The Mercedes — Benz M 176.980 is a 3,982 cc, twin — turbocharged V8 petrol engine produced between 2014 and 2019. It powered high — performance AMG models including the C 63 AMG, E 63 AMG, and GT, delivering 350 kW (476 PS) and 650 Nm of torque. Featuring a 90° V8 configuration, DOHC 32 — valve layout, and direct fuel injection, it introduced a hot — V turbo layout for improved throttle response and compact packaging.

All production years 2014–2019 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/9012).
The Mercedes-Benz M 176.980 is a 3,982 cc 90° V8 twin-turbocharged petrol engine developed for high-performance AMG applications (2014–2019). It combines dual overhead camshafts and 32-valve architecture with direct fuel injection and a hot-V turbo layout to deliver rapid throttle response and motorsport-inspired performance. Designed to meet Euro 6 emissions standards, it represents the first generation of Mercedes-AMG's downsized, turbocharged V8 engines.

The Mercedes-Benz M 176.980 was used across Mercedes-Benz's W205/W213/C190 platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-reinforced engine mounts in the W205 and revised intake manifolds in the W213-and from 2018 the facelifted W205 adopted the M177 variant with updated cooling, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The M 176.980's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in track or high-load use. Internal Mercedes-Benz service data from 2016 reported a notable share of pre-2017 engines requiring HPFP replacement before 120,000 km, while UK DVSA records link a significant portion of emissions-related MOT failures to catalytic converter degradation in city-driven vehicles. High-temperature cycles and extended idling increase turbo and fuel system stress, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M 176.980 offers exceptional performance and robust construction, but early models (2014–2016) are prone to high-pressure fuel pump wear. Later revisions (post-2017) improved durability with updated materials and cooling. When maintained properly—especially with timely oil changes using 5W-40 MB 229.5 oil—these engines can exceed 200,000 km. Regular inspection of intake manifolds and ignition components is advised.
The most documented issues are HPFP wear (causing hard starting), intake manifold vacuum leaks, ignition coil failures, and coolant leaks from thermostat housing. These are confirmed in Mercedes-Benz service bulletins. Carbon buildup on intake valves is common due to direct injection. Emissions components like catalytic converters are prone to degradation in short-trip usage.
This 4.0L twin-turbo V8 was used exclusively in AMG performance models: the W205 C 63 AMG (2014–2018), W213 E 63 AMG (2016–2019), and C190 GT (2015–2018). It was not used in any smaller platforms or licensed to other manufacturers. All applications featured rear-wheel drive with 7G-TRONIC PLUS or AMG SPEEDSHIFT MCT transmission.
Yes, the M 176.980 is highly tunable. ECU remapping can yield +60–100 kW by optimizing boost, fuel, and ignition maps. Aftermarket upgrades like larger turbos, intercoolers, and exhausts can push output beyond 550 kW. However, stock internals are stressed at high power levels. Reliability decreases significantly above 500 kW without forged internals and enhanced cooling.
Fuel consumption is high for a performance V8. In a C 63 AMG, typical usage is ~12.0 L/100km (city) and ~8.0 L/100km (highway), or approximately 23.5 mpg UK combined. Real-world figures depend heavily on driving style, but expect 18–22 mpg (UK) under mixed conditions. The engine requires premium unleaded (RON 98) for optimal performance and knock prevention.
Yes. The M 176 series is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in severe internal damage. The front-mounted double-row chain is robust but tensioner wear can occur. Any unusual front-end noise should be investigated immediately to prevent catastrophic failure.
Mercedes-Benz specifies 5W-40 oil meeting MB 229.5 standard. This high-performance synthetic ensures proper turbo bearing and HPFP protection under load. Oil must be changed every 15,000 km or annually to prevent sludge and component wear. Using incorrect viscosity or non-compliant oil can accelerate HPFP failure and void historical warranty claims.
