The Cadillac SRX, a midsize luxury SUV, earns the Institute's top safety designation after getting a good rating for rollover protection. The SRX had previously earned good ratings for front, side, and rear crash protection.
Top Safety Pick recognizes the vehicles that earn the highest ratings in all 4 Institute safety evaluations, and that have electronic stability control, which is standard on the SRX.
Based on research of real-world crashes, the Institute evaluates rollover protection using a roof strength test. In this test a metal plate is pushed against one corner of a vehicle's roof at a constant speed. The maximum force sustained by the roof before 5 inches of crush is compared to the vehicle's weight to find the strength-to-weight ratio. This is a good assessment of vehicle structural protection in rollover crashes. Good rated vehicles have roofs that can withstand a force equal to at least 4 times the vehicle's weight.
The roof of the '10 SRX withstood a force equal to 4.14 times weight. For comparison, the current federal standard is 1.5 times weight.
General Motors strengthened the roof structure of the SRX during the 2010 model year. The Top Safety Pick award applies to models built after May 2010.
