IndyCar officials have confirmed that the series is exploring the possibility of returning to Brazil, and is currently in discussions with event organisers in the capital city of Bras?lia regarding a race in 2015.

If confirmed, the race would staged at the 3.403-mile, 12-turn Autodromo Nelson Piquet permanent road course in the capital city of Bras?lia, which is also expected to host a MotoGP race in 2015.

The last time a round of the newly-renamed Verizon IndyCar Series took place in the South American country was 2013, when the last of three races on the streets of S?o Paulo - the Itaipava Sao Paulo Indy 300 - was won by Canada's James Hinchcliffe.

"Brazil has a real history in Indycar racing and we would like to re-establish a championship race there as early as 2015," Mark Miles, CEO of series parent Hulman & Co, confirmed, "We are engaged in on-going discussions toward this goal and hope suitable arrangements can be finalised soon.

"There is still a lot of work to be done, but we are encouraged by the efforts from the Government of the Federal District - GDF - and the governor of Brasilia Agnelo Queiroz, as well as the TV Bandeirantes Group.

"We look forward to continuing these discussions as IndyCar explores race markets and venues that will further the growth of the Verizon IndyCar Series."

The 2014 Verizon IndyCar Series opens over the weekend of 30 March with the Firestone Grand Prix of St Petersburg.

Early reports have suggested that the new Brazil event could be held as early as March 8 in 2015, which could make it next year's season opener.

"I'm very happy to find out that our return to the calendar is secured," said three-time Indianapolis 500 winner Helio Castroneves in a statement.

"It will be great to race in Brasilia and I can't wait for that to happen. Several challenges kept Brazil from hosting the race in 2014, but that's life. Sometimes we need a step backward to come back stronger."
