Pierre Gasly has said that he is not sure if he will vacate his new Formula 1 seat next month to take a shot at winning the 2017 Super Formula title.
As GP2 champion, the Frenchman was sent to Japan this year by backer Red Bull as he waited for a vacancy at the junior F1 team Toro Rosso, but Gasly has now made his F1 debut in axed Daniil Kvyat's place in Malaysia.
"We thought it was a good time to test him," Toro Rosso boss Franz Tost told Finnish broadcaster C More.
"We are taking him into consideration for next year."
"He will definitely be in Japan [for next weekend's grand prix] and then we will look at the situation after that. But I am sure he will be in the car more often this season."
After this Malaysia-Japan double header, F1 heads to Austin - which clashes with the Super Formula season finale at Suzuka.
Gasly, 21, admits that he would like a shot at the title.
"A title is always important," he said in Malaysia.
"After the championship in GP2, this was of course my next goal. But it would also be great if I could drive in Austin. I don't know where I'd rather be.
"I think if I knew I could finish the entire F1 season, I'd rather be in Austin. Formula 1 is my big goal."
Gasly said that he also has not been guaranteed the full-time Toro Rosso seat for 2018.
"They have not spoken to me about my future," he insisted. "Of course if it was up to me, I would have signed the contract for next year already."
Toro Rosso sit sixth in the constructors' standings ahead of today's race.
