The FIA have ruled that in order to help Pirelli with the construction of their new 18-inch Formula 1 tyres set to be introduced in 2022, modified F1 cars from the upcoming season can be used - and this is welcome news for McLaren.
Pirelli have 25 days of testing to share among the teams in order to aid the switch from 13-inch tyres to the bigger 18-inch tyres that are to be run in 2022. However, prior to this reconsideration, only cars from the 2018, '19 and '20 seasons were allowed, which caused a problem for McLaren who are switching to Mercedes power this year and no longer have access to Renault technical support.
But it's now been reported by Motorsport.com that the FIA has changed its stance, meaning the Woking-based team - and every team for that matter - will now be able to run their 2021 challenger provided they make some modifications.
At the moment no dates have been set for these tests and there are no plans for any testing days to take place before the season gets underway.
