The M suspension does make a bit of a difference, i mean you can even feel the difference just driving it normally. An E36 with a well matched springs/shocks can already waste standard cars out there. No idea why the above Aussie results seem to favour the S4 so much, maybe the guy can only drive awd?
I don't dispute the M suspension and tuning would make a positive difference - it just doesn't appear to materially help the 335i against the new S4 (with LSD) on the track.
I also don't think the Aussie result is an anomaly. I have read at least 3 different comparisons from different parts of the world and all of them have the S4 beating the 335i (RWD and Xdrive) with or without M tuning, by a very considerable margin.
The S4's adaptive damping and LSD appear to be a major factor to the S4 supremacy with the help of a few extra horsepower. Since these pieces of tech are not currently available on the 335i, it would be very interesting to see the result of a comparison of an S4 without the damping and LSD.
Any opinions?
