The Mercedes pit wall explains how Andrea Kimi Antonelli’s Canada win became easier than expected. Inside the Mercedes strategic puzzle before George Russell’s brutal DNF.

George Russell’s retirement in Montreal dramatically changed the course of the race for Mercedes, but paradoxically, it also made life much easier for the team’s strategists. The big unanswered question is what would have happened in the battle with McLaren and in the pit-stop window had Russell remained in contention.

The first key strategic decisions were made before the race had even truly begun. When Pirelli communicated McLaren’s tyre choices for the start, Mercedes engineers initially thought there had been a mistake, as Lando Norris and Oscar Piastri were the only front-runners to line up on intermediate tyres.

“That was a crazy decision. We never discussed anything other than slicks,” a strategy engineer reportedly told Auto Motor und Sport, underlining the surprise on the Mercedes pit wall when it became clear that their rivals had effectively removed themselves from the fight at the front.

McLaren’s gamble changed the race immediately

McLaren’s risky tyre call allowed both George Russell and Andrea Kimi Antonelli to pull clear and maintain control, even while battling each other on track.

Under the new energy management regulations, drivers lose even more time when fighting wheel-to-wheel, but in this case Mercedes’ advantage remained stable enough for team principal Toto Wolff to avoid issuing team orders.

The original race plan involved a two-stop strategy, but the conditions—particularly the unusually smooth asphalt and cool temperatures—significantly reduced tyre degradation. Mercedes therefore revised its approach and switched to a one-stop strategy, targeting the first pit window around lap 10.

The tactical battle with Max Verstappen

The most delicate strategic element revolved around timing the pit stop against Max Verstappen: “So we simply waited for Verstappen to stop first. As long as we were ahead of him, there was no risk,” Mercedes engineers explained.

Because George Russell was experiencing slightly higher tyre wear, he would most likely have been the first Mercedes driver to pit, with Andrea Kimi Antonelli following shortly afterwards.

But the decision would not have been straightforward: “Because of the longer warm-up phase, it would have become an overcut race. If Kimi had stopped immediately one lap after George, he probably would have come out ahead of him despite having colder tyres. Then George would have attacked immediately with more tyre temperature.”

A team headache that never happened

Mercedes strategists openly admitted that whichever decision they made would likely have favoured one driver over the other, meaning difficult conversations would almost certainly have followed after the race: “We would have had to explain the decision to the drivers afterwards anyway.”

But that potential tactical thriller never unfolded. George Russell’s retirement on lap 29, followed by the Virtual Safety Car, effectively removed the problem for Mercedes and handed the team a far cleaner strategic scenario.

The practical outcome was simple: Andrea Kimi Antonelli was able to manage the race comfortably to the chequered flag and secure his fourth victory of the 2026 Formula 1 season with relative ease.
