Look, I am not going to discuss the 1 series as it isn't available in the US and I have no experience with it. Plus when discussing performance BMW's, the 1 series is rarely what is brought up in the first place.
The RS4 being quicker than the M5 or M6? Crazy talk, the only tracks where the RS4 can hang with the M5 have to be extremely tight. The RS4 doesn't exactly have a weight advantage over the M6 either and both of the M's are better balanced.
The top gear track is WET! I sure hope an AWD car beats a RWD car on a wet course. The S4 isn't coming near an M3 on a track. I had an M3, I'm not quoting numbers from Top Gear, I know this first hand as does anyone who has ever been on a track with an B6/B7 S4 and an E46 M3. I won't even get into the CSL.
Steering feel is overrated? What are you talking about? What do you think the point of paying the big bucks for a porsche is? You know what the car is doing at all times, and steering feel inspires confidence. I sure can push a car harder when I have great feedback. I would say steering feel is of extreme importance in a sports car.
I can't wait for the E90 M3 to come out to once again set things straight.
