BMW vs Audi

[Porsche_Cayenne]

Maybe u have already talked about it, but I'm new here and I'd like to hear your opinions about this...

Seeing motors-look/image of Audi and BMW, which of these is the best (... sorry for my english....) ?
I think BMW has got a look very younger (3 series) and "sprinter...(!)" than Audi...
BMW's motors are most fast (I'm talking of 0-100 km/h too) than the Audi, right? Diesels too...
Anyway, here in italy a lot of people says that Audi rulez.... what do u think?

ciao
