Frequently Asked Questions
What is the M178 engine?
The M178 is the dry-sump variant of AMG's 4.0L twin-turbo V8, exclusive to the AMG GT sports car family. It shares the hot-vee twin-turbo layout with the M177 but uses dry-sump oiling for sustained high-G cornering. The GT Black Series variant adds a flat-plane crankshaft.
M178 vs M177 — what is the difference?
The M178 uses dry-sump oiling and is exclusive to the AMG GT. The M177 uses wet-sump oiling and is found in sedans and SUVs. Both are 4.0L twin-turbo V8s with cross-plane crankshafts — the flat-plane crank is specific to the GT Black Series.
Can the M178 make 1,500HP?
Yes. With YPG forged internals and appropriate turbo upgrades, the M178 is rated to 1,500HP+ in race-application builds.
