Ford doesn't fancy it. Neither does BMW. Toyota is also out. Formula 1's bold new era under new owner Liberty Media has begun with three of the world's major car manufacturers ruling themselves out of a return to the pinnacle of motorsport.
Mercedes, Renault and Ferrari are committed to F1 until at least 2020, with Honda insisting its project with McLaren is long term, but should new chief Chase Carey and co be concerned about the future?
American car giant Ford says the huge cost involved in an F1 programme is the main deterrent. It feels its presence in other series - GT racing, rallying and rallycross - is more relevant to its "goals and objectives" in "developing our tools, technology and people and translating that into road cars".
