Sebastien Bourdais revealed exclusively to Autosport magazine this week that he is considering a return to racing in North America if he is left without a drive in Formula One next season.
The four-time Champ Car champion is still in contention for a seat at Scuderia Toro Rosso next season along with Sebastien Buemi and Takuma Sato, but says he will look to return to the states if he is not retained by the team.
"I'm pretty open," he told Autosport. "Right now I need a good programme and America would be an interesting option.
"I have been looking at alternatives (to F1) because that's my job. I need to find a way to make a living, but that's not easy right now - everybody is not willing to commit to any programmes."
A return to Bourdais' former Newman/Haas team is unlikely with the team struggling to raise sponsorship for a second car. Graham Rahal is expected to stay on with the team and Justin Wilson has already been told he is free to look for other drives.
