USNCAP Testing Needs
Revision - The NHTSA
testing regimen remains virtually the same now, 23 years later,
as when it began. The only major addition has been a side-impact
test (adopted from the Euro-NCAP
side-impact test).
Recent testing by the International
NCAP Agencies has shown that the the full-width frontal crash
test does not show how effectively a vehicle's safety cage or
occupant restraint systems will protect the occupants of a vehicle
in real-world collisions. It is possible for a NHTSA
test to result in "good" head and chest injury measurements
(and therefore a good star rating) even though the structure
performs poorly or becomes unstable. In these cases the
risk to life in a slightly different crash configuration, or
slightly higher speed, could result in a much higher risk of
serious injury.
In the US,
mandatory airbag legislation has substantially equalized the
testing results of most full-width collisions. For example,
ALL of the vehicles tested by the NHTSA
in the past few years have earned a minimum of 3 stars in their
full-width collision. With no significant variation in
results, it's significantly harder for consumers differentiate
between vehicles.
In summary,
the US NCAP needs to adopt a more modern method of testing.
Australia has already abandoned the NHTSA
full-width test and has gone with the
Euro NCAP (EEVS) system. Adoption of the
IIHS or European EEVS testing system is clearly indicated
in the case of the US NCAP (NHTSA).
