Audi Fast-Tracks Revised Power Unit in Barcelona After ADUO Clearance

Audi has wasted no time exploiting Formula 1's Additional Development and Upgrade Opportunities (ADUO), introducing a revised power unit at the Spanish Grand Prix after the FIA confirmed its concession status. Both cars received new internal combustion engines and turbochargers for the Barcelona race.

Why it matters:

The ADUO system helps struggling manufacturers close the gap to leaders like Red Bull Powertrains, the FIA's benchmark for combustion engine performance. Audi's rapid deployment proves development hardware was ready well before approval, signaling serious intent to climb the grid rather than accept a backmarker position.

The details:

• The FIA completed its first ADUO review after the Canadian Grand Prix and notified manufacturers in Monaco that Audi qualified for extra upgrades.
• Red Bull Powertrains raised concerns about the benchmarking process, but the FIA allowed the initial results to stand pending further review.
• FIA documents from Barcelona revealed new ICEs and turbochargers on both cars, featuring tweaks focused mainly on improving driveability.
• Sources indicate the revised units were developed in Ingolstadt and Hinwil for months, waiting only for final regulatory clearance before delivery to the track.

What's next:

This update marks only the opening phase of a broader program as Audi refines its package through the season. With hardware now collecting race data, further iterations are expected as the team pushes to extract more performance from its power unit.
