F1's new chairman Chase Carey has been open in admitting that expansion in America as one of the things that he is interested in pursuing.

But Brown, who is hotly tipped to take on an F1 sponsorship/commercial role in the near future, believes that the plans could come to fruition by 2019.

"It's got to be a priority," Brown told Motorsport.com about plans for a second United States GP.

"It takes some time, so I don't think we'll see it in 2017 or 2018, but I'd like to think that in 2019 or 2020 we'd see a second American race on the calendar."

Brown thinks the sport's impact in the USA will increase in the next few years, although not simply because Liberty Media are American.

"I don't think it'll raise F1's profile because it's owners are American, I think F1's profile will be raised in America because that'll be a big, geographic focus," he said. "It's an obvious territory. It's the biggest and most mature sports market – therefore it's got to be on F1's radar.

"When they went through the strategy, they already mentioned how important the European circuits are, but of course North America is important as a whole. And they know that marketplace so well.

"I think it's nothing but a good thing – I think they'll give it a lot of time and attention."

Mexican support

Mexican GP organisers have also expressed their support for the idea of more races in the Unites States, because they think it will be a boost to all races on that side of the world.

Mexican Grand Prix marketing director Rodrigo Sanchez told Reuters: "When we are trying to build new audiences and bring new fans and create a new fan base, it does get a little complicated.

"We wish we could have more and more races on prime time on our side of the world and I think the only way we will get that is if, collaboratively, there start being more races in the region in general.

"It would be great to basically consolidate Formula 1 in North America."
