Mercedes-Benz ESF Safety Concept Vehicle
The ESF 2009, based on the Mercedes S 400 HYBRID, is the first Experimental Safety Vehicle to be built by Mercedes-Benz since 1974.
Among the highlights of the ESV was the Mercedes-Benz unveiling of the ESF 2009 – an experimental safety vehicle with trailblazing innovations including: inflatable metallic sections to afford more stability to structural components within fractions of a second, and a “Braking Bag” housed within the vehicle floor and more.
