“Our test programs are unique in their scope within the competition,” says Junige. A spectacular example: a lap of the Nürburgring Nordschleife – at the limit. The input for this comes from the virtual prototype. All simulated impulses are fed into the combined test bench in real time. “The vehicle must deliver full power under all conditions as soon as the driver demands it,” Junige emphasizes. This so-called maximum power release is pure stress, especially for the thermal management of the high-performance vehicle: To optimally condition the battery under all conditions, the heating and cooling systems are designed to be more powerful than in any previous electric Porsche. At every point during the Nürburgring lap, the values measured on the combined test bench are compared with those previously calculated for the digital twin. This has confirmed that the simulation is now so accurate that there are hardly any deviations left that need to be corrected based on the physical test results.
