As is common with expensive, smaller-volume luxury vehicles, neither the NHTSA (National Highway Traffic Safety Administration) nor the IIHS (Insurance Institute for Highway Safety) have crash-tested the 2013 BMW X6.
The IIHS has, however, crash-tested the 2012 model of the X5, with which the X6 shares much of its core structure. The 2012 BMW X5 earned top marks of "good" in all tests. The X6's structure is somewhat different, however, so a direct correlation can't necessarily be inferred.
Standard safety equipment on the X6 includes front, side, and side-curtain airbags; stability and traction control (with M Dynamic Mode enhancements on the X6 M); hill-descent control; and anti-lock brakes.
Optional safety upgrades include a backup camera, adaptive cruise control, and lane-departure warning system.
