And amid rumours Lewis Hamilton could switch to the Brackley based camp for 2013, Brawn has told the Daily Mail he is not going anywhere for now.
"I am not planning to retire at the moment," he said.
Also being reported at present is that Michael Schumacher could be close to signing a new at least one-year contract extension for 2013.
Brawn said he is motivated by F1's switch to radical new engine rules in 2014.
"I am very excited about this 2014 engine programme," he said. "I think it is quite a game-changer in F1.
"I still have a strong engineering passion, so having such a different engine and different package in 2014 is exciting and developing the team is exciting.
"For how long, who knows? But I have no interest in stopping in the near future."
