Formula 1 CEO Chase Carey says the sport’s calendar is “full” and Liberty Media’s new races will be added as current rounds drop from the schedule.

The 2019 F1 calendar has not yet been announced but three of this year’s races do not have contracts for next season.

Speaking exclusively to RaceFans at the FIA Sport Conference in Manila, Carey indicated there are “three or four” races per season whose contracts will expire over the next few years. Those which drop off the schedule could be replaced by races at new venues.

“Ideally we want our relationships to be long-term partnerships,” Carey explained. “That being the said it’s a reality of life that there are changes.

“We expect there continue to be a limited level of change per year but that opens up opportunities to bring in some new races that we thing would really be exciting new platforms for fans and for the sport.”

“We’ve got a full calendar,” Carey added. “Our focus really is quality not quantity.”

While the proposed Miami grand prix is the only likely new race for next year, Carey said further additions are possible for subsequent seasons.

“For ’19, it’s getting pretty well-baked. As you get out to ’20, ’21, there’s certainly discussions we’re having which could lead to new races.”

The sport’s management is “quite excited about the degree of interest from places round the world” in holding F1 grands prix, according to Carey.

“We have interest from locations in Africa, South America, the US, Europe. While we have a pretty full slate of European races this year, we have places in Europe that want races.

“We’ve got places that want to have races that probably wouldn’t work for us. But we’ve got a large number of places that would be interesting and we’re in discussions and we’ll see where those discussions take us.”
