They're going to get female drivers from a variety of classes. Stéphane Kox says she has been approached, and she drives in GT4. She says they had a long list and they're now getting it down to a shorter list.
You could make a list like:
Tatiana Calderon (GP3)
Jamie Chadwick (F3)
Sophia Flörsch (F3)
Amna Al Qubaisi (F4)
Miki Koyama (F4)
Alexandra Mohnhaupt (F3/F4)
Marylin Niederhauser (F4)
Julia Pankiewicz (Formula Renault)
Sabre Cook (USF2000)
Beitske Visser (GT4)
Chelsea Angelo (GT3)
Bianca Anton (GT4)
Laura Kraihamer (GT4)
Ashley Freiberg (GT4)
Sarah Bovy (GT3/Blancpain)
Esmee Hawkey (Porsche Carrera Cup)
Katilyn Hawkins (APC)
Chelsea Herbert (NZ V8)
Amy Smith (NZ Formula First)
Nicole Behar (Nascar K&N)
Julia Landauer (Nascar K&N)
Carmen Boix Gil (Nascar Whelen)
Ellexandra Best (Toyota 86)
Michelle Halder (STT)
Francesca Linossi (Super Trofeo)
Carrie Schreiner (Super Trofeo)
Jasmin Preisig (TCR)
Jessica Bäckman (TCR/STCC)
Vivien Keszthelyi (Audi LMS Cup)
Michelle Gatting (DTC)
there are some more girls in the junior categories in the US/AUS and perhaps regional F4 etc.
perhaps even:
Simona De Silvestro (V8 supercars)
Christina Nielsen (Imsa)
I guess the idea is to promote female racing and show girls what is possible. Might be interesting for someone like Marta Garcia, who's in karting and taking wins.
