whats so strange in it? Comparisons like these are never going to end. You'll always see S class vs 7 Series etc etc. In the mentioned the video Audi is proven to be the better of two. Maybe in the next model of any of this class cars BMW comes on top. There's no line on stone that a specific Car maker is always better than the other( s )
By the ways what i'll like to see is BMW 3 series vs Audi S4 vs Mercedes C Class comparison.
