Document 8: Car Presentation Submissions - 2025 Emilia Romagna Grand Prix

Issued by the FIA Formula One Media Delegate to All Teams and Officials on 16 May 2025 at 10:58.

This document details the car presentation submissions from various teams for the 2025 Emilia Romagna Grand Prix.

McLaren Formula 1 Team

Updated componentPrimary reason for updateGeometric differences compared to previous versionBrief description on how the update works
Rear CornerPerformance - Flow ConditioningRevised Rear CornerUpdate to multiple Rear Corner and Suspension components resulting in improved flow conditioning and overall increase in rear aerodynamic load.
Rear WingCircuit specific - Drag RangeHigh Downforce Rear WingHigh Downforce Rear Wing resulting in an efficient increase in aerodynamic load with a more loaded mainplane and flap, suitable for high downforce circuits.
Beam WingCircuit specific - Drag RangeHigh Downforce Beam WingIn conjunction with the high downforce Rear Wing, a more loaded Beam Wing was developed to efficiently increase aerodynamic load.
Front SuspensionReliabilityModified Front SuspensionA small modification has been applied to the Front Suspension aiming at increased clearance to other suspension members for improved reliability.

Scuderia Ferrari HP

Updated componentPrimary reason for updateGeometric differences compared to previous versionBrief description on how the update works
Rear CornerPerformance - Local LoadRevised scoop geometry and winglet arrangementThis update is not track specific and within the standard development cycle. Geometrical changes are small, nevertheless focused on improving specific flow features, returning local loading benefits.
Rear WingCircuit specific - Drag RangeHigher downforce top and lower rear wing profilesThis rear wing cluster is carried over from last season and adds up to the pool of available downforce levels. Currently not the prime choice, but covers possible lower grip conditions.
Beam WingCircuit specific - Drag RangeHigher downforce top and lower rear wing profiles(Same description as Rear Wing)

Red Bull Racing

Updated componentPrimary reason for updateGeometric differences compared to previous versionBrief description on how the update works
Coke/Engine CoverPerformance - Local LoadRevised radiator duct inlet and sidepod shape to suitA re-optimisation of the inlet, surrounding geometry and stays to gain overall aerodynamic efficiency.
Rear SuspensionPerformance - Local LoadRevised fairing around one suspension memberSubtle change to better optimise the shape towards the inboard region for a further aerodynamic efficiency gain.
Rear CornerPerformance - Local LoadRevised wheel bodywork inlet and exit ductsMinor changes to tidy up and optimise the local flow fields to gain aerodynamic efficiency.

Mercedes-AMG PETRONAS F1 Team

Updated componentPrimary reason for updateGeometric differences compared to previous versionBrief description on how the update works
Front SuspensionPerformance - Flow ConditioningReprofiled suspension fairingsAll leg fairings reprofiled to improve aerodynamic robustness in a variety of conditions - improving flow to the rear of the car and consequently floor load.
Front WingPerformance - Flow ConditioningReprofiled front wing elements.Redistribution of chordwise and spanwise front wing load through element reprofiling, producing a change in upwash field behind the wing resulting in improved onset flow to the rear of the car.
Coke/Engine CoverCircuit specific - Cooling RangeSubtle change to engine cover shape.Upper surface geometry change improves onset flow to the rear wing, gaining local load, whilst also improving engine cooling efficiency.

Aston Martin Aramco F1 Team

Updated componentPrimary reason for updateGeometric differences compared to previous versionBrief description on how the update works
HaloPerformance - Local LoadThe local detail around the rear halo mounts has been revised with a reduced fin.Changes to the management of the flow around the cockpit alter the load generated in that area as well as affecting the flow behind this region.
Floor BodyPerformance - Local LoadThe main body of the floor has evolved slightly with the fences and floor edge.The revised shapes improve the flowfield under the floor increasing the local load generated on the lower surface and hence performance.
Floor FencesPerformance - Local LoadThe fences have revised curvature and local details.The revised shapes improve the flowfield under the floor increasing the local load generated on the lower surface and hence performance.
Floor EdgePerformance - Local LoadSmall changes to the details of the floor edge wing and the main floor inboard of this.The revised shapes improve the flowfield under the floor increasing the local load generated on the lower surface and hence performance.
DiffuserPerformance - Local LoadThe shoulder of the diffuser has been updated.The revised shapes improve the flowfield under the floor increasing the local load generated on the lower surface and hence performance.
Coke/Engine CoverPerformance - Local LoadChange to the curvature of the coke.This revised shape is developed alongside the floor edge details to improve the performance of the floor as above.
Beam WingPerformance - Drag reductionThe beam wing sections are reduced in incidence compared to the previous version.The reduction in aggression of the beam wing elements reduce downforce but also drag for an overall efficiency improvement at this rear wing level.

Updated componentPrimary reason for updateGeometric differences compared to previous versionBrief description on how the update works
Floor BodyPerformance - Local LoadThe volume within the underfloor channels has been modified, with subsequent adjustments to the fence camber and floor edge winglet positions.The channels in the forward floor create local downforce, but also define the downstream flow conditions for the rest of the floor. This update increases local load without degrading this downstream flow.
Coke/Engine CoverPerformance - Flow ConditioningThe undercut shape of the sidepod has been modified, and a chassis winglet added.The shape of the bodywork undercut has been developed to promote high energy flow towards the back of the car and the floor edge wing. The chassis winglet helps to manage the airflow reaching the rear wing.
