Audi saves major ADUO upgrade for 2027Audi will not exploit every available ADUO development opportunity this season, after making a stronger-than-expected start to its Formula 1 project. Gabriel Bortoleto, Hungarian GP 2026© AudiRace director Allan McNish says the next major power unit upgrade will wait until 2027, with Audi instead preserving resources under the budget regulations. We used ADUO to implement small improvements in Barcelona right away, said the former Toyota driver. Therefore, we won't see any major changes to the power unit until then. Audi is quite an interesting destination, because they are making good progress, he said on the Red Flags podcast.
