Safety

The X3 earned a 2009 Top Safety Pick designation from the Insurance Institute for Highway Safety, the agency's highest award. That means it earned top scores in IIHS' frontal-offset, side-impact and rear crash tests. All X3s have standard electronic stability control and a full complement of airbags.

As of publication, the Q5, GLK350 and XC60 hadn't been tested by IIHS.
