Mercedes defends F1 engine rules amid Red Bull frustrations

Summary

Mercedes is vocal in support of the FIA's new Additional Development and Upgrade Opportunities (ADUO) framework for the 2026 F1 season, which has sparked significant political tension within the sport. Mercedes Vice Team Principal Bradley Lord emphasized that the regulations are intended to balance engine performance, but have inadvertently hindered Red Bull Powertrains by enforcing a 'benchmark' status that restricts their development. As Red Bull grapples with this limitation, Mercedes looks to enhance its W17 chassis without disclosing specific upgrade timelines. Lord also dismissed rumors of 'sandbagging' from his team, reinforcing that the complexities of the new regulations make such strategies unfeasible.
