I've got an old VHS, no idea where it came from, featuring "crash tests" of trains. Old school steam engines that were pending the crusher were bought cheap and crashed into each other. Call it a demonstration, crash test, whatever, but spectators were most definitely there.
Now there is an idea for the auto manufacturers to make a little extra cash - sell tickets to the destruction tests. Heck, were I in town, I'd buy one! A great place to take a date.
You see, this is why the IIHS and NHTSA crash all new cars through a wall of fire. How else would you know that you and your family be safe, if you were to crash into a wall of fire?
looks like they are trying to sell to law enforcement.
RELATED I went through the NHTSA training for passenger safety in the late 90's to participate in child safety seat installations and related community service. During the training class we were shown films from Germany where they used live prisoners for crash testing, during lunch no less. They were taken around the 1950's. No one is killed but they are a hoot to watch. Has anyone else seen these? and if so are they available online?
On the bright side, a bit of roof crush in a rollover means you roll less. If you don't have any energy dissipation in a roll situation, you just keep rolling.
There are many places in the CO high country which almost beg to have vehicles rolled down them, sideways. Station a lifting 'copter nearby, and roll away.
You'd get the forces of more than one roll, the vehicle's shape affecting it, and the randomness of rocks/boulders.
Plus, it'd be entertaining to watch. Not even a 30 minute drive from Denver.
My personal testing gives the Chevy Silverado pickup 5 stars, thankfully none of us were injured in our Christmas Day roll-over last year (on the way to the Thunderhill LeMons race)
@engineerd: The car (Pujo! the Cheese Eating Surrender Monkeys' Peugeot 505) broke free of his tie down straps and bounced around in the trailer like a drumstick in a bag of Shake-n-Bake.
After tearing the roof off the trailer, Pujo! was dragged by his ass up out of the culvert and drove home (minus a few windows).
@SeanKHotay: So you're saying the crystalline structures of metals might deflect differently under rapid shock as opposed to steady force? That's just ridiculous.
@sdvictor: Yes, it somewhat does. FIA uses a similar multidirectional method (albeit via FEA) for their roll cage approval process.
Problem is, the A-pillar disappears on a certain vehicle like crushing a tin can under your foot during a proposed dynamic 'trip' rollover test...though it passes this static test.
Physics is theory put to application, reality is reality.
I understand the reason for using a multplier of the car's own weight to perform the test, but it would also be nice to know an absolute figure. It's not surprising that the Smart performed well since it's so light. I would like to know how the Smart and the Aveo compare (for example) when an equal force is applied to both roof structures, and not some multiple of the car's own weight.

For the love of God, can't they perform tests with even some semblance of reality?

The US automakers have proven they know sh*t about physics and auto safety with their constant fight against rollover roof standards.

I am thinking six times its weight...sure, sure its not at an angle, but them volvo engineers were ahead of the curve...
