Porsche Penske Motorsport remained unbeaten in the 2025 IMSA WeatherTech SportsCar championship season but with a twist at Laguna Seca Raceway. The No. 6 Porsche 963 earned its first Grand Touring Prototype victory this year as Mathieu Jaminet and Matt Campbell beat teammates Felipe Nasr and Nick Tandy in the No.

In a year where a single team's dominance has been the story across IMSA and the FIA WEC's respective top categories, Porsche Penske Motorsport finishing 1-2 at Laguna Seca is hardly a surprise.

The victory by Jaminet and Campbell, better known as “The Matts,” was the team’s 43rd IMSA win and 24th IMSA 1-2 finish.
