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.

With Porsche back on top, AO Racing’s California magic intact, and Mercedes-AMG doubling down in GTD, Laguna Seca once again delivered a masterclass in green-flag strategy and edge-of-your-seat finishes.

Dries Vanthoor and BMW M Team RLL are still perfect in IMSA WeatherTech SportsCar Championship qualifying in 2025.For the fourth straight race, the No. 24 BMW M Hybrid V8 of Vanthoor and Philipp Eng will start on pole position,
