Kevin Magnussen will contest neither the Daytona nor Le Mans sports car races next year.
It had been reported that the Haas driver was in talks about taking part in the Daytona 24 hour race in January, on the same track as fellow F1 drivers Fernando Alonso and Lance Stroll.
Magnussen told Danish newspaper BT: "There was some talks with a team, but for a variety of reasons there is no deal. It will have to be another time.
"There's also no chance that I will do Le Mans this year."
Magnussen finished 14th in the 2017 drivers' championship.
