Definition of Homologation
Homologation is the official certification made by the FIA that a minimum number of cars of a specific model has been made on series-production terms to justify classification in Production Cars (Group "N"), Touring Cars (Group "A"). Application for homologation shall be submitted to the FIA by the manufacturer of the Country in which the vehicle is manufactured and shall entail the drawing up of a homologation form. It must be established in accordance with the specific regulations called "Regulations for homologation", laid down by the FIA. Homologation of a series-produced car will become null and void 7 years after the date on which the series-production of the said model has been stopped (series-production under 10% of the minimum production of the group considered).
- All cars recognised by the FIA will be the subject of a descriptive form called the Homologation Form on which shall be entered all data enabling identification of the said model.
- This Homologation Form defines the series as indicated by the manufacturer. According to the group in which the competitors race, the modification limits allowed in national competition for the series are stated in Appendix J.
- The presentation of the forms at scrutineering and / or at the start may be required by the organisers who will be entitled to refuse the participation of the entrant in the event in case of non-presentation.
- Likewise, if a Group "A" car fitted with a kit variant concerning the Chassis / Shell is used, the original certificate supplied at the time of mounting by a centre approved by the manufacturer may be presented.
- Should the date for the coming in to force of a homologation form fall during an event, this form will be valid for that event throughout the duration of the said event.
- With regard to Production Cars (Group N), apart from the specific form for this group, the Touring Cars (Group A) form must also be submitted.
In case of any doubt remaining after the checking of a model of car against its homologation form, the scrutineers should refer either to the maintenance booklet published for the use of the make's distributors or to the general catalogue in which are listed all spare parts.
In case of lack of sufficient accurate documentation, scrutineers may carry out direct scrutineering by comparison with an identical part available from a concessionaire. It will be up to the competitor to obtain the Homologation Form concerning his car from the FIA.
Contents and Description of a Homologation form
A form breaks down in the following way:
- A basic form giving a description of the basic model.
- At a later stage, a certain number of additional sheets describing "homologation extensions" can be added, which can be "variants", or "errata" or "evolutions".
- Variants (VF, VO, VK). These are either supply variants (VF) (two suppliers providing the same part for the manufacturer and the client does not have the possibility of choice), or options (VO) (supplied on request and available at the concessionnaires), or "kits" (VK) supplied on request and available at the concessionnaires.
- Erratum (ER). Replaces and cancels an incorrect piece of information previously supplied by the constructor on a form.
- Evolution (ET, ES). Characterises modifications made on a permanent basis to the basic model (complete cessation of the production of the car in its original form in the case of the evolution of the type (ET), or sporting evolution (ES) intended to render a model more competitive.
Use of Homologation
1) Variants (VF, VO, VK)
The competitor may use any variant or any part of a variant as he wishes, only on condition that all the technical data of the vehicle, so designed, conforms to that described on the homologation form applicable to the car, or expressly allowed by Appendix J.
The combination of several VOs on the following parts is prohibited: Turbocharger, brakes and gearbox.
For example, the fitting of a brake calliper as defined on a variant form is only possible if the dimensions of the brake linings, etc. obtained in this way, are indicated on a form applicable to the car in question. (For Production Cars (Group N), see also Art. 254.2).
As far as kit-variants (VK) are concerned, they may not be used only under the conditions indicated by the manufacturer on the homologation form. This concerns in particular those groups of parts which must be considered as a whole by the competitor, and the specifications which are to be respected, if applicable.
2) Evolution of the type (ET)
(For Production Cars - Group N, see also Art. 254.2)
The car must comply with a given stage of evolution (independent of the date when it left the factory), and thus an evolution must be wholly applied or not at all.
Besides, from the moment a competitor has chosen a particular evolution, all the previous evolutions should be applied, except where they are incompatible: for example, if two brake evolutions happen one after another, only that corresponding to the date of the stage of evolution of the car will be used.
3) Sporting evolution (ES)
Since the ES form refers to a previous extension, or to the basic form, the car must correspond to the stage of evolution corresponding to this reference; moreover, the Sporting Evolution must be applied in full.
