Romain Grosjean has revealed there is a performance clause in his Lotus deal that would allow him to leave the team.
The Frenchman has yet to commit his future to Lotus, who are nearing the end of a dreadful 2014 season.
Last year Lotus were fighting for podium finishes but this year they are struggling even to get close to the points.
Grosjean has scored the team’s only points, netting eight after back-to-back P8s in Spain and Monaco.
Next season, though, could be a better one for the team as they are swapping from Renault to Mercedes power.
But whether that’s enough to persaude Grosjean to re-sign remains to be seen.
For now he’s refusing to put to pen to paper until such a time as the seats at the top teams are filled.
“I have the option to leave if I want to – this is from some performance clause,” he revealed.
“So far there are still places available at top teams or they haven’t been confirmed and that’s there where I want to be in the near future and that’s what we try to do.”
That, though, doesn’t mean Lotus is out of the running as Grosjean is encouraged by their plans for next season.
“For a long time I’ve said that Lotus will be much better next year than they are this year, for a few reasons. There’s been a lot of work at the factory and the fact that the team brings a new nose here just to try to prepare for 2015 is a strong sign.”
