The arrival of the Porsche 911 Cup (992.2) in the 2026 Season 1 build marks one of the most significant updates in the history of iRacingโs one-make racing. This new car is not just a visual upgrade. It is a complete mechanical overhaul that brings the simulation in line with real-world 2026 specifications.
The Transition from 992.1 to 992.2
For years, the 992.1 model was the gold standard for high-skill, analog racing on iRacing. However, the real-world Porsche Supercup is moving to the 992.2 platform for 2026. Consequently, iRacing has retired the 992.1 to Legacy content.+1
The new Porsche 911 Cup (992.2) features a 10-horsepower increase, bringing the total output to 520 horsepower. This extra power, combined with refined aerodynamics, makes the car roughly 1 to 1.5 seconds faster per lap than the previous model.
Major Physics and Handling Overhauls
The driving experience has changed fundamentally due to several key updates in the physics engine.
Revised Suspension and Aero Geometry
iRacing engineers reworked the front suspension and aerodynamics to improve front-axle response. The new car understeers less and bites harder into corners. Additionally, the rear aerodynamics were updated with a new wing design that provides more consistent airflow and less turbulence.+1
The Introduction of ABS and Traction Control
The most discussed change is the addition of standard ABS and Traction Control.
- ABS Implementation: The system uses “split front and rear axle slip targets” to simulate real-world electronic aids. This allows for much more aggressive braking while maintaining stability.
- Traction Control (TC): While the Porsche Cup is already rear-heavy and has excellent traction, the new TC system helps catch slides during aggressive corner exits.
New Tire and Brake Specifications
The car utilizes the latest dry and wet tire models developed for iRacing’s GT3 and GT4 classes. Furthermore, the braking system now includes a range of pad options, including delivery and endurance specifications. These pads change how heat builds up and how the brakes fade over long stints.+1
Nรผrburgring Nordschleife Rules Package
The Porsche 911 Cup (992.2) includes a specific physics package for the Nordschleife.
- Mandatory Specs: The car uses fixed spring rates and increased ride heights to handle the track’s bumps.
- Aero Updates: Front dive planes are added to increase downforce on the technical sections of the Green Hell.
- Power Adjustment: The car runs a “quiet exhaust” configuration at the Ring, which slightly reduces engine power to match real-world noise regulations.
