Each race weekend in the Iberian Peninsula's popular GT4, TCR, and one-make series features two 15-minute qualifying sessions and two 50-minute races with a mandatory pit stop, offering drivers and teams ample track time across practice, qualifying, and races.
The combined calendar of the three series includes six events, held at iconic circuits across Spain and Portugal such as Circuito de Madrid Jarama, Circuito de Jerez, Circuit Ricardo Tormo in Cheste, Autódromo Internacional do Algarve, Circuito do Estoril, and the ultimate challenge — the Vila Real Street Circuit.
The FIA driver categorisation system for GT classes, along with a single tyre supplier provided by Pirelli, are key elements behind the success of this racing format.
