Now, rumours of a change of venue have emerged.
"In Brazil, the economic situation is very strong," Indycar driver Helio Castroneves, whose category will race on the Sao Paulo streets in May, said last week.
"I heard now that formula one might move from Sao Paulo to the south of Brazil. Obviously it's all about how much the promoters are willing to spend.
"I think it's more than just interest," the Penske driver added.
