You've probably never heard of Béla Barényi, but you've almost certainly been impacted by him in some way, shape or form. The Austro-Hungarian engineer had a huge effect on the automotive industry, most notably during his 33-year tenure as the head of pre-development for Mercedes-Benz, where he helped revolutionize and popularize the idea of passive safety.

Crumple zones, collapsible steering columns and the idea of a passenger cell can all be credited to Barényi while he was at Mercedes, as this fascinating historical video from the German manufacturer points out. Besides detailing Barényi's successes, it includes some great video of the testing processes used for old Silver Arrows - you'll be amazed by how many times an old, boat-like Mercedes sails through the air or crashes into something in this three-minute video.

Take a look below, and let us know what you think.
