14-463: A first in AMG four-cylinder engine, has the piezo injectors delivering the fuel directly into the combustion chambers as first stage and solenoid valves in the manifolds as second stage for increased specific output. An electrically assisted turbocharger system by Garrett Motion is used. The M139 engine has two specific outputs: 285 kW (387 PS; 382 hp) and 480 N⋅m (354 lb⋅ft) for
21-508: A port and direct fuel injection system. At 310 kW (416 hp) on its introduction, M139 was the world's most powerful four-cylinder engine in serial production with specific output of 155 kW (208 hp) per litre or 78 kW (104 hp) per cylinder. The current top trim of the M139 produces 350 kW (469 hp), giving it a specific output of 175 kW (235 hp) per litre or 87.5 kW (117 hp) per cylinder, making it

Unlike the normal M260, the AMG engineers rotated the engine block 180 degrees so that the intake system is in the front of the engine, while the turbochargers and exhaust headers are situated between
42-479: The engine and firewall. The rotation optimises the engine air flow for higher performance and with shorter distance and fewer diversions. This also "allows the flattest possible and aerodynamically advantageous front section design." The exhaust valves in M139 engine are bigger than ones in M133 engines for higher flow. The compression ratio is raised to 9.0:1 for M139 from 8.6:1 for M133. The two-stage fuel injection system,
