The M176/M177/M178 is a gasoline V8 engine line-up designed by Mercedes-AMG. They are replacing the outgoing Mercedes-Benz M278 engine and Mercedes-Benz M156 engine line-up.
The V8 engine is the further development of the Mercedes-AMG M133 engine, two blocks sharing a single crankshaft.[1] However, the V8s are twin-turbocharged, with the BorgWarner turbochargers positioned between the two cylinder heads in a "hot-V" configuration. The injectors are Bosch's new piezo-electric direct fuel injectors, and they deliver five squirts of fuel per combustion cycle.[2]
Within the family, the M178 and M177 variations are used in Mercedes-AMG vehicles and assembled in the AMG base at Affalterbach, while the M176 is used in mainstream Mercedes-Benz models and assembled in Mercedes's Untertürkheim plant outside Stuttgart[3], starting with the 2015 G500 and G500 4X42.[4]

M177
The M177 was the first variation[5] released in the Mercedes-AMG C63. In contrast to the M178, this version of the engine uses wet-sump lubrication. In the C63 and GLC63 applications, the turbos are single-scrolled, whereas in E63 and S63 are twin-scrolled and different exhaust manifold. The twin-scroll application also features cylinder deactivation.[6] This engine is also used in the Aston Martin DB11 and the Aston Martin V8 Vantage (2019), as part of the agreement between Aston Martin and Daimler AG that began in 2013.[7][8][9][10]
