VW-ID R into the Clouds – An Alliance of Aerodynamics and Composites

This presentation will start from the development of the Volkswagen I.D. R for Pikes Peak, explaining the important role played by aerodynamics and use of composites. High downforce and low weight are fundamental in this race. With 35% thinner air at the high altitudes of Pikes Peak, downforce is a corresponding 35% lower than sea level, compensated for, among other things, by the huge rear wing. Weight plays a key role in hill climbing. Bodywork and wings had to be stiff but extremely light. Technology and processes from F1 & LMP1 such as hollow structures, internal ribs and ultra-thin material were used to minimize weight and meet the challenges of these extreme conditions. After this achievement, the following target was the electric car record in Nürburgring. Race condition are completely different from Pikes Peak, and a deep review of all the aero was needed. Many bodywork components were modified. The Rear End in particular was designed from scratch, with completely new wings and endplates, stiffer pillars to reduce the natural frequencies and the introduction of the DRS system to reduce the drag in the long straights of the Green Hell.
