What is the M156 Engine?

The M156 is a 6.2-liter naturally aspirated V8 engine designed and built by Mercedes-AMG. It was the first in-house designed engine by AMG, rather than modifying existing Mercedes-Benz engines. The M156 was introduced in 2006 and was used in a range of AMG high-performance cars including:

Mercedes-Benz E63 AMG
C63 AMG
SL63 AMG
CLS63 AMG
S63 AMG
ML63 AMG
R63 AMG

This 6.2L V8 is renowned for its exceptional balance of high power output, mechanical durability, and intoxicating soundtrack. It produces 451 to 518 horsepower, depending on the model and configuration.

Why Buy the M156 Engine?

When you’re looking for a Mercedes AMG engine, the M156 is a good buy for a number of reasons:

1. Proven AMG Performance

The M156 was a breakout engine for AMG. It put the Mercedes-AMG lineup on an equal footing with BMW M and Audi RS on a global level. With its track-tested durability and street-level refinement, it is a dream engine for individuals who love high-performance vehicles.

2. High-Output and Naturally Aspirated

During the era of turbocharged engines, the naturally aspirated nature of the M156 gives you a raw, pure driving experience. You get instant throttle response, a linear power curve, and a throaty exhaust note that’s hard to replicate.

3. Perfect for Swaps and Rebuilds

Need to do an engine swap on a project car or restore a wrecked AMG model? Our M156 engines for sale are perfect for performance cars, engine swaps, or restoration.

4. Built with Racing DNA

Forged internals and a high-revving redline make this engine a racer’s dream. AMG even borrowed much of the M156’s characteristics from their motorsports programs.

Applications of the M156 Engine

This engine was used in numerous high-performance AMG models from the mid-2000s to early 2010s:
