Porsche has reported that its LMDh prototype is showing positive progress following its first four months of track testing.
Testing has been underway at Porsche’s development site in Weissach (Germany) and on the European circuits of Barcelona and Aragon in Spain and Spa-Francorchamps in Belgium, clocking up over 6000km of running.
This distance corresponds almost exactly to that covered by the fastest prototypes in the IMSA series (DPi class) during an entire Daytona 24-hour race event – including all practice sessions and official tests (the three-day ‘Roar before the 24’) as well as the 100-minute qualifying run and the legendary 24-hour race.
According to Porsche, the focus of the test work to date has been on function checks, the optimization of the interaction between the V8 biturbo internal combustion engine and hybrid components, and development work with tire partner Michelin.
As the program progresses, Porsche will likely want to complete at least one trouble-free 30-hour endurance test prior to the car’s debut at the start of 2023.
