The '''Performance Index''' (commonly abbreviated as '''P.I.''' or '''PI''') is a car performance measuring system that has been used since ''[[Forza Motorsport 2]]''.
+
The '''Performance Index''' - abbreviated as ''P.I.'' or ''PI'' - is a car performance measuring system featured in ''[[Forza Motorsport 2]]'' and all subsequent titles.
   
== Overview ==
+
==Factors==
The Performance Index displays a car's overall performance value, determined by five factors rated from 0.0 to 10.0 (with a minimum of 3.0) and usually influenced by weight:
+
The Performance Index evaluates five performance factors scored from 3.0 to 10.0 and assigns a car an alphanumeric performance class starting from 0 and capping at 999 or 1000. Classes group similar cars together, allowing race events to permit entry to certain cars to enable a competitive environment.
* '''Speed:''' How fast the vehicle can go at maximum speed. This is determined by engine power and transmission gearing. Cars that can reach {{speed|268}} or higher, like the [[Koenigsegg One:1]] and [[Plymouth GTX Fast & Furious Edition]], usually have a Speed rating of 10.0.
 
* '''Handling:''' How well the car can handle corners. This is determined by lateral G forces at {{speed|60}} and {{speed|120}}. The Formula One cars and hypercars usually have the best handling in the series.
 
* '''Acceleration:''' How quickly the car can accelerate. This is determined by its 0 - {{speed|60}} and 0 - {{speed|100}} ratings. AWD cars usually have higher Acceleration values than their RWD counterparts.
 
* '''Launch:''' The capability of a car launching from a standing start efficiently (e.g. with minimal to no wheelspin). AWD cars and rear-engine cars usually have the highest Launch values. Launch ratings are normally not shown in ''[[Forza Motorsport 6]]'' and ''[[Forza Motorsport 7]]''.
 
* '''Braking:''' How well the car can brake to a stop. This is determined by distances required for {{speed|60}} - 0 and {{speed|100}} - 0.
 
   
It is shown by letters (F to A, then S, S1, S2, R, P, U, or X) and then a number starting from 100 and capping at either 999 or 1000 (e.g. P 998).
+
*'''Speed''' evaluates top speed determined by engine performance and transmission gearing.
  +
*'''Handling''' evaluates maximum cornering speeds determined by lateral G force values at {{speed|60}} and {{speed|120}}.
  +
*'''Acceleration''' evaluates acceleration to top speed determined by 0 to {{speed|60}} and {{speed|100}} times.
  +
*'''Launch''' evaluates acceleration from a standstill determined by 0 to {{speed|60}} and {{speed|100}} times.
  +
*'''Braking''' evaluates braking distances determined by braking distances required for {{speed|60}} and {{speed|100}} to 0.
  +
*'''Class''' evaluates overall performance determined by a car's lap time on a simulated test track.<ref>{{ref|https://support.forzamotorsport.net/hc/en-us/articles/360005372033-Performance-Index-and-Classes|Performance Index and Classes|forzamotorsport.net|12-01-2018}}</ref>
   
Any vehicle's performance index can be increased by applying power-improving and weight-saving upgrades. Players can also decrease their P.I. value by adding weight and using a drivetrain conversion.

In the ''Forza Horizon'' games, there are no cars ranked <span style="color:#19A83C;">'''X 999'''</span> by default.

FH3 PerformanceIndex

The Performance Index - abbreviated as P.I. or PI - is a car performance measuring system featured in Forza Motorsport 2 and all subsequent titles.

Factors

The Performance Index evaluates five performance factors scored from 3.0 to 10.0 and assigns a car an alphanumeric performance class starting from 0 and capping at 999 or 1000. Classes group similar cars together, allowing race events to permit entry to certain cars to enable a competitive environment.

  • Speed evaluates top speed determined by engine performance and transmission gearing.
  • Handling evaluates maximum cornering speeds determined by lateral G force values at 60 mph (97 km/h) and 120 mph (193 km/h).
  • Acceleration evaluates acceleration to top speed determined by 0 to 60 mph (97 km/h) and 100 mph (161 km/h) times.
  • Launch evaluates acceleration from a standstill determined by 0 to 60 mph (97 km/h) and 100 mph (161 km/h) times.
  • Braking evaluates braking distances determined by braking distances required for 60 mph (97 km/h) and 100 mph (161 km/h) to 0.
  • Class evaluates overall performance determined by a car's lap time on a simulated test track.[1]
