The Laguna Seca Raceway in California hosts round four of the IMSA WeatherTech SportsCar Championship this coming Sunday (11 May). The factory team will campaign a pair of 485 kW (659 PS) Porsche 963 racers in the top GTP category, with the customer team JDC-Miller MotorSports fielding an additional hybrid prototype from Weissach. Two Porsche 911 GT3 R cars will contest both GT classes at the season's first IMSA event featuring a 2-hour and 40-minute race. On the same weekend, Porsche Penske Motorsport will tackle the FIA World Endurance Championship (WEC) at Spa-Francorchamps, Belgium.
Stuttgart. Porsche tops the leaderboard in all championship standings thanks to victories at the 24 Hours of Daytona, the 12 Hours of Sebring, and most recently the sprint race on the streets of Long Beach. The factory team has prepared for the upcoming IMSA round at Laguna Seca with test drives on the famed Californian racetrack. Felipe Nasr and Nick Tandy will share the wheel of the No. 7 Porsche 963. The duo from Brazil and Great Britain dominated the first three races of the year. In the sister car, Australian Matt Campbell and Mathieu Jaminet from France hope to score their first win of the season. In 2024, the No. 6 Porsche triumphed on the hilly, 3.601-kilometre circuit near the port city of Monterey.
"We've enjoyed an incredibly good run in this year's IMSA series. We want to continue like this," explains Thomas Laudenbach, Vice President Porsche Motorsport. "The motivation within our team is at an absolute high. We've won on three completely different courses over very different distances - such achievements build confidence. I'm confident our chances look good again next weekend. We want to make the most of those opportunities to repeat last year's Laguna Seca victory."
"We finished second in our 2023 debut year at Laguna Seca, last season we came first and third - the circuit and the Porsche 963 are obviously well suited," states Urs Kuratle. "Our race car is the most successful LMDh hybrid prototype since the introduction of the regulations. We want to defend this position and further extend our lead in all championship standings," emphasises the Director Factory Motorsport LMDh. "Tyre strategy, driver skills, and the team's pit stop performance play a decisive role on this rollercoaster circuit in California. We've been on top of our game in all three disciplines recently. That gives me confidence."
"Our team was able to finish on the top step of the podium in the 2024 edition of the Laguna Seca race and we have the same goals for this year," states Jonathan Diuguid, Managing Director Porsche Penske Motorsport. "Execution has been a big part of our results so far in the 2025 IMSA season and the team is on a roll. We can't wait to get our pair of 963 back on track and continue to keep the pressure on our competitors."
In the top GTP class, another hybrid prototype from Weissach will compete alongside the two Porsche 963 racing cars from Porsche Penske Motorsport. The JDC-Miller MotorSports customer squad entrusts the No. 85 vehicle to Gianmaria Bruni from Italy and Tijmen van der Helm from the Netherlands.
"Rexy" Porsche 911 GT3 R takes a break, identical twin "Roxy" steps in
In the GTD Pro class, fans will miss their beloved "Rexy" at Laguna Seca. The green Porsche 911 GT3 R decked out in its distinctive dinosaur livery will remain in the garage after its Sebring victory and recent success in the GTD class at Long Beach. Luckily, AO Racing has a replacement: for the first time this season, the pink 911, dubbed "Roxy", will line up on the grid to contest round four. Two former Porsche Juniors will share the cockpit: Austrian Klaus Bachler and reigning IMSA champion Laurin Heinrich from Germany.
In the GTD category, in which professionals and amateurs share a car, the Wright Motorsports customer team will field an identical ca. 416 kW (565 PS) Porsche 911 GT3 R. Team owner Adam Adelson and fellow American Elliott Skeer will compete in the No. 120 car. The duo aims to repeat last year's podium result.
The race
The 3.6-kilometre Laguna Seca Raceway features 11 turns, including the famous "corkscrew" passage. The narrow steeply banked left-right combination is often the scene for spectacular overtaking moves. The "corkscrew" section of the racetrack is so unique that Porsche replicated it on its own racetrack in Leipzig.
The tradition-steeped American circuit lies on a plateau just a few kilometres from the Pacific port city of Monterey. The surface of the racetrack built in 1957 now offers plenty of grip thanks to last year's resurfacing. Persistent winds blow sand onto the track, which results in higher tyre wear.
Drivers' comments before the race
Mathieu Jaminet (Porsche 963 #6): "I've celebrated several good results at Laguna Seca, and I particularly enjoyed our overall victory last year. That's why I'm excited to return there this year. The season started well for our team, but not quite as well for our No. 6 car: Victory has been just out of reach. We now want to be at the top of the podium. That's our major goal for the coming weekend."
Felipe Nasr (Porsche 963 #7): "Laguna Seca with its unique surroundings is a wonderful venue for motor racing. Fans unfailingly create a fantastic atmosphere. We're currently riding a wave of success. I'm so proud of our team. Their unwavering commitment and determination make me excited and confident about this coming weekend. We'll give it our best shot at Laguna Seca and try to extend our championship lead even more."
