Red Bull and FIA Collaborate to Refine ADUO Engine Upgrade System

Red Bull Racing is working closely with the FIA to tweak the Additional Development and Upgrades Opportunities (ADUO) system for 2027. Despite Mercedes' overall dominance in the current regulations, the ADUO system identifies Red Bull as the technical benchmark, leaving the team ineligible for the upgrade tokens granted to lagging manufacturers.

Why it matters:

The ADUO system was introduced in 2026 to maintain competitive parity by granting tokens to manufacturers trailing in performance. However, because the system currently only measures the Internal Combustion Engine (ICE) rather than the entire hybrid power unit, it creates a distorted view of the grid's hierarchy, potentially penalizing teams with a strong ICE but inferior overall integration.

The Details:

• Token Distribution: Under the latest FIA assessment, Mercedes received one token (2-4% power deficit), while Ferrari, Audi, and Honda received two (over 4% deficit). Red Bull received zero.
• Methodological Flaws: FIA single-seater director Nikolas Tombazis has acknowledged "weaknesses" in the system. Red Bull argues that the current metrics fail to capture the full performance picture of modern hybrids.
• Development Focus: Team boss Laurent Mekies insists that Red Bull is focusing on "360-degree" development. This includes optimizing operating windows and chassis integration for the RB22 to compensate for the lack of hardware tokens.

The Big Picture:

Red Bull’s 2026 campaign has been a testament to their in-season development capabilities. After starting the year on the back foot with a significant deficit, the team has steadily closed the gap. This resilience culminated in Max Verstappen securing his first victory of 2026 in Malaysia, proving that software and chassis optimization can still offset hardware limitations in the new era.

What's next:

The FIA and Red Bull are now in active discussions to evolve the ADUO methodology for 2027. The goal is to create a more holistic assessment of power unit performance that reflects real-world track capability rather than isolated engine data.
