No.	Updated component	Primary reason for update	Geometric differences	Description
1	Front Wing	Performance - Flow Conditioning	New Front Wing	A new front wing design, aimed at better flow conditioning across the operating range resulting in improved aerodynamic load delivery.
2	Coke/Engine Cover	Performance - Flow Conditioning	New Bodywork	A revised bodywork package featuring additional cooling exits aiming at improved aerodynamic flow conditioning towards the rear of the car.
3	Cooling Louvres	Circuit specific - Cooling Range	Cooling Louvre Options	As part of the new bodywork package, multiple cooling louvre options are available to cover the full range of ambient temperatures expected at this and future events.
4	Halo	Performance - Flow Conditioning	Halo Winglet	A new winglet on top of the halo, aiming at improved management of aerodynamic flow around the cockpit and central engine cover.
5	Rear Wing Endplate	Performance - Local Load	Revised Rear Wing Endplate	Modification to the rear wing endplate geometry resulting in a change in load distribution and increase in local aerodynamic load.
6	Rear Suspension	Performance - Flow Conditioning	Revised Rear Suspension Fairings	Small modification to the rear suspension fairings aimed at improved aerodynamic flow conditioning and load generation around the rear corner and diffuser.
7	Floor Edge	Performance - Flow Conditioning	Revised Floor Edge Devices	Iteration on floor edge devices aimed at improved overall floor conditioning and aerodynamic load generation on the floor and diffuser.

No.	Updated component	Primary reason for update	Geometric differences	Description
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.

No.	Updated component	Primary reason for update	Geometric differences	Description
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.

No.	Updated component	Primary reason for update	Geometric differences	Description
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

No.	Updated component	Primary reason for update	Geometric differences	Description
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.

No.	Updated component	Primary reason for update	Geometric differences	Description
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,
2	Coke/Engine Cover	Performance - Flow Conditioning	Undercut and top downwash	channels higher‑energy airflow towards the rear of the car, allowing the bespoke floor design to operate more efficiently.
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 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 overall flow conditions.
