Porsche's LMP1 management is set to undergo a restructure after technical director Alexander Hitzinger opts to step down to seek a new challenge away from motorsport.

After joining the Porsche board at the end of 2011 Hitzinger has helped the German manufacturer break into the World Endurance Championship and reach the ultimate high after claiming victory at Le Mans 24 Hours and win the world drivers', teams' and manufacturers' titles last year.

Fritz Enzinger, Porsche's vice president for its LMP1 operations, has thanked Hitzinger for his efforts over the past five years and his wished him well for the future.

"On behalf of Porsche I want to thank Alexander Hitzinger very much for his huge contribution to the outstanding successes of the Porsche 919 Hybrid," Enzinger said. "He was one of the first people to come on board at the end of 2011.

"I appreciate his desire for a new challenge. We are well prepared for the 2016 season. Within our team, which has a total of 260 employees, we also have a remarkably strong group of engineers working for the management team. The 2016 Porsche 919 Hybrid is ready to go."

Porsche has confirmed his successor will be decided in the coming weeks. The LMP1 squad begins its 2016 season on 25th March at Paul Ricard for the WEC Prologue.
