Technical updates: 2025 Canadian Grand Prix

McLaren and Mercedes both have potentially significant updates to their cars at the Canadian Grand Prix.

On a flyway weekend that rarely sees major new developments introduced, McLaren has a new front wing – that includes the introduction of what the team are calling "mermaid tails" to the front wing endplate – and front suspension. There is also a circuit-specific rear wing change that covers a wider drag range and will be suitable for a number of venues.

At Mercedes, an update to the floor edge is designed to increase mass flow under the forward floor, and lead to an overall increase in floor load. There is also a new brake duct configuration that the team says is specific to the cooling requirements in Montreal.

Aston Martin similarly has an enlarged front brake duct exit for the Circuit Gilles Villeneuve, while a new front wing at Alpine is also designed to offer less load due to the track demands.

There is a similar front wing solution at Racing Bulls for this weekend, but a performance upgrade has also been introduced on the rear corner, with a revised lower winglet endplate shape that will help increase rear downforce.

Ferrari, Red Bull, Haas, Williams and Sauber have not submitted any new components for this weekend’s race.
