Formula One wants to keep the Brazilian Grand Prix on the calendar but where South America’s only race will be held after 2020, when the contract with Sao Paulo ends, remains uncertain.

Formula One chairman Chase Carey, who represents US-based commercial rights holders Liberty Media Corp, told reporters at last weekend’s race at Interlagos that all options were being evaluated.

“We have interests, we have multiple partners that are interested,” Carey said. “It is certainly our goal to continue to race in Brazil for a long time.”

Interlagos is confirmed for 2020, but Rio de Janeiro is a candidate for the year after.

Sao Paulo wants to keep the race and state governor Joao Doria said there will be a meeting with Liberty in the first week of December, when a formal proposal will be presented by the city.

Sao Paulo currently pays no fee to F1, unlike others around the world who pay as much as $US66.35 million ($A97.36 million) for their races, but Doria said that would change.

“We are going to pay the fee in the next contract, we will have private money coming in, private investments as well,” said the governor.

The city of Sao Paulo, governed by Doria’s ally Bruno Covas, is set to sell the rights to manage Interlagos for 33 years to the private sector on January 8.

The plan is to have activities all year round in the circuit’s area, as well as to build a hotel, exposition area and possibly a shopping mall.

There were talks during the weekend about other locations, in smaller cities outside the Rio-Sao Paulo axis.
