The Audi e-tron GT is the first four rings model for which production was planned entirely without physical prototypes. Multiple technical innovations made this possible, including three-dimensional building scans, machine learning processes and the use of virtual reality. All assembly processes, such as procedures and employee actions were tested and optimized in virtual spaces that model their real-world counterparts down to the finest detail. Virtual planning is now used across site boundaries, enabling digital, connected working without business trips or foreign assignments – and not just during the coronavirus pandemic. 3D scans and the planning in virtual spaces make processes more efficient and sustainable.
