Updated sidepod top deck and engine cover louvres The sidepod top deck and engine cover louvres have been updated and refined to integrate with updates to the underlying geometry, allowing the ability to tune the cooling capacity to specific circuit requirements

Reprofiled beam wing surfaces The beam wing has been updated as part of the wider floor update, to increase load aerodynamic load at the rear of the car

Updated diffuser surface geometry The rear floor and diffuser surfaces have been updated to generate more aerodynamic load at the rear of the car whilst retaining favourable characteristics throughout the car's operating envelope

Reprofiled roll hoop leg fairing surfaces The roll hoop stays have been reprofiled to improve aerodynamic stability and therefore improve the flow conditioning to the rear of the car across a wider range of yaw angles

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.

Updated rear wing design The new rear wing design results in improved local load at the rear axle together with complimenting the updated flow conditions from floor development.

Updated rear suspension design

In combination with the rear floor update the rear suspension geometry was updated for the different flow conditions in this area.

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.

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.

Updated front wing endplate design The updated FWEP design leads to local load gain and improves flow structures and characteristics of the car.

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.

Subtle revisions to the surfaces including forward floor as well as the junction line with the topbody 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 Floor Board Performance – flow conditioning Subtle profile changes to the louvres and supports between

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.

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.

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 matching the updated floor at the junction line. Minor changes to the central engine cover and cooling louvres.

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.

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.

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.

Revised front corner geometry The front corner has been redesigned to work alongside the updated front wing, improving the flow management and aerodynamic efficiency.

New front wing design Evolution of the front wing design as part of our in- season development, delivering incremental aerodynamic gains and improving flow management.

New front wing design The nose has been updated to better integrate the new front wing design and deliver better aerodynamic performance across the front end.

Addition of a winglet An aero winglet has been added to improve local flow management and deliver efficient aerodynamic load towards the rear end.

New front wing design The front wing endplate has been part of the redesign to improve downstream flow control and enhance overall aerodynamic efficiency.

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

Removal of the central RV Tail element Free Practice test Item, not track specific and focused on data gathering and correlation exercise

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

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.

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.

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.

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.

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.

Narrower rear exit A narrower rear exit allows more cooling range tuning, biasing more cooling flow to the louvres rather than the rear exit.

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.

Revised diffuser trailing edge devices Further refinement of the diffuser trailing edge devices, providing improved aerodynamic flow conditioning at the back of the car.
