Red Bull Demands FIA Recheck After ADUO Names Its Engine the Benchmark

Overview

• The FIA’s new ADUO process provisionally found Red Bull Powertrains‑Ford to have the strongest internal combustion engine, a result that stops Red Bull from making further ICE upgrades under current rules.
• Red Bull says it is exchanging data with the FIA and has asked for a formal recheck of in‑car torque‑sensor readings that underlie the ADUO measurements.
• The ADUO metric measures only pure ICE torque via standardized onboard sensors and does not account for hybrid systems, battery energy or ERS control, which leaves overall car performance outside the assessment.
• Rivals including Mercedes, Ferrari, Audi and Honda have begun using their provisional ADUO allowances to plan limited dyno work and upgrade paths, gaining extra homologation slots, testing hours and scaled cost‑cap leeway.
• The FIA has not confirmed final rankings and further review windows are scheduled before the summer break and at later GPs, so the outcome will determine whether midseason developments already started by rivals stand or must be revised.
