Grosjean in no rush to decide future
Romain Grosjean says he will hold off making a decision on where he will be next season for "as long as options are open".
Lotus has confirmed Pastor Maldonado will stay on for 2015 but is yet to reveal who will be the team's second driver. There are rumours in the paddock that Lotus may replace Honda-bound McLaren as the final Mercedes customer next year but Grosjean wants everything to be clear before making a decision.
When asked how long he would dwell on his future Grosjean, who says there is currently no deadline for his decision at Lotus, said: "As long as options are open!"
Grosjean hints the engine supplier would be a key factor in any decision he made.
"It's quite easy to quantify the lap-time difference if you change engine and then it gives you how much more you need to gain on the chassis side. Putting two and two together you can easily see what the performance is going to be."
Grosjean insists Lotus is still very much in the running for his services despite the frustrating year the team has had in 2014.
"They don't really have to convince me, I know what they are capable of doing. I know they have made good cars in the past and I know the struggle we have now since we are in the process of understanding what is not working very well between the wind-tunnel and the car and where we can improve. I know they are capable of making a good car if they have a budget they can work with that and if they get a good engine, which I believe, hopefully, they will. From there you can assess what they are capable of doing.
"I know the team is not going to do a season like this year next year because they will react and get better. Even though it's not going to be as good a car as last year it's hopefully going to be a car capable of fighting for points much more often, it can still be a good team."
Despite an association with Total, Renault's fuel supplier, Grosjean does not foresee an issue driving for a Mercedes-powered team next year - whether that is Lotus or not.
"There are things you can do about sponsorship. There are two Total's - Total Competiton, which is the sponsor which puts the sticker on the car, and then there is the Total company which is my sponsor. I'm on that side of Total company and I believe they would follow me wherever I go. Even to Mercedes. Last year for example I was ambassador for TAG Heuer but driving a car which had a Richard Mille sticker on it, so there are ways around it."
