The results: Excellent in every category. Roof, front, and side.
However, I am dissapointed that the although still rated "excellent," the F10's roof can only take 15,000 lbs before crushing a certain amount where the Hyundai Genesis can take 19,000 lbs and the Mercedes E-Class 20,000 lbs.

Also in the side-test, the E-Class roof structure didn't bend at all. (Same with the C-Class)-- a result which I've never seen any other car tested by the IIHS do-- I've yet to take a look at the technical measurements, will do so soon.
I'm not complaining, the new F10 is obviously an exceptionally safe car (the ratings prove it) but it seems Mercedes has edged BMW out in terms of body strength.
edit:
I took a look at the tech info. The F10 seems to have a slightly more stable passenger compartment in a frontal collision -- just barely and a somewhat stronger footwell. The dash and A-pillar both see ZERO movement after the crash. The mercedes saw some negative movement -- about 1 cm or so.
The E-Class's side structure, however, moved 5cm less towards the centerline of the steering wheel. This means you have 5 more CM of protection in the E-Class in a side collision!
