A clearly visible alteration of the ID. R will be the aerodynamics. “In the thin air of Pikes Peak, which sits 4,302 metres above sea level, we gave the ID. R a very big rear wing to produce the maximum amount of downforce,” says Demaison. On the Nordschleife, Volkswagen Motorsport will bring a new aerodynamic configuration that will target the greatest efficiency possible, rather than maximum downforce. “This concerns not only a smaller rear-wing, but also the front splitter and floor of the vehicle,” explains Demaison. For this, different specifications are simulated on the computer to be then tested in the wind tunnel at the beginning of April, before being brought into action in test runs on the race track.
Volkswagen Motorsport in Hannover carry out these simulations, which are also put to use in order to optimise battery management and to adapt suspension components for the higher loads of the Nordschleife. “We are receiving a great deal of support from the technical development in Wolfsburg,” says Dr. Benjamin Ahrenholz, head of calculation/simulation at Volkswagen Motorsport. “As well as utilising the great know-how in production-car development, we also have the significant computer capacities of the Volkswagen Group at our disposal, since the simulations require a very high level of computer power.”
