The FIA has released the technical documents detailing all the updates teams have brought to the Austrian Grand Prix, the eleventh round of the 2025 Formula 1 season.
Several teams introduced significant changes at the Red Bull Ring, with a clear focus on the floor area—specifically the floor body, floor edge, and diffuser. These updates aim to improve flow conditioning and optimize aerodynamic load distribution, reflecting the ongoing quest to balance downforce and drag.
Another common theme is adaptation to the specific demands of the Red Bull Ring. Mercedes, for example, adjusted its cooling openings to manage the high braking and thermal loads of the circuit. Similarly, Racing Bulls and Sauber introduced new wing configurations tailored to specific efficiency or downforce ranges.
These, along with upcoming developments for Silverstone, may represent the final major structural updates of the season, as teams now face reduced development margins and must begin reallocating budgets and resources for the 2026 regulation changes.
Here is a summary of the updates introduced by each team.
McLaren
McLaren continued its technical evolution with three targeted updates for the Austrian GP. The most significant change is a redesigned front suspension geometry to enhance flow conditioning and overall aerodynamic efficiency. Supporting this, front corner aero devices have been revised to complement the new suspension setup. At the rear, an alternative suspension geometry has been introduced, prompting changes to the aerodynamic surfaces around the rear corners to maintain performance and functionality. This cohesive package shows McLaren’s focus on refining both mechanical systems and airflow management.
Ferrari
Ferrari debuted a new floor package at the Red Bull Ring, part of a broader development plan beyond just this event. Updates involved a coordinated revision of the fences, floor body, outer edge, and diffuser. The floor fences were redesigned to better manage vortex generation toward the rear. The central floor section features a new “boat-shaped” contour with expanded tunnels. The floor edge has been shortened and curved, and the diffuser received a volumetric redesign. All components were re-optimized to improve load distribution across the car, boosting aerodynamic performance throughout its full operating window.
| Component | Reason | Differences | Description |
|---|---|---|---|
| Floor Fences | Performance – Flow Conditioning | Redistribution of fences profiles / camber | Not event specific, this floor package features updated front floor fences targeting an enhanced vorticity released downstream. The reshaped boat and tunnel expansion have been subsequently reoptimized, together with the floor edge loading and diffuser volume distribution, leading to an overall load gain across the car operating envelope. |
| Floor Body | Performance – Flow Conditioning | Reshaped boat and tunnel expansion | |
| Floor Edge | Performance – Flow Conditioning | Shorter and re-cambered front floor edge wing | |
| Diffuser | Performance – Flow Conditioning | Redesigned diffuser volume |
Red Bull
Red Bull introduced a targeted update to the floor edge for the Austrian GP, specifically in front of the rear wheels. The new surface features an outlet designed to maintain established flow stability in that region while enhancing local load generation. This aerodynamic refinement targets a key area of the floor to maximize overall car efficiency.
| Component | Reason | Differences | Description |
|---|---|---|---|
| Floor Edge | Performance – Local Load | New surfaces with a vent ahead of the rear tyre | A new edge wing is being deployed intended to maintain the established flow stability and improve the load extracted from this region of the floor. |
Mercedes
Mercedes focused its updates exclusively on addressing the climatic and technical demands of the Red Bull Ring, one of the most thermally demanding tracks on the calendar. Brake ducts were enlarged both at the inlet and outlet to handle the heavy braking loads. Additionally, the rear bodywork was modified with a larger exit to allow greater airflow through the side radiators, improving cooling efficiency. This is a circuit-specific package aimed at managing temperatures under high stress.
| Component | Reason | Differences | Description |
|---|---|---|---|
| Front Corner | Circuit Specific – Cooling Range | Large brake duct inlet and exit | Increased front brake duct inlet and exit area to cover off the high brake duty that we typically see at this circuit. |
| Coke/Engine Cover | Circuit Specific – Cooling Range | Large rear bodywork exit | Increased bodywork exit area designed to increase mass flow through the sidepod radiator and hence provide the additional cooling required for this circuit. |

Visa Cash App Racing Bulls
The Racing Bulls team introduced two aerodynamic updates for Austria. The front wing features redesigned flaps to improve local flow conditioning and deliver better aero performance across various conditions. The rear wing has also been updated with a revised profile to balance downforce and drag according to the Red Bull Ring’s characteristics. Overall, it’s a well-rounded package focused on lap-time efficiency.
| Component | Reason | Differences | Description |
|---|---|---|---|
| Front Wing | Performance – Flow Conditioning | New front wing flap geometry | The flap has been changed to improve local flow conditioning and help increase aerodynamic performance across a range of conditions. |
| Rear Wing | Circuit specific – Drag Range | Updated rear wing profiles | The upper rear wing has been changed to meet the needs of the target downforce & efficiency level for the circuit. |

Stake F1 Team KICK Sauber
Sauber brought two updates to enhance aerodynamic load distribution in specific areas of the car. Changes to the central floor section include modifications in the mid-floor and outer floor edge, along with a diffuser revision aimed at optimizing airflow from front to rear. A new high-downforce rear wing was also introduced. Its reprofiled geometry enables more efficient downforce generation, with benefits expected across multiple high-load circuits through the rest of the season.
| Component | Reason | Differences | Description |
|---|---|---|---|
| Floor Body | Performance – Local Load | Changes to mid floor area incl. outboard floor edge and diffuser | Modifications are targeted at improved flow field conditions for the underfloor from front to back, gaining some efficient downforce. |
| Rear Wing | Performance – Local Load | New rear wing assembly | New rear wing assembly suited for higher downforce tracks. Overall reshaped geometry with a more efficient load distribution. Covers a variety of tracks until the end of the season. |
