Mercedes and McLaren rolled out extensive upgrade packages at the Canadian Grand Prix, aiming to close the gap on their rivals. McLaren unleashed the second phase of its two-part development plan, initiated in Miami, introducing a brand-new front wing designed for better flow conditioning and improved aerodynamic load. Further changes include a re-profiled engine cover with optimized cooling exits, a new halo fairing, revised suspension fairing, and tweaks to the rear wing endplates and floor edge, all geared towards boosting downforce.
Mercedes debuted its major spring upgrade, focusing on a new front wing with a more integrated mainplane and strakes for robust flow structures, funneling air to the rear and generating downforce. The W17 also received revisions across most of its floor and tweaks to its winglets. Red Bull brought minor floor updates and specific front wing flap adjustments for Montreal. Ferrari, having deployed its major parts in Miami, stood pat. These upgrades intensify the development race, setting the stage for a tight battle on the Circuit Gilles Villeneuve.
