The Mercedes-Benz M113 (and similar M155) engine is a petrol-fueled, spark-ignition internal-combustion V8 automobile engine family used in the 2000s. It is based on the similar M112 V6 introduced in 1997, then later phased out in 2007 for the M156 AMG engine and the M273 engine.
The standard Mercedes-Benz M113s were built in Untertürkheim, Germany, while the AMG versions were assembled at AMG's Affalterbach, Germany plant. M113s have aluminum/silicon (Alusil) engine blocks and aluminum SOHC cylinder heads with two spark plugs per cylinder. The cylinder heads have 3 valves per cylinder (two intake, one exhaust). Other features include sequential fuel injection, iron coated piston skirts, fracture-split forged steel connecting rods, a one-piece cast camshaft, and a magnesium intake manifold.

E55K AMG
The M113 Kompressor is a supercharged and twin-intercooled version of the {{convert|5439|cc|L|1|abbr=on|order=flip}} M113. It is commonly referred to as "M113K" – where 'K' stands for Kompressor (supercharger). Power output varies depending on year and model, from {{convert|469|bhp|PS kW|0|abbr=on}} at 6,100 rpm for the E 55 AMG to {{convert|574|bhp|PS kW|0|abbr=on}} in the 2004–2006 CLK DTM AMG, with {{convert|700|to|800|Nm|lbft|0|abbr=on}} of torque at 2,750–4,000 rpm.
Many Mercedes-AMG enthusiasts consider the M113K as the last of the great Kompressor engines used by Mercedes-AMG excluding the Mercedes SLR McLaren. The M113K engine has also received praise for its reliability. Mercedes-AMG replaced this model with their new 6.2 L naturally aspirated V8, making the transition from 55 AMG to the 63 AMG.
