The car swung around and the driverside rear hit the wall with enough force to break a forged aluminum wheel off.
I am not saying it did not HIT hard; you can tell by the bent roof that even the frame bent... What I am saying is that it did not LOOK that bad, at least compared to the Ferrari/Toyota one, where the Toyota actually flew through the air and hit head on into the barrier (which, of course, helps dampen the blow) and the Ferrari ended up on its roof.
I still have no idea how the Aston lost control, though; there does not seem to be any contact with the car behind it, it seems it just slipped out of control... Maybe the the wheel broke/bent before the crash?
