GP2 drivers will have to manage tyre allocations from next season.
Mimicking the current F1 rules, drivers will be given a limited number of ‘prime’ and ‘option’ tyres per race weekend.
Three sets of the harder tyre and just one of the softer tyres will be available, and the harder tyres must be used in the Sunday sprint race. The mandatory pit stop in the longer Saturday race will remain.
GP2 and GP3 will adopt an F1-style points system from 2012. In the Saturday race the top ten will score 25, 18, 15, 12, 10, 8, 6, 4, 2 and 1 points respectively.
In the Sunday race, where the top eight on the grid are reversed, points will be awarded to the top eight finishers 15, 12, 10, 8, 6, 4, 2 and 1.
The Saturday pole sitter will be awarded an extra four points and two points will be given for the fastest lap in each race.
GP2 CEO Bruno Michel said: “Our series’ main goal has always been to prepare them to Formula 1 and so far we have been very successful at it.
“More than ever, tyre management is key to how quickly young drivers can adapt to the pinnacle of motorsport. However, although we will introduce a second compound, we have decided to keep only four sets of tyres per race weekend in order to control the costs.
“It will be interesting to watch as our teams will put in place the best possible strategy. It will add even more suspense, but it will also make tyre management all the more delicate.”
