MONTEREY, Calif. (May 11, 2025) – Porsche kicked off its sponsorship as the official vehicle of WeatherTech Raceway Laguna Seca in grand fashion on Sunday, claiming the top two spots in the IMSA TireRack.com Monterey SportsCar Championship main event.

The theme of streaks – both in the 2025 IMSA WeatherTech SportsCar Championship season and at WeatherTech Raceway Laguna Seca – continued, as each of last year’s winning cars, the No. 6 Porsche Penske Motorsport Porsche 963, No. 77 AO Racing Porsche 911 GT3 R and No. 57 Winward Racing Mercedes-AMG GT3, claimed victories for the second consecutive year in the two-hour, 40-minute race.

The Porsche Penske Motorsport team won its fourth straight Grand Touring Prototype (GTP) race of the season. But for the first time, it was Mathieu Jaminet and Matt Campbell in the No. 6 Porsche 963 who broke through for their first win of the season instead of teammates Nick Tandy and Felipe Nasr in the No. 7 car. Jaminet scythed through GT traffic just ahead of Tandy and emerged victorious by 1.692 seconds.

The drama came down to the 124th and final lap, where Jaminet made one final move past a GT car at Turn 10, which provided enough of a buffer for Tandy to lose momentum. That opened the door for pole sitter Dries Vanthoor in the No. 24 BMW M Team RLL BMW M Hybrid V8 to attempt a pass on the outside, but contact between the two sent Vanthoor off the track. Vanthoor limped back across the line in third place. IMSA race officials reviewed the incident and took no further action.

AO Racing won its third straight race across the WeatherTech Championship’s two GT classes with the No. 77 AO Racing Porsche 911 GT3 R driven by Grand Touring Daytona Pro (GTD PRO) full-season drivers Laurin Heinrich and Klaus Bachler. The win comes a year after AO Racing won its first GTD PRO race at Monterey last year. The pole sitting No. 81 DragonSpeed Ferrari 296 GT3 finished second ahead of the No. 3 Corvette Racing by Pratt Miller Motorsports Corvette Z06 GT3.R.

In Grand Touring Daytona (GTD), the same combatants who raced for the win at the Mobil 1 Twelve Hours of Sebring – Philip Ellis in the No. 57 Winward Racing Mercedes-AMG and Jack Hawksworth in the No. 12 Vasser Sullivan Racing Lexus RC F GT3 – did so again in this race. The same result occurred as Ellis and Russell Ward secured the win ahead of Hawksworth and Parker Thompson. Conquest Racing completed the podium in class with its No. 34 Ferrari 296 GT3.

In addition to Sunday’s IMSA main event, the weekend hosted five additional support series races. Arriving as the points leaders in the Grand Sport (GS) class, RS1’s Jan Heylen and Luca Mars (No. 28 Porsche 718 GT4 RS CS) brought home the overall victory in Saturday’s IMSA Michelin Pilot Challenge race, while the team at Bryan Herta Autosport with Curb Agajanian saw its trio of Hyundai Elantra N TCR cars grab a 1-2-3 finish in the TCR class. Nick Persing of Wayne Taylor Racing led the charge of Italian bulls all weekend, claiming back-to-back wins in Lamborghini Super Trofeo North America. Rounding things out in Mustang Challenge was Robert Noaker, who capped off the race weekend by claiming back-to-back victories for races one and two.
