This is a subject I'm interested in. I wanted to bring my Panda back from Europe but ran into issues. (Mad Scientist Matt was trying to help me find a way of adapting an OBDII system to the Panda's management because that's a requirement for emissions now. But that's another story...)
The differences between the NHTSA and the Euro-NCAP are (as summarized by This website ):
NHTSA:
- Full frontal impact into a deformable barrier at 35mph
- Side swipe by an SUV/Pickup at an oblique angle at 38.5mph
- Side swipe by a 25cm pole at a 75deg angle at 20mph
- Rollover test: car is tipped till it rolls. Angle is measured (not strength)
Euro NCAP
- Frontal= 40mph into 40% of frontal area
- Side swipe is done at 90deg into a "narrow" pole at 18mph
- Side swipe by a car at 31mph
- All tests done with a rear facing baby seat and a booster seat. Child safety is evaluated.
- Pedestrian strikes are evaluated for pedestrian safety rating.
- Whiplash rating for rear strikes evaluated.
So there ya go.
There is also the International Institute for Highway Safety (ran by insurance agencies, but not gov mandated)
- 40mph/40% frontal
- again with 25% frontal area
- Side impact with SUV @ 31mph
- Roof structure must hold 4x the vehicle weight before deforming 5-inches (crush)
- Drivers seat on sled test for whiplash. (simulated 20mph rear end)
I honestly think this is really a case of "Can't we all just get along?". I mean there are subtle differences in the NHTSA versus Euro NCAP, but reading the requirements I think this should be filed in the "As near as makes no difference" bin.
