The C 111 had now no longer most effective been designed with a futuristic shape. It is likewise the world's first automobile that were absolutely designed on a computer. For this purpose, engineers used the ESEM method (elastostatic detail method), a finite detail method (FEM) variation evolved at Mercedes-Benz. The virtual era even made it viable to calculate dynamic loads. Mercedes-Benz estimates that the improvement length turned into reduce through round 4 months through the usage of this method. The in-residence documentary movie production "Das Auto, das aus dem Computer kam" (the auto from the computer) delivered the innovation.
