Accord Euro Crash test vids i found

I was browsing youtube and came across these

Heres some footage to make us euro drivers see we have a safe car

crashtest1

crashtest2

crashtest3

=D watching them makes me see that i have a nice and sturdy car =P

Interesting!

I wonder how fast those crash test was at.

Why did the curtain airbags deploy in that first one...that was front on?

If you noticed the video title it says, "with SAB" meaning, with side airbags, be it curtain or actual side air bags.

Because the amount of Gs in a frontal crash into a wall (immovable object) is high enough to even set off the curtain airbag sensor. Crashing into a wall at 60km/h is worse than T-boning another car at 80km/h (guessing numbers). If you look at TV reports of fatal head on collisions on the freeway at 80km/h, the passengers die but the car has less damage than the Euro in this vid.

head on collisions with both cars travelling at 80km/h will be the same as running into a wall at 160km/h, maybe worse depending the the angle and position of impact.

I think the crash tests are mostly done at 60mph

Considering those videos above except the first one are NCAP crash tests, here is from their FAQ.

How does NHTSA perform the frontal crash rating and how are vehicles rated?

For frontal crash ratings, crash-rating dummies representing an average-sized adult are placed in driver and front passenger seats and secured with the vehicle's seat belts. Vehicles are crashed into a fixed barrier at 35 miles per hour (mph), which is equivalent to a head-on collision between two similar vehicles each moving at 35 mph.

No, it is not the same as running into a wall at 160km/h. Because the 2 cars will crush and absorb the impact force. When crashing into a wall, all of the impact force goes into that one car. Elastic and inelastic collisions :)

Well the equivalent is definitely more than 80km/h to a wall :P

What do you mean? 80km/h to the wall will kill people already from the internal injuries sustained from the deceleration forces.

You have to calculate it in order to determine which has more damage to the car. In both cases, momentum is conserved, but for inelastic collisions kinetic energy is lost as the car crumples. In a 2 car head on collision, the lost energy is absorbed by both cars crumpling. In a car-to-wall collision, the energy is absorbed by the car alone since the wall is immovable. So my guess is that a 80km/h wall test is equivalent to 2 cars head on at 80km/h (total 160km/h) assuming that both cars crumple the same and absorbed the same energy.

HI,

European NCAP Crash Tests are usually with 64km/h

These are the front (off set) crashs into a wall/barrier.

Only my 2 cents...

damn wow i made a mass debate with this one now =P ehehe lol
