Porsche delays plans to introduce revised 963 LMDh engine
The decision to delay the update focused on a new crankshaft for the 963’s 4.6-litre twin-turbo V8 was made after discussions with WEC organizers, the FIA, the ACO, and IMSA in North America. The FIA and ACO demanded the engine be ready by the Imola WEC round in order to assess its performance. Porsche’s project chief Urs Kuratle stated that timing was insufficient for necessary endurance testing and for producing enough units. The timeline conflict with the Long Beach IMSA SportsCar Championship further complicated matters. The introduction of the latest LMDh hybrid system at Daytona eased Porsche’s reliability concerns. Kuratle mentioned that while engine revisions are still planned for this season, a specific timeline has yet to be determined.
