The lower beam wing can be combined with different top wing assemblies | ![Extracted image from page 5](images/car-presentation-submissions_p5_page.png) Car Presentation – Saudi Arabian Grand Prix Red Bull Racing | No. | Updated component | Primary reason for update | Geometric differences | Description | | --- | --- | --- | --- | --- | | 1 | Coke/Engine Cover | Reliability | Enlarged central exit. | Demands of circuit in Jeddah with the forecast ambient temperatures require the use of a larger topbody to reject the heat needed for cooling | | 2 | Beam Wing | Performance - Local Load | Reduced chord and camber lower or beam wing A step to reduce the downforce at a given speed to observe the lift/drag requirements for this circuit. | | ![Extracted image from page 7](images/car-presentation-submissions_p7_page.png) Car Presentation – 2025 Saudi Arabian Grand Prix *Mercedes-AMG PETRONAS F1 Team* No updates submitted for this event. Car Presentation – Saudi Arabian Grand Prix Aston Martin Aramco F1 Team | No. | Updated component | Primary reason for update | Geometric differences | Description | | --- | --- | --- | --- | --- | | 1 | Rear Wing | Circuit specific - Drag Range | Less aggressive rear wing flap to fit an existing assembly. | Part of standard development to provide a wing with less load and hence drag to suit the characteristics of this circuit. | ![Extracted image from page 10](images/car-presentation-submissions_p10_page.png) Car Presentation – Saudi Arabian Grand Prix BWT Alpine F1 Team No updates submitted for this event. Car Presentation – 2025 Saudi Arabian Grand Prix MONEYGRAM HAAS F1 TEAM | No. | Updated component | Primary reason for update | Geometric differences | Description | | --- | --- | --- | --- | --- | | 1 | Rear Wing | Circuit specific - Drag Range | Decambered Rear Wing assemblies | Two carry-over Rear Wings from VF24 will be available on track. Both with reduced drag and load level, achieved by raising and decambering the profiles. | | 2 | Front Wing | Circuit specific - Balance Range | With the lower drag levels a relaxed FW Flap profile is required. | In order to achieve a correct balance level with the introduction of above-mentioned less loaded Rear Wings a less powerful FW Flap is available as well. | ![Extracted image from page 13](images/car-presentation-submissions_p13_page.png) Car Presentation – Saudi Arabian Grand Prix Visa Cash App Racing Bulls | No. | Updated component | Primary reason for update | Geometric differences | Description | | --- | --- | --- | --- | --- | | 1 | Front Wing | Circuit specific - Balance Range | The chord length of the front wing flap has been reduced. | Shortening the chord of the flap results in less load being generated by the front wing at a given flap angle, allowing the car to be balanced for the lower rear wing levels expected at this circuit. | | 2 | Rear Wing | Circuit specific - Drag Range | Reduced camber & incidence wing elements. | An efficient reduction in drag & downforce is achieved by de-cambering the upper wing and raising the leading edge, making it a good option for this circuit to achieve the optimum lap time. | | 3 | Beam Wing | Circuit specific - Drag Range | Reduced chord & incidence lower element. | Further efficient drag reduction is achieved by reducing the load generated by the lower element of the beam wing. | ![Extracted image from page 15](images/car-presentation-submissions_p15_page.png) Car Presentation – Saudia Arabia Grand Prix *Atlassian Williams Racing* No updates submitted for this event. Car Presentation – Saudi Arabian Grand Prix Stake F1 Team KICK Sauber | No. | Updated component | Primary reason for update | Geometric differences | Description | | --- | --- | --- | --- | --- | | 1 | Front Wing | Circuit specific - Balance Range | Low balance front wing flap design | The smaller front wing flap reduces the load generated by the front wing to ensure that we can rebalance the low-drag rear wing introduced for this circuit. | | 2 | Floor Body | Performance - Local Load | Changes to central floor geometry | This change is aiming to improve flow characteristics around the rear floor, for efficient downforce gain. | | 3 | Beam Wing | Circuit specific - Drag Range | Newly designed beam wing and rear wing endplate. | Combined change of beam wing and rear wing endplate geometry to increase overall efficiency at lower downforce levels. | | 4 | Rear Wing Endplate | Circuit specific - Drag Range | Newly designed beam wing and rear wing endplate. | Combined change of beam wing and rear wing endplate geometry to increase overall efficiency at lower downforce levels. | | 5 | Rear Wing | Circuit specific - Drag Range | Low drag rear wing assembly | efficiently. We can combine the main plane with several flaps to tune load and drag. | ![Extracted image from page 18](images/car-presentation-submissions_p18_page.png)
