Tougher government crash tests for the 2011 model year are making it harder
for car makers to win coveted "5-star" safety ratings for their vehicles,
which they widely tout in ads.
The U.S. Transportation Department on Tuesday formally launched a more
rigorous system for grading car safety. The new system for the first time
gives vehicles one overall safety rating, as well as various subratings,
with one star for the worst and five stars for the best.
The system, which applies to cars and light trucks starting in the current
2011 model year, means fewer top safety ratings. In effect, too many
vehicles were getting top scores on the government's previous crash tests,
so regulators made the tests harder.
For the first time, the tests use crash-test dummies to gauge the impact of
a crash on women, not just men. The tests also simulate a crash into a pole
on the driver's side, and the ratings will note for the first time whether
cars contain certain accident-prevention technologies, such as electronic
stability control.
Some industry officials are concerned that consumers could be confused by
the change, since ratings for vehicles from the 1990 through 2010 model
years won't be comparable with those issued under the new, more-demanding
system.
The U.S. plans to test about 55 vehicles from the 2011 model year under the
new system. Of the 33 tested so far, only two achieved an overall score of
five stars: BMW AG's BMW 5 Series and Hyundai Motor Co.'s Sonata.
That compares with 99 models from the 2010 model year that received five
stars in both the front and side crash tests.
Some vehicles that are largely the same for 2011 as they were in 2010 will
get lower scores. Ford Motor Co.'s Taurus, which won a five-star front crash
rating for 2010, earned only four stars for 2011 in both frontal crashes
and overall safety. The 2011 Toyota Motor Corp. Camry received three stars
for its front crash rating, and three stars overall. For 2010, Camry earned
a five-star front-crash rating and five-star side-crash rating.
Toyota—which recalled millions of vehicles this year for safety concerns—
said in a statement it anticipated the ratings could go down under the new
system. "Toyota engineers are investigating measures to further enhance
safety performance so Camry again obtains outstanding assessment results
under the new rating system," the company said. | a*******a

"the new tests will include dummies with a wider variety of body types and
more sensors to measure damage in a crash test."
"The only concern he mentioned was in the transition year. Because the new
system uses the side-impact pole test, a wider variety of dummy body types
and impact sensors, 2010 and 2011 safety ratings cannot be compared.
"It's like comparing apples and oranges," Cyrill said."
