2010 Cadillac SRX IIHS testing – Click above for high-res image gallery

When it comes to the Insurance Institute for Highway Safety's crash rating system, earning a score of "Good" is the best any automaker can hope for. And if a vehicle receives a score of "Good" for front, side, rear and and rollover crash protection and the vehicle has standard electronic stability control that car, truck or SUV becomes an IIHS Top Safety Pick. The 2010 Cadillac SRX became the 15th midsize SUV to be awarded with the desirable designation after the hot-selling crossover passed the rollover crash protection test with flying colors. The SRX had already received a "Good" score for its performance in the other crash tests.

The current government standard for roof safety is that it needs to be able to support 1.5 times the overall vehicle weight. The roof of the SRX proved to be able to hold 4.14 times its weight, nearly tripling the standards required by the feds. The IIHS tests roof strength by pushing a metal plate against one corner of the roof at a constant rate of speed. The maximum force sustained by the roof before the roof collapses by five inches is compared to the vehicle weight to determine the strength-to-weight ratio. Hit the jump to read over the IIHS presser.

2010 Cadillac SRX earns TOP SAFETY PICK award

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. Consumers now have 15 midsize SUVs to choose from that earn top crash ratings across the board.
