Porsche’s ability to maintain competitiveness across different circuits helped offset limited race victories and secure the overall titles through steady execution.

The drivers’ championship went to Matt Campbell from Australia and Mathieu Jaminet from France in the No. 6 Porsche 963. Their season-long consistency proved decisive, even after teammate Julien Andlauer was ruled out of the finale for medical reasons. Laurens Vanthoor stepped in to complete stints in both cars, helping the team maintain focus through the closing hours.

Porsche also defended its IMSA Michelin Endurance Cup title, which measures performances across the season’s longest races. The hybrid-powered Porsche 963 remained competitive throughout, with the No. 6 car leading multiple phases and Felipe Nasr in the No. 7 pushing into the front group early.
