U.S.: SUVs progress in anti-rollover technology

WASHINGTON (AP) — Many new sport-utility vehicles, equipped with anti-rollover technology, are less of a risk for rollover crashes than their predecessors, the government says.

Rollover ratings issued by the National Highway Traffic Safety Administration for 2007 model year vehicles show SUVs making progress over past vehicles. The ratings give consumers information on the likelihood of a rollover, which kill more than 10,000 motorists in the United States every year, more than a third of motorists killed in the country annually, despite accounting for only 3 percent of all crashes.

Seventy-eight 2007 model year SUVs received a four-star rating in the rollover tests, according to an analysis by The Associated Press. More than half of the 2007 SUVs had four-star ratings, compared with 48 of the 2006 SUVs that earned four stars out of 103 SUVs rated. Only one SUV received four stars in 2001.

To guard against rollovers, automakers have increasingly installed electronic stability control into their vehicle lineup. The anti-rollover technology, which was first introduced by Mercedes-Benz in 1995, automatically applies brakes to individual wheels when the vehicle begins skidding off course, helping to steady the vehicle.

Eighty-six percent of 2007 SUVs have stability control as standard equipment, up from 43 percent in 2005, the government reported.

In NHTSA testing, no SUV has earned a top five-star rating. Under the system, a vehicle with five stars has a rollover risk of less than 10 percent. A four-star vehicle has a 10 percent to 20 percent risk and a three-star vehicle has a 20 percent to 30 percent risk.

Newly tested 2007 SUVs receiving the four-star rating include: Infiniti FX35, Mazda CX-7, Ford Edge and Explorer Sport Trac, Hyundai Santa Fe and Veracruz, Jeep Compass, Chevrolet Equinox, Honda CR-V, Volkswagen Touareg, Acura MDX and RDX, Suzuki XL7, and Saturn Outlook.
