Trident achieved a 1-2-3 classification in qualifying at Imola Circuit, with Santiago Ramos on feature race pole position ahead of teammates Leonardo Fornaroli and Sami Meguetounif.
León held the position ahead of Oliver Goethe and Tim Tramnitz through four safety car restarts.
A virtual safety car was deployed on the penultimate lap after sixth-place Browning collided with Sztuka and retired in the gravel.
Racing resumed on the final lap, and a faster reaction from Goethe allowed him to gain the lead from León and cross the finish line first.
[1] Pole-sitter Ramos held the lead at the start of the feature race, but was overtaken by Fornaroli on lap three and would ultimately drop to eighth place by the end.
