The final two rounds of W Series will take place as part of Formula 1’s support package, at the United States and Mexico City Grands Prix respectively.
The second season of the women-only single-seater series will now comprise eight races, with Austin and Mexico City joining the already confirmed six events that will support the DTM championship.
The races will take place on Saturday 24 and 31 October respectively, with the final race likely to determine the title-winner, which in 2019 was Williams-backed racer Jamie Chadwick.
Formula 1 chief Ross Brawn said: “We are delighted to welcome W Series to two such spectacular events of the 2020 FIA Formula 1 World Championship, such as those at Austin and Mexico City.
“In just one year, W Series has contributed significantly to increasing interest in the topic of diversity and inclusion in motorsport.
“The ability for the great crowds, who traditionally attend the Austin and Mexico City Grands Prix, to see these talented female drivers up close will definitely further raise the awareness of the importance of inclusion and diversity in motorsport.”
Catherine Bond Muir, Chief Executive Office for W Series said: “Interest and enthusiasm for W Series was enormous in our first season in 2019, among media and fans alike, and the addition of two all-new W Series races on the Formula 1 platform will inevitably increase that enthusiasm and interest.
“Commercially, too, following the successful recent announcement of W Series’ new multi-year sponsor-partnership with ROKiT Phones, the fact that W Series will be even bigger and better in 2020 than it was in 2019 will make the return on investment for our future sponsor-partners better and bigger too.
“A lot of work has gone into stitching the W Series/Formula 1 deal together, but above all I want to thank W Series’ drivers, the brave and talented young women who captured the imagination of the sporting world last summer.
“Mark my words: they’ll do so again this year, from May to October, all over the world.”
