Below is everything you’d ever want to know about these phenomenal engines—and why buying your engine from us is a guarantee of reliability, horsepower, and value.

1. Overview of the M176, M177, and M178 Engines

Mercedes-AMG launched its new 4.0-liter twin-turbocharged V8 engine family around the mid-2010s to take the place of the naturally aspirated M156/M159 and the twin-turbo M157. All three of these new engines—M176, M177, and M178—are based on the same general design. They are detuned for different applications, however.

This is a concise overview:

M176 – Used in luxury Mercedes-Benz vehicles like the S-Class and GLS, tuned down for comfort and smoothness.

M177 – Used in high-performance AMG coupes, sedans, and SUVs, i.e., the C63, E63, G63, etc.

M178 – Used in track versions of the AMG GT line with dry sump lubrication and motorsport modifications.

Each one of these motors is a work of art in itself, and now you can buy M176, M177, and M178 motors from us directly, ready to install or swap.

2. Why Are These Engines So Special?

All M176/M177/M178 engines share a lightweight compact 4.0L aluminum V8 twin turbocharged and direct injected in the “hot V” — between the cylinder banks. This gives:

Instant throttle response

Less turbo lag

Compact engine packaging

Improved thermal efficiency

Not like most other modern engines that sacrifice sound and character, these AMG engines are raw, muscular-sounding, and possess prodigious torque across the entire rev range.

And since all three variants share core architecture, we’re able to offer a wide selection of compatible engines for swaps, rebuilds, and direct replacements.

4. Specs and Differences Between the Engines

 

Engine	Displacement / Layout	HP Range	Torque Range	Oiling System	Application
M176	4.0L V8 Biturbo (Hot V)	463–503 HP	516–553 lb-ft	Wet Sump	Luxury sedans & SUVs
M177	4.0L V8 Biturbo (Hot V)	469–603 HP	479–627 lb-ft	Wet Sump	AMG sedans & SUVs
M178	4.0L V8 Biturbo (Hot V)	469–730 HP	465–590 lb-ft	Dry Sump	Track / Performance vehicles

The most important mechanical difference is that the M178 features dry-sump lubrication, forged internals, and hardened hardware. It’s perfect for hard driving or racing.

All three motors can be had remanufactured or used, depending on your budget and requirements.

5. Common Issues & Why Replacement

While these motors are robust, especially compared to worn-out M157s, they are by no means perfect. These are the most common reasons people bring M176, M177, or M178 engines to us for sale:

Turbocharger Failure
Pre-mature failure of the turbo due to heat soak or starvation of oil.

Oil Leaks & Oil Cooler Failures
A typical condition in the high-mileage motors, especially where OEM gaskets deteriorate.

Timing Chain Rattle or Stretch
Chain tensioner or stretch failure will cost a fortune.

Misfires or Low Compression
Oftentimes due to carbon buildup, piston ring failure, or valve failure.

Catastrophic Engine Failure
Engine overheating or oil starvation will crack blocks or pistons.

In all such cases, we prefer to replace with a brand new, fully tested, and inspected M176, M177, or M178 engine instead of rebuilding.

6. Used vs. Remanufactured: What We Offer

We carry a range of engines to meet different needs and budgets.

Used Engines:

Leak, compression, and dyno-tested

Best choice for OEM replacement at a lower cost
