WASHINGTON, D.C. – The number of SUVs with a four-star
rollover rating has increased substantially since the U.S.
Department of Transportation’s National Highway Traffic
Safety Administration (NHTSA) began rating them in 2001.
That year, just one SUV earned four stars, whereas in 2005,
24 earned a four-star rating as part of the newly released
rollover test results for 2005 model-year vehicles.
Assessing static stability factor values – the predominant
factor in NHTSA’s rollover ratings – the agency found a
significant improvement in SUV ratings; passenger car and
pickup truck scores have remained relatively constant.
For 2005 model-year tested vehicles, the highest-rated SUV
was the Ford Freestyle 4x4, earning four stars and a 13%
chance of rollover if involved in a single-vehicle crash.
The Freestyle matches the 2005 Chrysler Pacifica, a
carryover vehicle from 2004, which also earned four stars
and a 13% chance of rollover during the 2004 model-year
For pickups, the highest-rated vehicles were the Chevrolet
Colorado 4x4 and its twin the GMC Canyon, the Dodge Dakota
4x4, and the Dodge Ram 1500 4x2 – each earning four stars
and a 17% chance of rollover if involved in a single-
vehicle crash. For vans, the highest-rated vehicle was the
Chrysler PT Cruiser, earning four stars and a 13% chance of
rollover if involved in a single-vehicle crash. For
passenger cars, the highest-rated vehicle was the Ford
Mustang, earning five stars and an 8% chance of rollover if
involved in a single-vehicle crash.
"It is encouraging to see the positive impact our rollover-
rating program has had on making vehicles more stable,
particularly on SUVs," said NHTSA Administrator Jeffrey
Runge, M.D. "Today we have 24 2005 model-year SUVs with a
four star rollover rating, whereas two years ago, we had
