The FIA has announced that its ADUO regulations, aimed at lagging power unit manufacturers, will commence after the F1 Canadian GP weekend.
The FIA will implement its ADUO regulations aimed at addressing lagging power unit manufacturers starting after the Formula 1 Canadian Grand Prix weekend. The 2026 F1 season marks the introduction of a hybrid 50-50 power unit, creating a significant performance gap between engine manufacturers. The FIA has recognized this gap and initiated the Additional Development and Upgrade Opportunities (ADUO) scheme to address it. The ADUO programme will now be activated following the race weekend at the Circuit Gilles Villeneuve, the sixth round of the adjusted F1 calendar. Eligibility for ADUO will allow manufacturers to develop their engines beyond cost-cap and testing restrictions, with the first assessment period covering the first five races of the season. Five engine manufacturers, including Mercedes and troubled Honda, are currently on the grid, with potential eligibility for the ADUO scheme based on performance criteria. The ADUO eligibility list will be revised twice more this season, offering manufacturers like Honda the chance to improve their engines and performance.
