Mercedes brings its first big 2026 upgrade to Montreal

Mercedes’ first major upgrade of the 2026 Formula 1 season has arrived ahead of the Canadian Grand Prix. While rivals Red Bull, McLaren, and Ferrari introduced significant packages in Miami, Mercedes held back, opting for more development time on what is expected to deliver a good performance gain. Both Kimi Antonelli and George Russell will run the full suite from FP1, with sprint qualifying immediately following—leaving minimal time for optimization.

Why it matters:

Mercedes’ decision to delay its upgrade in a tight field underscores its focus on long-term development. The package aims to address aerodynamic consistency and downforce, key areas where the team has struggled relative to the frontrunners. Success here could reshape the competitive order at a circuit that demands strong mechanical grip and braking stability.

The details:

• Front wing: Outboard elements dropped in height and run into the footplate; endplate and footplate revised with added strakes and adjusted diveplane camber. Goal: more robust flow structures and improved rearward airflow quality.
• Front corner: Upper lip camber of the cake tin reduced to enhance flow structure robustness across the operating envelope, aiding rear wing performance.
• Brake ducts: Inlet and exit enlarged for Montreal’s high braking demands.
• Floor updates: Floorboard reprofiled to improve local pressure distribution and reduce separations at extremes; additional slots in floor corners to increase local load and improve diffuser flow.
• Floor body: Reprofiled diffuser roof and sidewall changes to generate more load from the floor over a wider range of conditions.
• Rear corner: Rear cake tin winglets re-optimized in chord and position for better local flow control and diffuser performance.

What’s next:

With only one practice session before sprint qualifying, Mercedes faces a tight window to calibrate the new parts. The team will rely heavily on simulation data to hit the ground running. If the upgrade delivers as expected, Montreal could mark a turning point in its 2026 campaign.
