What is the fuel consumption of a car?
2 Answers
Different cars, different engine displacements, and different driving habits result in varying fuel consumption. Generally, a family sedan with a displacement of around 1.6 liters will consume about 6-8 liters per 100 kilometers. Check the tires: Make sure the tire pressure meets the standard. If the tires are underinflated, fuel consumption will increase. Also, check the degree of tire wear. Severely worn tires can frequently cause slippage, leading to higher fuel consumption. Clutch: A slipping clutch can cause the engine RPM to rise without a corresponding increase in speed. If you notice the engine RPM increasing rapidly during hard acceleration but the vehicle speed does not increase accordingly, it may indicate a slipping clutch. Additionally, if the spark plugs are worn out, fuel consumption may increase. Damaged spark plugs reduce ignition efficiency, slowing down acceleration and significantly increasing gasoline consumption.
I've been driving to work for many years and found that car fuel consumption is actually not fixed, mainly determined by the vehicle model and driving habits. For example, my own compact sedan can consume up to 10 liters per 100 kilometers in city traffic jams, but drops to around 6 liters on the highway. Rapid acceleration and frequent braking are major fuel killers, while smooth driving can save at least 15% fuel. Running the air conditioner at full blast also consumes more fuel; using recirculation mode in summer helps a bit. If tire pressure is too low, it increases friction and raises fuel consumption by 3-5%, so I make it a habit to check monthly. Regular maintenance like changing engine oil and air filters keeps the engine running smoother and burns less fuel. Generally speaking, small cars average 6-8 liters, mid-size cars 8-10 liters, and large SUVs may exceed 12 liters—it really depends on how you drive.
