Grosjean, Alonso and Hamilton want more US races

Formula One drivers Romain Grosjean, Lewis Hamilton and Fernando Alonso have called for more races in the United States in the future.

At the moment, America only hosts one F1 event a season with the race being held at the Circuit of the Americas - last Sunday being the most recent.

In the past, there have been numerous races held in America, with venues including Watkins Glen, Phoenix, Las Vegas and Indianapolis Motor Speedway.

There are negotiations ongoing about a possible race being held in Miami as early as 2020 and that is a popular wish for many of the leading forces of the sport.

"To me, the obvious answer is to get more races in the U.S," Grosjean, who drives for American outfit Haas insisted. 

Grosjean said that adding more F1 races will only help its popularity and wealth grow in the country.

"It's not easy to grow the fan base," Grosjean said. "Most of the time it's really hard for the audience to watch the Grands Prix (because) it's the middle of the night."

Hamilton echoes Grosjean's words about America: "We do have the one race and this is a big, big country with a lot of sporting heritage. (But) we only have that one race here. 

"So the people; for example, in this city or people in the close States that fly over for this one Grand Prix, which happens once a year; it's like a festival. You can't really get too excited about one festival in a season."

Alonso, who is retiring from the sport at the end of the season, has demanded owners Liberty Media to set up more races in the U.S: "Get more races here, hopefully one American driver into F1 soon, and that will help.

"It will take a little bit of interest into the sport and have a little bit more unpredictable race. Have people expecting the unexpected until the end."
