McLaren’s Shorter Gears Cost Norris 0.151 s to Russell in Canada

*TL;DR: Lando Norris finished 0.151 seconds slower than pole‑sitter George Russell at the Canadian Grand Prix because McLaren ran shorter gear ratios; team principal Andrea Stella says the setup will stay unchanged.

Context The Montreal circuit highlighted a technical gap between McLaren and Mercedes for the 2026 season. Both teams use the same Mercedes power unit, but McLaren designs its own gearbox, allowing it to select gear ratios independently. Shorter ratios shift the car into a higher gear earlier, affecting acceleration and top‑speed sections differently.

Key Facts McLaren’s gear choice meant Norris reached a higher gear three times around the lap and shifted up earlier on acceleration zones. The trade‑off manifested on the long straight from Turn 10 to the final chicane, where the shorter ratios reduced top‑end speed, costing Norris 0.151 seconds to Russell’s pole‑lap Mercedes. Andrea Stella acknowledged the mixed impact, noting that the ratios can boost launch and straight‑line acceleration but hinder performance on the longest straights. He confirmed the team is “happy with where we are” and will not pursue the mid‑season ‘joker’ adjustment that regulations permit.

What It Means The data suggests McLaren prioritized acceleration over outright top speed, a strategy that may pay off on circuits with tighter layouts or frequent corner exits. Retaining the current ratios signals confidence that the acceleration gains outweigh the straight‑line loss across a typical season calendar. Observers will watch how the setup performs on tracks like Silverstone or Spa, where long straights dominate, to gauge whether the compromise remains viable.

Looking Ahead The next test of McLaren’s gear philosophy will come at the upcoming European rounds, where the balance between acceleration and top speed will be under scrutiny.
