Pagani Huayra R: The “Arte in Pista” Rework

The Huayra R is a clean-sheet design, powered by a naturally aspirated heart that revs higher and screams louder than any previous Pagani. This overhaul removes the “street car” DNA and implements a pure, prototype-level racing simulation.

The V12-R: 9,000 RPM Symphony

In collaboration with HWA AG, the Huayra R engine is a masterpiece of lightness and power:

  • Engine & Torque Rework: Calibrated to an authentic 850 hp @ 8,250 rpm and 750 Nm of torque. The engine limiter has been raised to 9,000 rpm, and the power curve has been shifted to reward high-RPM driving, capturing that early ’90s V12 F1 character.
  • Sound Rework: The audio has been specifically retuned to accommodate the 9,000 rpm ceiling, ensuring the screaming Inconel exhaust notes don’t distort or “loop” unnaturally at high revs.
  • Drivetrain Accuracy: After analyzing onboard footage, we have updated the 6-speed sequential gearbox with precise racing ratios. The shift logic is now instantaneous, allowing you to stay perfectly within the power band through the Variante del Rettifilo.

Aerodynamics: The Monza Calibration

The Huayra R was designed to generate 1,000 kg of downforce at 320 km/h.

  • Drag Reduction: We have specifically reduced the aero drag to match real-world data from Monza, where the car is documented hitting 323 km/h on the main straight. This ensures the car has the correct “slipstream” behavior for endurance racing.
  • Aero Balance: Re-calibrated the downforce distribution to a 46% front / 54% rear split. This makes the car incredibly stable under heavy braking while providing enough front-end bite for high-speed direction changes in the Lesmo corners.

Visual & Technical Updates (23/12/25)

  • Carbon Fiber Refinement: Updated the skin shaders to include two distinct carbon finishes: a High-Gloss Clear Coat and a Raw Matte Carbon version. Both utilize improved PBR (Physically Based Rendering) values in the extension.
  • Suspension Geometry: Reworked the suspension to handle the massive aero loads, preventing the car from “bottoming out” at high speeds while maintaining the mechanical compliance needed for track curbs.
  • AI Calibration: The AI has been retrained to handle the 9,000 rpm redline and the car’s specific braking points. They are now much more competitive in high-speed draft battles.

Installation Requirements

Note: This physics and graphics configuration is designed for compatibility with the EX Mods model.

  • Required: A valid installation of the base model by EX Mods is required to apply these technical updates.
  • Included: The 7z archive contains updated dataextensionui, and updated skins (Gloss/Matte).
  • Method: Replace the folders in your content/cars/pagani_huayra_r_ex directory.
