F1 is considering installing a third Friday practice session for the 2012 weekend format.
The proposal is the result of recent talks about slightly relaxing the current total ban on in-season testing, and particularly its impact on the development of young drivers.
"We should not go back to what we had, but in between there is a compromise," said Renault team boss Eric Boullier, who is also deputy chairman of the F1 teams association FOTA.
"We have proposed to have a short extra session on Friday in which young drivers are used," the Frenchman revealed to German website motorsport-total.com.
The report said the proposal is for a half-hour session before Friday's first official practice.
"It should be a separate test session for which a separate set of tyres is available," added Boullier.
