Grosjean has been with the organization since 2016, and Magnussen joined the following year.
“The last chapter is closed and the book is finished,” Grosjean said in a team statement. “I’ve been with Haas F1 Team 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.”
Magnussen added, “The 2020 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 would like to thank Gene, Guenther and all of the race team for their loyalty and trust in me over the past four years. I am still working on my plans for the future, which I will announce in due course. There are still six races to do this season, and I am determined to give my all to finish off on a high.”
Replacements for Grosjean and Magnussen will be announced at a later date. Neither driver specified their plans past 2020.
