Design

Due to Daimler AG's collaboration with the Renault–Nissan–Mitsubishi Alliance, the OM608 is heavily based on the Renault K9K engine.^[2] It features common rail direct injection with 2 valves per cylinder, and a cast iron engine block and crankcase with an aluminium alloy cylinder head.^[3] Differences include the engine control unit (ECU), a stop start engine system, a dual-mass flywheel, and the ancillaries.^[4]
