Preview, IMSA WeatherTech SportsCar Championship, Round 4, Laguna Seca (USA)

Atlanta. Porsche tops the leaderboard in all IMSA 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 California 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. Last year, the No. 6 Porsche triumphed on the hilly, 2.258-mile circuit on the Monterey Peninsula. 

“We’ve enjoyed an incredibly good run in this year’s IMSA series. We want to continue like this,” Thomas Laudenbach, Vice President Porsche Motorsport, said. “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,” Urs Kuratle, Director Factory Motorsport LMDh, said. “Our race car is the most successful hybrid prototype since the introduction of the LMDh regulations. We want to defend this position and further extend our lead in all championship standings. Tire strategy, driver skill, 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,” Jonathan Diuguid, Managing Director Porsche Penske Motorsport, said. “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 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 to continue their full season run. JDC-Miller MotorSport is currently ninth in the team championship standings.

“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 WeatherTech Raceway 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 565 PS (416 kW) Porsche 911 GT3 R. Team owner Adam Adelson and fellow American Elliott Skeer will compete in the No. 120 car. The pair of drivers with California roots aim to repeat last year’s podium result in the class.

The race

The 2.258-mile WeatherTech Raceway Laguna Seca features 11 turns, including the famous “Corkscrew.” 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 miles from the Monterey Bay and Pacific Ocean. 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 tire wear contributing to race strategy options.

Official Sponsorship Between Porsche and Laguna Seca

Earlier this week, Porsche Cars North America announced it will become the “Official Car of WeatherTech Raceway Laguna Seca.” As part of the sponsorship, Porsche will support Friends of Laguna Seca in its commitment to revitalize the Raceway and Recreation Area.

A Porsche Driving Center (PDC) will also launch at the legendary raceway in 2026.

Customers will be able to choose from introductory courses, which start with the basics of vehicle control, through intermediate and advanced training for those seeking to sharpen existing skills.

The sponsorship launches with Porsche as the official pace car for this weekend's race.

Drivers’ comments before the race:

Mathieu Jaminet (Porsche 963 #6): “I’ve celebrated several triumphs 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.”

Gianmaria Bruni (Porsche 963 #85): “I’m really looking forward to returning to Laguna Seca. The course is very special and one of the most iconic venues on the IMSA racing calendar. I can’t wait to race there again. We’ve seen in previous years that the Porsche 963 is very competitive on the Californian racetrack. Now, as a team, we want to tap the full potential and turn it into a good result.”

Klaus Bachler (Porsche 911 GT3 R #77): “Laguna Seca has a fantastic track layout set in a stunning landscape – making it one of the most beautiful races on the calendar. I secured my first pole position in the IMSA series there in 2023. AO Racing also achieved its first class victory there last year with ‘Rexy.’ Now our green 911 is taking a short break, and we’re bringing out its pink sister, ‘Roxy’. We feel well-prepared and highly motivated. We currently rank second in the championship and we’re eager to forge ahead.”

Adam Adelson (Porsche 911 GT3 R #120): “Laguna Seca is one of the most storied tracks on the calendar. Everyone senses this as soon as they enter the facility. Our first races of the season were great. We want to build on our experience and the lessons learned and achieve a top result. Last year, we finished on the podium at Laguna Seca. Our team will put a fast Porsche 911 GT3 R on the track for us. Elliott and I will then have everything we need to get back into the top three.”
