The Insurance Institute for Highway Safety says that the Volvo S60 earned top marks in all of its tests.

Volvo, long associated with safety, now has another reason to celebrate: The Insurance Institute for Highway Safety has named its newest model, the S60 sedan, to its coveted Top Safety Pick list.

The S60 performed well in all of IIHS' tests, including front, side and rear impacts, as well as a newly-instituted roof strength measurement. The ratings apply only to the redesigned 2011 and 2012 S60. Unlike the previous S60, a designed that dated back to the late 1990s, the new car earned top marks all around.

In the roof strength test, IIHS found that the S60 can withstand an application of 4.95 times its curb weight, a figure that puts it second only to the Mercedes-Benz C-Class in the midsize luxury sedan class. IIHS has not tested all of the S60's rivals, but the Volvo does rank ahead of the Lincoln MKZ, Audi A4 and Lexus HS 250h.

The S60 joins Volvo's C30, S80, XC60 and XC90 models on IIHS' Top Safety Pick list.
