The Insurance Institute for Highway Safety hasn't yet tested the Escalade, but this SUV has received quite good ratings in the new, more stringent testing NCAP testing system from the federal government. In it, the National Highway Traffic Safety Administration (NHTSA) gave it a four stars overall, including five stars for frontal impact and five stars for side impact. It was apparently graded down only for its three-star rollover calculation. But it also received top five-star rating in the new side pole test, which gauges the chances of injury in a sideways collision with a tree or pole.
The 2011 Cadillac Escalade has most of the safety features you might look for in a large SUV, including front side airbags, head-curtain side airbags covering all three rows, and a StabiliTrak stability control system that includes rollover mitigation to help avoid situations that might lead to a rollover.
