Mercedes G-Class Fuel Economy Malaysia — G63 AMG / G500
G63 AMG real-world: 18–25 L/100km city, 13–16 L/100km highway. The 4.0T V8 and 2,560 kg kerb weight make this one of the highest fuel users on Malaysian roads. ECO mode helps marginally; smooth throttle is the biggest factor.

G-Class Fuel Economy — Managing a Thirsty V8
- G63 AMG: city 18–25 L/100km, highway 13–16 L/100km — among highest on Malaysia roads
- ECO mode helps marginally; smooth progressive throttle is the biggest factor
- Correct tyre pressure (recommended PSI) + correct engine oil viscosity (0W-40/5W-40) both help
Fuel Economy — Mercedes-Benz in Malaysia
Mercedes-Benz official fuel economy figures are tested under European cycle conditions — real-world KL city driving returns significantly worse. C200 official: ~6.5 L/100km; city real: 10–13 L/100km. GLC 200 official: ~7.5 L/100km; city real: 12–15 L/100km. G-Class 4.0L V8: city real 18–22 L/100km. All petrol models use RON 95 minimum (RON 97 is recommended for performance models like C43/GLC43). Eco mode reduces throttle response and A/C power — effective in slow city traffic. The 9G-Tronic hunts less in D mode with lighter throttle inputs.
