FIA document · Car Presentation Submissions, Dutch Grand Prix

Zandvoort: six teams update their cars without circuit-specific packages

Six teams file 23 technical updates on the eve of the Dutch Grand Prix. The analysis of the official FIA document shows how development remains concentrated on the floor and on overall efficiency, postponing maximum-downforce wings to later races.

The official document The FIA documentation and the classification of components

Zandvoort's unique characteristics, between banked corners and continuous changes of gradient, require a high level of downforce to stabilise the car. The official FIA document on car presentation submissions reveals the teams' development approach for the resumption of the championship.

Out of eleven teams, six have introduced technical evolutions for a total of 23 declared components. Of these, 0 of 23 belong to the circuit-specific adaptation category: every team has focused its efforts on pure performance development packages destined to remain on the car for the rest of the season.

Each team has a row with its name — the bar on the right is the parts declared as development («Performance») — and, where there are any, a second row «· circuit» on the left with the configuration ones («Circuit specific»); the order is that of the development bar. These are rows of the document: a shared description can cover more than one. The note on the right says in how many previous 2026 weekends that team had brought updates (excluding this one).Who brings what to Zandvoort: parts declared to the FIA, by teamNetherlands 2026 · FIA document◄ CONFIGURATION (Circuit specific)DEVELOPMENT (Performance) ►Alpine+8Aston Martin+5Ferrari+5McLaren+3Mercedes+1Audi=no updates declaredCadillac=no updates declaredHaas=no updates declaredRacing Bulls=no updates declaredRed Bull=Williams=no updates declaredrows of the document, not size or number of updates · outside the figure: 1 reliability

Development and efficiency Floors and flow management at the centre of the technical updates

The 23 registered components correspond to 19 distinct design interventions. Ferrari introduces five modifications concentrated on the interaction between the floor edge, the diffuser and the side fences, while Aston Martin adopts a new front flap aimed at widening the balance window between front and rear axle.

Alpine brings the biggest package to the track with 8 development items, aimed at optimising the flow towards the rear end. Of 23 entries, 22 are declared with the primary aim of increasing local downforce, while just one modification concerns the reliability of the braking system.

On-track impact The correlation between wind tunnel and lap-time evidence

The distribution of the modifications favours the central body of the car: the floor collects 7 interventions, followed by diffuser, wings and brake ducts with three each. The common goal remains the stability of the aerodynamic platform as ride heights vary.

The real effectiveness of each update will be verified during the long runs in free practice, where sensors and minimum-speed telemetry will make it possible to quantify the actual gain in terms of stability and tyre thermal performance.
