The Performance Factor (Pf) explained

The “General performance Variable” is a method of utilizing conveniently measurable technological characteristics of automobiles to give them a “Pf” price, which is utilised to classify the automobiles into distinctive groups. Rivals input details about their auto that represent the elements affecting the car’s general performance. This calculation works by using these aspects, racing weight, engine, aerodynamic, transmission and chassis parameters, to develop the “Pf” benefit.

In addition to the European Hill Climb Championships, Pf is applied in a dozen national championships in Europe and the Center East, the most current adopters currently being Austria, Luxembourg and Germany. Pf is opening a new period to determine lessons or teams in motosport and its rules may possibly be utilised in other disciplines in fact some Slalom organizers presently use it. 

Pf in Classification 1 is now well proven, following three decades of experimentation and two comprehensive seasons of European Championship use. The new 2023 version of the Pf for Classification 1 will be available on-line in March by way of www.fiaperformancefactor.com. This new edition will need all drivers to get hold of a technical sheet for their automobile, recognizable by the code “Y4” which will be connected with the Pf ID quantity.

For 2023 the bare minimum excess weight calculation for just about every Class 1 auto is the significant improve. This replaces the stepped scale of minimum amount weight employing engine capability only. The new method is based on the Pf motor component price, “Pfe”, employing a graduated bodyweight scale. Two pounds scales will be released, based on the amount of security gear utilised in the vehicle. The decreased minimal body weight scale will involve the protection cage (rollcage) be Homologated by the FIA or Qualified by an ASN, the seat is complying to the most modern FIA specifications (FIA 8855-2021 or FIA 8862-2009) and the FIA fuel tank is within just the described perimeter of the security construction. The bare minimum fat benefit is revealed on the website calculation and on every single car’s special Pf technological sheet. This is an addition output to the rivals declared minimal ‘racing weight’.

Pf simulations executed on the internet, and the Pf technological sheets will continue to be cost-free of charge in 2023. However, from 2024 time, a price will be billed for issuing the Pf specialized sheets (modalities to be defined), payable from the website by credit card. 

The Hill Climb willpower now has dedicated technological polices, Write-up 258 in Appendix J to the International Sporting Code. Group 1 vehicles use Report 258-1 (relevant from 1.1.2023) and Report 258-2 is committed to Class 2 cars and trucks (applicable from 1.1.2024).

In 2023, in the European Championship and Global Hill Climb Cup, Class 2 cars and trucks will have to comply with a specialized appendix to the relevant Sporting Regulations, which particulars prerequisites for, amid other items, rev boundaries for by natural means-aspirated engines, a 42.25 mm restrictor for turbocharged engines, the use of an FIA-authorised information acquisition system, a new least body weight scale and a minimum floor clearance of 45mm. Comprehensive restrictions can be identified at https://www.fia.com/regulation/group/738

Hill Climb Commission President Dusan Koblisek claimed: “The Functionality element methodology is starting to be the backbone of Hill Climbing sport. Complex working groups have been established up to aid watch its application for shut cars and trucks. The Pf unquestionably aids the regional, nationwide and worldwide progress of Hill Climb and offers the self-control a dependable and harmonised technological technique, with inclusive virtues.”
