Mercedes did not do well on the small overlap crash test when it was first introduced. IIHS 2012 Mercedes C class They've improved since, but it's evidence they engineered to the tests. This is as opposed to Volvo and Subaru who did well with their existing cars when the small overlap test was introduced, evidence to me that they were engineering to real world safety, not just crash tests. A high standard, I know, but when it comes to choices in new vehicle purchases, this is at the top of my list. Don't get me wrong - I'll take a Mercedes, particularly a newer (post 2012) one over any other car (other than Volvo, Subaru, and Tesla).
