The new A1 Grand Prix series has signed up ex-Formula One world champions Alan Jones and John Surtees.
Jones, F1 champion in 1980, will head the Australian team, while 1964 champion Surtees is involved with a British team.
The A1 series is due to start in September next year and will feature up to 20 drivers competing for national teams, all using identical cars.
Teams from nine countries have so far been confirmed to take part.
Organisers said that Portugal's franchise holders will
involve Real Madrid star Luis Figo and former Real Madrid coach
Carlos Queiroz, who is now assistant to manager Alex Ferguson at
Malaysia's entry will be run by Alex Yoong, who was the first
F1 driver from the south-east Asian country.
The series is hoping to tap the winter months during the F1 off-season.
