Technical updates: 2026 Canadian Grand Prix

Mercedes and McLaren have both brought substantial upgrades as the development race continues at the Canadian Grand Prix.

The dominant team in the early part of the season, Mercedes did not significantly update its car in Miami as the rest of the chasing pack closed in. In Montreal, the first package has been brought by Toto Wolff’s team, with a new front wing, front corner, rear corner and floor. As part of the extensive floor change, Mercedes says that by “reprofiling the diffuser roof and sidewall we improve the surface flow quality throughout the operating envelope and generate more local load.”

There is also an increase in size of the front brake duct inlets for cooling purposes, that the team says is a circuit-specific change.

McLaren continues its development program with a further package on top of its Miami work. The new components include a new front wing, revised bodywork package, additional winglet on the halo, updated floor edges, rear wing endplates, and rear suspension fairings. There are also additional cooling louvers in the bodywork for circuit-specific purposes in Montreal.

Red Bull has submitted four new components, of which two are for cooling reasons. Revised brake ducts and engine cover cooling exit panels are based on the braking demands and weather forecast in Canada, but there is an updated front wing and floor for performance gains.

At Williams, revised front suspension fairings and a repositioned exhaust tailpipe are deemed upgrades, while also adding a brake duct change for cooling reasons. Racing Bulls also has tweaked its tailpipe bracket to go in tandem with a new floor, beam wing and rear corner devices.

Another more significant update is brought by Haas – a team, like Mercedes, that did not deliver one in Miami – and includes an entirely new floor, revised sidepod inlets, optimized rear suspension fairings and upgraded winglet geometry on the inside of the rear brake drum.

On the bodywork changes, Haas says: “The revised bodywork enables a more pronounced undercut along the lower surfaces, which, combined with increased top‐surface downwash, channels higher‐energy airflow towards the rear of the car, allowing the bespoke floor design to operate more efficiently.”

Audi has a new diffuser design on top of cooling solutions on its bodywork and brake ducts, while Alpine is introducing a new floor and rear wing this weekend. Like Audi, Cadillac similarly has a revised diffuser and updated front brake ducts for improved cooling capacity.

There are no new components submitted by Ferrari or Aston Martin.
