Car Presentation – 2026 Canadian Grand Prix *Mercedes-AMG PETRONAS F1 Team* Updated component Primary reason for update Geometric differences compared to previous version Brief description on how the update works (min 20, max 100 words) 1 Front Wing Performance - Flow Conditioning Front wing outboard elements dropped in height and run into the footplate. Running the front wing elements into the footplate, and adding strakes, results in more robust flow structures, improving flow to the rear of the car and gaining downforce. 2 Front Wing Endplate Performance - Flow Conditioning Front wing endplate and footplate adjusted to accommodate the above. Footplate stakes added. Diveplane camber adjusted. 3 Front Corner Performance - Flow Conditioning Front caketin upper lip camber reduced. Reduced upper lip camber improves flow structure robustness throughout the operating envelope, improving the onset flow to the rear wing. 4 Front Corner Circuit specific - Cooling Range Increased inlet and exit size. Due to the high braking demands of Montreal - increasing the duct inlet and exit size increases mass flow feeding the discs resulting in more cooling. 5 Floor Board Performance – Local Load Reprofiled elements Reprofiled elements to improve local pressure distribution and reduce separations at the extremes of the operating envelope, resulting in increased local load. 6 Floor Corner Performance - Flow Conditioning Additional slots Re-optimisation of floor corner slot arrangement to both increase local load and to also improve flow into the diffuser and hence rear load. 7 Floor Body Performance – Local Load Reprofiled diffuser roof By reprofiling the diffuser roof and sidewall we improve the surface flow quality throughout the operating envelope and generate more local load. 8 Rear Corner Performance – Local Load Rear winglet span and position redistribution Chord and position of the rear caketin winglets re-optimised to improve local flow control and performance of the diffuser. Car Presentation – Canadian Grand Prix Oracle Red Bull Racing. Updated component Primary reason for update Geometric differences compared to previous version Brief description on how the update works (min 20, max 100 words) 1 Front Wing Balance Range Revised front wing flap elements Both second and third front wing elements forming the flap assemblies are revised to shift the aerobalance range available for the upcoming circuits. 2 Front Corner Reliability Revised brake duct exit geometry The next two circuits on the calendar demand more brake assembly cooling and to offer this an enlarged exit duct has been produced to enhance the cooling 3 Floor Performance – Local load Bib edge trim and revised forward floor devices To further optimise both the bib and forward floor devices, the former has a trim applied and the latter mildly increased camber resulting in the local load increasing 4 Engine Cover Reliability Cooling exit panel option Given the forecast for Montreal, a closed radiator exit panel has been created with the louvre steps necessary for the race in Miami now closed. Car Presentation – Canadian Grand Prix SCUDERIA FERRARI HP No updates submitted for this event. Car Presentation – Canada Grand Prix *Williams* Updated component Primary reason for update Geometric differences compared to previous version Brief description on how the update works (min 20, max 100 words) 1 Front Corner Circuit specific - Cooling Range A new FBD scoop geometry with a reprofiled exit area. To suit the demands of the Gilles-Villeneuve circuit, a new FBD geometry will be introduced which offers an increased level of overall brake system cooling. 2 Front Suspension Performance - Flow Conditioning Revised suspension cladding surfaces, with changes in chord and incidence across their span. In concert with the updated FBD geometry, new suspension cladding will be available to improve the local interactions on the front corner and hence downstream across the rest of the car. 3 Exhaust Tailpipe Performance – Local Load A repositioned exhaust tailpipe Following on from an update introduced at the previous Miami GP, a further step on the exhaust system will be evaluated which offers an improved coupling with the surrounding aerodynamic components. Car Presentation – Canadian Grand Prix Visa Cash App Racing Bulls Updated component Primary reason for update Geometric differences compared to previous version Brief description on how the update works (min 20, max 100 words) 1 Floor Body Performance - Local Load New Main Floor geometry A new floor geometry resulting in an efficient downforce increase generated by the underbody of the car, across a range of operating conditions. 2 Rear Corner Performance – Flow Conditioning Reprofiled Rear Corner devices Working in conjunction with the floor update, the changes to the rear corner devices improve the flow management at the back of the car. 3 Beam Wing Performance – Local Load Profile and incidence modifications Supporting the changes made to the floor and around the exhaust, the Beam Wing changes help extract additional load from the rear wing assembly. 4 Exhaust Tailpipe Bracket Performance – Flow Conditioning Reprofiled tailpipe bracket The tailpipe bracket update improves the flow management around the centreline of the car as part of the surrounding changes on the Beam Wing and floor.

Car Presentation – Canadian Grand Prix HAAS Updated component Primary reason for update Geometric differences compared to previous version Brief description on how the update works (min 20, max 100 words) 1 Sidepod Inlet Performance - Flow Conditioning Revised Sidepod Inlet 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. 2 Coke/Engine Cover Performance - Flow Conditioning Undercut and top downwash 3 Floor Body Performance - Local Load Revised floor geometry, with new floor board, new floor edge splits and a more aggressive diffuser promoting up- and side-wash The new floor was developed in conjunction with the updated bodywork. Its geometries are optimised to guide higher‑energy airflow through the floor volume, enhancing mass flow and stability, and promoting more efficient extraction and overall load generation. 4 Rear Suspension Performance - Flow Conditioning Optimized suspension faring design The updated floor and bodywork required a realignment of the suspension fairings, enabling improved flow conditioning in this region and extracting additional performance from the overall package. 5 Rear Corner Performance - Local Load Revised winglet geometry on the inboard drum face The modified incoming flow field required a realignment of the inboard drum devices to maintain their aerodynamic effectiveness and ensure consistent performance within the updated overall flow conditions.
