If you've ever fantasized about racing a 911. Porsche is giving you something to geek out about. The company is developing a new 911 GT3 Cup car that will be based on the 992.2 GT3 roadgoing model. It's supposed to make a bit of noise in the motorsport scene, especially in the U.S. This is more than a cosmetic overhaul-it's a complete performance refresh that was designed for track use. And it's coming in 2026.

Whether you are an extreme Porsche fan or just a fan of race car stuff, here's all of the info you'll need - broken down into simple terms.

It's Based on the New GT3, But Made for Racing

Even though the new Cup car looks a lot like the revamped 992.2 GT3 you see on the road, don't be mistaken—this thing is all business beneath the skin.

  • 100 percent track-only, it has no creature comforts and is purpose-built for on-the-edge, white-knuckle driving. 
  • Porsche began developing it in early 2024, and it is being developed by professional drivers on renowned tracks such as Monza and Weissach.
  • It will eventually replace the current Cup car in the same series such as Porsche Supercup and Carrera Cup North America—the events that cultivate the next generation of racer stars.

What’s Different This Time? 

Instead of merely changing the design, Porsche has changed the whole car! Here is what's different: 

  • New aero package which now has larger hood vents, a new front splitter, and new wider rear for better loads and downforce. 
  • Changes to the front bumper which now has trapezoidal air intakes for better cooling, especially during serious racing. 
  • Body work designed for better airflow making it cut through the air better. 

Translation: it looks mean and it performs meaner.

Driver-Centric Cockpit Redesign

When it comes to the inside, it's all about being inside for the driver. Porsche revamped the interior to give racers a more direct input, visibility, and comfort on laps that matter.

  • Updated digital dash to sit just below the steering wheel with clearer displays and more feedback.
  • Brand new multi-function steering wheel, drawing inspiration from Porsche's bigger brothers in the racing space.
  • Pedals move into refined position leaving the driver and seat at a straight position helping the driver keep their head level and keep focus for longer driving stints.

It's like you have a racing control center tailored for driver's maximum performance.

Same Engine, Sharper Performance

Under the hood, the vehicle features a naturally aspirated 4.0-liter flat-six engine that still produces close to 503 horsepower. However, in addition to suspension and additional tuning, the car has better:

  • Cornering response
  • Smoothness in power delivery
  • Grip on launch

It's not just about getting from A to B quickly, this version was built for greater feel and confidence when cornering - where races are won in the first place.

 A More Sustainable Way to Race

What’s really awesome? Porsche is testing this car with its new low-carbon eFuel - essentially a synthetic fuel made from renewable resources.

  • 66% reduction in COâ‚‚ emissions compared to traditional gas
  • No large-scale engine re-design
  • Currently in use in Porsche Supercup racing

So, you get to enjoy the thrill of racing without trashing the planet. That’s what you call future-focused.

When Can We See It in Action?

  • Starts production: fall 2025
  • Scheduled to debut on track in the 2026 season
  • Expected to appear in Carrera Cup North America, with tracks like Sebring, Laguna Seca, or COTA as possible options

So, if you’re going to check out the stands, or following Porsche racing ladder in 2024, get ready. This car is going to be everywhere.
