The Insurance institute for Highway Safety reports, that some sport utility vehicles do not provide enough protection in side crash tests. The IIHS gave good scores to the 2008 versions of the Ford Explorer, Toyota FourRunner, Jeep Grand Cherokee, Nissan Pathfinder and Nissan Xterra. The Chevy Trailblazer, GMC Envoy, Isuzu Ascender and Saab 9-7X, all received an "Acceptable" score for frontal offset crash testing, seperating themselves from the group. The Institute's senior vice president, David Zuby, stated "People often think they’re safer in one of these vehicles, but many cars hold up better than some of these midsize SUVs in this test".
