Chronology
Predecessor Mercedes-Benz M270/M274 engine

The M260 and M264 are turbocharged inline-four engines produced by Mercedes-Benz since 2017. It is the successor to the M270 and M274 engine.

Design

Both engines are based upon the same modular design, however M260 refers to the transverse configuration (for front-wheel drive models) while M264 refers to the longitudinally mounted engine (for rear-wheel drive models).[1] They use a dual overhead camshaft with 4 valves per cylinder, feature twin-scroll turbochargers,[2] and have particulate filters installed. M264 engines also have intake variable valve timing and a 48V system that powers the electric auxiliary compressor and integrated starter alternator.[3]
