Circuit of the Americas chairman Bobby Epstein firmly believes the United States Grand Prix can survive financially at the venue.

It had been suggested in the build up to Sunday’s race at the Austin track that COTA was struggling to make ends meet.

Despite being a roaring success with teams, drivers and fans over the three years since its debut on the calendar, there are still bills to be paid.

Notably, Formula One supremo Bernie Ecclestone’s race-sanctioning fee – understood to be around $20 million – is always a major headache for promoters.

Although times would appear to be tough for Epstein, he said: “If this is going to be profitable for the investors, then we have to rely on other things that happen.

“We had around 200 events last year, but that includes a lot of track rentals, a lot of manufacturers’ product launches.

“Overall, we’ve a long-term mutual commitment, and we’ve a business model that can sustain that, so we plan for it (the race) to be here for quite a while.

“Texas likes what they are seeing. Having them as a partner is an absolute must.”
