Kevin Magnussen has revealed there are only two options that would tempt him into a return to F1 - Mercedes or Red Bull.
Magnussen raced in F1 for six years between 2014 and 2020, initially with McLaren, and then after a season on the sidelines, a year with Renault followed by four with Haas.
After parting company with Haas at the end of last season, the Dane now competes in sportscars in the United States, claiming his maiden victory on Saturday in Detroit with Cadillac Chip Ganassi Racing.
Asked by Autoweek if he would consider rejoining the F1 grid again, he said: "If I had a Mercedes or a Red Bull I wouldn't say no. I don't think many racing drivers would, but that's not going to happen.
"As I said before, I'm very, very happy with the opportunity that I had in Formula 1. Not many people get to have that many years in Formula 1.
"I'm super happy about that and I had some great experiences. Having said that, I feel fresh motivation, and I feel like it's fun again."
Magnussen 'feels' for Haas
Despite a promising start to his time with Haas, results dwindled in the final two years with a team that opted for a change in driver line-up by bringing in rookie pairing Mick Schumacher and Nikita Mazepin.
The young drivers are competing in an uncompetitive car that is not being developed as Haas focuses on the dramatic changes to next year's regulations.
Magnussen has offered his sympathy to all at Haas. He said: "I feel for them. They're great people. I have many friends and they're kind of like family to me so, I feel for them.
"But I'm sure it's going to get better for them when these new rules come in. There will be a reset of basically all the teams.
"Of course, it's still going to be the big teams at the front, but I hope it's going to be a little closer."
