On my S6 test drive (which was exceedingly difficult to wrangle) I was able to dig in a bit, obviously no LC was used, and to my butt dyno the Dinan stage 2 and S6 feel very similar to me (perhaps a tad more hesitation in certain rpm ranges from the BMW). I would wager at the track the 1/4 mi times would be very similar, and on the street almost identical. I have a feeling the launch control would be used (at least by me, very seldom). I simply couldn't justify spending 10k more for the audi. If there was no wiggle room on the BMW, then I would have gotten the Audi. Both cars are wonderful, but unfortunately fall short of my 997.1 911 Turbo I sold. On the upside they both can fit my family of five.
Nice review but don't forget that the S6 will also be able to be tuned/chipped also then it will still be faster than the 550ix. Also the S6 has the sport diff which allows it to power through a turn rather than brake the inside wheels to accomplish the same as the S6.
The 550xi is a very very nice car but I would have to say that the S6 is positioned between the 550xi and the M5 more than a competitor if you look at the full performance of the vehicles.
