This video explains the concept of a "Purist" build in Forza Horizon 5, which excludes engine swaps, drivetrain swaps, and Forza aero. The presenter details how the PI (Performance Index) system works and how to exploit it for better car builds. The video then walks through various upgrade categories, including tires, aero, suspension, power, drivetrain, and tuning, providing specific recommendations and strategies for optimizing car performance within the game's mechanics.
The video offers a deep dive into building and tuning "Purist" cars in Forza Horizon 5, emphasizing how to manipulate the game's Performance Index (PI) system for competitive advantage.
Understanding the PI System for Exploitation: The core idea is that the PI system, which assigns a performance rating to cars, is based on an AI test drive on stock tunes across base game asphalt tracks. This creates opportunities for players to "lie" to the system. Key exploits include:
Key Upgrade Categories and Nuances:
Tires:
Aero:
Suspension:
Power Upgrades:
Tuning Sliders (Detailed Nuances):
The video stresses that these are guidelines, and exceptions exist. Players are encouraged to test and tune based on their car and driving style.
