does not think multi-millionaire NASCAR team owner Gene Haas can afford to enter Formula 1 in 2015.

Haas, with an estimated net worth of $740 million, announced recently that he has responded to the FIA’s ‘call for expressions of interest’ in filling the vacant slot in pit lane.

Haas co-owns the NASCAR team Stewart-Haas Racing and heads one of the best wind tunnels in the world. According to Auto Motor und Sport, he would start in Formula 1 with a healthy three-digit million budget.

But Formula 1 chief executive Ecclestone told Racer he thinks it is “most unlikely” Haas will enter Formula 1 because of the sport’s huge costs.

“They (Haas) have been talking about it for three years,” Formula 1 business journalist Caroline Reid quoted Ecclestone as saying. “Somebody can have 10 billion in the bank but it doesn’t mean they are going to spend it.”
