Speaking to NBCSN about his driver lineup, Haas said that Busch - who races for his Sprint Cup squad - was among several drivers who has expressed interest in the project.
And Haas, whose team will join the F1 grid in 2016 powered by Ferrari engines, added that he made the 2004 NASCAR champion an intriguing offer.
“Everybody I talk to is interested,” Haas said. “I was talking to Kurt Busch last week. He was interested. He said if he wins the NASCAR championship, could he have a ride in one? I said 'for sure!' if he wins the championship.
“I said he can get in the car!” continued Haas. “I tell you, an American driver in a Formula 1 car in Europe, that would just knock it out of the ball park.
“I’ll give it to you: Kurt Busch could drive one of these cars.”
“You know racers are racers,” he said. “I don’t think they’re really that much different to what we have in NASCAR, except everyone speaks different languages here."
At 36 Busch is already older than the entire 2014 F1 grid, making him an extremely long shot to race for the Haas squad. However a test is possible and, unlike most NASCAR drivers, Busch has recent single-seater experience having finished a strong sixth at this year's Indy 500.
