Design

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 (for front-wheel drive models) while the M264 refers to the longitudinally mounted engine (for rear-wheel drive models).^[1] They use dual overhead camshafts 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. 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.^[3]
