2011 season changes

Published with permission from the Federation Internationale de l'Automobile.

From the 2011 Formula One Technical Regulations:
3.18 Driver adjustable bodywork
3.18.1
The incidence of the rearmost and uppermost closed section described in Article 3.10.2 may be varied
whilst the car is in motion provided :
- It comprises only one component that must be symmetrically arranged about the car centre line with
a minimum width of 708mm.
- With the exception of minimal parts solely associated with adjustment of the section, no parts of the
section in contact with the external airstream may be located any more than 355mm from of the car
centre line.
- With the exception of any minimal parts solely associated with adjustment of the rearmost and
uppermost section, two closed sections are used in the area described in Article 3.10.2.
- Any such variation of incidence maintains compliance with all of the bodywork regulations.
- When viewed from the side of the car at any longitudinal vertical cross section, the physical point of
rotation of the rearmost and uppermost closed section must be fixed and located no more than
20mm below the upper extremity and no more than 20mm forward of the rear extremity of the area
described in Article 3.10.2 at all times.
- The design is such that failure of the system will result in the uppermost closed section returning to
the normal high incidence position.
- Any alteration of the incidence of the uppermost closed section may only be commanded by direct
driver input and controlled using the control electronics specified in Article 8.2.
3.18.2 The adjustable bodywork may be activated by the driver at any time prior to the start of the race and, for
the sole purpose of improving overtaking opportunities during the race, after the driver has completed a
minimum of two laps after the race start or following a safety car period.
The driver may only activate the adjustable bodywork in the race when he has been notified via the control
electronics (see Article 8.2) that it is enabled. It will only be enabled if the driver is less than one second
behind another at any of the pre-determined positions around each circuit. The system will be disabled by
the control electronics the first time the driver uses the brakes after he has activated the system.
The FIA may, after consulting all competitors, adjust the above time proximity in order to ensure the stated
purpose of the adjustable bodywork is met.

3.15 Aerodynamic influence
With the exception of the driver adjustable bodywork described in Article 3.18 (in addition to minimal parts
solely associated with its actuation) and the ducts described in Article 11.4, any specific part of the car
influencing its aerodynamic performance :
- must comply with the rules relating to bodywork ;
- must be rigidly secured to the entirely sprung part of the car (rigidly secured means not having any
degree of freedom) ;
- must remain immobile in relation to the sprung part of the car.
Any device or construction that is designed to bridge the gap between the sprung part of the car and the
ground is prohibited under all circumstances.
No part having an aerodynamic influence and no part of the bodywork, with the exception of the skid block
in 3.13 above, may under any circumstances be located below the reference plane.
With the exception of the parts necessary for the adjustment described in Article 3.18, any car system,
device or procedure which uses, or is suspected of using, driver movement as a means of altering the
aerodynamic characteristics of the car is prohibited.

4.1 Minimum weight :
The weight of the car must not be less than 640kg at all times during the Event.
If, when required for checking, a car is not already fitted with dry-weather tyres, it will be weighed on a set of dryweather
tyres selected by the FIA technical delegate.

4.2 Weight distribution
For 2011 only, the weight applied on the front and rear wheels must not be less than 291kg and 342kg respectively at
all times during the qualifying practice session.
If, when required for checking, a car is not already fitted with dry-weather tyres, it will be weighed on a set
of dry-weather tyres selected by the FIA technical delegate.

10.3 Suspension members :
10.3.6
In order to help prevent a wheel becoming separated in the event of all suspension members connecting it
to the car failing provision must be made to accommodate flexible tethers, each with a cross sectional area
greater than 110mm². The sole purpose of the tethers is to prevent a wheel becoming separated from the
car, they should perform no other function.
The tethers and their attachments must also be designed in order to help prevent a wheel making contact
with the driver's head during an accident.
Each wheel must be fitted with two tethers each of which exceed the requirements of 3.1.1 of Test
Procedure 03/07.
Each tether must have its own separate attachments at both ends which :
- are able to withstand a tensile force of 70kN in any direction within a cone of 45° (included angle)
measured from the load line of the relevant suspension member ;
- on the survival cell or gearbox are separated by at least 100mm measured between the centres of
the two attachment points ;
- on each wheel/upright assembly are located on opposite sides of the vertical and horizontal wheel
centre lines and are separated by at least 100mm measured between the centres of the two
attachment points ;
- are able to accommodate tether end fittings with a minimum inside diameter of 15mm.
Furthermore, no suspension member may contain more than one tether.
Each tether must exceed 450mm in length and must utilise end fittings which result in a tether bend radius
greater than 7.5mm.

From the 2011 Formula One Sporting Regulations:
25.4 Use of tyres :

Tyres will only be deemed to have been used once the car's timing transponder has shown that it has left the pit lane.
a) Three sets of dry-weather tyres will be allocated by the FIA technical delegate to each nominated driver for use during P1 and P2, two of “prime” specification and one of “option” specification. These are the only dry-weather tyres which may be used during these sessions.
One set of “prime” specification must be returned to the tyre supplier before the start of P2 and one further set of “prime” specification and one set of “option” specification before the start of P3.
If Article 25.2(c) is invoked an additional set of “prime” specification tyres will be available to each
nominated driver for use during P1 and P2. One set of “prime” specification tyres must be returned to
the tyre supplier after P1 and two further sets of “prime” specification and one set of “option”
specification before the start of P3.
If an additional driver is used (see Article 19.1(b) he must use the tyres allocated to the nominated
driver he replaced.
b) If an additional specification of dry-weather tyre is made available in accordance with Article 25.1 two sets of these tyres will be allocated to each driver for use during P1 and P2. Any such tyres must be returned to the tyre supplier before the start of P3.
c) Eight further sets of dry-weather tyres will be allocated by the FIA technical delegate to each nominated driver, four of each specification, for use during the remainder of the Event. However, one set of each specification must be returned to the tyre supplier before the start of the qualifying practice session and may not be used during the remainder of the Event.
d) Prior to the start of the qualifying practice session intermediate and wet-weather tyres may only be used after the track has been declared wet by the race director, following which intermediate, wet or dry-weather tyres may be used for the remainder of the session.
e) At the start of the race each car which took part in Q3 must be fitted with the tyres with which the driver set his grid time. This will only be necessary if dry-weather tyres were used to set the grid time and if dry-weather are used at the start of the race.
Any such tyres damaged during Q3 will be inspected by the FIA technical delegate who will decide, at his absolute discretion, whether any may be replaced and, if so, which tyres they should be replaced with.
f) Unless he has used intermediate or wet-weather tyres during the race, each driver must use at least one set of each specification of dry-weather tyres during the race.
If the race is suspended and cannot be re-started, thirty seconds will be added to the elapsed time of any driver who was unable to use both specifications of dry-weather tyre during the race. However, any driver who completes the race without using both specifications of dry-weather tyre will be excluded from the race results.
g) If the race is started behind the safety car because of heavy rain (see Article 40.14), or resumed in accordance with Article 42.5(a), the use of wet-weather tyres until the safety car returns to the pits is compulsory.

28) SPARE CARS, ENGINES AND GEARBOXES
28.6
For the purposes of this Article only, an Event will be deemed to comprise P3, the qualifying practice
session and the race.
a) Each driver may use no more than one gearbox for five consecutive Events in which his team
competes. Should a driver use a replacement gearbox he will drop five places on the starting grid at
that Event and an additional five places each time a further gearbox is used.
Any replacement gearbox must be fitted with the same gear ratios that were declared under d) below
and will only be required to complete the remainder of the Event in question. Any change to the gear
ratios declared under d) below will incur a further five grid place penalty. In either case a new five
race sequence may start at the following Event.
Unless the driver fails to finish the race (or is unable to start the race for reasons other than a penalty
imposed by the stewards) the gearbox fitted to the car at the end of the Event must remain in it for
the remainder of the five race sequence. Any driver who failed to finish the race at the first, second,
third or fourth of the five Events for reasons which the technical delegate accepts as being beyond
the control of the team or driver, may start the following Event with a different gearbox without a
penalty being incurred.
A gearbox will be deemed to have been used once the car's timing transponder has shown that it has
left the pit lane.
b) If a driver is replaced after the first, second, third or fourth Event of a five Event period, having
finished the first, second, third or fourth Events, the replacement driver must use the gearbox which
the original driver had been using.
f) For 2011 only, except during the last Event of the Championship season, each driver will be
permitted to use a replacement gearbox without incurring a penalty the first time this becomes
necessary during the season. Under such circumstances the replacement gearbox will only be
required to complete the remainder of the Event in question.

36) THE GRID
36.3
During Q1, any driver whose best qualifying lap exceeds 107% of the fastest time set during that session
will not be allowed to take part in the race. Under exceptional circumstances however, which may include
setting a suitable lap time in a free practice session, the stewards may permit the car to start the race.
Should there be more than one driver accepted in this manner, the grid order will be determined by the
stewards.In either case, a competitor will not be able to appeal against the stewards decision.

30) GENERAL SAFETY
30.19
No team personnel who are associated in any way with the operation of the cars are permitted within the
confines of the circuit during two six hour periods which commence ten hours before the scheduled start
times of P1 and P3.
However, each team will be permitted four individual exceptions to the above during a Championship
season.

16) INCIDENTS
16.3
The stewards may impose any one of the penalties below on any driver involved in an Incident :
a) A drive-through penalty. The driver must enter the pit lane and re-join the race without stopping.
b) A ten second time penalty. The driver must enter the pit lane, stop at his pit for at least ten seconds and then re-join the race.
If either of the two penalties above are imposed during the last five laps, or after the end of a race, Article 16.4b) below will not apply and 20 seconds will be added to the elapsed race time of the driver concerned in the case of a) above and 30 seconds in the case of b).
c) A time penalty.
d) A reprimand.
If any of the four penalties above are imposed they shall not be subject to appeal.
e) A drop of any number of grid positions at the driver's next Event.
f) Exclusion from the results.
g) Suspension from the driver's next Event.
