43) A competitor may change the make and/or type of engine at any time during the Championship. All points scored with an engine of different make to that which was first entered in the Championship may count (and may be aggregated) for the assessment of a commercial benefit, however such points will not count towards (nor be aggregated for) the FIA Formula One Constructors Championship. A major car manufacturer may not directly or indirectly supply engines for more than two teams of two cars each without the consent of the FIA. For the purposes of this Article 43, a major car manufacturer is a company whose shares are quoted on a recognised stock exchange or the subsidiary of such a company.

46) No more than 24 cars will be admitted to the Championship, two being entered by each competitor.

58) If one of the team's nominated drivers is unable to drive at some stage after the end of initial scrutineering, and the stewards consent to a change of driver, the third driver may take part in the remainder of the Event. Under such circumstances the driver concerned must use the engine, gearbox and tyres which were allocated to the original driver,

63) Testing shall be considered any track running time undertaken by a competitor entered in the Championship. Any other track running time undertaken by, or on behalf of a competitor entered in the Championship (or which is suspected of being connected in any way whatsoever with a competitor entered in the Championship) is not permitted.

74) Grooved tyres withdrawn

Spare Cars and Engines

83) Except when a car is being run under Article 58(b), each competitor may have no more than two cars available for use at any one time during an Event. Any partially assembled survival cell will be deemed to be a car in this context if it fitted with an engine, any front suspension, bodywork, radiators, oil tanks or heat exchangers.

86) Each driver may use no more than one engine for two consecutive Events in which his team competes. Should a driver use a replacement engine he will be required to comply with a minimum weight limit 15kg higher than stated in Article 4.1 of the 2008 FIA Formula One Technical Regulations at that Event each time an engine other than the original one is used. Unless the driver fails to finish the race (see below) the engine fitted to the car at the end of the Event must remain in it until the end of the next. Any driver who failed to finish the race at the first of the two Events for reasons beyond the control of the team or driver, may start the second with a different engine without a penalty being incurred.

Only engines which have been homologated by the FIA in accordance with Appendix 6 may be used at an Event during the 2008, 2009 and 2010 seasons.
