New Formula 1 managing director of motorsports, Ross Brawn, says he would like to see a better quality of event on the calendar, but hasn't ruled out expanding the calendar beyond the current 20-race schedule.
The Formula 1 calendar has seen new multiple new additions over the past decade, boosting it to a record-21 rounds last year, driven by additions such as Singapore, Azerbaijan, Russia and Abu Dhabi.
An expanded calendar helps to drive Formula 1's profits, but Brawn believes the sport must race in "exciting places", rather than adding races merely for the sake of exploring new territories.
"We've got to make sure we don't just have races because we can increase the number, the races have to be of good quality, in good places and in exciting places," he told ESPN.
"We also need to think about the frequency of races because the nice balance of a race every other weekend is perfect."
However Brawn wouldn't rule out expanding the calendar, though he knows that would require change within the teams to cope with the extra demands.
"Teams can organise themselves to do more than the current number," he added. "There is absolutely no reason why we shouldn't have more races, but you can't have more races with the same structure that teams have now, because it would just break it.
"20 or 21 [races] is pretty tough on the crews and tough on the engineers, tough on everyone who travels. But if you then set yourself up with two sets of crews and two sets of engineers and all the rest of it, which I believe is what NASCAR does, then you can do it.
"If we can have more races and find a way with the teams of giving them the capacity to do it properly then it's certainly not a strain on the drivers, because they don't do any testing anymore.
"Fundamentally we need to decide if we want that number of races and if it makes sense for the sport and makes sense for the show."
