What is the average fuel consumption of the Mercedes-Benz C-Class?
4 Answers
The average fuel consumption of the Mercedes-Benz C-Class is 6.0-7.2L/100km. Vehicle Fuel Consumption: Generally, the onboard computer provides an average fuel consumption value, which is displayed on the dashboard, but it often differs slightly from the actual fuel consumption. Specific vehicle fuel consumption can be calculated using a formula. Fuel Consumption Considerations: Plan your route before driving, check traffic conditions, and try to avoid roads prone to congestion. Maintain a steady speed while driving, as unstable driving speeds can increase fuel consumption by approximately 6% in suburban areas and 2% in urban areas. Avoid carrying unnecessary items in the car to reduce vehicle weight.
Last month, I accompanied a friend to pick up the new Mercedes-Benz C260L. With the air conditioning on during city commutes, the actual fuel consumption was around 9 liters per 100 kilometers, while on the highway, it could drop to just over 6 liters. The 1.5T engine with 48V mild hybrid is indeed fuel-efficient, but frequent start-stop in heavy traffic can push consumption up to 11 liters. I recommend noting the mileage when refueling to calculate it yourself, as the car's displayed fuel consumption is generally about 0.5 liters lower than actual. If you drive aggressively in sport mode, the instantaneous fuel consumption can spike to 20 liters, but with gentle daily driving, a full tank of 95-octane gas can easily cover 600 kilometers. As an owner of the older C200 model, I can't help but feel envious—our 2.0T engine burns about 1.5 liters more fuel under the same conditions.
Three-Year Experience with Mercedes-Benz C180: Fuel Consumption Depends on Driving Habits! My 2.0T low-power version shows 13L/100km in morning rush hour traffic, but drops to 7.9L/100km on suburban weekend drives. The key is to keep the auto start-stop function on - engine shutdown at red lights significantly saves fuel. Factory-recommended energy-saving tire pressure at 2.6 bar saves 0.8L compared to 2.3 bar, with rear-wheel drive being more sensitive to tire pressure changes than front-wheel drive. For monthly mileage of 2,000km, 95-octane fuel costs about 1,500 RMB - saving about 100 RMB compared to Audi A4L in the same class but more expensive than Lexus ES. Attention for those upgrading to larger rims: a friend reported 1.2L/100km increase after switching to 19-inch wheels.
Last year's fuel consumption data for the entire Mercedes-Benz lineup was tested: the C200 standard version averaged 8.5L/100km, the 7-seater business shuttle recorded 11L for airport transfers, and the AMG C43 reached 19L under aggressive driving. The biggest factor affecting fuel consumption is actually speed—maintaining a steady 80km/h is the most economical. In northern winters below zero, fuel consumption increases by 1L, and using 0W-20 oil saves more fuel than 5W-30. The new electric motor assistance at startup can save 15% fuel, though the battery pack occupying trunk space is a matter of personal preference. For used cars, carbon buildup is a concern—vehicles with uncleaned throttle bodies at 60,000km can consume 2L more fuel.
