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.
