Inaugural champion Jamie Chadwick will return for a second season of the all-female W Series in 2020, with six newcomers featuring on a list of 18 drivers published by organizers on Monday.
The new entrants for Season 2 include British racer Abbie Eaton, who has been a test driver for Amazon's "The Grand Tour" television motoring series.
Russian Irina Sidorkova will be the youngest in the championship at the age of 16.
Two Spanish F4 racers - Belen Garcia and Nerea Marti - are among the new faces along with Brazilian Bruna Tomaselli and Norwegian Ayla Agren.
Two other drivers will be announced at a later date to bring the field up to 20. The top 12 from this year's championship are all returning.
The W Series, which uses identical 1.8-liter Formula Three cars, aims to help female racers climb the male-dominated motorsport ladder towards Formula One, which last saw a woman start a race in 1976.
Season 2 looks set to feature more than the current six races, with the champion collecting a $500,000 prize as well as points towards the super licence that is mandatory for racing in Formula One.
