American driver Alexander Rossi thanked Manor Racing for its support after losing his Formula 1 drive with the team on Thursday.
Rossi became the first American in eight years to race in an F1 grand prix when he replaced Roberto Merhi at Manor for five of the final seven rounds of the 2015 season.
Rossi made a positive impact in his short spell, matching the team’s best result of the year by finishing 12th in the United States Grand Prix, as well as finishing second in the GP2 Series drivers’ championship with three race wins for Racing Engineering.
Rossi had remained confident throughout the winter that he would be on the grid in 2016, but is now without a seat after Manor completed its line-up with Indonesia’s Rio Haryanto on Thursday.
Haryanto will form an all-rookie line-up alongside Mercedes junior driver Pascal Wehrlein, who joins by virtue of Manor’s new technical partnership with the German manufacturer.
Rossi took to Twitter shortly after Manor’s announcement to thank the team for its support, and said that positive news would soon follow.
“Thank you for your incredible support Manor Racing for the opportunities given,” Rossi wrote. “Positive news coming soon #StayTuned.”
Rossi had been in discussions with Dale Coyne Racing regarding an IndyCar seat at the beginning of 2015 before moving into GP2, and with a ride still open alongside Conor Daly for 2016, it could be an option once again.
Regardless, with the grid now set in Formula 1 for 2016, the wait for an American driver in the series will now resume.
