Revised Qualifying Format
• Cars are under Parc Ferme conditions throughout qualifying.
• Tyre specification must be made prior to qualifying rather than 08:00 on Saturday morning.
• Qualifying One begins at 14:00 for 15 minutes and all cars will be permitted on track for fifteen minutes and have no limit on laps. At the end of the session the six slowest cars are eliminated.
• The lap times of the remaining cars are deleted for the next session.
• Qualifying Two follows the same format as session one and takes place between 14:20 and 14:35.
• Qualifying Three, the last session, runs between 14:40 and 15:00 and the remaining ten grid positions are decided on the times in this session.
• During Qualifying One and Qualifying Two fuel may be added at any time and cars eliminated in these sessions will be free to refuel at any time until the pitlane opens for the race.
• Cars participating in Qualifying Three will be required to start the session with the amount of fuel they wish to start the race with.
• At the end of qualifying six cars will be chosen by the FIA at random to undergo further tests.

The Grid
• Last six positions will be the cars eliminated from the first qualifying session. The fastest will be in 17th position.
• The next six positions will be occupied by the cars eliminated in the second qualifying session, the fastest in 11th position.
• The top 10 positions will be filled with the cars which drove in Qualifying Three; the fastest will be on pole position.
• If two drivers set identical times in any of the three qualifying sessions priority will be given to the one who set it first.
• If one driver fails to set a time in any qualifying session they will be arranged in the following order.

• any driver who attempted a flying lap.
• any driver who failed to start a flying lap.
• any driver who failed to leave the pits in this period.

• Any driver who incurs a penalty is placed behind the last car from Qualifying One.
• In the above cases if more than one driver falls into a single category they will be arranged on the grid in numerical order.

Tyre use and allocation
• No driver may use more than one specification of dry weather tyre after the start of the qualifying practice session.
• During the event no driver may use more than seven sets of dry weather tyres, four sets of wet weather tyres and three sets of extreme weather tyres.
• The restriction on tyres during the race is no longer in place.

Parc Ferme Conditions
• The car must be in parc ferme from the time it leaves the pit lane for the first time during qualifying until the green lights are on at the start on the formation lap.
• You are now allowed to:

• start engines.
• add fuel and a fuel breather.
• wheels and tyres may be changed, rebalanced, and the pressure changed.
• spark plugs may be removed.
• heating devices fitted.
• jump battery fitted.
• tape added to body work.

Engine
• All engines must have 8 cylinders and be 2.4 litres, weigh no less than 95kg and have two inlet and two exhaust valves.
• The centre of gravity of the engine in the car has been fixed so that the engine configuration cannot be an advantage.

Alternative Engines
• For 2006 and 2007 only, the FIA reserve the right to allow any team to use an engine complying with the 2005 engine regulations.
• The restrictions on this rule are that its maximum crankshaft rotational speed does not exceed a limit fixed from time to time also the air intake to the engine is restricted by the max diameter to the air box being 77mm by the FIA so as to ensure that such an engine will only be used by a team which does not have access to a competitive 2.4 litre V8 engine.

Chassis
• The deflectors which used to be level with the reference plain have now been raised to the step plain.
• The impact speed for the rear crash test has increased from 12m/s to 15m/s.
