This year's schedule has been severely disrupted by the coronavirus pandemic and earlier this week the Dutch Grand Prix became the latest race to be cancelled.
The much-delayed 2020 world championship will begin with the first event of an Austrian double-header on July 5, before travelling to Hungary, Silverstone for two races, then Spain, Belgium and finally Italy on September 6.
The remaining races on the calendar would follow the same format as previously, which has been in place since 2010.More news: Amid standoff, China builds road to mineral rich area
After the July 5 and 12 races in Austria, the only other double-header now planned is at Silverstone, which - notwithstanding lack of clarity over exemptions from the United Kingdom government's new 14-day quarantine procedure for F1 personnel - will in theory host the fourth and fifth rounds, following a single race in Hungary.
It would take the place of holding the traditionally stand-alone qualifying single lap speed trials.
Liberty's idea means that for one of the two races in Austria and Great Britain the normal qualification will be replaced by a 30 minute sprint race.More news: Music composer Wajid Ali of Sajid-Wajid duo passes away
Formula 1 staring grid.
F1 hoped to get the heavily-delayed 2020 season off the ground with back-to-back races in Austria in early July before returning to Britain for another double-header event at Silverstone, but the plans were dented by the introduction of the United Kingdom government's new quarantine rules which will force global arrivals to observe a 14-day quarantine period from June 8. Not that this handicap seems to have prevented Fernando Alonso from scooping successive sweeps in the series, however. Grid penalties such as those for a gearbox change after FP3, will be applied to the main race on Sunday.
That was dropped when two teams, one of them Mercedes, voted against. The FIA introduced a measure during the corona crisis that a majority of 60% is enough to make urgent changes to the regulations, but a new qualification format is not included.More news: 2 officers fired after video shows college students pulled from vehicle , tased
