Key Engineering Innovations of the M177
AMG didn’t just build a powerful V8—they designed it with advanced technology and engineering solutions that make it unique.
1. “Hot V” Turbocharger Configuration
Unlike traditional V8s, AMG mounted the twin turbos inside the V of the engine, reducing turbo lag and improving throttle response.
✔ Benefits:
- Faster turbo spool-up for instant power
- More compact engine design
- Improved airflow and efficiency
2. Lightweight Construction for Better Performance
The M177 features an aluminum block and lightweight internals, reducing weight without compromising strength.
✔ Benefits:
- Better power-to-weight ratio
- Increased efficiency without sacrificing durability
3. Advanced Cooling System
To handle high performance demands, the M177 uses a sophisticated air-to-water intercooler system.
✔ Benefits:
- Maintains optimal temperatures during aggressive driving
- Prevents heat soak, ensuring consistent performance
4. Cylinder Deactivation for Efficiency
In some models, the M177 features cylinder deactivation, shutting off four cylinders under light loads to improve fuel economy.
✔ Benefits:
- Lower fuel consumption
- Reduced emissions without sacrificing power
