Porsche will test new components next week designed to address the problems that put Mark Webber’s Porsche 919 Hybrid out of contention in the Spa World Endurance Championship race.
The #20 Porsche, shared by Webber, Timo Bernhard and Brendon Hartley, finished 23 laps down on the winning Toyota TS040 Hybrid in 23rd place after the front right driveshaft had to be replaced on two occasions.
Porsche LMP1 technical director Alex Hitzinger has revealed that the same problem had already been encountered in pre-season testing and that a stronger driveshaft was already in manufacturer ahead of Spa.
The new components will be tested when Porsche undertakes its second and final endurance simulation before the Le Mans 24 Hours in June at the Aragon circuit in Spain next week.
“We already have stronger parts in the pipeline and we will have them when we test next week,” Hitzinger said.
The hybrid system problem that lost the fourth-placed #14 Porsche 919 driven by Neel Jani, Marc Lieb and Romain Dumas was a result of a false system alarm, according to Hitzinger.
“We are very conservative on our alarms and this time we were too conservative,” he admitted.
Dumas had to cycle through the car’s electronic systems to cure the problem, which lost Porsche any chance of finishing on the podium.
Porsche has so far chosen not to reveal the nature of the driveline failure that put the #14 car out of the WEC opener at Silverstone last month.
