发帖数: 754 | 1 America’s Most Dangerous Luxury Cars
August 15, 2012 by Mike Sauter
More than 10,000 people are killed each year in front-end crashes in the
United States. While most cars offer protection in front-end accidents,
overlap crashes, where the car is not hit head-on, are a different matter
entirely. Until now overlap crashes, which account for nearly one in four of
the front-end crashes involving serious or fatal injury to front seat
occupants, have not been tested by the government or other independent
testing facilities.
On Tuesday, the Insurance Institute for Highway Safety (IIHS) released test
results of this new type of crash safety test for 11 of America’s popular
midsize luxury vehicles. Only three models passed. Eight models failed. Like
studies before it, it will change the way automakers approach building
their vehicles.
Since 1995, when the IIHS began testing American vehicles, it has expanded
its safety ratings to four major categories: front, side, rollover and rear.
As each new test has come out, IIHS spokesman Russ Rader told 24/7 Wall St.
, most cars failed at first, but eventually vehicles were built to pass the
test. To date, the vast majority of popular vehicles passed each of the
other four test categories with full marks, including perfect scores for
most of the cars on this list.
Interest in the overlap test was motivated by concern that front-end crash
safety measures remained inadequate. “Even though we’ve had all this
improvement in frontal crash protection through the testing the institute
does and through the testing the federal government does,” Rader explained,
“we still have 10,000 people getting killed in frontal crashes, and we
wondered ‘why is that?’”
The small frontal overlap test is, according to Rader, likely going to
change the way automakers approach building their cars for safety. “We
expect that other automakers are going to add this to their development
process because this is a competitive market, and all the manufacturers
strive to get the highest safety ratings.”
The new test, called the “small overlap frontal crash test,” involves only
one quarter of the front of the car hitting a rigid barrier at 40 MPH. In
traditional front-end tests, half of the vehicle hits a barrier. The new
test measures what happens to a front-seat driver or passenger when this
kind of crash happens. The scores are the same as for the agency’s other
tests: good, acceptable, marginal and poor.
The IIHS tests pointed to several common problems with this type of impact,
including the failure of side airbags to deploy, car parts trapping the
driver’s feet or causing the door to shear off. Another common problem
involved the driver’s head sliding off the airbag — or even missing it
entirely — and hitting the corner of the car.
The IIHS put mid-sized luxury models through the new test first because,
Rader explained, those are the automobiles that “tend to get the most
advanced safety and engineering systems first.” For example, according to
Rader, the institute’s research showed that at least one luxury model, the
Volvo S60, was built with this unique type of accident in mind. In the test,
the S60 was one of only two vehicles, along with the Acura TL, to receive a
“good” score.
The eight cars on this list are generally well-built, but are not designed
to deflect small overlap frontal crashes. In addition to IIHS’s rating, 24/
7 Wall St. also looked at several other measures of overall safety and
quality for these vehicles, such as Consumer Reports ratings and J.D. Power
’s overall Initial Quality report. While some have received poor quality
scores, the majority perform well. These cars are, for the most part, well-
built but are not designed to deflect small overlap frontal crashes.
Unless these automakers make improvements to these models to address this
safety flaw, the already flagging sales figures of these cars could decline
further. Already, sales of six of the eight models on the list have fallen
in the past three years, according to sales data provided by Edmunds. Sales
of the BMW 3 series has declined by 32.9% between 2007 and 2011. In that
same time frame, U.S. unit sales of the Lexus ES 350 have declined by more
than 50%.
Two of the models listed in this study, the TSX and the TSX Wagon, were
tested separately, bringing the total number of vehicles tested by IIHS to
11, and the total number that received a poor rating to nine. However, as
they received the same overall score, a “marginal,” we refer to both
vehicles in the same study.
1. TSX/ TSX Wagon
> Make: Acura
> Small overlap frontal crash test rating: marginal
> 2011 sales: 19,594
> Price: $30,010
> J.D. Power Initial Quality: 4 out of 5
The Acura TSX Sedan and Wagon were tested separately, and each scored just
“marginal” in IIHS’s new frontal crash test, despite receiving perfect
scores for IIHS front, side, rear and rollover crashes. The institute
conducted two tests on the car because the side cameras were destroyed in
the first. In one of the two tests, neither the driver side curtain nor the
side torso airbags deployed. The report concludes that “injuries to the
left lower leg, ankle, and heel would be likely in a crash of this severity.
” Sales of the Acura fell by just 6.4% between 2007 and 2011.
2. 3 Series
> Make: BMW
> Small overlap frontal crash test rating: marginal
> 2011 sales: 94,371
> Price: $34,900
> J.D. Power Initial Quality: 4 out of 5
In the BMW 3-series’ crash test, the side torso airbag did not deploy and
the side curtain airbags did not have “sufficient forward coverage to
protect the head from contact with side structure and outside objects.”
Meanwhile, the footrest came toward the passenger substantially in the crash
, which IIHS said could cause injuries to the ankle, heel and right lower
leg. For the other four safety tests (front moderate overlap, side, rollover
, rear), the vehicle received scores of “good.” Sales of the BMW 3 series
in 2011 were 6.5% lower than in 2010 and nearly a third lower from what they
were in 2007.
3. MKZ
> Make: Lincoln
> Small overlap frontal crash test rating: marginal
> 2011 sales: 27,529
> Price: $34,755 (Sedan)
> J.D. Power Initial Quality: 5 out of 5
Like most of the cars on this list, the Lincoln MKZ scored “good” on IIHS
’s Top Safety Pick tests, but scored marginal on the small overlap frontal
crash test. In that test, the dummy’s head and chest “completely missed”
the front airbags, while the side curtain airbags did not provide sufficient
forward coverage for the head. Nevertheless, the car received highs marks
from Consumer Reports for its crash-test results, along with its quietness,
ride and handling. 2011 sales of the MKZ and MKZ Hybrid were down nearly 20%
from 2007, but sales in 2011 were 22.2% better than in 2010.
4. CC
> Make: Volkswagen
> Small overlap frontal crash test rating: marginal
> 2011 sales: 29,502
> Price: $28,515 (Sedan)
> J.D. Power Initial Quality: 3 out of 5
The Volkswagen CC sedan debuted in 2008. Despite mixed reviews, including a
J.D. Power initial quality score of three out of five, the vehicle has grown
its user base. Units sold have increased every year, and went up by 24%
between 2009 and 2011. According to IIHS’s small overlap frontal crash test
rating, the car’s door was “sheared off its hinges.” The report added,
“The CC is the first vehicle the institute has ever evaluated to completely
lose its door.” IIHS explained that any vehicle that loses its door
automatically fails a test as the driver could be ejected from the vehicle.
5. C Class
> Make: Mercedes-Benz
> Small overlap frontal crash test rating: poor
> 2011 sales: 43,349
> Price: $37,220
> J.D. Power Initial Quality: 2 out of 5
The Mercedes C-Class was given a score of “poor” in its small overlap
frontal crash test, despite receiving good marks on the other IIHS tests.
Neither the side curtain nor side torso airbags deployed in the test, and
the dummy’s foot was stuck beneath the brake pedal. The pedal had to be cut
off to free the foot. IIHS also noted the seat belt allowed for too much
forward movement, with the head at risk of hitting the A-pillar, which is
the vertical support near the driver’s seat. In 2011, sales were 8.8%
higher than 2007 sales and 17.9% higher than in 2010.
6. IS 250/350
> Make: Lexus
> Small overlap frontal crash test rating: poor
> 2011 sales: 29,669
> Price: $40,220
> J.D. Power Initial Quality: 4 out of 5
The Lexus IS 250/350 was also given a score of “poor” in its small frontal
overlap crash test, with the structure/safety cage, lower leg/foot and the
restraint/dummy kinematics receiving poor scores. The side torso airbag did
not inflate and the head actually moved outside the open side window at one
point during the test. Meanwhile, the brake pedals had to be cut off in
order to free the right foot. Nevertheless, Lexus was named by J.D. Power
and Associates as the most problem-free nameplate in America, with a score
of 73 problems per 100 vehicles. The 29,669 combined Lexus IS 250, 350 and
500Fs sold in 2011 represented a 46% decline from 2007 and a 13.1% decline
since 2010.
7. A4
> Make: Audi
> Small overlap frontal crash test rating: poor
> 2011 sales: 35,234
> Price: $32,500
> J.D. Power Initial Quality: 2 out of 5
During the new test, the footrest and instrument panel moved toward the
driver, making injuries to the left hip likely in the event of an accident.
The dummy’s head did hit the front airbag but slid off to the left side,
while the side torso airbag did not deploy. Furthermore, the driver door
opened during the crash, placing the driver at risk of being ejected from
the vehicle. Nevertheless, Consumer Reports points out the crash test
results were one of the highs scores for the A4, along with agility,
acceleration, transmission, fuel economy, fit and finish. In 2011, sales of
the A4 were 22.4% lower than in 2007, although 2011 sales improved 1.6% from
the previous year.
8. ES 350
> Make: Lexus
> Small overlap frontal crash test rating: poor
> 2011 sales: 40,873
> Price: $36,725
> J.D. Power Initial Quality: 5 out of 5
When the IIHS put the Lexus ES 350 through its new test, the dummy’s head
barely made contact with the front airbag, with the head sliding off the
left side. Meanwhile, the steering column moved significantly to the right
and up, diminishing the protection to the chest in a high-impact collision.
Neither the side curtain airbag nor the side torso airbag deployed in the
crash test. IIHS notes that “injuries to the left knee and left lower leg,
ankle, and heel would be likely in a crash of this severity.” Despite this,
the car received “good” scores for all the other “Top Safety Pick”
crash tests, with an exception of a “marginal” rating in the rear crash
protection test. In 2011, the ES 350 sales were a whopping 50.7% lower than
2007 sales, including a 16% drop from 2010.
