Speaking to media on the eve of the Singapore Grand Prix weekend Romain Grosjean revealed that he has made his decision about what Formula 1 team to drive for in 2016, but cannot speak about it as yet.
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.
Grosjean will be starting his 77th grand prix when he lines up on the grid in Singapore, having scored 10 podiums thus far in his career although a F1 victory still eludes him.
He made his F1 debut at the 2009 European Grand Prix for Renault alongside Fernando Alonso. But the move was too much too soon for Grosjean, whose cause was not helped as the Enstone outfit was reeling from 'Crashgate' revelations at the time.
Dropping out of Formula 1 at the end of 2011, he tried his hand at FIA GT Championship, including Le Mans and returned to GP2 Series in 2011 - winning the title that year.
He was drafted into the Lotus team in 2012 and at first gained notoriety for being a 'first lap nutcase' and triggered a huge accident at the Belgian Grand Prix that year and was banned for a race.
Since then Grosjean has matured and had a sensational season in 2013, establishing himself as a potential front-line driver and earning the respect of the F1 community.
