A top score in the new IIHS rollover (roof-crush) test assures the award. While the SRX had already earned top 'good' ratings for frontal, side, and rear crash protection, the organization saves its Top Safety Pick designation for top scores in all those categories, plus the rollover test and the availability of electronic stability control.
In the roof test, the IIHS measures protection the vehicle might provide in the event of a rollover, by seeing how much constant force the roof will take in a particular location (and with a particular contact plate) before it deforms five inches. That force is then divided by the weight of the vehicle.
The SRX roof withstood 4.14 times its weight—although the IIHS cautions that GM strengthened the roof partway through the model year, and the results only apply to SRX models built after May 2010. To get a 'good' score, a vehicle must be able to withstand four times its body weight in the test. The current federal standard is just 1.5, though it's due to be doubled by 2016.
For 2010, the Cadillac SRX was completely redesigned—as well as realigned as a completely different kind of model than before. While the previous SRX had been based on a rear-wheel-drive sedan platform, this new version is related to the Chevrolet Equinox.
In our full review of the 2010 Cadillac SRX, we point to its rich interior appointments, strong engine performance, and excellent brakes as likes, though engine noise was a disappointment. The SRX competes in one of the hottest segment of the market, with some of the many alternatives including the Lexus RX 350, Volvo XC60, Audi Q5, and Mercedes-Benz GLK.
