I've always been a car enthusiast, especially fascinated by Mercedes-AMG engines. The Mercedes G63 is powered by a 4.0-liter V8 biturbo engine, model M177, which is quite common in the AMG family. It delivers an impressive 585 horsepower and 850 Nm of torque, with explosive acceleration—0 to 100 km/h in just about 4.5 seconds, making it feel like a small rocket. Technically, it features a twin-scroll turbocharging system for quick response and can deactivate cylinders to save fuel and reduce emissions when needed. I drove it for a few days, and the engine sound is deep and powerful. Paired with the G63's off-road chassis, it handles both highways and rough terrain effortlessly. However, its fuel consumption is on the higher side, so daily commuting requires a slightly bigger budget. Also, AMG's bespoke maintenance pays extra attention to handcrafted details.

As a long-time driver of the Mercedes-Benz G63, I must say the engine experience is fantastic. It's a 4.0-liter V8 biturbo design. The first impression when driving is the endless power supply, with an immediate strong sense of acceleration when stepping on the gas, especially stable like an ox when overtaking on highways. The exhaust note is deep and powerful at low RPMs, perfectly matching AMG's sporty style. Although it's on the heavy side, the steering is precise, making it suitable for both daily commutes and weekend getaways. I particularly appreciate its reliability; the engine uses innovative materials to reduce weight, unlike the older models that were prone to overheating. However, the maintenance intervals are shorter, requiring regular oil changes, and the city fuel consumption is close to 15 liters, though it can be slightly reduced in eco mode. Compared to the G550, the G63 has more aggressive power, especially exciting on mountain roads, but its weight causes a slight delay in initial acceleration.

From the perspective of automotive history, the engine of the Mercedes-Benz G63 has undergone significant changes. It originally featured a large-displacement naturally aspirated V8, but in 2015, it was replaced with the current 4.0-liter V8 biturbo system, codenamed M177. This engine is exclusive to AMG, delivering 585 horsepower and 850 Nm of torque, making it considerably more efficient and faster in acceleration compared to its predecessor. Throughout the evolution of the G-Class, this engine has emphasized reliability, addressing some of the old issues, while AMG's signature hand-built assembly ensures each engine remains unique. This powerplant is also used in the E63 and C63 AMG models, showcasing its broad adaptability as the core powertrain for Mercedes-Benz's high-performance vehicles.
