Frequently Asked Questions
What is the M177 engine?
The M177 is Mercedes-AMG's hand-built 4.0L twin-turbo V8 with a hot-vee layout — turbos mounted inside the cylinder valley for faster spool and shorter intake paths. It uses wet-sump oiling and a cross-plane crankshaft.
M177 vs M178 — what is the difference?
Both are 4.0L twin-turbo V8s with cross-plane crankshafts. The M177 uses wet-sump oiling and is found in sedans and SUVs. The M178 uses dry-sump oiling and is exclusive to the AMG GT sports car. The GT Black Series adds a flat-plane crankshaft.
What horsepower can the M177 make?
With YPG forged internals and upgraded turbos, the M177 is rated to 1,500HP+ in race-application builds.
