Porsche Penske Motorsport will again field two Porsche 963 prototypes in the GTP class—the top category of IMSA’s WeatherTech Championship.
The 963 is a hybrid prototype built to the LMDh ruleset, and Porsche’s 2025 season wrap-up notes how dominant the platform has been in IMSA since the rules debuted.
Here’s the part that catches a lot of fans off guard: while the FIA WEC still has a published 2026 calendar, multiple reports confirm Porsche’s factory Porsche Penske Hypercar effort withdraws from WEC for 2026, meaning the team won’t be contesting those rounds for overall wins next year.
Porsche’s own Night of Champions communications emphasize a revised focus that keeps the factory 963 push centered on IMSA.
Porsche and IMSA both outline the 2026 plan clearly:
For the endurance classics, Porsche adds firepower:
And if you’re tracking the offseason dominoes: IMSA notes Mathieu Jaminet departs Porsche for Genesis in 2026, which is a major storyline given his recent championship role.
IMSA’s official 2026 WeatherTech schedule lays it out cleanly. Here’s the calendar you can pin to the fridge.

Why this schedule matters for Porsche Penske: it mixes sprint rounds (like Long Beach and Detroit) with endurance pillars (Daytona, Sebring, Watkins Glen, Road America, Petit Le Mans). For a team built on pit-stop precision and long-run pace, these are exactly the kinds of weekends where championships are won.
Porsche’s 2025 IMSA story wasn’t “a couple of good weekends.” It was a season where Porsche says it secured six championship crowns, including a repeat of the biggest prizes at the top of the sport.
IMSA’s team listing for the No. 7 Porsche Penske entry captures the punchline: in 2025 the team won the Rolex 24 at Daytona, Sebring, and Long Beach in GTP.
That’s not just “successful.” That’s the kind of start that changes how the paddock views you for the rest of the year.
Team Penske’s 2025 IMSA season review describes how the No. 6 program stacked results when it mattered—specifically noting a podium at Detroit and a third at Petit Le Mans, the kind of finishes that turn a tight points chase into a championship celebration.
Porsche’s own recap of the Road Atlanta finale also notes the factory 963s finishing third and tenth, enough to secure the manufacturers title again and cap off that multi-title season.
Put simply: Porsche Penske didn’t just win races—they proved they could win different kinds of races:
That’s the blueprint for a repeat.
In IMSA, Porsche Penske is the factory spearhead in GTP, the headline prototype class.
WEC still matters to Porsche fans—especially with the Le Mans gravitational pull—but for 2026, the key point is that Porsche Penske won’t be the factory Hypercar presence there.
So if your goal is to follow Team Porsche Penske specifically, the “must-watch” list is IMSA-first in 2026.
New driver pairings, the same factory intensity, and a schedule packed with endurance races where execution beats hype every single time.
