i hear to much doubting of the x. i wouldnt do anything with nothing less then a .6 or .8 but i can assure you my x5 has taken plenty of cars on a highway roll. there is no comparison with the weight of the x off the line so thats foolish to even try. BUT at a 40mph roll in shift mode you have a good shot.
