George Russell secured pole position for the Sprint at the Canadian Grand Prix, but beyond the headline result, Sprint qualifying in Montreal delivered some particularly interesting technical insights. The session offered the first real competitive look at the significant upgrades introduced by Mercedes, while McLaren also arrived with new developments for the MCL40, sharing the same power unit architecture as the Brackley team.
Canadian GP: Montreal proves ideal for the W17 while Ferrari still faces energy limitations
As expected heading into the weekend, Circuit Gilles Villeneuve remains a track that is highly sensitive to power output, thanks to its long straights and repeated acceleration zones from low-speed corners. In this environment, electric deployment becomes critically important, as teams must carefully manage energy delivery to maximise traction zones and straight-line efficiency.
Based on what was observed in the sole free practice session, Ferrari’s SF-26 appeared to be lacking in precisely that area, while Mercedes immediately looked comfortable with its new upgrade package, which seems to have delivered a clear increase in aerodynamic load. Ferrari, on the other hand, appears to have made a meaningful step forward in terms of overall balance between FP1 and Sprint qualifying, with the team still continuing to work through the updated package first introduced in Miami.
Lewis Hamilton’s first sector in SQ3, on his second attempt with the C5 Soft tyre, was certainly one of the most encouraging signs for Ferrari. Analysing the telemetry from the best laps of George Russell, Lando Norris, and Lewis Hamilton, the British Ferrari driver was able to gain time in the medium-to-slow corner entry phases of Sector 1, particularly by braking later into Turn 3 than his direct rivals.
In addition, during the very early phase of corner exits from those medium-slow sections, the SF-26 showed impressive stability, likely allowing Ferrari to exploit the advantages of its smaller-radius turbocharger concept.
Mercedes power advantage becomes obvious
Between Turns 7 and 8, however, the strength of the Mercedes power unit became unmistakably clear, with the speed differential between Lewis Hamilton and George Russell approaching 10 km/h. A similar pattern emerged between Turns 9 and 10, where despite the relatively short acceleration zone, George Russell still managed to increase the gap by around one tenth of a second.
Then, along the longer run between Turns 10 and 13, the speed gap between the two narrowed to somewhere between 2 and 5 km/h, suggesting Ferrari may have been searching for a compromise setup to remain reasonably competitive on the straights without completely sacrificing other areas.
McLaren, with Lando Norris, appeared to adopt a more intermediate energy deployment strategy, consistent with what has been seen throughout the season. Between Turns 7 and 8, the reigning world champion lost approximately 5 km/h compared to Mercedes, then remained closer on the following straight before losing around 10 km/h on the final major acceleration zone.
There remains obvious frustration for Ferrari over Lewis Hamilton’s mistake at Turn 10, which compromised the corner exit and the remainder of the lap. Of the roughly three-and-a-half tenths lost to George Russell, a substantial portion appears attributable to Ferrari’s top-speed shortcomings—whether due to a power unit deficit or potentially excessive aerodynamic drag.
Mercedes progress looks significant
Mercedes’ step forward remains particularly striking. George Russell produced a sector through the Turns 8-9 chicane that was very close to Lando Norris, despite the McLaren traditionally being strong in such sections.
That said, context matters. The C5 Soft tyres used in SQ3 had already completed an earlier attempt, meaning tyre confidence and degradation likely played a role in the final pace differences. Ferrari, in particular, continues to appear less effective at extracting the maximum from the softest compound in the closing moments of qualifying.
Still, optimism remains inside Ferrari, especially in light of Lewis Hamilton’s own assessment: “It was one of my best qualifying sessions in a while. We tried a setup we had never used before, and it is definitely taking me in the right direction,” Lewis Hamilton said.
On the other side of the garage, Charles Leclerc endured a much more difficult session, affected by traffic and a lack of tyre temperature, factors that made his qualifying particularly complicated.
Will the Sprint race reduce the gaps?
Once the focus shifts from qualifying pace to race conditions, the competitive picture may change significantly. In qualifying sessions, the permitted rechargeable megajoule allocation per lap is limited to six, but in race conditions that increases to eight. That could further favour Mercedes’ already impressive power management, potentially creating even larger speed differentials on the long Montreal straights.
It is also worth remembering that maximum electrical power deployment in closed straight mode is capped at 200 kW, while between Turns 5 and 6 deployable electrical power can effectively drop to zero.
At this stage, Mercedes clearly appears to hold the advantage, helped significantly by the extensive upgrade package introduced in Canada, with further setup potential perhaps still untapped—as Andrea Kimi Antonelli himself hinted. McLaren, meanwhile, postponed the use of its updated front wing, preferring to maximise factory-to-track correlation under more suitable circumstances. Mercedes will also be watching its starts closely. The revised clutch paddle and updated software could prove crucial in addressing what has historically been one of the German team’s weakest areas.
Another factor to monitor will be tyre graining, especially considering the track surface conditions seen on Friday and the relatively low ambient temperatures in Montreal.
Mercedes’ aggressive technical development in Canada has therefore re-established the W17 as the car to beat, flexing both aerodynamic and power delivery muscle. While Ferrari looks to optimize its mechanical grip and smaller turbo advantages, and McLaren relies on its refined race deployment strategy, managing energy limits over longer stints remains the ultimate challenge. Sunday’s success will hinge entirely on whether the chasing pack can bridge this top-speed deficit or if Mercedes will seamlessly cruise to a dominant double podium.
