Kamui Kobayashi is keen to return to F1 next season but if he doesn't has promised to refund all those who sponsored him.
With his position in Formula One on the line near the end of last season, the then-Sauber driver started a website to bring in sponsorship.
The Japanese driver raised £1.2 million but still was not able to save his Formula One career.
Kobayashi, though, is refusing to give up and has set his sights on a race seat for next season.
However, should that fail to materialise, he has promised to pay back all those sponsored him.
"I want to come back to Formula one next year," crash.net reports him as having said, "and there is one thing I want to be clear about 'Kamui Support'.
"The donations of Kamui Support have not been used at all this year, because this was purely for F1 seat.
"If I don't need to use them for next year's F1 seat, I want to return all to [those] whom made donation."
