The Audi factory is "hectic" and a hive of activity despite the carmaker still being a few years away from entering Formula 1.
The world-famous automotive brand has already signed up for F1's new engine regulations, which will come into force for the 2026 season. Rather than forming their own operation, Sauber – currently racing under the Alfa Romeo banner – will become the Audi works team from that year onwards.
The Sauber base at Hinwil in Switzerland will remain a key facility, where the car itself will be designed and manufactured. Audi's factory in Neuburg, Germany, will be where the new power units will be created.
