The GP2 Series is a one-make championship consisting of 26 identical cars. The chassis are designed by Dallara Automobili, and in 2012 will run under the specification GP2/11. The power base is a Mecachrome assembled 4L Renault V8 engine.
The GP2 Series uses slick Pirelli tyres in four specifications (super soft, soft, medium and hard) which are predetermined by Pirelli in advance of the race weekend.
In a change of regulations in 2012, each driver has five sets of dry-weather tyres per weekend – three of “prime” specification and two of “option” specification. Each driver will also be provided with three sets of wet-weather tyres.
Once used in free practice, one set of “prime” specification must be returned to Pirelli before the start of the qualifying practice session. As such, each driver will still have four sets - two sets of Primes and two sets of Options - to use freely during qualifying, Feature Race and Sprint Race.
The compulsory pit-stop during Race One remains in which a minimum of two tyres must be changed. This pit stop may not be carried out until the driver has completed six laps.
Tyre colour codes for 2013
Hard - ORANGE
Medium - WHITE
Soft - YELLOW
Super Soft - RED
Wet - BLUE
No individual developments or upgrades are permitted in the series, and all spare parts must be purchased directly from the GP2 Series. Repairs of structural components must be carried out by Dallara in order to ensure integrity.
Weekend format and points allocation
A race weekend is composed of one half hour practice session and one half hour qualifying session, followed by two races.
The qualifying session is a straight fight for fastest laptime, and determines the order of the grid for Race 1. In a change of regulations in 2012, four points are awarded for pole position.
Race 1 is run over 170km or 60 minutes (except for Monaco and Singapore where the race is run over 140km), and each driver must complete one compulsory pitstop in which a minimum of two tyres must be changed.
In a change of regulations in 2012, the top ten drivers score points (25, 18, 15, 12, 10, 8, 6, 4, 2, 1) with two points being awarded to the driver who set the fastest lap of the race.
The grid for Race 2 is determined by the finishing order of the first race, with the top 8 positions reversed. Race 2 is run over 120km or 45 minutes (except for Monaco and Singapore where the race is run over 100km), with no pitstops allowed.
In a change of regulations in 2012, the top eight finishers score points (15, 12, 10, 8, 6, 4, 2, 1) and the driver who sets the fastest lap scores two points.
Any driver who is not classified in the top ten positions at the end of the race or, didn’t start the race from his normal grid position or, changed tyres during race two at a time when climatic conditions did not necessitate the use of a different specification of tyre, will not be eligible for points awarded for fastest lap.
