Crash fatality risk and unibody versus body-on-frame structure in SUVs.
Highlights
•Many SUVs are now built with unibody, instead of body-on-frame,
construction
•The safety effects of unibody construction were unknown, both for SUV
occupants and for the occupants of other vehicles they crash with.
•Fatality risk was lower in occupants of vehicles struck by unibody
SUVs, compared to occupants of vehicles struck by body-on-frame SUVs.
•Unibody SUVs may also protect their own occupants better than body-on
-frame SUVs do.
Background
In crashes between cars and SUVs, car occupants are more likely to be killed
than if they crashed with another car. An increasing proportion of SUVs are
built with unibody, rather than truck-like body-on-frame construction.
Unibody SUVs are generally lighter, less stiff, and less likely to roll over
than body-on-frame SUVs, but whether unibody structure affects risk of
death in crashes is unknown.
Objective
To determine whether unibody SUVs differ from body-on-frame SUVs in the
danger they pose to occupants of other vehicles and in the self-protection
they offer to their own occupants.
Methods
Case–control study of crashes between one compact SUV and one other
passenger vehicle in the US during 1995–2008, in which the SUV was model
year 1996–2006. Cases were all decedents in fatal crashes, one control was
selected from each non-fatal crash.
Findings
Occupants of passenger vehicles that crashed with compact unibody SUVs were
at 18% lower risk of death compared to those that crashed with compact body-
on-frame SUVs (adjusted odds ratio 0.82 (95% confidence interval 0.73–0.94)
). Occupants of compact unibody SUVs were also at lower risk of death
compared to occupants of body-on-frame SUVs (0.86 (0.72–1.02)).
Conclusions
In two-vehicle collisions involving compact SUVs, unibody structure was
associated with lower risk of death both in occupants of other vehicles in
the crash, and in SUVs’ own occupants. | b********6

这个research不是找两个车一对一的干. 是fatality rate,跟谁比谁扛撞没关系.

comparison controlled for curb weight, if you want to check the full results.
One thing I've learned from these researches is that in a collision, the
threat to the people in the other car does not necessarily mean a good
protection to yourself.
You will need a way to diverge the impact. I saw a patent online today that
somebody in Ford redesigned the frame to make part of it absorb the energy
in case of collision, instead of using a one-piece solid frame.
