A hybrid Porsche 911 will race at the Nurburgring 24 Hours this year, and could form the basis of a car for a return to Le Mans with an LMP1 prototype.
Reports suggest the Porsche 911 GT3-RSR is being prepared to run as a petrol-electric hybrid, using an F1-style KERS system.
Porsche has refused to comment on the car, but an announcement is expected later this week.
“It is not a question of yes or no, but a question of how and when," said Porsche motorsport boss Hartmut Kristen when asked about its hybrid intentions.
“We believe that the future of motorsport is not only with the conventional internal-combustion engine,” he added. “We have to think about the alternatives. When you see the red-hot discs on a racing car, you have to think about all the energy being wasted.”
Porsche has already committed to selling hybrid versions of its Cayenne and Panamera road cars.
