Kamui Kobayashi says he will refund those fans who pledged financial support to try and keep him on the F1 grid if he fails to secure a place on the grid next year.
The Japanese racer found himself without a drive for the 2013 campaign after a lack of sponsorship saw him replaced by Sauber, with a support programme being set up to try and help him secure a role elsewhere.
Despite raising more than £1.2 million, Kobayashi failed to secure an F1 race seat and has instead moved into sportscars having inked a deal to compete in a Ferrari
458 Italia for AF Corse in the World Endurance Championship.
Writing in a message on his official website, Kobayashi admitted he was enjoying his season in sportscars but remained focused on making it back to F1 next year.
Should he fail to secure a drive, the 26-year-old insisted he would refund those who have pledged financial support to get him back on the grid, stating he would only use the money towards an F1 drive.
“I want to come back to Formula one next year,” he 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.”
