It looks like Mercedes has one less AMG E63 to burn at their "AMG Challenge" events. We just received these two shots and the following anonymous tip:

"Just got confirmation that this vehicle was wrecked by a participant at an AMG Challenge event while at Cal Speedway this weekend in Fontana. Occured towards the end of the event when participants are permitted to "push the vehicle a bit more" with a right seat instructor riding shotgun. Word on the street via the participant is 160mph entering the turn, 130mph into the wall."
