James Vowles confirms Mercedes ADUO loophole impacts F1 regulations

Williams Team Principal James Vowles confirmed that a recent FIA ruling regarding Additional Development and Upgrade Opportunities (ADUO) has favored Mercedes over Red Bull. The ruling restricts Red Bull’s engine development while allowing Mercedes extra budget for upgrades. Vowles highlighted the loophole in the assessment, which favors the Internal Combustion Engine (ICE) and overlooks the crucial role of the electrical Energy Recovery System (ERS). He noted that Williams stands to benefit from Mercedes’ advancements due to their partnership. Looking ahead, Vowles expressed optimism about the potential rebalancing of power unit regulations planned for 2027.
