Mercedes-Benz M113E55 ML AMG 5.5L V8 Petrol Engine

Legendary AMG-engineered Powerplant, used engine For Sale.

The Mercedes-AMG M113E55 5.5L V8 Engine is a legendary AMG-engine powerplant for its exceptional durability, massive torque output, and unmistakable performance character. 

Built on the highly respected M113 platform, this engine features a 90-degree V8 configuration, with a Single Overhead Camshaft (SOHC) per cylinder bank and a 3-valve-per-cylinder layout (two intake, one exhaust).

 This proven design prioritizes mechanical strength and long-term reliability while delivering the aggressive performance expected from an AMG engine, making it a premium choice in the second-hand engine market.

With a displacement of 5.5L (5,439 cc), the M113E55 however is an AMG Kompressor (supercharger) system that dramatically enhances power and low-end torque. Output typically ranges between 469–500 horsepower and approximately 700 Nm of torque, depending on application and tuning. 

The supercharger ensures instant throttle response and effortless acceleration, while the all-aluminum block and cylinder heads help reduce weight without sacrificing structural integrity. Unlike more complex multi-cam engines, the SOHC and 3-valve configuration contributes to excellent reliability and easier servicing.

The M113E55 AMG engine was fitted across several high-performance Mercedes-Benz models, most notably the ML55 AMG (W163). It was also used in iconic AMG models such as the E55 AMG (W211), S55 AMG (W220), SL55 AMG (R230), and CL55 AMG, making it widely compatible across luxury sedans, coupes, and SUVs.

 Its ability to pair with heavy-duty automatic transmissions and all-wheel-drive systems further increases its versatility as a replacement or performance upgrade engine.

 Specifications, Common weaknesses and Maintenance.

While the M113E55 has an excellent reputation, some common weaknesses may appear with age or high mileage. These include oil leaks from valve cover and oil cooler seals, supercharger clutch or bearing wear, aging cooling system components, and worn engine mounts. Ignition coil failures may also occur over time but are generally straightforward to address.

Maintenance notes emphasize routine high-quality synthetic oil changes, regular inspection of the supercharger system, and proactive servicing of cooling and sealing components. When properly maintained, the Mercedes-Benz M113E55 5.5L V8 Engine delivers outstanding performance, proven reliability, and iconic AMG character, making it an excellent investment for enthusiasts and premium engine replacements alike.
