Bernie Ecclestone's latest plan is for a grand prix to be hosted in Las Vegas on the world-famous strip.
Although a race in New Jersey has fallen through in the past two years, Ecclestone has successfully expanded the calendar to Austria and Russia this year and 2015 will see the return of Mexico before a street race in Azerbaijan's capital Baku in 2016. He said Las Vegas is now pushing for its own grand prix.
"Vegas say they are ready to go and it would be on The Strip for sure," Ecclestone told The Independent.
In 1981 and 1982 F1 races took place in the car park of the Caesars Palace hotel in Las Vegas, but the on-track action was far from popular due to the uninspiring track layout. Ecclestone says Las Vegas is not alone in wanting to host an F1 race in the future.
"In the end there's a million countries that would like to have an F1 race but they can't afford it."
However, with Formula One's calendar already at bursting point, it is not yet clear how all the proposed new races will fit in the future.
"It is more likely that it will go over 20 with Baku than we lose a race," Ecclestone added.
