Forza Motorsport 7 categorizes cars into various classes based on their Performance Index (PI). Understanding this system is fundamental to competitive racing and car building.
Car Classes:
Cars are grouped into classes from D (lowest performance) to X (highest performance). The classes are: D, C, B, A, S, R, P, X. Each class has a specific PI range.
- D Class: PI 100-300 (e.g., older sedans, compacts)
- C Class: PI 301-400 (e.g., hot hatches, classic sports cars)
- B Class: PI 401-500 (e.g., modern sports cars, muscle cars)
- A Class: PI 501-600 (e.g., high-performance sports cars, entry-level supercars)
- S Class: PI 601-700 (e.g., supercars, high-end GT cars)
- R Class: PI 701-800 (e.g., hypercars, race-bred GT cars)
- P Class: PI 801-900 (e.g., prototype racers, extreme hypercars)
- X Class: PI 901-999 (e.g., Formula 1 cars, purpose-built track monsters)
Performance Index (PI):
The PI is a numerical value that represents a car's overall performance. It's calculated based on factors like horsepower, torque, weight, grip, and aerodynamics. When you upgrade a car, its PI will change. The goal in many races is to build a car that maximizes its performance within a specific class's PI limit.
When buying or upgrading cars, always pay attention to their class and PI. This ensures you're selecting the right vehicle for the event and can tune it effectively to meet race requirements. A higher PI generally means a faster car, but skillful driving is always paramount.
