At one stage it appeared the United States' appetite for F1 was insatiable.

Despite Watkins Glen's long association coming to an end in 1981, the following season there were an unprecedented three American races, as Detroit, Las Vegas and Long Beach all welcomed the sport.

Though that particular hat-trick lasted just one season, Formula One supremo Bernie Ecclestone is keen for a return to the glory days and is desperate to add a second U.S. race to the modern-day roster.

New Jersey had been included on a provisional 2013 calendar but organizers have been forced to postpone for a year as they continue to grapple with financial issues.

Ecclestone has long pined for a grand prix in the picturesque city of New York, but whether a second race appears in the Big Apple or in neighboring New Jersey, Andretti is confident the U.S has a sufficient appetite for two visits a season.

"America as large as it is can easily support two races -- one would feed off the other," he explained.

"I just can't see a negative in any way. I know Bernie Ecclestone for many years has wanted to have something in the proximity of New York for obvious reasons.

"And with the event there and the backdrop of Manhattan, it's going to provide the ambience they're looking for. I think both venues could be very attractive."
