i voted 2WD as i own one
i've had mine 1 year and a half now, i went from a 130bhp 2.0 Fiesta Si to my Saph so was my 1st RWD car
i dont drive mine that hard as i'm still learning about the car


so its not really caught me out properly yet
i've had the odd moment doing 70mph and it wanting to go into another lane

and it would spin up in 5th in the wet when it came on boost

but i put that down to the shite tires i had on as i was using some temp wheels
i had P7000's on my RS7's, traction was an issue when gunning it in 1st,2nd and some of 3rd gear but had grip from then on and hadno traction issues in 5th in the wet with these
i have been giving it a few more beans lately and had some sideways action when launching off from traffic lights
cant comment on a 4x4 tho as i've not driven one to compare it to my 2WD
