RS4 and A5/S5/RS5 platforms is that so much weight is ahead of the front axle. As the overwhelming test results show, that is an inherent problem that hurts Audi every time against a more dynamically-balanced car like the M3.
Even Quattro, as technologically great of a system as it is, cannot repeal the laws of physics (and why, once again, for whatever Audi gains with Quattro (great all-weather handling), it loses with handling (greater tendancy for understeer, less ability to perform sudden directional changes/slalom, etc.).
This is exactly why a lot of people were skeptical of the RS5's ability to out-perform the M3 even before it came out...
