Romain Grosjean has announced that he will be leaving the Haas Formula 1 team at the end of the 2020 season.

Grosjean, who has been an ever-present in Haas’ line-up since it entered F1 in 2016 and contested 94 races for Haas, will depart the team after five years.

It leaves Grosjean without a drive and facing the prospect of having just six more races in F1.

“The last chapter is closed and the book is finished,” Grosjean wrote in a post on social wrote.

“I've been with Haas F1 Team since day 1. Five years during which we went through highs and lows, scored 110 points in 92 races, but the journey was worth it.

“I've learned a lot, improved to be a better driver as well as a better man. I hope I’ve also helped people in the team to improve themself.

“This is probably my biggest pride, more than any of the crazy first races in 2016 or the P4 at the Austrian GP 2018.

“I wish the team all the best for the future.”

Haas is yet to officially announce Grosjean’s departure, nor has it confirmed who will be replacing the Frenchman for 2021.

Teammate Kevin Magnussen’s future is also uncertain, with the Dane out-of-contract at the end of the year amid mounting speculation that he too could lose his seat at the American outfit.

Haas appears set to completely overhaul its line-up for 2021, with Ferrari junior and current Formula 2 championship leader Mick Schumacher and fellow F2 rival Nikita Mazepin both linked to the team.
