Car Presentation – Belgian Grand Prix

McLaren Mastercard F1 Team

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Rear Wing	Performance - Flow Conditioning	Endplate modification	A small revision to the rear wing endplate resulting in improved flow conditioning and aerodynamic characteristics across the full operating range.
2	Rear Wing	Circuit Specific – Drag Reduction	New Rear Wing assembly	A new rear wing assembly specifically designed for the increased isochronal of this circuit, resulting in an efficient reduction of drag in straight line and cornering mode.

Mercedes-AMG PETRONAS F1 Team

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Rear Wing	Circuit specific - Drag Range	Reduce camber upper wing elements The upper wing element camber has been reduced to drop local downforce and drag at a level appropriate for Spa L/D.
2	Rear Corner	Performance - Local Load	Rear drum winglets position and span	Rear drum winglets position and span optimised around evolving onset flow and local load requirements – improved robustness through operating envelope.
3	Front Wing Endplate	Performance - Flow Conditioning	Endplate top edge camber increased	Endplate top edge camber increased to improve front wing performance throughout the operating envelope, improving onset flow to the rear of the car.

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Rear Wing	Performance - Local Load	Revised pylon profiles	Given the pylons now by regulation contact the mainplane underside, the interface is sensitive and revised with pylon changes to existing element profiles seeking to extract more load and at least maintain flow stability.

Williams

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Rear Corner	Circuit specific - Drag Range	A revised rear brake duct winglet array	To suit the demands of the Spa-Francorchamps circuit, we have reduced the loading on the rear corner which offers a local efficiency improvement.
2	Floor Body	Circuit specific - Drag Range	A local trim has been applied to the main Floor Body	A further circuit specific change, altering the balance between downforce and drag at the rear of the main floor.
3	Floor Body	Performance - Flow Conditioning	An updated main floor profile which adds volume to the central part of the diffuser.	To change the distribution of diffuser expansion volume across the car operating envelope, a new floor body surface has been introduced.

Visa Cash App Racing Bulls

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Coke/Engine Cover	Performance – Flow Conditioning	Updated sidepod & upper bodywork	The profile of the sidepods has been modified to provide better control of the airflow passing around the side of the car.
2	Roll Hoop	Performance – Flow Conditioning	Revised roll hoop inlet shape	A narrower roll hoop has been introduced, which improves the flow quality reaching the back of the car and on to the rear wing.
3	Front Corner	Performance – Flow Conditioning	Updated brake drum assembly	Detail changes on the front brake drum management at the front of the car.
4	Rear Wing	Performance – Local Load	New upper rear wing assembly	A number of changes to the mainplane and flap profiles allow the rear wing to generate downforce more efficiently, bringing performance improvement at Spa and other circuits.

TGR HAAS F1 TEAM

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Front Wing	Performance - Local Load	Revised Profiles and Pylon geometry	A revised Front Wing geometry has been introduced to increase local aerodynamic load while maintaining aerodynamic efficiency, improving airflow management and overall front end performance across a range of operating conditions.
2	Front Wing Endplate	Performance - Flow Conditioning	Revised Endplate geometry	A revised Front Wing endplate geometry has been profiles, optimising local airflow control and maintaining aerodynamic efficiency across the front wing assembly.
3	Front Corner	Performance - Local Load	Marginal geometry changes to deflector	A circuit-specific Front Corner configuration has been made available, providing additional flexibility to better match the aerodynamic load requirements of this circuit.
4	Beam Wing	Performance - Drag reduction	Revised lower Rear Wing geometry	A new Lower Rear Wing configuration has been introduced as a circuit-specific option, providing additional flexibility to align the car’s aerodynamic characteristics with the demands of this venue and optimise overall performance.
