Romain Grosjean and Kevin Magnussen will be leaving Haas at the end of the season.
The Formula One team made the announcement on Thursday morning, ahead of this weekend’s Portuguese Grand Prix.
Haas’ team principal Guenther Steiner, said: “I want to extend my thanks to both Romain (Grosjean) and Kevin (Magnussen) for their hard work and commitment to Haas F1 Team over the past few seasons.
“Of course, there is still plenty of racing left in the 2020 season. It’s been a challenging year, no doubt about that, but both drivers have given their all behind the wheel of the VF-20. We value their inputs and experience to keep pushing the team forward through to the Abu Dhabi Grand Prix in December.”
Grosjean, 34, has been with the American team since they entered Formula One in 2016 and has made 175 starts but the concluding six races of the season are set to be his last in the sport.
“The last chapter is closed and the book is finished,” said the Frenchman in a Facebook post ahead.
“I’ve been with Haas since day one. 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 themselves. This is probably my biggest pride, more than any of the crazy first races in 2016 or fourth at the Austrian GP 2018. I wish the team all the best for the future.”
Magnussen also took to social media following confirmation of the news.
The Dane told Twitter: “The 2020 Formula 1 season will be my last with Haas F1 team.
“I have had a great time with the team for four years and I look back at a great journey.
“Being part of a brand new team has been a challenge that I have thoroughly enjoyed and it has brought me a huge amount of experience that has helped me grow and develop as a racing driver.
“I am still working on my plans for the future, which I will announce in due course.
“There are still six races this season and I am determined to give my all to finish off on a high. Thank you all for your support.”
