Pirelli, the FIA and the F1 teams are pushing ahead with plans for a one-day post-Abu Dhabi GP tyre test after various hurdles were addressed.
One of the keys has been an agreement that Force India and Sauber can run rookie drivers, in addition to one of their race drivers. The two teams were the biggest objectors to the test.
Both teams regularly use testing as a source of income but that had initially been blocked by Pirelli's original insistence that only race drivers, or reserves with plenty of 2015 track mileage could be used.
Teams had questioned the cost of the test, not least because many will have to change flights at considerable expense. Manor has already indicated that it will not take part.
The World Motor Sport Council has began the process of authoring the test on safety grounds on the basis of the new constructions.
As previously reported, the test will run for 12 hours, from 9am to 9pm, and teams are expected to run around 500kms apiece.
"We are finalising some details," said Pirelli's Mario Isola when asked by Motorsport.com. "The test is going to happen, but we need to finalise with some details with the teams and the FIA.
"As soon as we have confirmation of the number of cars that are attending the test and the ability of the drivers and so on, we will make our run plans, and start to be more precise on what is going to happen in Abu Dhabi.
"First of all as you know there is a big discussion for next year, to add one compound, for sure to develop a new compound with track testing. We will test some different solutions also of constructions. These are the main targets of the test."
