Formula 1 commercial rights manager Bernie Ecclestone has admitted that Austin Grand Prix officials are facing an "uphill struggle" with their preparation for next year's race, but he remains hopeful that the race will take place.
Ecclestone told team principals in India two weeks ago that he had some concerns about the race's prospects, and he later confirmed to the media that there was an issue with the promoting company. Speaking to reporters at the Abu Dhabi Grand Prix, Ecclestone reiterated his worries about the situation in Austin.
"We are trying," he said. "It is a bit of an uphill struggle but we will try and get there.
"There are two parties. One has got a track and is building it, and the other has got the contract. And they forgot to talk to each other."
When asked if the race was becoming more doubtful, Ecclestone said: "I think not. They want it to happen, they will sort it out."
Ecclestone added that a possible return of the Turkish GP next season, should one of the planned races not happen, was unlikely.
"I doubt it, but you never know," he said. "I didn't want to lose it, so we are trying with the government again to see."
