V8 vs I6? One could say not fair, etc... But i won't bitch, although
my 
car has 2 turbos after all. Still the advantage of larger displacement and 8 cylinders is obvious (let alone Nm mark), especially above 100 km/h. And btw, that time 0-100 km/h for X5 (don't know about ML) seems lame, when factory time is 7.0. Of course depends on conditions and stuff, but i believe this car do better than that. Especially if it was equipped with M Sp.
But according AMS, X5 has better steering, better handling, is more sporty, almost equally fast... For me it also has better interior/quality feel (since i've sat in both on those and examined carefully, didn't drove ML though) and looks 10 times better inside and outside (
). And the fact that MB needs V8 to compete with this engine from BMW... All those are the reasons why X5 3.0sd is definitely my choice from this test... And my next car too.
