Car Presentation – Austrian Grand Prix

McLaren Mastercard F1 Team

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Rear Corner	Performance - Flow Conditioning	Revised Rear Brake Duct Inlet	The rear brake duct inlet has been revised, targeting an improvement in local flow conditioning and resultant gain in aerodynamic load generated around the rear corner.
2	Rear Wing	Performance - Drag reduction	Alternative Straight Line Mode Flap Position	The rear wing has been modified to deploy the flap to an alternative position in straight line mode resulting in a larger reduction in drag.

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Front Suspension	Performance - Flow Conditioning	Leg fairing angle of attack adjustment	Leg fairing angle of attacked adjusted to improve alignment to onset flow throughout ride height range, resulting in improved flow to the rear of the car.
2	Coke/Engine Cover	Cooling Range	Narrower rear exit A narrower rear exit allows more cooling range tuning, biasing more cooling flow to the louvres rather than the rear exit.

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Sidepod Inlet	Reliability	Revised sidepod inlet geometry extending downwards and rearwards	Optimised following earlier changes upstream the sidepod inlet has been re-profiled and re-positioned to capture air with good enough pressure for the radiators. This led to re-profiling to meet the floor.
2	Engine Cover	Reliability	Revised sidepod panels to meet the new inlet geometry then following the floor junction profile	Having altered the inlet, the consequence was then to re-optimise the sidepod profiles simultaneously Minor changes to the central engine cover and cooling louvres.
3	Floor Floor Board	Performance - Local Load Performance – flow conditioning	Subtle revisions to the surfaces including forward floor as well as the junction line with the topbody Subtle profile changes to the louvres and supports between	A further iteration of optimisation to compliment the new sidepod inlet, extending to the forward floor and then to the sidepod all to generate more local load and extract performance As part of the sidepod revision, a floor board change was also accomplished to offer another iteration of design to improve the downstream conditions for the sidepod and beyond.
4	Rear Suspension	Performance - Local Load	Reprofiled fairings and junctions to the tail/gearbox and into the rear wheel bodywork	Revisions to the fairings to better match the upstream conditions and maintain flow stability whilst extracting more local load.
5	Rear Corner	Performance - Local Load	Revised for the rear suspension fairings and attendant winglets	Primarily inboard of the rear wheels to accommodate the fairing revisions and blends into the wheel bodywork keeping the surfaces tidy whilst maintaining flow stability.

No.	Updated component	Primary reason for update	Geometric differences	Description
6	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 the same element profiles seeking to extract more load and at least maintain flow stability.
7	Exhaust Tailpipe	Performance - Local Load	Revised overlap between the tailpipe exit profile and the supporting tailpipe bracket	A subtle re-positioning of the tailpipe has enabled the last portion, which is regulated to circulated and within a limited angle range to have greater overlap with the one permitted supporting bracket to extract more local load.

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Front Wing Endplate	Performance - Local Load	Revised front wing endplate with new diveplane and new footplate vane arrangement	Further step applied to the new geometry introduced in the previous race in Spain, consolidating the original flow features and performance objectives of this front wing
2	RV Tail	Performance - Local Load	Removal of the central RV Tail element Free Practice test Item, not track specific and focused on data gathering and correlation exercise
3	Floor Board	Performance – Correlation	Front floor board elements optimisation, single vertical element Free practice test items, focused on aerodynamic correlation. Aim is to understand on-track behaviour and gather data in normal running conditions
4	Mirror stay		Shorter mirror vertical stay and connection to sidepod

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Exhaust Tailpipe	Performance – Flow Conditioning	Lowered tailpipe with new bracket	The tailpipe position helps with the flow management around the rear of the car, allowing the rear wing to perform efficiently.
2	Diffuser	Performance – Flow Conditioning	Revised diffuser trailing edge devices	Further refinement of the diffuser trailing edge devices, providing improved aerodynamic flow conditioning at the back of the car.

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Front Corner	Performance - Flow Conditioning	Revised Front Brake Duct design	The FBD geometry was refined to provide a smoother flow path, reducing local losses and improving downstream flow quality towards the rear of the car. The revised scoop configuration required a concurrent optimisation of the suspension leg fairings to preserve aerodynamic efficiency.
2	Cooling Louvres	Circuit specific - Cooling Range	Additional Gill option	The circuit-specific operating conditions required an additional increase in cooling capacity, achieved through the introduction of two additional apertures on the upper surface of the sidepod.

Audi Revolut F1 Team

No.	Updated component	Primary reason for update	Geometric differences	Description
1	Front Wing Endplate	Performance – Local Load	Updated front wing endplate design	The updated FWEP design leads to local load gain and improves flow structures and characteristics of the car.
2	Front Corner	Performance – Flow Conditioning	Updated lower deflector stay layout	For this event a rearrangement of the lower deflector’s stays is introduced to improve local flow conditions on the front corner.
3	Floor	Performance – Local Load	Updated rear floor design	New rear floor design resulting in a load improvement at the rear of the car, also altering rear axle load characteristic.
4	Rear Corner	Performance – Flow Conditioning	Updated lower deflector design	In combination with the rear floor update the rear deflector geometries were adapted to manage the new flow conditions in this area.
5	Rear Suspension	Performance – Local Load	Updated rear suspension design	In combination with the rear floor update the rear flow conditions in this area.
6	Beam Wing	Performance – Local Load	Updated lower beam wing design	The rear beam wing is part of the overall rear end update. This change compliments the new flow conditions around the new rear wing.
7	Rear Wing	Performance – Local Load	Updated rear wing design	The new rear wing design results in improved local load at the rear axle together with complimenting development.
