Watch the XC60 conquer IIHS's new Small Overlap Frontal Crash Test. In the test, 25 percent of a car's front end on the driver side strikes a 5-foot-tall rigid barrier at 40 mph. The test is designed to replicate what happens when the front corner of a car collides with another vehicle or an object like a tree or utility pole. Outside of some automakers' proving grounds, such a test isn't currently conducted anywhere else in the United States or Europe.
