It is also the first four-cylinder engine by AMG to be specified with two outputs, assembled by hand using "one man, one engine" philosophy, and equipped with combined a port and direct fuel injection system.

[3] 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 two-stage fuel injection system, 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.
