Mercedes-Benz M178/M177/M176 engine

Mercedes-AMG developed the M176 ENGINE/M177/M178 V8 petrol engine series, which replaces the Mercedes-Benz M278 and Mercedes-Benz M157 engines and is based on the Mercedes-Benz M133 engine.

Two BorgWarner turbochargers are installed in the engine in a “hot-V” configuration, sandwiched between the two cylinder heads. Five squirts of gasoline are delivered by Bosch’s innovative piezo-electric direct fuel injectors, which are used in the fuel injection system.

2015 saw the introduction of the M176 variant for the Mercedes-Benz G 500/G 550 and G 500 4×42. 2019 saw the M176 get an EQ Boost mild hybrid 48V electrical system, which added 16 kW (22 PS) and 250 Nm (184 lb-ft) of torque to its output. [4] It was installed in the GLE 580 4MATIC and GLS 580 4MATIC vehicles. With improved output for the petrol engine (370 kW (503 PS; 496 bhp)) and reduced output for the EQ Boost (15 kW (20 PS), the M176 engine with EQ Boost was modified in 2021 for the S 580 4MATIC.

M177 ENGINE

The M177 was the Mercedes-AMG C63’s first variant to be made available. This variant of the engine makes use of wet-sump lubrication as opposed to the M178. The turbos in the C63 and GLC63 applications are single-scrolled, but the E63 and S63 applications use twin-scrolled turbos and unique exhaust manifolds. Cylinder deactivation is another characteristic of the twin-scroll application.

Aston Martin has installed the M177 engines in the DB11 V8 and DB Volante (2017-), Vantage (2018-), and DBX as part of the collaboration with Mercedes-AMG since 2013. (2021–).

Late in 2019, the M177 engines’ 48V system, which was used in the M176, was installed for increased performance, better fuel efficiency, and lower pollution levels.
