Danica Patrick has refused to rule out entering formula one in 2016.
Gene Haas, F1's newest team owner, has said the world's most famous female racer "would be the dream driver" for his new foray.
He admitted, however, that the fact Nascar driver and American Patrick will be 34 by 2016 could be an issue.
"The question was about the dream driver!" Haas - who already runs Patrick in his Nascar team Stewart-Haas - told F1's official website.
"But she surely fits the bill."
Patrick told the Toronto Sun: "I agree that anything is possible, but nobody has said anything to me. I am happy where I am at right now as far as racing goes.
"I am just starting to get the hang of (Nascar) sprint cup racing.
"Out of respect for Gene, if he came to me I would certainly listen, but I am almost getting too old to start a third career," she added.
