mercedes-benz m264

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.
Both engines are based upon the outgoing M270 and the M274 respectively. Like the M270 and the M274, the M260 refers to the transverse configuration while the M264 refers to the longitudinally mounted engine. They use dual overhead camshafts with 4 valves per cylinder, feature twin-scroll turbochargers, 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. However, unlike M256 which uses a BorgWarner electric auxiliary compressor, the M264 has a belt-driven starter-alternator combo as well as a 48V electric water pump....
