Team Updates Summary

1. McLaren Mastercard F1 Team

Updated Component	Primary Reason	Geometric Differences	Description
Rear Wing	Performance - Drag reduction	Alternative Straight Line Mode Flap Position and Beamwing	The high isochronal rear wing has been modified to deploy the flap to an alternative position in straight line mode in combination with a less loaded beam wing, resulting in a larger reduction in drag.
Floor Furniture	Performance - Flow Conditioning	Updated Floor Furniture	A small modification to the floor furniture, resulting in better flow conditioning and resultant improvement of aerodynamic performance of the floor as well as drag reduction.

2. Mercedes-AMG PETRONAS F1 Team

Updated Component	Primary Reason	Geometric Differences	Description
Rear Wing	Circuit specific - Drag Range	Various winglet devices removed from rear wing.	Removing the rear wing winglets reduces assembly camber shedding local downforce and drag at a ratio appropriate for Monza L/D.
Front Bodywork	Circuit specific - Drag Range	Mirror rear stays trimmed.	The mirror stay trim reduces local camber and loading, shedding local downforce and drag at a ratio appropriate for Monza L/D.

3. Oracle Red Bull Racing

Updated Component	Primary Reason	Geometric Differences	Description
Rear Corner	Reliability	Rear suspension to wheel bodywork gaitor revision	To improve reliability of the rear wheel bodywork assembly, the gaitor providing an aerodynamic seal has been changed to reduce the probability of splitting from the wishbone and now removed winglet junctions
Floor Body	Performance – Local Load	Revised bib edge profile	In seeking to validate an alternative geometry, the edge profile has been revised for evaluation in Monza. The new geometry will revise the flow to create more local load with improved aerodynamic stability.
Exhaust Tailpipe	Reliability	Revised tailpipe bracket	In order to operate the Power Unit reliably around the Monza circuit with its unique demands, the tailpipe bracket has been trimmed to offer less blockage.
Front Wing	Flow Conditioning	Revised endplate vane	A trimmed front wing end plate dive-plane is available for evaluation in Monza which aims to improve downstream load from the floor.

4. Scuderia Ferrari HP

Updated Component	Primary Reason	Geometric Differences	Description
Floor Board	Circuit specific - Drag Range	Front floor board elements optimisation, single vertical element	Seen as a package, the primary aim of these modifications has been to adapt to Monza circuit peculiar characteristics and car aerodynamic efficiency requirements. All the steps have been targeting aerodynamic drag saving, coming along with downforce reduction as a natural consequence, but in a favourable ratio for this track.
Mirror Stay	Circuit specific - Drag Range	Shorter mirror vertical stay and connection to sidepod	(See package description above)
Rear Corner	Circuit specific - Drag Range	Removal of rear brake duct winglet cascade	(See package description above)
RV Tail	Circuit specific - Drag Range	Slotted central winglet element, trimmed side winglets	(See package description above)

5. Williams

Updated Component	Primary Reason	Geometric Differences	Description
Halo	Circuit specific - Drag Range	A vertical fence has been introduced around the Halo geometry.	We have modified the local pressure distribution around the driver cockpit area. This results in a downstream flow field change which benefits efficiency levels specific to the Monza circuit.
Front Wing	Circuit specific - Balance Range	A reduction in chord of the FWF elements.	The rearward element on the FW assembly has been modified to suit the balance requirement of the Monza circuit.
Floor Body	Circuit specific - Drag Range	A local trim has been applied to the Floor Board geometry.	This is a further circuit specific change, altering the balance between downforce and drag at the front of the main floor.

6. Visa Cash App Racing Bulls

Updated Component	Primary Reason	Geometric Differences	Description
Rear Wing	Circuit Specific – Drag Range	New assembly with updated SM mechanism.	The rear wing changes facilitate increased flap travel in Straight Mode. This allows an efficient drag reduction which suits the nature of the circuit.
Exhaust Tailpipe	Performance – Flow Conditioning	Repositioned tailpipe with reprofiled bracket	The tailpipe updates improve the flow management around the centreline of the car, allowing the floor and rear wing to perform more efficiently.

7. Aston Martin Aramco F1 Team

Updated Component	Primary Reason	Geometric Differences	Description
Front Suspension	Performance - Local Load	Revised fairings for one of the front suspension members.	The external fairing for one of the front suspension members has been modified to improve alignment with the onset flow.
Floor Edge	Performance - Local Load	Update to the area of the floor in front of the rear tyre.	The geometry in front of the rear tyre has been modified to improve the airflow to the underside of the floor increasing load generated in this area.

8. TGR HAAS F1 TEAM

Updated Component	Primary Reason	Geometric Differences	Description
Floor	Performance - Local Load	New Front Floor - new side geometry and diffuser update	The floor update focuses on optimising the main expansion region and associated side geometry to improve airflow behaviour throughout the floor. The revised design increases floor efficiency, delivering a net gain in overall aerodynamic performance and downforce production.
Bodywork	Performance - Local Load	New Sidepod and coke-line. Narrower Roll-Hoop and updated engine cover	The revised bodywork has been developed in conjunction with the new floor design to maximise the aerodynamic benefit of the floor package. The updated geometry improves airflow management around the car while providing the necessary cooling performance for all operating conditions.
Rear Corner	Performance - Local Load	Realigned rear suspension fairings and drum deflectors	The aerodynamic changes introduced by the new floor and bodywork package alter the flow structures reaching the rear corner region. To accommodate these changes and maximise the benefit of the update, the rear corner fairings have been re-optimised and the rear drum deflectors realigned, improving local flow management and overall aerodynamic efficiency.

9. Audi Revolut F1 Team

No updates submitted for this event.

10. BWT Alpine F1 Team

Updated Component	Primary Reason	Geometric Differences	Description
Front Wing Endplate	Performance - Local Load	Revised footplate vane	As part of our front wing development program, the vane has been redesigned to increase the local load and improve local flowfield.
Rear wing	Performance - Drag Reduction	SM pod fairing removal	The SM pod on the launch rear wing has been adjusted to better suit the low drag nature of the Monza track.

11. Cadillac

Updated Component	Primary Reason	Geometric Differences	Description
Forward Floor Board Stay	Performance – Flow Conditioning	Updated stay position with higher outboard attachment point	Revised forward floor board stay geometry which improves flow conditioning to the rear of the car, increases structural stability of the component and improves overall aerodynamic load at the rear of the car
Diffuser Vane	Performance – Local Load	Addition of vane to inner trailing edge of outboard diffuser sidewall	A small vertical turning vane has been added to the inner trailing edge of the outboard diffuser sidewall, which improves aerodynamic performance in the outer floor channels and increases the load at the rear of the car
