The Hungaroring has remained active after the Hungarian Grand Prix, with Alpine, Audi and Aston Martin taking part in a Pirelli tyre test focused on the development of compounds planned for the 2027 Formula 1 season.
While much of the paddock has moved into the summer break, Franco Colapinto and Gabriel Bortoleto stayed on circuit for Alpine and Audi respectively. Aston Martin also ran its third driver, Jak Crawford, on Tuesday before using Honda’s new-specification power unit during a filming day on Wednesday.


The programme provided Pirelli and the teams with a broad comparison of tyre behaviour. The three drivers began with screening runs across various C3 options, establishing an initial performance picture before moving into longer stints. Those long runs were used to assess the performance and degradation characteristics of the most promising variants.

The work also extended beyond the C3 specification. Colapinto and Bortoleto evaluated several C4 and C5 compound variants through qualifying simulations and higher-mileage running, adding both short-run performance data and information from more sustained stints. The testing therefore combined outright pace assessment with the degradation analysis required to identify the strongest candidates for further development.
The programme fits into Pirelli’s wider effort to define its future tyre range; the company’s recent compound selections for Zandvoort, Monza and Madrid underline the importance of matching tyre behaviour to the demands of each circuit.

Bortoleto completed the most laps on Tuesday, recording 141 tours of the Hungaroring. His best time of 1m 20.813s, however, was surpassed by Colapinto, who set the day’s quickest lap with a 1m 20.371s effort after completing 128 laps.
Crawford logged 136 laps and recorded a fastest time of 1m 24.598s. The differing mileage totals reflect the test’s emphasis on data collection rather than a conventional competitive classification, with the drivers completing varied tyre and run programmes.
Testing continues on the following day for Colapinto and Bortoleto, who are scheduled to repeat a programme similar to Tuesday’s running as Pirelli continues its evaluation of the 2027 compounds.
