We created this simulation of the Audi A8 in cooperation with the Audi AG in 2007. With this simulation we laid the foundation stone for our collaboration with the Audi AG. The size and complexity of the simulation satisfied the management and since that our simulations are an inherent part of the creation process of new cars. The fact that we get the permission to show parts of the simulation but now shows how early we create this fully functional and usable virtual car for the management without the need to built it up in real. Many decisions for the Audi A8 were made because of this simulation. This satisfied and shows the advantages and need of virtual prototypes.
