Brazil is known to be an attractive location for the all-electric championship and could run as a back-to-back with the Buenos Aires ePrix, which traditionally runs in January/February.

"It is a priority to run in Brazil," Agag told Brazilian magazine Grande Premio.

"We are in talks with a number of potential host cities at the moment. I think it's very possible to see us running in Brazil maybe next season, or more likely in the fifth season."

Last season's runner-up Lucas di Grassi has been pushing to have a home race on the calendar, and presented a possible circuit layout in the Ibirapuera Park area of Sao Paulo to series officials.

Ibirapuera is one of Latin America's biggest parks, and a popular location for sports in Sao Paulo. The layout of the track that di Grassi proposes would race around the park's main lake (pictured above).

"I have drawn out a track and now we try to make something happen," di Grassi told Motorsport.com.

"The prospects are exciting not only for me but also the race fans of Brazil, it would be a great highlight for me to be able to race in my home city again."

While the Ibirapuera location is one of several under consideration, a Brazilian ePrix is more likely only for the early months of 2019, when the championship will have started its fifth season.

2017/18 calendar could start in December

Meanwhile, Formula E's fourth season could start as late as December, with Hong Kong remaining the series' favoured option for the opening round.

The electric single-seater series' 2016/17 schedule was compromised when it locked its Hong Kong curtain-raiser into an early October slot.

It added a race in Marrakech at the start of November, but could not fill a three-month break between rounds two and three that comes to an end next month in Buenos Aires.

"We won't be racing in Hong Kong in October again," Agag told Motorsport.com's sister title Autosport.

"We want Hong Kong [as the opening round], we're looking at delaying it until late November or even the first weekend of December.

"And then we'll pack the calendar much more, with much more racing in January and February. Formula 1 and the other championships are going up to November, so December may fit well."
