Binotto Proposes 'Unique System' to Align FIA ADUO with Chassis Convergence Model

Audi chief Mattia Binotto is urging the FIA to replace the raw power-based foundation of its new Additional Development and Upgrade Opportunities (ADUO) system with a unified convergence model. He argues the chassis sliding-scale approach—where development time is tied to championship standings—should govern power unit parity, too.

Why it matters:

• The ADUO framework determines which 2026 power unit manufacturers can upgrade otherwise homologated designs. Tying those freedoms to kilowatt deltas rather than on-track results risks misaligning engine metrics with actual grid competitiveness.
• Binotto's proposal would give new entrants like Audi a clearer, standings-driven path to close the gap without relying solely on dyno figures.

The Details:

• The FIA currently plans to benchmark internal combustion engine output and award ADUO rights to the four manufacturers trailing the benchmark unit.
• Binotto told media that using "delta kilowatts" as the sole metric is debatable when the sport already allocates wind tunnel and CFD resources based on championship position.
• He suggested leveraging existing car sensors to validate real-world performance, then applying a sliding scale based on previous season results to determine upgrade eligibility.
• This would create what he calls a "unique system framework" where both chassis and power unit regulations follow the same sporting logic, preventing benchmark leaders from locking in permanent advantages.

What's next:

• Confirmation of which manufacturers receive 2026 ADUO status remains outstanding from the FIA.
• While Binotto stressed trust in the governing body's current process, he indicated future regulations should move toward a single, championship-based convergence tool that mirrors the proven chassis model.
