Porsche will return to the works strategy that netted victory at Le Mans with this 911 GT1 in 1998.
Porsche will revive its in-house factory team for its return to the prototype ranks in 2014.
The German manufacturer's forthcoming LMP1 hybrid will be run by a full works team based at its Weissach research and development headquarters. This facility near Stuttgart is where Porsche's first outright contender for Le Mans 24 Hours honors since 1998 is being designed, developed and built.
Porsche R&D boss Wolfgang Hatz made the announcement at Porsche's Night of Champions awards ceremony on Saturday evening.
Porsche has upgraded its motorsport facility since its last major program with the RS Spyder LMP2, which was run by Penske Racing on behalf of Porsche in the American Le Mans Series and by customer teams in Europe.
It is understood that approximately 200 people are working on the P1 project. Hatz said that the new Porsche LMP1 is due to run in the middle of next year.
The only other news on the project was the confirmation of a restructuring of Porsche Motorsport, with former BMW man Fritz Enzinger taking control of the P1 project and head of motorsport Hartmut Kristen retaining control of the manufacturer's 911-based programs.
The majority of Porsche's 16 Le Mans wins have come with teams run direct from the factory. That number includes its final victory with the 911 GT1-98 14 years ago.
Porsche will run a factory team for the first time since 1998 in next year's FIA World Endurance Championship as it develops its new 991-shape 911 RSR GTE contender. The car will be run in conjunction with Manthey Racing under the Porsche AG Team Manthey banner.
