Mercedes reveals reason for Russell retirement in Montreal

Mercedes left the Canadian Grand Prix with a blend of pride and frustration after a dramatic afternoon that saw Andrea Kimi Antonelli take his fourth consecutive victory while George Russell retired from the race lead with a technical failure.

Trackside Engineering Director Andrew Shovlin described the weekend as one of “mixed feelings,” praising the team’s pace but acknowledging the heavy cost of Russell’s retirement.

Russell started from pole but suffered a slow launch, losing out to both Antonelli and Lando Norris. Once Norris pitted early, Antonelli was released into clean air — but Russell quickly fought back, retaking the lead. What followed was one of the most intense intra‑team battles of the season: both drivers locked up, ran wide, went side‑by‑side, and came close to contact multiple times, yet the fight remained clean and respectful.

The lead changed hands repeatedly, with Antonelli appearing slightly faster while Russell was tidier and more precise. The duel looked set to continue until the final laps — until Russell suddenly slowed and pulled off the track, visibly furious as he hit his car in disbelief. Mercedes later confirmed that the issue originated in the battery pack.

Antonelli went on to win comfortably, extending his championship lead over Russell to 43 points.

After the race, Shovlin summarised the team’s emotions, saying: “We come away from Montreal with mixed feelings. Well done to Kimi and the team for the win, our fifth to start this year and Kimi's fourth, but the failure on George's car is bitterly disappointing.

"We will work hard to make sure we understand the cause as it's been very costly for him and the team in terms of points.”

He explained that the cold, windy conditions made tyre behaviour unpredictable: “The cold and windy conditions made the race challenging today. We didn't have any idea how the tyres would behave with such a low ambient and track temperature.

"The warm‑up was certainly difficult but once up to temperature the tyres were working quite nicely. We were also able to quickly identify that the one‑stop strategy was the best option.”

Shovlin admitted that watching Russell and Antonelli fight so closely was nerve‑wracking: “It wasn't particularly relaxing watching our pair race in the first stint; the advantage of the overtake mode meant the cars could not separate so they were locked in a duel for the first 30 laps.

"Whilst it was close, they gave each other room. It did cost them both race time but the advantage over their competitors was enough for them not to be threatened.”

He then confirmed the nature of Russell’s retirement: “That fight was brought to an abrupt halt with George's car coming to a stop with an issue in the battery pack.

"We don't have any more information on that at the moment, but it goes without saying we'll be doing everything we can to understand that ahead of the next race.”

Once Russell retired, Antonelli had a clear path to victory. Shovlin explained: “Thereafter, Kimi's run to the finish was quite straightforward.

"We seemed to have a bit of a pace advantage over our competitors, although the margins are small and everyone is developing at such a rate that we will be trying to bring every bit of performance we can to the upcoming races.”
