If it really was a Moebius Loop, you would have to shift to negative G force and then back to positive G force. Something would be very seriously strange.
The report says it caught fire after he got out but in the video you can clearly see the fire started before the car came to rest. Thirty seconds later the flames filled the passenger compartment. It's a very good thing he escaped on his own. If he had needed to be rescued it would have been very bad.
Spectators are surprisingly and dangerously close.
They sure are! And they're general public, too. Had the stunt not resulted in a crash with injuries, or had not been videotaped for all the see, they might have gotten away without a citation. But you can bet the X Games folks will be getting one now. Chump change to them, but still out of their pocket.
Once their insurance carrier sees this I wouldn't want to pay their premium for next year. You couldn't buy enough liability insurance had that car exploded, or careened off to the right, and over those pitiful concrete barricades. They were very lucky this time (and so was Mattel, quite frankly, for simply being associated with the stunt - go from a shot of "Hot Wheels" to the car bouncing off the platform and into a bunch of people...real good PR on that one!).
'Not buyin' it. The video said the entry speed has to be between 48 and 52mph. If the structure isn't sound at 53 mph, it won't be at 52 mph, either. There has to be another reason.

They have to be able to take the jump at the right speed after exiting the loops, that is more critical!
If you just go fast enough to just stay on the top of the loop and are coasting then you pull 6g at the bottom (and 3g at the 3 and 9 o'clock positions). Simple mechanics question!
KE = 1/2 m v^2
centripetal force = m v^2 / r = 2 KE / r
PE = mgh, varies by 2mgr between top and bottom of loop.
It almost looks like they didn't compensate for the weight of the driver.
Is it true (from the comments on the first blog) these are Mitsubishi Lancer Evolution cars? From what I can see in other pics from the Web, the exhaust is on the right rear, which means the gas tank is toward the driver's side. Assuming enough gas in the tank to feed the fuel pump through the loop, and the weight of the driver, they should have used a couple hundred pounds of ballast on the passenger side.
Erco, next time volunteer to sit shotgun with the driver. Will make for a better landing, and a funnier video as you get out of the car at the end!
Had you entered your Corvair it would have lost suspension parts, too, and those *before* going into the loop.
At least the Hot Wheels stunt didn't shut down the whole of Los Angeles. I wonder how Ken Block pulled that off in $an Franci$co. WOW. And the sidewalks are deserted, too. Where did all the lookie-loos go?
At one point you catch a glimpse of the position of the Sun and it looks fairly low on the horizon. So I would guess that they filmed this early on a Summer morning. You would be surprised how deserted the streets are at 5:30 AM. The movie "28 Days Later" used that technique to film in an empty London.

Possibly to avoid an infinite loop?
...H*ly Cr@p!!!!!!!!!!
I nearly had a panic attack just watching!
:sick:

According to this article he broke his ankle and had other injuries. I'm glad he wasn't hurt worse than he was. That sure looked like a nasty crash.
Edit: This ESPN article has some more info and (what appears to be) the same video with some sound.

Turns out they did have some super-stiff suspension, as evidenced by the coil spring falling off of the car!
