Engine Specification

About the Mercedes-AMG 113.990 Engine

The Mercedes-AMG M113K — engine code 113.990 — is the supercharged variant of AMG’s 5.4-litre V8, distinguished from the naturally aspirated M113 by the addition of an IHI Roots-type positive displacement superchargermounted between the cylinder banks. This supercharger delivers immediate, lag-free boost from idle, giving the engine its characteristically effortless, linear power delivery — producing 700 Nm of torque available from as low as 2,650 rpm — that made the E55, CLS55, S55, and CL55 AMG among the fastest and most capable performance saloons and grand tourers of their era.

The M113K is a hand-built AMG engine — assembled at Affalterbach with the precision and accountability of AMG’s one-man-one-engine philosophy — and is regarded as one of the great naturally charismatic performance engines of the modern AMG era. Its character — the supercharger whine under hard acceleration, the instant throttle response, and the deep V8 soundtrack — has made the E55 and CLS55 AMG in particular enduring enthusiast favourites that continue to appreciate as the values of well-maintained examples rise.

At 134,689 kilometres, this engine is at a realistic mid-life stage for the M113K platform — a durable architecture when properly maintained with regular oil changes and attention to the supercharger oil change interval. For owners replacing a higher-mileage or failed unit, this example provides meaningful remaining service life at a practical cost relative to a full rebuild.
