Factors Affecting Mercedes-Benz GLC Mileage

The ARAI fuel economy estimates for GLC models range from 12 km/l to 17 km/l. What accounts for this difference and variation in the real-world mileage of this SUV? Here are the key factors:

  • Vehicle Configuration: The engine, drivetrain, and body style significantly impact mileage. For example, the GLC Coupe sacrifices aerodynamic efficiency for style, resulting in lower mileage. Engine configuration also plays a key role. 

For example, the more powerful twin-turbo V6 engine uses more fuel than the turbocharged inline variant. Also, the all-wheel drive (AWD) system makes the vehicle heavier, resulting in lower fuel efficiency.

  • Driving Style: Aggressive acceleration, speeding, hard braking, and excessive idling can considerably lower the fuel efficiency of your GLC. Gentle driving can help you optimise its mileage. Using cruise control and avoiding frequent speed changes also help maximise highway fuel efficiency.

  • Operating Conditions: Frequent short trips, cold weather, using A/C or heat, and frequent stop-and-go traffic can all contribute to your GLC's reduced fuel economy. Extended highway drives are considered the best for maximising mileage. Using Eco start-stop mode in city driving can help you improve your GLC’s fuel efficiency.

  • Vehicle Load: Extra weight can reduce the mileage of your GLC. Avoid carrying unneeded loads. Notably, additional roof racks and storage pods create aerodynamic drag, which can lower your car's mileage. Even filling up with premium fuel when not required can add unnecessary weight to the engine.

  • Vehicle Maintenance: Issues like under-inflated tyres, old spark plugs, and dirty air filters can reduce your GLC's mileage. Maintenance factors like sticking brakes, old transmission fluid, and a faulty oxygen sensor can lower your vehicle's mileage. Regular maintenance can help you keep your GLC running efficiently.

Consider changing your GLC's engine oil and filter at 15k-20k kilometres.

What driving mode should I consider to improve the mileage of my GLC?

Use the Eco mode as far as possible. It can help you adjust the transmission shift points, throttle response, and climate control for maximum mileage. On the other hand, selecting the comfort or sports modes would prioritise performance over fuel efficiency.
