As I have owned a WRX 3 AWD DSM's and messed with an Evo or two, I will say the Subaru AWD is pretty amazing especially when it comes to their high end vehicles. And of course the Lancer Evolution's tech is amazing. I really cant say too much about Audi as I have never owned one, but it was weird seeing that guy lose traction like that. I know I said my top choice is from Mitsu but damn gotta give credit where credit is due, Subaru and Audi know whats up. I have read some stuff on the ATESSA drivetrain and it seems to fall into the "legendary" catagory. Oh and yeah, insurance in AZ. is ridiculous! I love it here in CO. where you get discounts for the AWD feature.
If you talk the talk, you better crankwalk the walk.
