Could Manhattan host a Grand Prix in the future?

"I'm talking to some people in New York - that would be nice," Ecclestone said at Sunday's United States Grand Prix.

Ecclestone has already announced that the US race will stay at Indianapolis for at least the next two years.

Ecclestone is reported also to be talking about reviving a Grand Prix at Long Beach in California.

Indy to extent F1 contract

The Indianapolis Star newspaper said that Ecclestone has been talking to Long Beach Grand Prix promotor Chris Pook about a return for the race.

F1 staged a very popular race at Long Beach from 1976-83, before it switched to the US Champ Car series.

Ecclestone is keen to raise F1's profile in the USA, a very important market where it has traditionally struggled to gain a foothold.

After the demise of Long Beach, a number of different venues were tried out without success before the race dropped off the schedule after 1991.

Ecclestone hopes Indianapolis will be a permanent home for F1 in the US, regardless of whether he can add another race in the country.

"It's great to be here, and yes, I think it's very important to be in America," Ecclestone said.
