All of my cars have a spring-pressure ball mount on the mirror for this reason. Maybe this is an indication of the forces behind this test, as opposed to what GasDoc experienced.

I looked at several other side impact videos from NHTSA and didn't see any mirror detachments. Someone should ask Tesla if this is intentional or not. Any potential fix would not be difficult, and would probably involve more or different glue.

Detaching under stress is a requirement. See page 30 in this document: http://www.nhtsa.gov/DOT/NHTSA/Vehicle%20Safety/Test%20Procedures/Associated%20Files/TP-111-V00.pdf
The question, I guess, is if the mirror detached well below the requirement of a 90 pound load. Given the body's rigidity in side impact compared to other cars, it would not surprise me if the stress at the mirror is higher than comparable cars.

Very interesting. Thanks for the link. Looks like the test procedure for mirror breakaway compliance is pretty comprehensive.
Just to confirm MPT - this was posted by nkinkaid (who authors all the bulletin board posts) on the Tesla Motors forum:
nkinkaid@teslam... | AUGUST 8, 2013
Tesla and NHTSA confirm that significant lifting of the second row seat pan upon impact as seen in the video of NCAP frontal crash testing is not a normal occurrence on Model S. Instead, this anomaly is due to the placement and installation of sensors, cables, cameras and other test equipment used to document the NCAP testing. During this process, the test facility partially removed the second row seat pan and did not fully reinstall it. This partial removal had no effect whatsoever on NHTSA’s NCAP test results. Normally, under non-testing conditions, the Model S second row seat is locked into place with a series of clips and fasteners. The second row seat pan will not lift in the event of a crash.

That impressed me too. I was surprised that (except for airbag deployment) there didn't seem to be any effect on the passenger compartment whatsoever. Would the car be considered as totaled, or repairable?
What is the speed on these tests?

Just in case Telsa's statement through MPT wasn't enough, or you're just curious what sorts of cabling and rigging go on with a crash test dummy (it's extensive), here are the relevant before and after photos from NHTSA:
Before:
After:
You can see the rear seat backs are still in their upright position after the crash, and the extent to which NHTSA had messed with the seat bottom cushion for cable rigging. I think we can put this concern to bed once and for all.

Wow, these are really fascinating photos. Thanks for posting.
I didn't know that testing equipment was so massive. Guess it has to be to withstand the enormous stresses induced by the crash.

Indeed. I assumed all necessary equipment was contained in the dummies themselves and monitored remotely. Either that or downloaded after the fact.
I imagine it would be difficult to fit all this into some test vehicles.

I found this article on the best ratings for rollovers. http://www.carsdirect.com/car-safety/top-4-best-rollover-rated-suvs
Ignore the text of the link, it does talk about the best in different classes.
The formerly best sedan had a rating at 9%.
The best sports car rating is 7%.
The Model S blows the them both away. While we knew it would, this confirmation is really stunning and could easily help sales if sales were not already production constrained

I agree. I don't think the mirror should break loose like that, but I can't say I know for sure. What I do recall are several incidents around here where people have been killed or seriously injured by things like flying cell phones and laptops when cars are involved in accidents. One example here.

Thanks to the folks that found and posted these.
What was the deal with rotating the car upside down on that rig? Was that just for visual inspection after the crash test?
Also, I've seen alluded to several times on the forum a "roof crush test" that was performed wherein the Model S was so strong it "broke" the testing machine? Has anybody knowlege of that first hand that can confirm... or better yet is there video of that around?
Thanks.
