Audi's full transition from a Sauber customer to a works team requires significant facility upgrades. The Sauber Engineering hub in Hinwil must expand to accommodate a new Formula 1 simulator, a critical tool for developing its 2026 powertrain. This physical integration mirrors the operational shift from Ferrari customer to full manufacturer.

The move underscores Audi's massive investment ahead of its 2026 debut. Combining Hinwil's chassis expertise with Neuberg's powertrain division creates a unified German-Italian operation. A state-of-the-art simulator is non-negotiable for competitive development, allowing real-time correlation between engine and chassis data before the first on-track test.

All eyes are now on how quickly Audi can complete this expansion. The simulator's readiness will directly impact the team's 2026 pre-season testing performance. For Sauber's existing staff, the integration marks a pivotal cultural and technical shift, moving from a customer relationship to a fully integrated manufacturer team.
