Romain Grosjean on Thursday said he has made his decision about what team to drive for in 2016.
The Frenchman currently drives for Lotus, the cash-strapped team whose very survival may depend on whether Renault decides to buy it.
Grosjean has also been linked with a switch to Haas, the new Ferrari B-team, with some reports saying the American outfit may now have decided to pair the 29-year-old with Ferrari reserve Jean-Eric Vergne.
"The only thing I can tell you is that I have made my decision," Grosjean told reporters in Singapore when asked about his future.
"Everything is clear in my head and I know what is going to happen for me in the future. But that is in my mind and I won’t tell you anymore," he insisted.
