regardless of crash safety ratings

provide a false degree of confidence'

BUFFALO, N.Y. – Most consumers who are shopping for a new car depend on
good crash safety ratings as an indicator of how well the car will perform
in a crash. But a new University at Buffalo study of crashes involving cars
and sport utility vehicles (SUVs) has found those crash ratings are a lot
less relevant than vehicle type.
The study is being presented May 16 at the annual meeting of the Society of
Academic Emergency Medicine in Atlanta.
In head-on collisions between passenger cars and SUVs, the UB researchers
found that drivers in passenger cars were nearly 10 times more likely to die
if the SUV involved had a better crash rating. Drivers of passenger cars
were more than four times more likely to die even if the passenger car had a
better crash rating than the SUV.
“When two vehicles are involved in a crash, the overwhelming majority of
fatalities occur in the smaller and lighter of the two vehicles,” says
Dietrich Jehle, MD, UB professor of emergency medicine at Erie County
Medical Center and first author.
“But even when the two vehicles are of similar weights, outcomes are still
better in the SUVs,” he says, “because in frontal crashes, SUVs tend to
ride over shorter passenger vehicles, due to bumper mismatch, crushing the
occupant of the passenger car.”
When crash ratings were not considered, the odds of death for drivers in
passenger cars were more than seven times higher than SUV drivers in all
head-on crashes. In crashes involving two passenger cars, a lower car safety
rating was associated with a 1.28 times higher risk of death for the driver
and a driver was 1.22 times more likely to die in a head-on crash for each
point lower in the crash rating.
The UB researchers conducted the retrospective study on severe head-on motor
vehicle crashes in the Fatality Analysis Reporting System (FARS) database
between 1995 and 2010. The database includes all motor vehicle crashes that
resulted in a death within 30 days and includes 83,521 vehicles involved in
head-on crashes.
“Along with price and fuel efficiency, car safety ratings are one of the
things that consumers rely on when shopping for an automobile,” says Jehle.
These ratings, from one to five stars, are based on data from frontal, side
barrier and side pole crashes that compare vehicles of similar type, size
and weight. The one to five star safety rating system was created in 1978 by
the National Highway Traffic Safety Administration.
Jehle notes that after manufacturers addressed the roll-over problem with
SUVs that plagued these vehicles in the 1980s and 1990s, rollover crashes
are now much less common in SUVs.
“Currently, the larger SUVs are some of the safest cars on the roadways
with fewer rollovers and outstanding outcomes in frontal crashes with
passenger vehicles,” he says.
Jehle says that prior studies on frontal crashes have found that compared to
passenger cars with a 5-star crash rating, cars with a rating from one to
four stars have a 7-36% increase in driver death rates.
“Passenger vehicles with excellent safety ratings may provide a false
degree of confidence to the buyer regarding the relative safety of these
vehicles as demonstrated by our findings,” says Jehle. “Consumers should
take into consideration the increased safety of SUVs in head-on crashes with
passenger vehicles when purchasing a car.”

真正需要关心的是,Sedan A和SUV B,各自撞上SUV C后,A和B中的乘客那个更容易死.当
然最需要关心的还是,把所有可能的事故都算进去(包括翻车,撞墙,撞车)以后,哪个车死
亡率更高. | A***n

而重的，出事时叫对方吃亏。

者占上风。 | b********6
发帖数: 35437 | 6 这篇文章是想告诉消费者，有些sedan虽然是top safety picker，但是只是在同级别的
车里评比的结果。碰到更大的车也是吃亏。
很多人觉得只要是top safety pick就很安全了
