Dutch GP – All official updates: upgrades only for 3 teams
The FIA has published the technical and summary documents detailing all the updates brought by the teams to the Netherlands for the fifteenth round of the Formula 1 season.
On Friday in Zandvoort, two targeted interventions on the cars stood out. Red Bull introduced an evolution to the front wing, with longer chord flaps to increase local load in the medium-speed corners of the Dutch circuit. Sauber focused on the rear corner, updating the design of the rear brake duct winglets to optimize flow conditioning and improve diffuser efficiency. Two different approaches, both aimed at exploiting Zandvoort’s technical characteristics. Alpine also introduced a rear corner upgrade at the Dutch GP, focusing on the rear brake ducts.
No major update packages were expected at this stage of the season: the calendar and the proximity to the summer break push teams to save the most significant developments for tracks like Monza, where the update season traditionally concludes.
Here are all the changes made to the new cars:

Red Bull
The update concerns the Front Wing: the flaps have a longer chord to generate more local load at the front. On a track like Zandvoort, where entry grip is crucial, the increased surface area allows better use of the attack angle and provides more front downforce without changing the overall wing philosophy. In short: more usable area = more downforce in medium-speed corners, with potential benefits in balance and front tire degradation protection.
| Component | Reason | Differences | Description |
|---|---|---|---|
| Front Wing | Performance – Local Load | Longer chord front wing flaps | Zandvoort’s requirements call for extended chord flaps to increase available load by acting on the attack angle. |

Alpine introduced a rear corner upgrade at the Dutch GP, focusing on the rear brake ducts. The modification involves the “furniture” with redesigned winglets to optimize flow conditioning and reduce turbulence caused by the rear wheel. The goal is to improve wake quality and, consequently, overall rear efficiency.
| Component | Reason | Differences | Description |
|---|---|---|---|
| Rear corner | Performance – Flow Conditioning | Redesigned rear brake duct “furniture” | Upgrade to the rear brake duct “furniture,” with a set of reshaped winglets designed to improve wake management generated by the rear wheel. |

The update concerns the rear corner, with a new design for the rear brake duct winglets. This modification aims to improve flow conditioning, i.e., the management of aerodynamic flow at the rear of the car. A cleaner and more controlled flow helps improve diffuser efficiency and reduce interference from the rear wheels, benefiting stability and overall rear downforce.
| Component | Reason | Differences | Description |
|---|---|---|---|
| Rear Corner | Performance – Flow Conditioning | Updated rear brake duct winglet design | The changes to the rear brake duct winglets affect the airflow around the rear of the car, particularly toward the diffuser and rear wheels. |
