TITLE II

DEFINITIONS AND GENERAL PRESCRIPTIONSCONCERNING CARS OF CATEGORIES A AND B

(5.000).(1.000).(500).(50).

Art. 252. - Definitions al Reeegnixed production cars: carsof which the series-production of a certain number of identical(see definition of this word hereafter) cars, has been completed

-1-

within a certain period of time, and which are meant for thenormal sale (see below) to the individual purchaser. This period'of time is of 12 consecutive months. The checking of the existingminimum production enables the AC.N. to apply to the F.I.A.for recognition (see this word below).

b) Special cars: cars which have nothing or which have nomore to do with a series-production vehicle, either that only oneof the type has been built, or that the number of units whichhas been bui It is inferior to what is required for the group forwhich t'he minimum number of units annually produced is thesmallest, or that although they originate from a series-productioncar, they have been modified or equipped with new accessoriesto the point that their series-production nature has been lost.

c) Racing cars: cars manufactured solely for speed races on il

circuit or a closed course. These cars are generally defined bvthe international racina formulae the specifications of which arefixed by the F.I.A for a certain period of time. Racing carsnot being defined by any international formula are said to be« formule libre» and their specifications must in that case beset out in the supplementary regulations of the event.

d) Identical: by « identical» cars are meant cars belongingto one and the same fabrication series and which have thesame coachwork (outside and inside), same mechanical compo-nents and same chassis (even though this chassis may be amal-gamated with the coachwork in case of a unitary construction).

« Mechanical cornponents » include all parts for the pro-pulsion, suspension, steering and braking system and all acces-sories whether moving or not which are necessary for theirnormal functioning (such as for instance, electric accessories),

By chassis is meant the structure of the car which holdsmechanical components and coachwork together, and includesany structural part which is located below the horizontal planepassing through the center of the wheel hubs.

e) Minimum production: this minimum production, differentfor each group of cars, applies to cars which are identical, themanufacturing of which has been fully completed within il periodof 12 consecutive months.

E) Normal sale: means the distribution of cars to individualpurchasers through the normal commercial channels of themanufacturer.

-2-

g) Recognition: is the official certification made by the F.I.A.that a minimum number of cars of a specific model has beenmade on series-production terms to justify classification ingroup l, 2, 3 or 4 of these regulations. Application for reco-gnition shall be submitted to the F.I.A. by the A.C.N. of thecountry in which the vehicle is manufactured and shall entailthe drawing up of a recognition form (see below). It must beestablished in accordance with the special regulations, called« Regulations for Recognition», laid down by the F.I.A., anda manufacturer wishing to obtain the recognition of his model (s)must undertake to abide by their prescriptions. Recognition wi IIonly be granted to car-models which were still in productionon 1st January 1957 or the production of which was startedafter that date. Recognition of a series-produced car will becomevoid 4 years after the date on which the series-production ofthe said model has been stopped.

Recognition of a model may only be valid for one group.The transferring of a previously recognized model from one groupto another will therefore nullify the effect of the said previousrecognition.

h) Re'cognition forms: al! eNS recognized by the F.I.A. shallbo the subject of a descriotive form called Recognition form onwhich shall be entered all data enabling identification of thesaid model.

To this effect only the standard recognition forms andstandard additional form for « normal evolution of the type)and « variant» approved by the F.I.A shall be used by allAC.N.s.

The production of the forms at scrutineering and/or at thestart may be required by the promoters who will be entitled torefuse the participation of the entrant in the event in case ofnon-production.

In case of any doubt remaining after the checking of a modelof car against its recognition form, the scrutineers would haveto refer either to the maintainance booklet published for theuse of the make's distributors or to the general catalogue inwhich are listed all spare parts.

It will rest with the competitor to obtain the recognitionform and, if need be, the additional forms concerning his car,from the AC.N. of the manufacturing country of the vehicle.

i) Cylinder-capacity classes: the cars shall be distributed into

-:; -

the following 13 classes, according to their cylinder-capacity1. Cvinder capacity inferior or equal to 500 cc.2. Cylinder capacity exceeding 500 cc.

and inferior or equal to 600 cc.3. Cylinder capacity exceeding 600 cc.

and inferior or equal to 700 cc.4. Cylinder capacity exceeding 700 cc.

and inferior or equal to 850 cc.5. Cylinder capacity exceeding 850 cc.

and inferior or equal to 1.000 cc.6. Cylinder capacity exceeding 1.000 cc.

and inferior or equal to 1.150 cc.7. Cylinder capacity exceeding 1.150 cc.

and inferior or equal to 1.300 cc.S. Cylinder capacity exceeding 1.300 cc.

and inferior or equal to 1.600 cc.9. Cylinder capacity exceeding 1.600 cc.

and inferior or equal to 2.000 cc.10. Cylinder capacity exceeding 2.000 cc.

and inferior or equal ta 2.500 cc.1 1. Cylinder capacity exceeding 2.500 cc.

and inferior or equal ta 3.000 cc.12. Cylinder capacity exceeding 3.000 cc.

and inferior or equal to 5.000 cc.13. Cylinder capacity exceeding 5.000 cc.

Re<.(ulations intended for soecific events mav provide one orseveral sub-divisions of class 13. There shall be no sub-divisionof the other classes.

The above mentioned classification will apply only to non-supercharged engines.

Unless otherwise specified in special provisions set up bythe F.I.A. for a certain category of events, the organizers arenot bound to include all the above mentioned classes in thesupplemenMry regulations, and, furthermore they are free togroup two or more consecutive classes, according to the parti-cular circumstances of their events.

i) Supercharging: if the enaine of a car i,..dudes a seoaratedevice used for supercharging it, the 'nominal cylinder-capacitywill be multiplied by lA and 'he car will pass into the classcorresponding to the nominal volume thus obtained. The new

4-

cylinder capacity of the car shall always be considered as the realone. This shall particularly be the case for assigning the car toits cylinder-capacity class, and the car will be treated in allcircumstances as if its cylinder capacity thus increased was itsreal capacity. Especially in regard to its classification per cylinder-capacity class, its inside dimensions, its minimum number ofseats, etc.

A dynamic air inlet for ducting the air from the atmosphereinto the engine intake will not be considered as a superchargingdevice.

k) Coachwork: bv coachwork is meant:externally: all parts of the car licked by the air-streamand situated above a plane passing through the centreof the wheel hubs.internally: all visible parts of the passenger compartment.

Coachworks are differentiated as follows:1) completely closed coachworks,2) completely open coachworks,3) convertible coachworks: with a hood in either supple

(drop-head) or rigid (hard-top) material.Coachworks of one same minimum series shall be identical

with the only exception of a «sun roof ».However, if a model has its coachwork equipped with a

specific number of doors and has been recognized on the basisof a given minimum series, similar recognition may be grantedto another coachwork with a different number of doors whenits minimum production reaches 50 % of the figure necessaryfor recognition of the basic series, providing thar both modelshave the following common caracteristics:

I) a coachwork of similar shape, i.e. of which the generalappearance is basically the same and which has not beenmodified beyond what is necessary to change from a fourdoor version to a two door version (or vice-versa)

2) exactly identical mechanical parts;3) the same wheelbase, track and number of seats;4) at least the same weight;5) an F.I.A. decision to recognize this variant coachwork

and to draw up an additional « variant» recognition form.As far as convertible cars are concerned, these must comply

in all respects with the specifications applying to closed carsif they run an event 'under ,this form, or with the specifications

5.-

concerning open cars if they run with the hood down or thehardtop removed.

I) Minimum weight: is the real minimum weight of the emptycar (without persons or luggage aboard) fully equipped and readyfor del ivery to the purchaser. It shall consequently include aspare-wheel equipped with a tyre similar to those mounted onat least 2 of the 4 wheels, and none of the accessories normallymounted on the least expensive model of the series concernedbeing removed, except for the normally supplied repairkit (jack,tool-kit). All liquid tanks lof lubrication, cooling system, braking,heating system, if need be). except for the fuel tank, mustbe full.

The minimum weight of the car mentioned on the recognitionform shall be strictly respected. Any lightening of the car byremoval or replacement of parts, aiming at reducing its weight,is prohibited.

Art. 253. - Prescriptions common to all cars of cate-gories A and B.

a) Chassis, ground clearance, steering lock: the car, suppliedwith enough fuel for starting the event, its oil and water tanksfull, must be able to drive over - under the power of itsengine and with its driver at the steering-wheel - a mass of80 X 80 cm and 10 cm high.

The maximum steering radius shall be 6,75 m which meansthat the car must be able to make a complete turn in bOl':,directions without the wheels going beyond two parallel linesdrawn on the ground 13,50 m apart.

b) Coachwork: rni.virnurn inside dimensions and minimumnumber of seats: cars shall be equipped with a minimum oftwo seats or a minimum of four seats according to the group inwhich they seek recognition and, within a same group, accordingto their engine cylinder-capacity.

For each group specified in these regulations, the minimumnumber of seats is listed hereafter and the minimum insidedimensions for both cases are indicated in the following para-graphs.

1st case (see diagram 1): car equipped with 4 (or more)seats.

The height at the front (B) is measured between the lowestsurface of the front seat, compressed by a standard mass of

-6-

60 kgs (see diagram 2) and the ceiling (the padding if any,may be compressed). Should the backrest of the front seat(s) beinclined backwards, the protected height must also be measuredat the same angle as the inclination of the backrest.

- If the front seats are separate, the measurement ismade in the middle of the two seats. In case of adjustable frontseats, the seats will be placed in medium position.

- If there is a common front seat, the measurement ismade at 25 Cm from the center line of the car.

The height at the back (D) is measured between the cushionof the rear seat, compressed hy the standard mass, and theceiling (the padding if any, may be compressed) at 25 cm fromthe center line of t'he car. Should the backrest of the rear seatbe inclined backwards, the protected height must also be measuredat the same angle as the incliriat ion of the back res t.

The width over the front seats (C) is measured along thevertical plane passing through the center of the standard mass,30 em above the compressed seat, and between the upper stripof each front door.

The width over the back seats (E) is measured along thevertical plane passing through the center of the standard mass,30 em above the compressed seat and between the upper stripof each back door, or at the same height as for the frontseats when there are no rear-doors.

The minimum dimensions (in centimetres) are the following:

Cyl inder -capaci ty B C DUp to 700 cc. 85 100From 700 t 2.000 cc. 85 J JO 85Over 2.000 cc. 90 120 85

E

Moreover, in order to be considered as a four-seater, a mode)must fulfill certain conditions regarding its rear-seating capacity.These conditions are the following (see diagram 3) :

I. - I must be at least 90 % of L ;m must be at least 85 % of M ;n must be at least 80 % of N ;p must be at least 80 % of k + m.

2. - k must measure at least 15 cm and the minimum

7-

measures for the footspace of the rear passengers must be : 32 emlong, 5 cm high and (for each one of the two passengers) 25 emwide.

3. - the space available for the rear passengers must meetthe following condition: k + I + m = 95 em minimum.

of the rear seat (s) iscannot be considered as

4. - cars in which the backinclined forward beyond the verticalfour-seaters.

The measuring of the above dimensions must be carried outunder the following conditions:

the front seat. if adjustable, must be placed in its normalciriving posi tion, i.e. : K + L + M must measure at least 12e em.

if the front seats have re;::lining backs-rests, these shouldbe set at an inclination of 15° backwards.

K is measured horiz.ontally from the brake pedal (at rest)to the foremost point of the front seat; k i3 measured horizon-tally at a height equal to I) from the back of the front seatto the foremost ooint of the rear seat.

L and I are measured vertically from the highest point of thecushion of the seat to the floor of the car. At the front L mustbe measured at the usual resring-place of the driver's heels.

Ivl and m are measured horizontally from the foremost pointof the seat to the backrest to be measured at a height of L (1).

Two specific cases must be distinguished:

1) bucket-seats: the measuring must be taken on the centerline of each seat.

2) common seat: measuring must be carried out at 25 cmfrom the longitudinal "xis of the vehicle.

However, for the rear seat(s) measuring must be made inIhe same vertical plane as for the front seats.

N (and n) are measured vertically from the highest pointof the backrest to the highest point of the cushion of the seat.

I) is measured (in the same vertical plane as m) horizontallyfrom the rearmost point of the backrest of the front seat to thebackrest of the rear seat.

For the above-mentioned measurements, seats must not beoccupied.

2nd case (see diagram 4 and 5): cars with a minimum of2 seats.

-8-

The two seats must be distributed equally on either sideof the longitudinal centerline of the car and at the same level,regardless of their normal olay for adjusting them to the size ofthe driver. The location provided for placing or housing the seatsmust have a minimum width of 40 cm maintained all along thedepth of the seat.

The «protected height» shall be at least 80 cm measuredfrom the cushion of the seat compressed by the standard mass(see diagram 2) to the ceiling (any existing padding beingcompressed) in cars with closed coach-work and 80 cm fromthe surface of the seat compressed by the standard mass (seediagram 2) to t·he upper edge of the windscreen (measuredver tically through the centre of the standard mass) in case ofopen cars.

The minimum interior width over the front seats (see measu-rement C) shall be of 100 em in cars with a cylinder-capacityinferior or equal to 700 cc, 1 10 cm in cars with a cylinder-capacity from 700 cc to 2.000 cc and 120 em in cars with awith a cylinder-capacity exceeding 2.000 cc. The minimumwidth of foot-space (for each person) must be at least 25 emmeasured perpendicularly to the centerline of the car, plumbwith the pedals.

ci Windshield - Windshield wiper; a windshield made atsafetv glass is compulsory. In all series-production cars it shall bemade of the materia' originally provided by the manufacturer. Itshall be equipped with at least one automatic wiper sweeping asufficient area to enable the driver to distinctly see the roadfrom his seat.

The windshield shall comply with the following requirements:1) be placed symetrically with regard to the centerline at

the car;2) have a minimum height of 25 em, maintained between

two points symetrically placed with regard to the center-line of the car and of which one is determined by thevertical line passing through the center of the steering-wheel. There must furthermore be at least 45 cm betweenthe two said points.

3) have a minimum width of 90 cm; chord measured athalf its vertical height.

Shall be considered as being the windshield, only the glassarea through which one has an entirely free vision towards thefront, without being limited by any outside opaque projectionapart from the bulge of the mudguards which cover the frontwheels.

d) Mudguards: 5:1.311 be of permanent nature and firmly fixed.They shall proje:t over the wheels and provide efficient

covering of 'It least one third of their circumference, and atleast the width of the tyre.

In those cars where mudguards are enterely or partly overhungby the body structure, the combination mudguards-body or thebody alone shall nevertheless meet the above protection requi-rements.

Mudguards must be solid with the body, there being nogap between them.

e) Hood: open or convertible cars shall be equipped with ahood fitting exactly, and without any intermediary device, to thewindshield, the door windows or side panels, and the rear ofthe coachwork.

The hood ,may not interfere with the opening of the doors.It shall Jnclude a rear window, the minimum dimensions ofwhich are' specified in the present article (see below «rearwindow »}.

I t must be capable of being used during all or part of theevent. The supplementary regulations may specify in which stateconvertible body cars must run (as closed cars or open cars,otherwise it shall be at the discretion of the entrant) but thehood if not fitted on the car must almays remain aboard the carduring the whole at the event, The hood may be replaced bya hard top subject to the same conditions as for a hood.

f) Doors: all vehicles shall be fitted with at least one rigiddoor on each side, with closing devices and hinges which maynot be located on the rear-door post, nor on the door-sill. Thedimensions of th", lower door panel (the part which is normallyopaque) must be such as to allow a rectangle of at least 50 cmwide and 30 cm high being inserted in it. Cars with sliding-doorswill not be allowed unless they include a safety system enablingil quick and easy evacuation of the car's occupants in case ofan accident.

Cars with closed or convertible coachwork shall have doorsequipped with movable windows at the material provided by themanufacturer for the considered model, liable to be opened overat least one third of their surface in order to provide for venti-lation, each window having a minimum width of 40 em and aminimum height of 25 em.

When opened, the doors must give free access to the seats,They must be made in such a way that they never restrict thelateral view of the driver.

gl Rear view: this shall be provided by an inside mirorcommanding 3 rear window measuring at least 10 cm verticallymaintained along a width of at least 50 em. However, if thestraight line connecting the upper and lower edges of the rearwindow opening makes an angle inferior to 20<> with the hori-zontal, when the car complies with the same specifications asthose required for checking the ground-clearance (see art. 253),the rear view must be efficiently obtained by other means (twooutside mirrors or any other system of equivalent efficiency).

h} Luggage trunk: a covered space shall be provided which isan integral part of the coachwork but outside the space occupiedby the passenger seats.

This space shall be such as to enable to carry without specialdifficulty a number of suitcases, sheltered from rain or dirt

which varies according to the cylinder-capacity of the engineequipping the car [see below), of the following minimum dimen-sions: 60 cm X 40 cm X 20 cm.Cyl inder-capacity inferior or equal to 2.000 cc: 1 suit-case,Cylinder-capacity superior to 2.000 cc : 2 suit-cases.

However, in cars having inside dimensions which are inferiorto the minima laid down in article 253 b to allow classificationas a four-seater, but which contain a compartment behind thefront seats liable to receive passengers, this compartment maybe taken into account as luggage space whether or not it hasbeen equicped tor this purpose but without modifying any of theoriginal parts.

i) Starting: cars must be equipped with a device and itssource of power for automatically starting the engine and ableto be actuated by the driver sitting at the wheel.

j) Fuel tanks: the total capacity of the fuel tanks (mainand additional) must net exceed the following limits:

Cars up to 700 cc of engine. cylinder-capacity: 60 I.Cars from 700 cc to 1 .000 cc cylinder-capacity: 70 I.

Cars exceeding 5.000 cc » : 160 I.Will be considered as a fuel tank any container holding fuel

which can flow out by any method either to the main-tank ordirectly to the engine.

The filling-port(s) (and vents) of each tank must alwaysbe outside the passenger-compartment and be enti rely leak-proof.

k) Spare-wheels: ë:11 cars shall be equipped with at leastone spare wheel with its tyre occupying the position providedfor by the manufacturer which may not encroach upon the spaceprovided for luggage.

The spare wheel must be equipped with a tyre of the samedimensions as those fitted on at least two wheel's of the car.

I) SilÉi'ncer (muffier) and exhaust system: even when the

-16~

specific provisions for a group allow replacement of the originalmuffler, cars competing in an open road event shall always beequipped with an exhaust muffler complying with the roadregulations of the country( ies) through which the event is run.

For events run exclusively on closed circuits,' the supple-mentary regulations may authorize modification, replacement orremoval of the exhaust muffier.

The outlet pipes of the muffler shall be directed eitherre~-wards or sideways. If the outlet oioes are pointing rearwards,their orifices shall be placed at a height neither superior to 45 cmnor below lO em ; they 'shall not protrude by more than 15 embeyond the overall length of the car. If the exhaust pipes aredirected sideways, their orifices must be located aft of a verticalI ine passing through the wheelbase center and may not projectin any way beyond side of the coachwork. Adequate protectionshall be provided in order to prevent heated pipes from causingburns.

+

m) Safety devices: for cars competing in events which arespeed races exclusively the following safety devices are foreseen:

1 st] for cars with an open coachkork: compulsory fitting of aroll bar being .3 em higher than the driver's helmet andbeing wider than the driver's shoulders when seated at hiswheel;

2nd) for cars w th ;:J closed coachwork optional fitting in ofa roll cage improving the rigidity of the body and meantto prevent it from crushing in the event of a violent shockor a somersault. This roll-cage must be mounted, in sucha way that:

it shall in no way interfere with access to the seatsand normally occupying them;it shall not encroach on the volume reserved for thedriver or any of the passengers;the exact weight of the device. shall be subject to astatement from the competitor, to be appended to theentry form. This weight must be added to that indi-cated for the vehicle on the recognition form.

The fitting ot the above mentioned safety devices, which ismandatory for speed events (open cars), is authorized and evenrecommended for regularity trials.

-17-

n) Oil catch tank: when cars are running in events whioh. areonly speed races in closed circuits, they must be equipped in sucha way as to prevent oil from spilling on the track. In cars ofa cylinder-caoacity .nferior or equal to 2.000 cc, the oil catchingdevice shall have a minimum capacity of 2 litres and of 3 litresfor cars with a cylinder-capacity exceeding 2.000 cc, This provi-sion, mandatory for circuit speed events, will be optional for theother events (hill··climbs, rallies, even those including classificationtests run on closed tracks) unless required by the supplementaryregulations.

0) limits of authorized modifiçations: certain modifications tothe original parts, certain additions and/or removal of accessoriesnormal Iv mounted by the manufacturer of the model concerned,are explici+'v authorized by the or=sent regulations. The limitsof these modifications are set out for each of the 6 groups ofcategories A and B.. AII those not explicitly mentioned as permis-sible for the group in which the car claims classification andwhich affect, even secondarily, the mechanical efficiency of theengine, the steering, the transmission, the road-holding and/orthe braking, will imply the exclusion of the car from "its group.

If these modifications or additions have been the subject ofa previous statement by the entrant, the car may be allowedto compete in the event in one of the other groups providedin the supplementary regulations and with the prescriptions ofwhich it comolies. Should there be however an obvious case ofwillful misrepresentation, the entrant should not be authorizedto start or should be stoooed if he had alr e adv started, w:.threquest to the A.C.N. concerned to pronounce his suspensionfor at least 12 months.

p) Fuel: fuel shall be of commercial type generally distributedat road service stations of the country or countries ln which theevent is being run. If in one of the countries the standards ofthe best commercial fuel are inferior to the fuel having thelowest octane number in one of the three following countries:France, Great-Britain, Italy, a special waiver may be grantedto the promoters with the approval of the C.S.!.

Upper-cylinder or two-stroke engine lubricants are autho-rized on condition there is no increase of the fuel octane number.

Art. 254. - Rule for changing from one group to anotherand authorized amalgation of .groups:

Art. 255. - Definition : touring cars built on large seriesproduction terms. These cars shall compete in an event withouthaving undergone any preparation likely to improve their perfor-mances or their conditions of use. The only working authorizedis normal maintenance or the replacement parts damaged throughwear .or accident ant the modifications and additions explicitlyauthorized hereafter under article 257. Except for what is expli-citly authorized any part damaged through wear or accidentmay only be replaced by an :original part which must be exactlythe same as ·the one for which it is substituted,

Art. 256. - Minimum production and number of seats:series-production touring cars shall have been manufactured ina quantity of at least 5.000 identical units and offer at least4 seats, except if their engine cylinder-capacity is inferior orequal to 700 cc. In which case the manufacturer may deliverthem ·JS two-seaters.

Art. 257. - Mountings and modifications authorized:

a) lighting devices: all lighting and signalling devices mustcomply with legal requirements of the country of the event,

-19-

cars from abroad must comp.y in this respect with the Conventionon international road traffic.

Lighting devices which are part of the standard equipmentmust remain those foreseen by the manufacturer and must complyas far as is concerned their functioning with what the manu-facturer has foreseen for the considered model. Thus, if changingfrom a road beam to a passing beam is produced by merelydeflecting the beam inside one same reflector, this system maynot be altered.

Freedom is granted with regard to the frontal glass, thereflector and the bulbs.

It is permitted to add at the front only two lighting devicesin addition to those normally provided by the manufacturer andmentioned on the recognition form.

The mounting of reverse-lights is authorized provided policeregulations are respected but not the fitting of manœuvrablesearch-lights on the roof or elsewhere.

Waivers may be granted to these specifications on conditionthat they be explicitly provided for in the supplementary regula-tions of the event.

The mounting of additional headlights shall not entail anymodification of the coachwork.

The fitting of reverse-light is authorized, if necessary byembedding into the coachwork, but provided it will only switchon when engaging the reverse-gear.

b) Fuel and oil tanks: must be those normally provided bythe manufacturer for the model concerned, the capacities (Ifwhich are specified on the recognition form. If, for the samemodel, tanks of different capacities are normally provided, onlythose mounted on the required number of cars necessary forrecognition will be authorized.

The location and type of filling port for the fuel tank (s)may not be changed.

The use of a fuel tank with a larger capacity may beauthorized by the A.C.N. with the F.I.A.'s agreement, in thecase of events organized under particular climatic conditions (ondesert or tropical courses for instance).

c) Cooling circuit: if, for the same model, radiators ofdifferent capacities are normally provided, only those mountedon the required number of cars necessary for the recognitionwill be authorized. The addition of a radiator screen is authorized.

The use of a radiator with a larger capacity may be autho-rized by the A.C.N. with the F.I.A.'s agreement, in the case ofevents organized under particular climatic conditions (on desertCr tropical courses for instance).

Make and type of thermostat are free, but it may not beremoved nor its position changed.

d) Induction: the carburator(s) or fuel injector(s) pumpfs'normally mounted on the recognized model and described on therecogni rion form may not be changed or removed.

The elements which control the quantity of fuel fed in theengine may be changed, but not those which control the quantityof air.

e) Electrical equipment: the tension (voltage) of the elec-trical equipment may not be changed.

The make and capacity (amperage) of battery and generatorare free. The manufacturer may provide for one same minimumseries the use either of a dynamo or of an alternator on conditionthat this is explicitly mentioned on the basic recognition form oron an additional « variant» form.

The original battery may be replaced - by the manufactureror the entrant himself - by another one of larger capacityprovided however that the location remains unchanged. By locationof the battery is meant the coachwork compartment in wich thebattery is originally mounted.

Ignition coil, condenser, distributor and regulator are free;subject to the ignition system remaining the same as that providedby the manufacturer for the model concerned, and the repla-cement of the said accessories do not entail any modificationof the attachment system provided by the 'manufacturer for themodel concerned.

Spark plugs : make and type free.

f) Transmission : for one same series of 5.000 cars tnefollowing possibilities are given on the express condition thatthey are those of the series-production and that they are normallysold to the purchaser and entered on the recognition form,

Gear-box:

- 20- -21-

TITLE XI

SINGLE-SEATER RACING CARS

Art. 293. - Formula nO 1.Validity: from the 1st January 1966 to 31st December 1970.

Engines with alternating pistons:a) engine cylinder-capacity without supercharging:

or equal to 3.000 cc;

inferior

b) engine cylinder-capacity with supercharging: inferior orequal to 1 .500 cc.

-37-

Special engines:a) Rotary piston engines: cars with rotary piston engines

covered by the NSU-Wankel patents will be admittedon the basis of a piston displacement equivalence. Thisequivalence is twice the volume determined by the diffe-rence between the maximum and minimum capacity of theworking-chamber, thus a maximum capacity of 1.500 ccfor a non-supercharged NSU-Wankel type engine and amaximum capacity of 750 cc for a supercharged engine.

b) Turbine engines: cars propelled by a turbine engine willbe admitted on the basis of a formula of equivalencewith regard to alternating piston engines. This formula isthe following:

C X 0,09625A=-------

(3,10 X R) - 7,63A = High-pressure nozzle area-expressed in square centi-

metres by which is meant the area of the air-flow atthe exit from the stator blades (or at the exit fromthe first stage if the stator has several stages). Measu-rement is done by taking the minimum area betweenthe fixed blades of the high pressure turbine first stage.In cases where the first stage turbine stator blades areadjustable, they will open to their greatest extend 10present the greatest area for the determination ofarea « A ».

The area of the high pressure nozzle is thus theproduct - expressed in square centimetres - of heightby width and by the number of vane spaces.

C = Cylinder-capacity of the alternating piston engineexpressed in cubic centimetres (formula 1 : 3.000 cc).

R = The pressure ratio i.e. the ratio of the compressor ofthe turbine engine. This pressure ratio is obtained bymultiplying together a value for each stage of thecompressor, as indicated hereafter:Subsonic axial compressor = 1,15 per stage.Supersonic axial compressor = 1,5 per stage.Radial compressor = 4,25 per stage.Thus a compressor with one radial and six axial stageswill be designated to have a pressure ratio of:

-38-

4,25 xl, 15 x I ,15 X 1,15 X 1,15 x i.15 Xl, 15 or4,25 X 1,156•

c) The CS.I. reserve their right to modify the basis ofcomparison established between conventional type enginesand new type engines, while giving a previous notice ofone year to start from January I sr, following the dateon which the decision was made.

Minimum weight, without ballast (see hereafter) : 500 kilos.

Conditions imposed on F01mula 1 events:a) events counting for the World Championship must compul-

sorily be run on a distance of at least 300 km and at themost 400 km;

b) for other events, the promoters are free to fix the distancethey want in the supplementary regulations of their event,but should the provided distance exceed 400 km, theymust compulscrily provide at least one re-fuelling operation.

Art. 294. - Formula n'O 2.

Validity: from 1st January 1967 to 31 st December 1971.Alternating piston engines: engine cyl inde. -capacity superior

to 1.300 cc and inferior or equal to 1.600 cc.

Special engines: the same specifications as those providedhereabove for Formula 1 are valid for Formula 2, the differenceof cylinder-capacity being taken into account.

Minimum weight, without ballast (see hereafter): 420 kgs.

The cylinder-block must compulsority be taken from an F.I.A.recognized model of car, manufactured in a quantity of at least500 units in 12 consecutive months. The cylinder-capacity maybe obtained by increasing or reducing either the original bore crstroke or both dimensions.

On the cylinder-block, entirely finished will be permittedall modifications which are necessary to ensure the mountingand/or tightness of the cylinder-head, the driving device of thecamshaft(s), ignition distributor, pumps (water, fuel, injectionpump) and other accessories, when the original location or formof the above has been changed.

-39-

The type of cylinder (with or without sleeves) as well as thefriction system of connecting rod and crankshaft bearings mustremain the same as on the original engine.

The number of camshafts is free.

Feeding: the feeding system of the engine is free (by carbu-rettor, direct or indirect injection) but no device liable to havea supercharging effect may be mounted.

The number of cylinders per engine is limited at six, butthe CS.I. reserve their right to reconsider this decision fromthe moment that the F.I.A. would have recognized in one ofthe first three groups of Appendix « J », three models of carsof different makes with an engine of more than s'x ..vlindersand of a cylinder-capacity inferior or equal to 2.000 cc. Howevn-such a decision of modification would only come into effect asfrom the 1 st January of the following year.

Cooling system: the system of the original engine must bepreserved (by air, by water).

Propulsion: through a maximum of 2 wheels.

Cear-box: maximum 5 ratios, the reverse-gear not included.

Art. 295. Formula n'O 3.

Validity: from 1st [anuarv 1964 to 31 st December 1968.

Engine: alternating piston engines only. Max. cyl. capacity1.000 cc. Maximum cylinder-capacity may be obtained by increa-sing or reducing either the original bore or stroke or bothdimensions.

Maximum number of cylinders: 4.

The engine block, including cylinder-head and cylinders(should they be removable) shall be those of an F.I.A. reco-gnized model of car, manufactured in a quantity of at least1.000 units in 12 consecutive months, excluding all engineswith overhead camshafts.

The number of crankshaft bearings shall not be modified,nor the type of bearing (the replacement of a plain bearingby a roller bearing is therefore forbidden). The location of thecamshaft shall not be altered.

The induction system shall be the same as that used on the

-40-

car from which the engine has been taken (the use of an injectionsystem on an engine normally fed by a carburettor is thereforeforbidden) .

The engine shal] be equipped with only one carburettor,whatever its number of chokes, and a throttling flange of amaximum diameter of 36 mm and a minimum thickness of 3 mmshall compulsorily be mounted between carburettor and inletpipe. Through this throttling flange all the carburated mixturefeeding the cylinders must pass.

No supercharging device is authorized even if a series-pro-duction one was mounted on the original engine.

Other mec:hanic:al parts: the gear-box shall be that of anF.I.A. recognized model of car, manufactured in a quantity ofat least 1.000 units in 12 consecutive months, but not neces-sarily the one from which the engine has been taken. It shallnot have more than 4 forward ratios plus a reverse gear. Thescale of ratios is free. The use of any self-locking system on thedifferential is forbidden.

Dimensions: minimum wheelbase 200 cmminimum track I 10 cmmaximum width of coachwork 95 cm

Minimum weight, without ballast (see hereafter) : 400 kilos.Certificate of origin: any Formula 3 car showing up at the

start of an event shall be suopl ied with a certificate establishedby the manufacturer and ratified by the National SportingAuthority, specifying the origin of the basic elements of thevehicle.

Art. 296. _ Prescriptions and definitions applic:able to rac:ingcars of the 3 international formulae.

a) Minimum weight: the minimum weight is that of thecar in running order i.e. with all lubrication and cooling liquidsbut without fuel.

The ballast which is prohibited is that of a removable type.It is therefore permissable to complete the weight of the carthrough one or several ballasts incorporated to the materials ofthe car provided that solid and unitary blocks are used, andthat they are fixed by means of a tool and offer the opportunityof being sealed on should the officials entrusted with thescrutineering of the car deem it necessary.

-41-

b) The construction of the vehicle must be symetrical i.e.when the car is lifted laterally and weighed, the half weight oneither side must be equal to half the overall weight, a marginof + or - 5 % being allowed for the said half weight. Toverify the above, the weighing must be done with all tanksfull (fuel, water, oil) and a driver, weighing at least 75 kilosnormally sitting at the steering-wheel (or a ballast of the samewe'ght occupying the same piace).

c) Reverse-gear: all vehicles must have a gear-box includinga reverse-gear, which must be in working order when the. carst ar ts the events and able to be operated by the driver whennormally in his seat.

e) Protection against fire: besides that already provided byart. 125 of the International Sporting Code, the car shall beequipped with a general electric circuit-breaker either operatingautomatically or at the disposal of the driver.

f) Driver's seat liable to be occupied or left without itbeing necessary "to open a door or remove a panel. Sitting athis steering-wheel the driver must be facing the road.

g) Attachment points for safety-belt, the use of such a beltLeing optional.

h) Conlpulsory roll-bar complv'ng with the following condi-tions:

not overhanging the driver's head;exceeding in height by at least 3 cms the head of thedriver, wearing his helmet and normally sitting at hissteering-wheel ;exceeding in width the shoulders of the driver sittingat the steering-wheel;be strong enough to support at least the weight ofthe car plus that of the fuel .(tanks full) and the driver,without breaking nor deforming.

i) Wheels shall be external to the coachwork in such a wayi"hat no lateral elements of the coachwork (except for the allo-wance made for fuel tanks, as specified hereunder) may protrudebeyond the vertical plane tangent to the inner face of the wheels.

Should there be different tracks" the fore part of thecoachwork shall be limited by the vertical plane tangent to theinner face of the front wheels, and the rear part by the verticalplane tangent to the inner face of the rear wheels.

-42-

The mounting cf lateral fuel tanks is tolerated providedhowever they do not protrude beyond the vertical plane passingthrough the median line of the tires.

j) Braking safety system which must include a double circuitcperated by the same pedal and complying with the following:

the pedal shall normally control the four wheels;in case of a leakage at any point of the brake systempipes or of any kind of failure in the brake transmissionsystem. the pedal shall still control at least two wheels.

k) Fuel tanks complying with the following requirements:

the filling portis) and their caps shall not protrude beyondthe coachwork .naterial ;

the opening shall have a sufficient diameter for allowingthe air exhaust at the time of quick refuelling (in parti-cular those done under pressure) and if necessary thebreather-pipe connecting the tank with the atmosphereshall be such as to avoid any liquid leakage during therunning.

I) Oil catch tank: the mounting of a tank(s) or device meantfor collecting any oil spilling out of the engine and/or transmissionis compulsory. This device shall have a minimum capacity of3 litres for F 1 vehicles and those of tormula libre of a cylinder-capacity of more than 2.000 cc and a minimum capacity of2 litres for vehicles of Formula 2 and 3 and of formula libre ofa cylinder-c:aoacity inferior or equal to 2.000 cc.

m) Exhaust pipes: the outlet orifices of the exhaust pipes,when directed horizontally to the rear, must be placed at aheight of more than 30 em and less than 60 cm above theground. If they are not entirely covered by an element of thecoachwork, they may not protrude by more than 25 cm beyondthe overall length of the car.

n) No refuelling of lubricant is allowed for the wholeduration of the event.

The filling ports of the oil tanks and radiators shall providethe possibility of affixing seals.

The leads sealing the filling port(s) of the lubricant tank(s)may not be removed at any time during the race.

-43-

The leads sealing the filling port(s) of the radiator(s) shallbe in place at the start of the race, but may be removed at anypit-stop.

Art. 297. - Commercial fuel.a) Fuel for all piston engines (alternating and rotary): by

« commercial fuel» to be used in motor car speed events, theFederation Internationale de l'Automobile intends to designate a« motor» fuel produced by an Oil Company and currently distri-buted at road refuelling stations throughout one same country.

lVlav therefore be used, in all speed races for which theuse of commercial fuel is compulsory, all commercial fuels ofthe country in which the event takes place, with no other additiveExcept that of a lubricant of current sale which cannot increasethe octane number, or water.

May also be used, under the same conditions, any commercialfuel(s) which - in France, Germany, Great Britain and Italy -IS (are) of the highest octane rating, according to the ResearchMethod.

If the above-mentioned fuel could not be easily importedinto the country where the event is taking place, it may bereplaced by another one of similar quality and with the sameoctane-number (RM) - with a tolerance of + J - speciallymade by an Oil Company.

Whene,.,er - in France, Great Britain, Germany and Italy -a new commercial fuel is made available which has a higheroctane-rating than those sold so far, the Oil Company producingthis said fuel shall give notice to the F.I.A. by a registeredletter and this new commercial fuel (or its equivalent as speci-fied hereabove) may be used for racing 30 days after' theregistered letter has been mailed.

The Oil Companies who supply fuel directly to the entrantsof a race shall have to send to the promoters the characteristicsand a sample of the fuel delivered in such quantity as issufficient to carry out the necessary analyses, and also adeclaration stating that the fuel complies with the presentspecifications.

b) Fuel for vehicles propelled by turbine engines: keroseneused by commercial aviation companies for turbo-prop or jetengines or the fuel used by vehicles with conventional typeengines and complying with the here-above definition of« commercial fuel». .,

Art. 298. - Formula « libre'».It is permitted to organize sporting competitions open 1'0

other racing cars than those defined by one of the 3 Internationa!

Formulae.All specifications concerning the vehicles and particularly

the limitations of the cylinder-capacity are in this case at thediscretion of the promoters and it rests with them to list thesespecifications as clearly as pOSSible in the Supplementary Regu-lations of the event, which anyway have to be approved by theNational Sporting Authority answerable to the F.I.A.

However racing cars which do not comply with any of theInternational Racing Formulae, must for security reasons be inconformity with the following rules listed here-above underArt, 296, General prescriptions and definitions: e), h), i), k),

I), m), n).
