The rules have been changed as a result of cancellations
The FIA has accelerated an important lifeline for struggling F1 power unit manufacturers to later this month.
Changes in the 2026 F1 season schedule have impacted the timeline for Additional Development and Upgrade Opportunities (ADUO) periods, originally scheduled after races six, 12, and 18.
The first ADUO period will now take place after the fifth race, the Canadian Grand Prix, due to the cancellation of the Saudi Arabian and Bahrain Grands Prix.
ADUO aims to assist power unit manufacturers facing challenges with developing reliable, fast engines under the 2026 regulation changes.
These adjustments may provide an opportunity for other power unit manufacturers like Ferrari, Red Bull, Audi, and Honda to narrow the gap with dominant Mercedes in the upcoming races.
