The Insurance Institute for Highway Safety has recently unveiled nine more cars for its prestigious “Top Safety Pick” award. The IIHS tests every new model in several tests to earn the award, and the car must perform well in each test in order to qualify.

This year’s awards added a new test for roof strength, which is important in rollover situations, according to the Chicago Tribune. In addition, the cars must pass 40-mph frontal crash tests, side crash tests, and rear crash/whiplash tests, as well as be equipped with an electronic stability control system.

Ford picked up awards for its Ford Fusion and Flex, as well as its luxury Lincoln MKZ and MKT. The Audi A4 and Hyundai Tucson were also recent winners.

The tests take some time, so the winners are released in waves. Previous 2010 model award-winners include the Honda Civic and Element, Mercedes E and C Class and Toyota Corolla and Avalon.

The IIHS has done the tests since 2006 and keeps archives of all the winners by model year on their website. Drivers searching for a used car can use this as a resource to ensure that their next purchase is of the highest quality.
