London: The all-female W Series will be part of the Formula One (F1) support programme in its second season with new races at the US and Mexican Grands Prix in October, organisers announced on Thursday.
The W Series, conceived as a platform to help women gain experience to help them climb up the motorsport ladder and compete with the men, started last year with six races at European circuits.
Those behind it have made no secret of their global ambitions, however.
The races at the Circuit of the Americas in Austin, Texas, and Mexico City's Autodromo Hermanos Rodriguez expand the second season to eight rounds with the other six accompanying the DTM German Touring Car championship.
"In just one year, W Series has contributed significantly to increasing interest in the topic of diversity and inclusion in motorsport," Ross Brawn, Formula One's managing director for motorsport, said in a statement.
"We are convinced that our sport must offer equal opportunities for men and women to compete together," added the Briton.
"It is no coincidence that improving the diversity of the F1 grid by supporting and promoting driver talent from under-represented backgrounds is one of our strategic objectives."
Formula One has not had a female racer line up on the starting grid since 1976.
W Series chief executive Catherine Bond Muir said she was thrilled her championship would be a part of the two weekends.
"I’m particularly pleased that W Series will now stage races outside Europe, and the USA and Mexico are of course both very important new territories for us," she said.
The American races will be on successive Saturdays when F1 qualifying is the main draw. The two Grands Prix have been F1 title-deciders for four of the last five years.
Both circuits have also been keen to show greater inclusivity in a male-dominated sport and have space on support programmes without the usual junior series.
"The fact that W Series will be even bigger and even better in 2020 than it was in 2019 will make the return on investment for our future sponsor-partners better and bigger, too," said Bond Muir.
The 2019 title, with a prize of $500,000, was won by Britain's Jamie Chadwick who is also a development driver for the Williams Formula One team.
Former F1 racer David Coulthard, who competed in 246 Grands Prix between 1994 and 2008, is the chairman of the W Series advisory board.
"It (the agreement) demonstrates very clearly the extent to which W Series has quickly been widely accepted as part of the international motorsport calendar," said the Scot.
