II ELIGIBILITY OF VEHICLES AND EQUIPMENT
A. Application
1. These regulations shall apply to
vehicles competing in rallies which contain special stages.
2. Vehicles must comply with these
regulations at all times during the competition.
B. Definitions
All vehicles belonging to a production
series, distinguishable by a specific conception and general exterior lines
of the coachwork and by an identical method of transmitting the engine
power to the drive wheels.
Turbocharged or supercharged vehicles
will be considered as different models than normally aspirated versions
of the same car.
A model may exist in several variants
as to coachwork (i.e.: 2 door sedan, 4 door sedan, coupe, station wagon
etc.) or with regard to mechanical components.
Original equipment or original shall
mean all components of a vehicle which are offered and installed as standard
or optional equipment for a coachwork variant of a model by the manufacturer
through normal marketing channels in Canada or,
for Group N, as provided for in the homologation papers for the vehicle.
C. Safety Regulations
All competing vehicles must be roadworthy
and, the following items in particular must be adequate and functioning
properly:
(d) All legally required exterior
lights.
(e) Tires, including all spares.
(a) Rollcages are mandatory for all
vehicles.
(b) Specific roll over protection
is subject to the approval of the scrutineer at each event.
(c) Basic design considerations.
The essential features of safety cages
are sound construction designed to suit the particular vehicle, adequate
mountings and a close fit to the bodyshell.
(i) The basic purpose of the roll
over protection is to prevent serious bodyshell deformation, and so reduce
the risk of injury to occupants, in the case of a collision or of a car
turning over. The safety cage must not unduly impede the entry or exit
of the driver and co-driver.
(ii) The rollcage is a structural
framework made up of a main rollbar and a front rollbar (or a main rollbar
and two lateral rollbars), their connecting members, one diagonal member,
backstays and mounting points. (For example, see drawings
253-3 and 253-4). Longitudinally, the safety cage must be entirely contained
between the top mounting points of the front suspension and the top mounting
points of the rear suspension.
Structure consisting of a near-vertical
frame or hoop located across the vehicle just behind the front seats.
Similar to main rollbar but its shape
follows the windscreen pillars and top screen edge.
Similar to main rollbar but its shape
follows the outline of the door from the top of the main rollbar, along
the roof and the windscreen pillar to the floor. The front leg must be
against the windscreen pillar and the door pillar such that it does not
unduly impede the entry or exit of driver and co-driver.
Longitudinal tube which is not a part
of the main, front or lateral rollbar but which links them.
Transverse tube between a top corner
of the main rollbar or upper end of a backstay and a lower mounting point
on the other side of the rollbar or backstay.
f) Framework reinforcement:
Reinforcing member fixed to the rollcage
to improve its structural efficiency.
Metal plate fixed to the bodyshell
or chassis structure under a rollbar mounting foot to spread load into
the structure.
Plate welded to a rollbar tube to
permit its bolting or welding to the bodyshell or chassis structure, usually
onto a reinforcement plate.
Structural members of a safety cage
which are able to be removed.
A bracing member which connects the
top of the main hoop to the body of the car behind the main hoop.
Only rollcages must be used.
a) Compulsory diagonal member:
Different ways of fitting the compulsory
diagonal member: (see drawings 253-3 to
253-5.)
The combination of several members
is permitted.
b) Optional reinforcing members:
Each type of reinforcement (drawings
253-6 to 253-17, 253-17A and 253-17C) may be used separately or combined
with others.
Longitudinal rollcage extensions are
allowed up to the level of the original suspension mounting points on the
shell. There must not be direct connection between the top extension and
the bottom extension.
(iv) Main, front and lateral rollbars:
These frames or hoops must be made
in one piece without joints. Their construction must be smooth and even,
without ripples or cracks. The vertical part of the main rollbar must be
as straight as possible and as close as possible to the interior contour
of the bodyshell.
The front leg of a front rollbar or
of a lateral rollbar must be straight, or if it is not possible, must follow
the windscreen pillars and have only one bend with its lower vertical part.
Where a main rollbar forms the rear legs of a lateral rollbar (drawing
253-4), the connection to the lateral rollbar must be at roof level.
One continuous length of tubing must
be used for each of the hoops with smooth continuous bends and no evidence
of crimping or wall failure.
The tubing must be bent by a cold
working process and the centreline bend radius must be at least 3 times
the tube diameter. If the tubing is ovalised during bending, the ratio
of minor to major diameter must be 0.9 or greater.
To achieve an efficient mounting to
the bodyshell, the original interior trim may be modified around the safety
cages and their mountings by cutting it away or by distorting it.
However, this modification does not
permit the removal of complete parts of upholstery or trim unless permitted
elsewhere in these regulations.
Where the occupants' bodies or their
crash helmets could come into contact with the safety cage, non-flammable
padding must be provided for protection.
(vi) Doorbars (for side protection):
These are compulsory and must be attached
near the roof line and near the top outer bends of the main rollbar on
both sides of the car. They must make an angle of at least 30° with
the vertical, must run rearwards and be straight and as close as possible
to the interior side panels of the bodyshell.
Their materials specification, diameter
and thickness must be as defined in 2.d.
Their mountings must be reinforced
by plates. Each backstay should be secured by bolts having a cumulative
section area at least two thirds of that recommended for each rollbar leg
mounting in 2.e, and with identical reinforcement plates of at least 60
cm2 area (see drawing 253-25).
A single bolt in double shear is permitted,
provided it is of adequate section and strength (see drawing
253-26) and provided that a sleeve is welded into the backstay.
At least one diagonal member must
be fitted.
Drawings
253-3 to 253-5 are examples of diagonal members and they must be straight,
not curved.
The combination
of several members is permitted according to drawings
253-3 and 253-5. The fitting of a second diagonal member, according to
drawing
253-4, is
recommended
in 2001 and mandatory for all cars with a log book issued after January
1, 2002. The connection between the two members must be reinforced by a
gusset.
The attachment points of the diagonal
members must be so located that they cannot cause injuries. They may be
made removable but must be in place during events. The lower end of the
diagonal must join the main rollbar or backstay not further than 100 mm
from the mounting foot. The upper end must join the main rollbar not further
than 100 mm from the junction of the backstay joint, or the backstay not
more than 100 mm from its junction with the main rollbar.
They must comply with the minimum
specification set out in 2.d. Diagonal members fixed to the bodyshell must
have reinforcement plates as defined in 2.e.
(i) For
events in Highly recommended for
all events and vehicle classes, but required for all FIA
sanctioned championship
events and Group N vehicles: cold drawn
seamless finished
unalloyed carbon steel containing a maximum of 0.22%0.3%
of carbon and having a minimum tensile strength of 350N/mm2.
The
maximum content
of additives
is 1% for manganese and 0.5% for other elements.
The size of tubing to be used shall
be as follows:
| Dimensions
(mm) |
Use |
45 x 2.5 (1.75" x 0.1")
or 50 x 2.0 |
Main rollbar (drawing
253-38) and lateral rollbar and or their connections
(drawing 253-39) according to construction. |
38 x 2.5 (1.5" x 0.1")
or 40 x 2.0 |
Other parts of the safety
cage. |
(ii) For all other
CARS vehicle classes and all other events, safety cages may
use Seamless, ERW or DOM mild steel tubing.
The size of tubing to be used shall be as follows:
| Dimensions (mm) |
Use |
| 44 x 3.0 (1.75" x 0.12") |
All parts of the safety cage |
| |
(iii) Note that these figures represent
the minima allowed. In selecting the steel, attention must be paid to obtaining
good elongation properties and adequate weld ability.
An inspection hole of at least 4.5
mm diameter must be drilled in a non-critical area of the main hoop to
facilitate verification of wall thickness.
(iv) Where nuts and bolts are used,
they must be of at least M8 size of ISO standard 8.8 or better.
Fasteners must be self-locking or
fitted with lock washers.
(e) Mounting of rollcages to the bodyshell:
- 1 for each leg of the main or lateral
rollbar ;
- 1 for each of the front rollbar
;
Each mounting foot of the front, main
and lateral rollbars must include a reinforcement plate, of a thickness
of at least 3 mm which must not be less than that of the tube onto which
it is welded.
Each mounting foot must be attached
by at least three bolts on a steel reinforcement plate at least 3 mm thick
and of at least 120 cm2 area which is welded to the bodyshell. Examples
are shown in drawings 253-18 to 253-24.
This does not necessarily apply to backstays (see 2.c.vii).
These are minimum requirements. In
addition to these requirements, more fasteners may be used, the rollbar
legs may be welded to reinforcement plates, the rollcage may be welded
to the bodyshell. Rollbar mounting feet must not be welded directly to
the bodyshell without a reinforcement plate.
(f) Required Reinforcement
Gussets or corner braces joining the
front continuous tubing, whether front rollbar or lateral rollbar, and
the brace tubing are required. The gusset or brace shall span the weld
that joins the two tubes and may be positioned either in the roof quadrangle
or in the windshield area.
If gussets are used they must be of
a thickness equal to the wall thickness of the roll cage tubing and must
be a minimum of 5 cm long where they contact the roll cage tubing. They
must be welded along this entire length and relieved in the corners so
as to not interfere with existing welds.
If reinforcing tubes are used they
must span at least 13 cm across the corner at its longest point but must
not be more than half way down or along the members to which they are attached,
except for those of the junction of the front rollbar, which may join the
junction of the door strut/front rollbar.
(g) Optional Reinforcement
The diameter, thickness and material
of reinforcements shall be as defined in 2.d.
(i) Rollcage reinforcement:
It is permitted to reinforce the junction
of the main rollbar or the front rollbar with the longitudinal struts (drawings
253-10 and 253-16), as well as the top rear bends of the lateral rollbars
and the junction between the main rollbar and the backstays.
A reinforcement as in drawing
253-17B may be added on each side of the front rollbar between the upper
corner of the windscreen and the base of this rollbar.
Reinforcing the upper part of the
rollcage by adding members as shown in drawings
253-9 and 253-9A is permitted.
(iii) Transverse reinforcing members:
The fitting of two transverse members
as shown in drawing 253-7 is permitted.
The transverse member fixed to the front rollbar must not encroach upon
the space reserved for the occupants. It must be placed as high as possible
but its lower edge must not be higher than the top of the dashboard.
Should removable members be used in
the construction of a rollcage, the demountable joints used must comply
with a type approved by the FIA (see drawings
253-27 to 253-36). They must not be welded.
Where nuts and bolts are used, they
must be of at least M8 size of ISO standard 8.8 or better.
Fasteners must be self-locking or
fitted with lock washers.
It should be noted that demountable
joints must not be used as part of a main, front or lateral rollbar because
they act as hinges in the principal structure and allow deformation. Their
use is solely for attaching members to the rollbars and for attaching a
lateral rollbar to a main rollbar (drawing
253-4). In this last case, hinged joints such as illustrated in drawings
253-30, 253-33 and 253-36 must not be used.
All welding must be of the highest
possible quality with full penetration and preferably using a gas shielded
arc. Although good external appearance of a weld does not necessarily guarantee
its quality, poor looking welds are never a sign of good workmanship.
When using heat-treated steel the
special instructions of the manufacturers must be followed (special electrodes,
gas protected welding).
It must be emphasised that the use
of heat-treated or high carbon steels may cause problems and that bad fabrication
may result in a decrease in strength (caused by brittle heat-affected zones)
or inadequate ductility.
(j) Other roll over protection designs.
(i) Roll over protection of alternate
material or design may be accepted by the scrutineer provided the entrant
can produce a certificate specifying the following: the quality of steel
used, the dimensions of the tubes, the optional reinforcing members and
the mounting to the vehicle, and that the construction is certified to
withstand the stress minima given hereafter in any combination on top of
the safety cage:
(*W = weight of the car + 150 kg).
The certificate, approved by CARS
and signed by qualified technicians, must be presented to the event's scrutineers.
It must contain drawings or photos of the
safety cage in question including its fixation and particularities, and
must declare that the rollcage can resist the forces specified above.
(ii) Vehicles having a log
book issued prior to January 1, 2000 and not meeting current regulations
may have their roll over protection accepted by the scrutineer provided
the safety cage meets the requirements described in Appendix 1.
(k) FIA homologated rollcages are
acceptable provided they are equipped with doorbars.
(a) Five or six point safety harness
of unmodified proprietary manufacture shall be fitted for both crew members.
(Note: It is not permitted to mix parts of seat belts. Only complete sets
may be used.) It is highly recommended that
the belts be homologated by the FIA and comply with FIA standard no 8854,
8853, 8854/98
or 8853/98. (Effective 2002/01/01, all safety harness systems must
have a date of manufacture label or stamp that is no older than five years
from the date of competition.
(b) A minimum five point system is
required for use in vehicles with upright seating (seat back angle is 35o
or less from the vertical), and shall consist of a lap belt, two shoulder
belts and an anti-submarine strap or
straps. The
harness shall bear an FIA homologation or the minimum width of the lap
and shoulder belts shall be 70 mm where it contacts the body and 25 mm
for the crotch strap.
(c) A six point system is required
for use in vehicles in which the seating position is semi-reclined (seat-back
angle exceeds 35o
from the vertical) and shall consist of a lap belt, two shoulder belts
and two leg or anti-submarine straps,
all of a minimum 50 mm width.
The
harness shall bear an FIA homologation or the minimum width of the lap
and shoulder belts shall be 70 mm 44mm for the remainder of the belts where
they contact the thighs and 25mm when they are not in contact with the
user.
(d) The material of all straps shall
be nylon
or Dacron polyester in new or
perfect condition. The belts must be equipped
with turn buckle, push button or lever style release systems. (Effective
2003/01/01, only turn buckle or push button release systems will be accepted.)The
buckles must be of metal-to-metal quick-release type except in the case
of the anti-submarine straps of the six-point system where they attach
to the lap belt or shoulder belts.
(e) The lap belt and anti-submarine
straps should not pass over the sides of the seat, but through the seat
in order to wrap and hold the pelvic region over the greatest possible
surface. The lap straps must fit tightly in the
bend between the pevic crest and upper thigh. area
and with the lap belt crossing the abdomen below the antero-superior iliac
spines ("hip bones"). (The belt should cross over the creases made
by the upper thighs and the abdomen, when seated.)
Under no circumstances may they be worn above the pelvic region.
Holes may
be made in the seat if this proves to be necessary in order to avoid such
an
occurrence.
Care must be taken that the straps cannot be damaged through chafing against
sharp edges.
(f) In all
cases, it is most preferable that safety harnesses be installed on the
anchorage points of the vehicle. The recommended geometrical locations
of the anchorage points are shown in drawing
253-42.
(g)
The shoulder harness shall be a two-strap over-the-shoulder type. ("H"
type configuration is permitted.) The
shoulder harness shall be mounted behind and below the wearer's shoulders
so as to make an angle of less than 20oIn
the downwards direction, the shoulder straps must be directed towards the
rear and must be installed in such a way that they do not make an angle
of more than 45o
to the horizontal from
the wearer's shoulders. from
the upper rim of the backrest, although it is recommended that this angle
should not exceed 10o.
The maximum angles in relation to the centre-line of the seat are 20o
divergent or convergent. Anchorage points creating a higher angle to the
horizontal must not be used unless the seat meets the requirements of the
FIA standard. A safety harness must not be installed on a seat
having no head restraint or having a backrest with integrated head restraint
(no opening between backrest and head restraint).
(If the seat does not provide lateral restraint, the mounting point on
the vehicle structure shall be a minimum of 50 cm behind the seat back
when measured along the belt.)
(h)
The single anti-submarine strap of the five-point system shall be attached
to the floor structure of the car similar to the shoulder belt mounting
and have a metal-to-metal connection with the single release common to
the seat belt and shoulder belts.
(i)
The double anti-submarine straps of the six-point system may be attached
to the floor as above for the five-point system or be attached to the seat
belt so that the driver sits on them, passing them up between the legs
and attaching them either to the quick-release buckle common to the lap
and shoulder belts or attaching them to the shoulder belts.
It is also permitted for the leg straps
to be secured at a point common to the lap belt attachment to the structure.
The straps shall then pass under the leg and up between the legs to the
quick-release buckle or shoulder belts.
(j)
The minimum acceptable size and grade
of bolt used in the mounting of all belts and harnesses shall be 0.5
inch, SAE grade 58,
UNF or, preferably, M12 8.8. When mounted, the bolts should
work in shear and not in tension.
(k)Where
possible, lap belts, shoulder belts and anti-submarine straps should be
mounted to the roll structure or frame of the vehicle. Where this is not
possible, they must be attached to a structural panel suitably reinforced
in a workmanlike manner to prevent distortion under load. Steel reinforcing
plates of an adequately large area and thickness must be installed to prevent
the belt attachments from pulling through the panel under load.
(k)If
installation on the series anchorage points is impossible for the shoulder
and/or crotch straps, new anchorage
points must be installed on the shell or the chassis, as near as possible
to the centre-line of the rear wheels for the shoulder straps. The
shoulder straps may also be fixed to the safety rollcage or to a reinforcement
bar by means of a loop, and may also be fixed to the top anchorage points
of the rear belts, or be fixed or leaning on a transversal reinforcement
welded to the backstays of the rollbar. In this case, the use of a transversal
reinforcement is subject to the following conditions:
(i) The transversal reinforcement
shall be a tube measuring at least 38 (1.5") mm x 2.5mm or 40 (1.6") mm
x 2 mm, made from cold finished unalloyed carbon steel, with a minimum
yield strength of 350 N/mm2.
(ii) The height of this reinforcement
must be such that the shoulder straps, towards the rear, are directed downwards
with an angle of between 10o
and 45o to the horizontal
from the rim of the backrest, an angle of 10o
being recommended.
(iii) The straps may be attached
by looping or by screws, but in the latter case an insert must be welded
for each mounting point (see drawings 253-17C and 253-53 for the dimensions).
These inserts will be positioned in the reinforcement tube and the straps
will be attached to them using bolts of M12 8.8 or 7/16 UNF specification.
(iv) Each anchorage point must
be able to withstand a load of 1470 daN, or 720 daN for the crotch straps.
In the case of one anchorage point for two straps, the load considered
will be equal to the sum of the required loads.
(v) For each new anchorage point
created, a steel reinforcement plate with a surface area of at least 40
cm2 and a thickness of at least 3 mm must be used.
(l) Principles of mounting
to the chassis/monocoque:
(i) General mounting system:
see drawing 253-43.
(ii) Shoulder strap mounting:
see drawing 253-44.
(iii) Crotch strap mounting:
see drawing 253-45.
(m)The
belts must be replaced after a severe collision. (Most manufacturers offer
reweaving of hardware.) Seat belts must also be replaced immediately should
the webbing become cut, frayed, or weakened due to the actions of heat,
chemicals or sunlight. They must also be replaced if hardware or buckles
are bent, deformed or rusted, or if the belt does not function properly.
A
safety harness must be used in its homologation configuration without any
modifications or removal of parts, and in conformity with the manufacturer's
instructions. The effectiveness and longevity of safety belts are directly
related to the manner in which they are installed, used and maintained.
The belts must be replaced after every severe collision, and whenever the
webbing is cut, frayed or weakened due to the actions of chemicals or sunlight.
They must also be replaced if metal parts or buckles are bent, deformed
or rusted. Any harness which does not function perfectly must be replaced.
(a) One fire extinguisher with a minimum
UL rating of 10 BC or two, each with a minimum rating of 5 BC, must be
installed inside the passenger compartment. During installation, consideration
must be given to quick release and security of attachment. One fire extinguisher
must be located within easy reach of the Driver or Co-Driver when seated.
(b) It is strongly recommended that
Halon or a similar gaseous extinguishant be used. If a dry powder unit
is used, the unit should be shaken or rapped sharply at frequent intervals
to reduce the chance of the powder compacting.
(e) A fire extinguisher label (available
through CARS) must be placed on the outside of the vehicle at the nearest
point of access to a fire extinguisher.
NOTE:
SCCA rules require that dry chemical extinguishers be recharged every six
months.

of access to a first-aid kit.
A minimum of three self-supporting,
light-reflecting, daylight-visible triangular warning devices of a minimum
size of 30 cm per side shall be carried in the vehicle. One
of which must be located within easy reach of the Driver or Co-Driver when
seated.
(a) Batteries must be securely mounted
with metal-to-metal mounts.
(b) If removed from the original location,
all batteries shall be mounted inside covered, non-conductive boxes.

shall be that which makes it easily operable by either crew member or by
persons outside the vehicle through either front door.
(c) The location of the circuit breaker
shall be marked with a label showing a red spark in a white-edged blue
triangle with a base length of at least 12 cm.
(a) The windshield shall be laminated
safety glass.
NOTE: While polycarbonate ("Lexan")
may be the current preferred substitute material, competitors would be
wise to pay attention in mounting all substitute materials with a particular
view to emergency escape and access in the event of an accident.
Mud flaps are required on all rear
wheels and driving wheels.
11. Fuel tanks and lines.
(a) A fuel-resistant and fire-retardant
plate or shield is required between the passenger compartment and the compartment
or area in which the fuel tank is located.
(b) The original fuel tank may only
be replaced by an FIA- or CARS-approved fuel cell provided that:
(i) The original fuel tank is removed.
(ii) The fuel cell is properly vented
to outside the vehicle from the compartment in which it is located.
(iii) The original fuel filler opening
is sealed, if not used for the fuel cell.
(iv) Should the fuel cell and its
filler be located in the luggage compartment, an outlet must be provided
for fuel spilled in the compartment.
(v) Where fuel cells are installed
in the passenger compartment of vehicles such as "hatchback" variants,
NRR II.C.11(a) above applies if the fuel cell filler is located in the
passenger compartment.
(c) Supplementary fuel tanks are not
permitted.
If fuel lines are re-routed through
the passenger compartment, they shall be in compliance with the following:
(i) Shall incorporate a metallic casing.
(If the metallic casing is not exterior to the line, a verifiable sample
must be presented at scrutineering.)
(ii) Shall have a minimum of 200 psi
rating. If fuel lines are routed through the passenger compartment by the
manufacturer, it is recommended that they be in compliance with this section.
(d) Fuel pumps shall be isolated from
the driver/co-driver by a fireproof metal bulkhead.
Mountings for seats other than original
must be such that they are securely attached to the floor of the vehicle
in such a manner as to prevent the movement of the seat in case of an accident.
Towing eyes shall be attached to the
front and rear of the vehicle and painted in yellow,
red or orange.
All articles which could be dangerous
if left loose must be securely restrained.
Inside door panels are required to
provide protection from metal edges.
All vehicles must carry a tow rope
or winch with cable.
Movable metal sunroofs and/or roof
panels must be fixed in the closed position. Sunroofs and/or roof panels
of any other material must be replaced with metal and must be fixed in
the closed position. The finished work must be of equal or greater strength
than the permanent roof.
18. Supplemental & Passive Restraints.
Airbags and their associated equipment
must be disabled or removed during competition in order to eliminate the
possibility of the airbag inflating accidentally. It is recommended that
passive restraint systems be disabled.
All parts of the vehicle, other than
the tires, must have a minimum of 5.0 cm clearance from a level road surface.
D. General Regulations

(i) A minimum of the top two-thirds
of the front door panels from the window line down is reserved for exclusive
use by CARS and/or its sponsors.
(a) Original headlights may not be
changed or removed. However, the frontal glass, reflector and bulbs are
free, provided they are in compliance with the legal requirements of the
province or state of registration.
(b) A headlight shall be considered
as any lighting device throwing a beam toward the front of the vehicle
(dipped-beam, long range lamp, anti-fog lamp). Auxiliary headlights may
be fitted, provided the number is even. These lights may be fitted into
the bumpers, radiator grillwork or the front part of the coachwork, provided
that such openings as needed in this case are completely filled by the
lights fitted.
(c) It must be possible to turn off
all high-beam headlights and auxiliary lights with a single switch, which
must leave the low-beam headlights functioning.

The maximum permitted noise level
from the exhaust system shall be 86 dbA with the engine idling at 3500
RPM, measured from a distance of 15 metres.
5. Turbocharger Restrictions.
All turbo-charged 4WD, with adjusted
displacements between 2350 cc and 4000 cc, must have a turbocharger air
inlet orifice of 40 mm diameter or less. If the turbocharger is equipped
with a larger inlet, the use of a restrictor is required. It must have
a minimum width (parallel to the direction of the airflow) of five (5)
mm and be placed within 50 mm of the turbocharger housing. All turbo-charged
4WD cars, with adjusted displacements greater than 4000 cc, must have a
turbocharger inlet or restrictor, similar to the above, of 36 mm diameter
or less.
If a car is fitted with two turbochargers,
then the total area of the two restrictors cannot exceed the area of the
restrictors listed above. As an example, for two restrictors of equal size,
the maximum diameters of each restrictor would be 28.3 mm for the 2350
cc to 4000 cc and 25.5 mm for the over 4000 cc.
The following
multipliers are to be applied to arrive at the adjusted displacement concerning
turbocharger restrictions:
rotary engines
1.8
turbo-charged
engines 1.7
three valves
per cylinder 1.1
four or more
valves per cylinder 1.15
pushrod engines
0.8
FIA Group
N vehicles must comply with FIA requirements concerning turbocharger restrictors
(32 mm)
(Effective
January 1, 2002), Open class vehicle turbocharger restrictor shall be 34
mm and all production vehicles shall be 32 mm.
The following documentation shall
be carried in the vehicle at all times:
(a) Vehicle registration.
(b) Proof of third party liability
insurance covering the entered vehicle.
(a) All competing vehicles in stage
events shall be identified with door numbers. These numbers will be supplied
by CARS for National rallies and are available from CARS for other rallies.
The numbers will be at least 20 cm (8 inches) high and 2.5 cm (1 inch)
stroke width. The numbers and any CARS supplied decals must be mounted
on the front doors according to Diagrams or to the directions of the event
chief scrutineer.
Vehicles registered in any of the
United States of America and running on SCCA licences
shall be acceptable provided that they meet the requirements of the current
SCCA Rally Rules. Entrants whose cars are entered under this provision
must be able to produce, upon request by the officials of the event, a
copy of the SCCA Pro Rally Rules. Failure to produce these rules may result
in the vehicle being judged according to CARS rules.
The vehicle must be based on a model built by a recognized
manufacturer listed in the NADA Official Used Car Guide. It is the intent
of these rules that all vehicles be based on production vehicles. Eligibility
is restricted to street-licenced, closed-bodied vehicles.
10. Adjusted Displacement
The following multipliers are applied to arrive at the
adjusted displacement:
Turbo/supercharged engines 1.7
Three (3) valves per cylinder 1.1
Four (4) or more valves per cylinder 1.15
All appropriate multipliers apply. For example, the multiplier
used for a rotary engine, four-wheel drive vehicle would be 1.8 x 1.3 =
2.34.
The cubic capacity is limited
as follows for normally aspirated engines:
3 l maximum for two valves per
cylinder.
2.5 l maximum for more than
two valves per cylinder.
In the event of turbo/supercharged
engines being used:
The nominal cylinder capacity
is limited to 2500 cm3 maximum.
The nominal cylinder-capacity
will be multiplied by 1.7 for petrol engines and by 1.5 for diesel engine
and the car will pass into the class corresponding to the fictive volume
thus obtained. The car will be treated in all respects as if its cylinder-capacity,
thus increased, were its real capacity.
In the event of rotary engines
being used:
A multiplier of 1.5 is applied
to arrive at the adjusted displacement.
Tires must be fully covered when viewed from above.
