This dimension shall be measured at the immediate rear of the steering wheel, perpendicular to the longitudinal axis of the car. It must be maintained on a minimum height of 25 cm.
The passengers place shall remain available during the whole of the event. It shall not be either partly or totally covered and shall offer the same conditions of comfort, room and protection as that of the driver’s. However the passenger’s place may be sheltered by means of a cloth or any similar supple material liable to be quickly removed by hand without using any tools. Under no condition may the seats serve as a holder to a spare wheel or be combined with the fuel tank(s). Tanks shall be placed outside the cabin so as to protect the passengers of the car from any fumes or dhect splashing of the fuel.
The transmission organs (shafts and cardan joints) must be under the floor boards or be fitted in tubes or casings. The floor boards, tubes or casings must not be of a temporary nature but mist be properly joined together and fhmly fixed to the coachwork and the chassis.
Front seats must fulfill the conditions setout hereafter (Figure 1 and 2).
a is always measured horizontally and parallel to the longitudinal axis of the chassis, between two vertical planes perpendicular to the longitudinal axis and limiting from front to rcar the open space on a level where the measurement taken.
For the driver’s seat, a is measured on the floor level, or at the bottom of any recess if need be, from the perpendicular at the furthest pedal in its position of rest.
For the passenger seat. this measurement is taken at a height of 20 cen theters above the floor, or at the bottom of the recesses, if need be.
In case of movable seats it is forbidden to alter the position of any seat while the cars are being measured.
b is measured vertically from the rear of a to the horizontal plane tangent to the highest part of the cushion as shown on the drawings.

Height:
--15 cm (5.9 in.) measured vertically all along the minimum width.
It shall be efficiently attached to the hood or to the roof of the car, if of closed body type.
If the windscreen is equipped with glass, only glass of safety type shall be permitted.
The windscreen must have at least one automatic wiper, placed in front of the driver, the surface action of the wiper should be sufficient for the driver to be able to see the road distinctly, from his seat.
209. Mudguards
Mudguards of vehicles must not include temporary parts and they must be firmly affixed.
They must he placed exactly above the wheels and they must cover the effectively by surrounding at least a third of the circumference. It will, however, be permitted to make in each mudguard an opening not exceeding a maximum of 200 square cen thetres (31 in2) to enable the driver to check the condition of his tires.
The width of mudguards must be such as to cover the tires completely when the wheels are parallel to the longitudinal axis of the car. In those cars where the mudguards are entirely or partly overhung by the structure of the body, the combination of mudguards and body, or the body alone, must nevertheless fulfill the above-mentioned requirements as to protection.
The rear extremeties of the front and rear mudguards must not be higher above the ground than a horizontal line passing through the center of the wheel hub cap.
Mudguards fitted on the wheels and liable to turn when the wheels are steered are prohibited. They must therefore be solid with the body, there being no gap between them.
210. Hoods (Tops)—No longer required on open sports-racing cars in 1962.
211. Closed cars
Bodies of closed cars, convertible or not, must correspond at least to all the conditions indicated above for open cars.
Bodies of closed cars must he established in such a way that they ensure perfect visibility for the driver. The windows must he fitted with safety glass.

All the wheels of the car shall have the same diameter.
All through the competition, at least one spare wheel, with tyre, identical to one of those mounted on the car must be placed outside the space reserved for occupants of the vehicle, and in such a manner that the normal working of thc door is not impeded. Extra spare wheels may, if necessary, be placed in the rear seats of cars for more than two passengers, but in no case may they occupy the space reserved for passengers in the front seat(s).
During competitions, and for safety reasons, spare wheels placed outside the bodies must comprise at least two kinds of systems to fix them, which must be independent one from the other (for instance a hub shaped attachment and straps).
Dimensions of tyres are free.
214. Rear-reflecting mirrors—Silencer—Lighting and Warning apparatus
Vehicles must compulsorily be fitted with:
- A rear-reflecting mirror with a reflecting surface of at least 50 cm2 (7.75 in.2)

The exhaust pipes shall be arranged so as not to raise any dust.
The sound and luminous signaling devices shall be in working order from beginning to end of the competition.
The lighting devices shall comply with the provisions of the International Convention on Motor Traffic. They shall furthermore be in working order at the start of the competition and remain so during the normal hours of functioning as well as during the hours which are foreseen in the Supplementary Regulations.
The Supplementary Regulations shall lay down what penalties apply in case of tile above accessories being broken, lost, rendered partly or completely useless.
However, damage done to glass by projection of stones shall not be subject to penalization and the replacement of burnt out electric bulbs shall always be authorized.
215. Special provisions
All the integral parts of the body, such as front and rear mudguards, supports and frame of windscreen, hoods, doors, spare-wheel attachments, must be maintained in normal position of use until the end of the event (or if need be, replaced at the first passage at a replenishment pit).
Any competing car shall be in strict compliance with the traffic regulations of either its country of origin, or its country of registration.
Furthermore, the Supplementary Regulations may provide that only those cars are eligible which carry a national registration plate enabling proper identification, to the exclusion of all provisional mobile plates (trial or garage keeper’s plate).
All vehicles corresponding to the above characteristics must be admitted in all International Competitions for Sports cars. But this obligation shall not prevent promoters from refusing entry to a competitor, on account of any other reason.
TO THE INTERNATIONAL SPORTING CODE GENERAL REGULATIONS
FOR TOURING AND GRAND TOURING CARS
(1962)
CHAPTER I—GENERAL PROVISIONS
251. Enforcement of the Regulations
The present regulations define all cars built in large or small series and recognized by the FIA in categories "TOURING" or "GRAND TOURING" in compliance with provisions of article 254 below.
They compulsorily apply to all events entered on the International Sporting Calendar (speed events or regularity trials) or on the Calendar of National Events with foreign participation authorized and in which series production cars of the Touring and Grand Touring categories participate.
252. Categories and groups of vehicles
Vehicles referred to in the above article shall be distributed into the following categories and groups:
A. "TOURING" category:
Group 1. Series production Touring Cars
Group 2. Improved Touring Cars
B. "GRAND TOURING" category:
Group 3. Grand Touring Cars
This group takes in also series production Touring Cars with altered bodies as well as Touring Cars belonging to the former group of "Special Touring Cars".
Events open to cars of the Touring and/or Grand Touring categories may also be open to cars of the "Sports" category. In that case cams of this category, which is not defined in the present regulations, shall form the:
C. Group 4. Sports Cars
In which shall be admitted all cars complying with the special regulations of Appendix C to the International Sporting Code, as well as Touring and Grand Touring Cars of a model recognized by the FIA, but which because of changes effected cannot be entered in one of the 3 above mentioned groups (see art. 274 hereafter).
Promoters are free to choose the group(s) they wish to include in the Supplementary Regulations.
Except when otherwise specified by the FIA for a given category of events, the combination of several consecutive groups is authorized.
Since the order of groups as given here-above is considered as forming a logical progression, a car which is eligible for competing in any group not provided in the Supplementary Regulations of an event is automatically eligible for competing in a higher group.
253. Class Scale
Cars shall be distributed into the following 15 classes, according to the engine cylinder capacity:
1. Cars with an engine capacity inferior or equal to 400 cc
2. Cars with an engine capacity exceeding 400 cc and inferior or equal to 500 cc
3. Cars with an engine capacity exceeding 500 cc and inferior or equal to 600 cc
4. Cars with an engine capacity exceeding 600 cc and inferior or equal to 700 cc
5. Cars with an engine capacity exceeding 700 cc and inferior or equal to 850 cc
6. Cars with an engine capacity exceeding 850 cc and inferior or equal to 1000 cc
7. Care with an engine capacity exceeding 1000 cc and inferior or equal to 1150 cc
8. Cars with an engine capacity exceeding 1150 cc and inferior or equal to 1300 cc
9. Cars with an engine capacity exceeding 1300 cc and inferior or equal to 1600 cc
10. Cars with an engine capacity exceeding 1600 cc dud inferior or equal to 2000 cc
11. Cars with an engine capacity exceeding 2000 cc and inferior or equal to 2500 cc
12. Cars with an engine capacity exceeding 2500 cc and inferior or equal to 3000 cc
13. Cars with an engine capacity exceeding 3000 cc and inferior or equal to 4000 cc
14. Cars with an engine capacity exceeding 4000 cc and inferior or equal to 5000 cc
15. Cars with an engine capacity above 5000 cc
The above classification applies to cars with non-supercharged engines.
Cars equipped with a supercharging device provided for the whole series by the manufacturer may be recognized by the FIA but in one of the classes above the one they would belong to according their normal cylinder capacity.
Except when otherwise occasionally specified by the FIA for a given category of events, there is no obligation for the promoters to include all the above classes in the Supplementary Regulations and furthermore, they remain free to combine two or more consecutive classes according to circumstances particular to their events.
254. Recognition of series production models
Before a series production car is accepted in the "TOURING" or "GRAND TOURING" category in a competition, it has to be recognized in that category by the FIA.
Recognition of each Touring or Grand Touring model shall be requested by the National Automobile Club (ACN) of its manufacturing country. Said request shall be accompanied with a certification from the ACN that the minimum production required has been met and within a recognition form (see art. 255) enabling the unmistakable identification of the model concerned
Recognitions will be granted by the FIA, on recommendations of a Sub-Commission appointed by the CSI called "Sub-Commission for Recognitions". They will he circulated at the earliest opportunity by the FIA Secretariat.
Any change definitely brought to the series production of an existing model shall make the subject of a descriptive note giving specifications as to the exact nature of the change effected. Said note shall be established by the ACN of the country where the altered vehicle has been manufactured, and submitted by the ACN to the Sub-Commission for Recognitions.
The Sub-Commission will have to determine which of the following case is concerned:
lST CASE: INTRODUCTION OF A NEW MODEL
The change(s) introduced for good either noticeably improve the performance of the vehicle, or modify its main characteristics.
It shall be then considered as a new model for which construction of the minimum series in the category concerned shall be required, and a new recognition form shall have to be issued.
2ND CASE: NORMAL EVOLUTLON OF THE TYPE
The change(s) introduced for good (construction of previous model abandoned) do not noticeably improve the performance or the main characteristics of the vehicle.
The altered model will remain covered by the original recognition without the manufacturer being required to produce a new minimum series, but the changes must be stated either on a supplementary form appended to the existing one or on a new recognition form.
In particular, such is the case of models on which a change of cylinder-capacity has been carried out, as exceptionally authorized during the years 1960-1963, to enable the readjustment of models to the new limits of classes provided by art. 253 and subject to the following conditions:
- The production of engines of the previous cylinder-capacity must be definitely discontinued.
- The cylinder-capacity may be increased till the superior limit of the new class, or reduced under the superior limit of the preceding class.
- The change may be obtained by modifying either the boring, or the stroke, or by both said means, provided that apart from the pistons, sleeves, connecting rods and crankshaft, all the mechanical parts of the engine unit including their location are not modified.
The model may otherwise not be subject to any modification whatsoever not explicitly permissible according to the present regulations.
3RD CASE: VARIANT
One or several changes are made and noticeably modify either the performance or the main characteristics of the vehicle, but these changes concern only a part of the production of the manufacturer and the construction of the previous model is not discontinued. Said changes will be considered as introducing a "variant" which shall be accepted as well as the original model as soon as the minimum series required for this category of car has been built in twelve months. The variant will imply the drawing up, either of a new recognition form or of an additional one to be appended to the already existing recognition form.
However, when the changes imply a noticeable reduction of the performances, such as those which are necessary for adapting a car to utility tasks to the detriment of the mechanical efficiency, the variant (s) will be accepted without imposing upon the manufacturer the obligation of previously producing a minimum series, subject to the following conditions:
- That all the parts liable of being substituted be mentioned on the recognition form concerning said model.
- That the substitution although it reduces the general efficiency does not improve certain secondary performances which are of special interest in, the competition in which the vehicle has been entered (for instance the fitting of a carburetor of economy type for a fuel consumption event).
The variant(s) may however always be accepted without having to give evidence of a minimum series production, when it concerns (or they concern) a special equipment for climatic or other purposes intended to adapt the car to an arctic or tropical climate or to an unusual type of ground (such as desert or bush) under the express condition that the vehicle is only used in competitions run in the particular circumstances which are referred to hereabove.
255. Recognition Forms
All Touring and Grand Touring cars recognized by the FIA will be described on a form, called Recognition Form, drawn up by the National Automobile Club, on which will he entered the chief specifications enabling the identification of each model.
Shall only he used to this effect by all ACN’s the model recognition form, as well as the additional form for "normal evolution of the type" and "variant", drawn up by the FIA.
These forms will be prepared by the ACN of the country in which the car has been built and submitted by said ACN to the Sub-Commission for Recognitions.
It rests within the entrant to secure the recognition form and if need be the additional form concerning his car either from his ACN or if not available at his own ACN, from the ACN of the country in which his vehicle has been built.
Promoters may require entrants to produce the form at scrutheering and/or at the start. They will be entitled to refuse participation of an entrant if the necessary form(s) is (are) not produced.
256. Fuel
Fuel shall be of a commercial type generally distributed at road service stations of the country or countries in which the event is to be run. If in one of the countries, the standards of the best commercial fuel is inferior to the fuel having the largest octane number is one of the three following countries: France, Great Britain, Italy, a special waiver may be granted to the promoters with the approval of the CSI. Upper cylinder or two stroke engine lubricants are authorized, on condition there is no increase of the fuel octane number.

FOR TOURING AND GRAND TOURING CARS
(1962)
CHAPTER II—GROUP 1—SERIES PRODUCTION TOURING CARS
257. Definition--Minimum of construction
Series production Touring cars are motor vehicles intended for the transportation of persons and for which the manufacturer has endeavoured to obtain the best performance in normal conditions of use. They must be recognized by the FIA in the "Touring" category.
In order to enjoy such recognition, these cars must be in conformity with a model well defined in a catalogue and obviously intended for normal use, for pleasure or business. They must he offered to customers by the regular sales department of their manufacturer.
They must be of a model in current production or which has not heen definitively abandoned for over 4 years. They must have been manufactured in series at a minimum rate of 1000 units in 12 consecutive months and he identical as far as mechanism and coachwork are concerned.
By identical is meant that the external shape and the component materials of the mechanical parts, the chassis and the body must remain unchanged.
To the exception of the modifications and additions explicitly authorized according to the present regulations, any accessory and/or any mechanical part may only be replaced by the same accessory or the same part used by the manufacturer for the considered model, the only tolerances in size being those officially provided by the factory.
All elements of the vehicle must compulsorily he those of one same recognized model, whether said model is the basic one or one of its variants also recognized (see art. 254) to the exception of elements whereof the addition, the removal or the replacement is explicitly authorized according to the present regulations (considering the group which applies).
However, in case of "normal evolution of the type" (see above art. 254, 2nd case) when a manufacturer has abandoned for good the production of certain spare parts, spare parts of the altered model may be substituted, provided they are perfectly adaptable and do not imply any modification whatsoever of the supports.
258. Coachwork
Series production touring cars shall have a closed body or a "convertible" body.
Coachwork means all the external parts of the vehicle licked by the air streams and located above a plane passing through the wheel hubs.
Convertible coachwork means a body which can be either completely closed, or open, with inter aliis mobile windows in the doors. Is excluded all coachwork fitted with a simple hood offering but a scanty protection against bad weather, even if the hood is equipped with detachable sidescreens.
As a rule the body shall be built by the manufacturer of the frame. However, a series production body manufactured by a coachwork builder approved by the maker of the frame may be admitted. For cars whose body has been made outside of the main factory, there will have to he at least 1000 units assembled within a period of 12 consecutive months and said cars will be subject to a separate recognition.
259. Number and dimensions of seats
Series production Touring cars shall have the number of seats provided by the manufacturer. This number shall be at least TWO when the engine cylinder capacity is inferior or equal to 1000 cc and at least FOUR when the engine capacity is superior to 1000 cc.
Shall be counted as seats only those especially adjusted by the maker of the body for the sake of carrying the passengers, drivers included.
The seats shall have the following minimum dimensions as indicated on the sketch below:
a is always measured horizontally and parallel to the longitudinal axis of the chassis, between two vertical planes perpendicular to the longitudinal axis and limiting from front to rear the open space on a level with the height where such measurement is taken.
For the driver seat a is measured at floor level, or at the bottom of any recess, from the perpendicular of the nearest pedal at rest.
For the passenger seat a is measured 20 cm above floor level or the bottom of recesses if need be.
In the case of movable seats the position shall not be altered when measurements are taken.
b is measured vertically from the rear of a to the horizontal plane tangent to the highest part of the cushion, r; shown on the sketch.
c is measured in the horizontal plane defined above from the upper and of b, parallel to a and in the center of each seat, as far as the vertical plane perpendicular to the longitudinal axis of the chassis and tangent to the foremost point of the back of the seat.
Back of seats shall have a mininimum height of 30 cm, measured vertically from the rear end of c.
The coachwork must be planned in order to obtain:
a + b + c 1,10 m. minimum
The minimum width for foot space (for each person) shall be 25 cm measured perpendicularly to the longitudinal axis of the chassis, at the vertical of the pedals.
Shall not be considered as a four-seater, cars offering inside the coachwork for 2 normal seats and a back space provided for the transportation of dogs or luggage, even if the dimensions of said space enable the temporary accommodation of passengers.
The normal arrangement of the seats may be subject to all kinds of modifications intended to improve the comfort of the occupants of the car (transformations of the seats or their replacement by others) subject to there being no reduction of the number or of the comfort of the seats provided by the manufacturer.
260. Minimum weight
The recognition form shall state the official weight of the considered model. This weight shall be obtained by taking the average of the actual weighing of five closed cars of the same model, selected at random and weighed in the following conditions: with the spare wheel provided by the manufacturer and with a tyre which is the same as those which are mounted on at least two wheels of the vehicle, with full oil tank, and full water tank (if such is the case) but without fuel, tools, luggage or anyone aboard.
When the weight is being checked by the scrutineers on the on the occasion of an event, a tolerance of minus 5% as compared with the weight entered on the recognition form will he granted, whatever the cause of the reduced weight and provided it results from a lightening which is permissible according to the present regulations.

CHAPTER IV— GROUP 3—GRAND TOURING CARS
264. Definition
Grand Touring Cars are vehicles built in small series for customers who are hooking for a better performance and/or a maximum comfort and are not particularly concerned about economy.
Such cars shall conform to a model defined in a catalogue and be offered to the customers by the regular sales department of the manufacturer. They must be recognized by the FIA according to the provisions of article 265 below.
Shall on the other hand also be classed in group 3 (Grand Touring Cars) Touring Cars recognized in the Touring category, made of series production mechanical parts and not having been subject to any other changes or additions apart from those authorized according to art. 261 and 263 but equipped with a special coachwork.
By special coachwork is meant:
In that case, two possibilities are to be examined:
- If the frame is of self-bearing type, it shall be maintained and may be strengthened, but not lightened nor cut.
- If the frame is not of self-bearing type, that is when the car has no frame or only a partial or insufficiently bearing one, the body may be changed as a whole, but shall under its new shape compulsorily use the original attachment points on the series production elements of the suspension, propulsion and steering.
Shall also be classified in the same group 3, Touring Cars equipped with their standard coachwork, but having been subject to changes or additions not authorized by art. 261 and 263 above and whose limits are stated hereafter under art. 274, b.
265. Minimum production--Recognition
In order to enjoy recognition in the "Grand Touring" category, cars will have to be produced at a minimum rate of one hundred identical units as far as mechanical parts and coachwork are concerned in 12 consecutive months.
The word "identical" has the same meaning as defined under art. 257, 4th paragraph. However, one same minimum series of 100 units may have two different carburetor equipments either in number or size.
By "equipment" is meant the carburetor and venturi unit.
Moreover cars will have to conform to specifications of articles 266-270 below.
266. Ground Clearance
All parts of the chassis shall be at least 12 cm from the ground, so that a mass of 80 cm wide and 12 cm high may be introduced between the rear wheels of the car and slipped through the whole length of the car.
This ground clearance may be measured with empty tank and with nobody in the car, which must be equipped with the wheels and tires that are to be used in competition.
267. Lock
The maximum lock shall he 6.75 m. which means that the car must be able to make a complete turn in any direction without the wheels going beyond two parallel lines 13.50 m apart, drawn on the ground.
268. Starting
Grand Touring cars shall have to be equipped with a starting device liable of being operated by the driver when aboard.
269. Fuel tank

NB. Any alteration or addition not explicitly authorized hereabove will make the vehicle uneligible in group 3 and will entail its assignment to group 4 (see art. 275 hereafter).
Any change or addition not listed above and which has not been subject to a previous written statement of the entrant will entail a penalty which may go as far as exclusion from the competition without prejudice to higher penalties in case of willful misrepresentation.
271. Touring cars assimilated to "Grand Touring"
a. TOURING CARS WITH SPECIAL COACHWORK
Touring cars of a model recognized by the FIA equipped with special coachwork, as defined in art. 270 aabove but in conformity with regard to mechanism with the series production model, except for changes and additions authorized according to art. 261 and 263, shall be assimilated to Grand Touring cars and may participate in events in group 3.
If the above cars are subject to changes and additions exceeding the limits provided under 261 and 263, they will be authorized to enter the events only in group 4 - sports car (see art. 275 below).
b. TOURING CARS WITH STANDARD COACHWORK AND SPECIAL MECHANICAL PARTS
(PREVIOUSLY CALLED SPECIAL TOURING CARS)
Shall also be assimilated to Grand Touring cars, Touring cars of an FIA recognized model equipped with their original coachwork but which have been subject to alterations and additions other than those authorized according to art. 261 and 263, and made either by the manufacturer or he competitor, with the intention of increasing the performances and improving the conditions of use of the vehicle.
These alterations or additions may affect the mechanical parts of the engine, of the transmission, of the steering, of the suspension, the number of carburetors, the inlet and exhaust system, the braking system
The re-boring of the engine whether sleeveless on fitted with sleeves, is authorized up to the limit of the class to which belongs the car according to its original cylinder capacity. Furthermore, in consideration of the trend of technical evolution, and the necessity of increasing the safety of cars whose high performances had not been initially foreseen by the manufacturer, the improvement of the braking may be seeked without any obligation of maintaining the original system. Drum brakes may therefore be replaced by disk brakes.
However, the fundamentals and general design of the car, of the engine and other mechanical parts must remain the same as those of the corresponding series production car. The standard coachwork must not he modified, the chassis may be reinforced but not lightened nor cut The track and wheel-base mast remain unchanged. The suspension and rear axle must remain of same type. All casings and blocks housing the mechanical parts must remain unchanged, except for the following:
- Cylinder-head
- Oil sump
- Braking system
- Gear box and rear axle box, which may be subject to minor alterations to enable the modification of the gear box ratios or the mounting of an overdrive.
The minimum weight must be that entered on the recognition form of the corresponding series production touring car, but the tolerance granted when the weight is checked will be minus 10% (instead of minus 5%).
The addition of compressors, blowers or any kind of supercharging device not provided for the series production and not entered on the recognition form remains prohibited on cars of this group.
All changes or additions not authorized under art. 261 and 263 shall be the subject of a written statement from the competitor to be appended to the entry form sent to the promoters.
NB. Any omission or wrong information on the above mentioned statement will entail a sanction which may go as far as excluding the car from the competition without prejudice to higher penalties in case of willful misrepresentation.
