Finally had the chance today to experience the capability of an e53 in the snow! I must say I am highly impressed.
Braking is "normal". Antilock kicks in like any other vehicle would.
Turning is awesome. I can feel and hear the whole system reacting. A couple times I tried to pitch it sideways coming out of a turn and the X stopped me from trying! Yes it has some under steer, but at slower speeds it will corect that. This vehicle totally straighten up and proceeded forward. The whole time I'm trying to make it spin out!
Acceleration was insane. I started at the bottom of a hill and pegged the throttle just to see. The X simple clawed it's way up hardly breaking a tire loose. Very impressed with the throttle control.
I then took it to an empty parking lot, turned off the traction control, and had some fun
I'm running perelli scorpions.
Just thought I'd share my impressions
