George Russell has revealed that Mercedes is deliberately postponing his Formula 1 engine penalty until the team is ready to introduce its next ADUO power-unit upgrade. The Mercedes driver confirmed the strategy during media activities ahead of the Spanish Grand Prix in Madrid, making it clear that the timing of the penalty is being carefully planned rather than avoided.
Under the 2026 regulations, each driver is permitted a maximum of four internal combustion engine (ICE) components. Exceeding that allocation triggers a 10-place grid penalty, although drivers can continue moving between components already included in their pool without receiving another sanction. Mercedes reached its four-engine limit at Monza, where Kimi Antonelli chose to take his penalty
at his home event.
Russell explained that taking his own penalty in Madrid without the new engine would have been pointless. Mercedes instead intends to combine the grid drop with the introduction of his fifth engine, allowing the team to maximise the benefit of the additional power-unit upgrade. The decision highlights how teams are increasingly having to think strategically about when penalties are most worthwhile under the new regulations.
The ADUO system — Additional Development and Upgrade Opportunities — was introduced by the FIA alongside the 2026 regulations. It monitors the performance gap between manufacturers’ internal combustion engines and the benchmark power unit. Teams falling 2–4 percent behind the leading benchmark can receive an additional engine upgrade, while those more than 4 percent behind can qualify for two. Although Mercedes has been highly competitive overall, Red Bull’s engine was judged to be the benchmark, leaving Mercedes eligible for an upgrade.
Russell’s comments therefore strongly suggest that Mercedes expects its ADUO upgrade to arrive soon, with the team choosing to coordinate it with his unavoidable engine penalty. Rather than sacrificing a grid position without gaining anything in return, Mercedes appears determined to turn the setback into an opportunity by debuting the upgraded power unit at the same time.
