The 2025 IAME Euro Series drew to a close with its fourth and final round at Mariembourg, where the weather was forecast for a wet weekend but instead delivered a mix of conditions that kept teams guessing. Rain played its part early, shaking up Friday’s qualifying and the opening heats, while staying away on Saturday and making its return on Sunday with light drizzles and sudden bursts of sunshine that created ever-changing grip levels. The most dramatic twist came in the Junior final, where a shower during the formation lap sparked chaos and forced bold tyre choices. Between the shifting skies and the fierce on-track battles, Mariembourg provided a fittingly unpredictable backdrop for the season finale.
