The Gibson GK428 engine is a 4.2-litre normally-aspirated DOHC V8 engine. It has been developed and produced by Gibson Technology for sports car racing since 2017.[3][4]
Development
The engine had been in development since August 2015, prior to being selected as the sole engine supplier for all of the new 2017 regulation LMP2 cars.[5] It shares some architecture with the Zytek ZG348 engine, which previously powered multiple LMP2 cars.[6] The engine has a target for the running costs of about $1,400 per hour, which was tested to last for 50 hours or 8,000 km (5,000 mi) on average.[6][7] During the 2024 4 Hours of Mugello, the engine reached 5,000,000 km (3,106,856 mi) of running since it was introduced.[8]
