Nico Rosberg has hinted he will stay at Mercedes beyond his current contract.
Recent reports said the German has been offered a new deal to keep him at the team for at least four more years.
"Nico and Mercedes are interested in a very long term cooperation," admitted Norbert Haug.
The 26-year-old driver told FAZ newspaper in Singapore: "We are currently discussing that."
Also on the cards is a new contract for Rosberg's current teammate Michael Schumacher, whose current deal is also set to expire at the end of 2012.
Rosberg said the structure with "two leaders" in the cockpits is working well.
"Both drivers are on the same level, so that even if I'm faster there is always a corner in which he is faster, or a setup that he understands better.

"So you are always learning something. I'm very open, very interested in trying to pick up all the little pieces that you need. We clearly both benefit," said the German.
His real goal, of course, is to be the number one.
"Of course, to be the most successful driver in the team is the only way I can win the races to become world champion," said Rosberg. "It's up to me to get into that position."
