George Russell is also expected to take a Formula 1 grid penalty for exceeding his power unit allocation before the end of the 2026 season, adding to Mercedes’ reliability problems after Toto Wolff confirmed that Kimi Antonelli will already take his own penalty at Monza. Mercedes is still discussing which circuit would offer Russell the best opportunity to absorb the inevitable setback while limiting the damage to its championship campaign.
The reliability issues encountered by Mercedes during the first half of the season are now beginning to carry a significant sporting cost. It is already known that championship leader Kimi Antonelli will start from the back of the grid at the Italian Grand Prix after Toto Wolff’s team decided to replace his entire power unit at Monza.
Mercedes hopes the long, extremely fast straights of the ‘Temple of Speed’ will give the young Italian a better chance of recovering positions and minimising his championship losses. The team is also considering how best to exploit its engine performance at a circuit where Mercedes’ power unit update could help Kimi Antonelli overcome his Monza grid penalty.
George Russell will also need Mercedes power unit penalty
Speaking to reporters in the press conference after the race at Zandvoort, Toto Wolff confirmed that George Russell will have to deal with a similar situation at some point during the remainder of the season.
The British driver currently sits second in the Drivers’ Championship, level on points with Lewis Hamilton and 59 points behind Mercedes team-mate Kimi Antonelli. That makes the choice of where to take the penalty particularly important as Mercedes attempts to maximise its points haul in both championships.
“With Kimi Antonelli we will change the entire power unit,” Toto Wolff explained. “In theory, our calculations tell us that [Monza] is the best track at which to take penalties. Obviously, the ‘algorithms’ don’t take the driver’s nationality into account, but with a World Championship at stake, we have to try to score as many points as possible.”
“With George Russell, meanwhile, discussions are still ongoing about where to take it [the penalty].”
Baku emerges as possible option for George Russell
One possibility could be Baku. The Azerbaijan Grand Prix had initially also been considered as an alternative to Monza for Kimi Antonelli before Mercedes eventually ruled it out in favour of taking the Italian’s penalty at his home race.
While the location remains under discussion for George Russell, what now appears increasingly certain is that the driver of the number 63 Mercedes will need to use an additional power unit beyond the number permitted under the regulations before the season concludes.
The prospect is another consequence of the reliability difficulties Mercedes has experienced this year. Earlier in the season, the team also had to investigate a power unit fault behind George Russell’s performance problems, highlighting the strain placed on the available component pool.
Mercedes reliability could complicate 2026 title fight
The timing of the penalties matters because Mercedes is fighting at the sharp end of both championships. Kimi Antonelli’s advantage gives the team some room to manage his Monza setback, but an additional penalty for George Russell could further complicate the closing stages of the season.
The situation also comes as Mercedes faces increasing pressure from its rivals. Recent reliability problems have already contributed to the concern over whether George Russell’s points deficit could affect Mercedes in the Constructors’ Championship battle.
Monza’s layout makes it an attractive venue for serving a power unit penalty because overtaking opportunities and high straight-line speeds can improve a driver’s chances of recovering from the back of the grid. Engine performance is set to be particularly important at the Italian Grand Prix, with Ferrari also preparing a planned Monza power boost for its home event.
Mercedes’ calculations do not, however, account for possible further accidents or technical failures between now and the end of the season. With 2026 representing the first year of an entirely new Formula 1 technical regulation cycle, unexpected reliability problems remain an ever-present risk and could force the team to revise its plans once again.
