LONDON -- Formula One added four more races to this year's calendar on Tuesday and said "a limited number of fans" will be able to attend some of the remaining events in the pandemic-disrupted season.
Races in Turkey, Abu Dhabi and two in Bahrain will take place in November and December, completing the heavily reshaped calendar and marking the latest finish to an F1 season since 1963.
It takes the number of races in the 2020 season to 17, which is the fewest staged in a year since 2009.
After a first Turkish Grand Prix at Istanbul Park in nine years on Nov. 15, Bahrain will stage back-to-back races on Nov. 29 and Dec. 6. The season will finish with the Abu Dhabi Grand Prix on Dec. 13.
The Chinese Grand Prix, which had been postponed, will not take place in 2020.
"We can confirm that a number of races in the revised 2020 season will be open to a limited number of fans, including hospitality," Formula One said in a statement, "and we are working with each promoter to finalize the details."
It did not specify which races would be open to spectators.
The Belgian Grand Prix at Spa-Francorchamps this weekend will be the seventh race of a season that is being packed into 5 1/2 months.
Lewis Hamilton holds a 37-point lead over Max Verstappen as the British driver seeks to become world champion for a seventh time, tying Michael Schumacher's record.
