Mazepin was runner-up in GP3 in 2018 with ART Grand Prix before stepping up to F2 with the same team for 2019. After an unsuccessful rookie year he moved to the Hitech Grand Prix F2 team and currently sits in third place in the drivers' championship, having won two feature races and collected six podiums, still in with a shout of the title.
Haas Team Principal Guenther Steiner said: “Nikita has underlined his credentials in Formula 2 this year with a brace of victories and a handful of podiums in what’s been a strong sophomore season for him.
“I’m excited to see what Nikita can achieve in Formula 1 and we look forward to giving him the opportunity to compete at the highest level of world motorsport.”
While no announcement has been made about Grosjean's plans for 2021, Magnussen recently announced a switch to sportscar racing, joining Cadillac's efforts in the IMSA Weathertech Sportscar Championship.
