A reliable run for the factory Porsche Penske Motorsport and customer entries at the Le Mans 24 Hours next month with the existing engine is likely to lead to a decision to leave the upgrade on the shelf, 963 project manager Urs Kuratle has revealed.
He explained that the improved durability of the 963 this year had largely removed the need for the new version of the engine, designed to reduce vibration in the name of reliability of the car’s hybrid system.
