Peugeot has begun work on a replacement for its 908 turbodiesel Le Mans 24 Hours car.
Team manager Serge Saulnier has revealed that the French manufacturer is evaluating concepts for the 2011 LMP1 regulations.
A new car for 2010, the last year of the existing prototype engine formula, has already been ruled out by Peugeot Sport boss Olivier Quesnel.
Saulnier said: "We are starting to work on a 2011 car; we are beginning to think about the concept."
He suggested that Peugeot would remain in sports car racing beyond the life of the 908 coupe introduced in 2007.
"The management understands the need for consistency," said Saulnier, "but it is difficult to make a long-term plan at the present time."
He also explained that the state of the global economy would play a more significant role in the company's decision-making process than its result at Le Mans.
"That will decide the future, not our success at Le Mans this year," he said.
Peugeot's 908HY hybrid has not tested since its public airing last September.
