George Russell is preparing to take another hit on the starting grid, with Mercedes’ long-awaited power unit upgrade set to arrive at a time when the Silver Arrows may need every advantage they can find against a resurgent Red Bull.
The Briton expects to receive the new-spec engine component next month, potentially at the Las Vegas Grand Prix in November, with the change set to trigger another grid penalty after his recent reliability troubles forced him to start last in Singapore.
Mercedes had originally planned to introduce the new hardware at next weekend’s United States Grand Prix in Austin. However, Russell’s power unit problems in Malaysia, where an engine issue forced his retirement late in the race, have seemingly altered those plans.
Russell eyes a strategic penalty
Speaking to Sky Sports F1, Russell acknowledged that Mercedes now has greater flexibility over when to introduce the upgrade, thanks to the FIA’s Additional Development and Upgrade Opportunities (ADUO) system.
“It will probably be later in the season now to be honest - maybe Las Vegas. But it will be there at some point,” he said when asked about the timing of the change.
“Now we have the choice to take it when we wish and we will choose slightly easier tracks [to overtake at].”
That suggests Mercedes will look beyond outright performance when deciding where to take the penalty, favouring circuits where Russell can recover lost positions rather than sacrificing valuable track position at venues where overtaking is more difficult.
The ADUO provisions give Mercedes an opportunity to improve its power unit following the FIA’s assessment that its engine performance falls behind that of some rivals.
The classification has proved contentious, particularly with Red Bull disputing the suggestion that Mercedes needs additional development opportunities while continuing to dominate the Constructors’ Championship.
Red Bull’s surge adds urgency
The timing of the upgrade could prove significant.
Mercedes entered 2026 with Russell widely tipped as a title contender, but the Briton has struggled to match second-year team-mate Kimi Antonelli, who has claimed eight victories to Russell’s three and now leads him by 102 points with six rounds remaining.
Meanwhile, Max Verstappen has emerged as an increasingly formidable threat.
After Mercedes introduced an upgrade package in Malaysia without achieving the immediate gains it expected, the team split its specifications in Singapore, with Russell using the older configuration and Antonelli running the revised package.
Verstappen dominated the competitive sessions across Singapore’s Sprint weekend, while Russell crashed out of the Sprint after leading the race. The Dutchman’s recent performances have left Mercedes searching for answers.
“The goal right now is to try to improve the car. We were very much the dominant team for this whole season,” Russell said.
“You look at the recent races and Red Bull have been very much best. In Baku, Max was a similar level to me. We go to Malaysia, a totally different track, and Singapore another different track, and he's dominated the last two weekends.
“Right now, the goal is to try and get on top of these updates.”
Mercedes will hope the engine upgrade can help reverse that momentum.
But with Russell already paying the price for one power unit change, the team faces a delicate calculation: finding the right moment to take another penalty while ensuring the performance gain is worth the sacrifice.
