In looking for more information on the traction control system I found the following:
Demonstrates single wheel traction of Audi, Mercedes and BMW
Compares Audi to BMW (Audi Fail - moderatly)
or
An Audi answer to BMW (BMW Fail - completely)
Of course ... can you really trust any of the videos ... in forum for the last video there is a lot of "discussion" about whether the car tire and ESP configurations were "really" the same and speculates it was a fix ...
I didn't find any videos for a similar test on the Evoque ...
It would be nice to find some truly objective video comparisons ... all of this stuff smells.
And for some reason I can never be sure if its an X1 or X3 I am looking at ... sounds odd ... I wonder if the dealer will enjoy that at my expense when it comes to collect my de-badged X3 ...
