What is the average fuel consumption per 100 kilometers for a car?

Generally speaking, a 1.0L displacement car consumes about 5 liters of fuel per 100 kilometers; a 1.5-1.6L displacement car consumes about 7 liters; a 1.8L displacement car consumes about 10 liters; and a 2.0L displacement car consumes about 10-12 liters. SUVs with the same displacement tend to have higher fuel consumption than sedans, so these figures are only a reference range. Fuel consumption per 100 kilometers refers to the amount of fuel a vehicle consumes when driving a certain distance at a specific speed. The formula to calculate fuel consumption per 100 kilometers is: Fuel consumption per 100 kilometers = Volume of fuel consumed (liters) ÷ Distance traveled (kilometers) × 100. The fuel consumption of a car is directly influenced by five main factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption include: Driving habits: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light can increase fuel consumption. The car itself: Cars with larger displacements generally consume more fuel than those with smaller displacements because higher displacement usually means greater power output, requiring more gasoline for combustion. Heavier cars also consume more fuel because greater weight demands higher driving torque. Road conditions: Driving on unpaved roads, muddy roads, soft surfaces, or mountainous terrain increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases aerodynamic resistance, leading to higher fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily during cold starts, requiring more fuel for combustion, which increases consumption. Additionally, in cold weather, the engine's computer may control the engine to run at higher RPMs to warm up, further increasing fuel consumption.
I think the fuel consumption per 100 kilometers for average cars depends on specific conditions, but ordinary sedans generally range between 7 to 10 liters. For compact cars I've driven, like those fuel-efficient Japanese models, city driving usually stays around 8 liters, while highway driving can drop to 6 or 7 liters. Fuel consumption varies significantly—if you frequently encounter traffic jams or accelerate aggressively, it can spike to over 12 liters, wasting money on fuel and potentially harming engine longevity. I recommend regularly checking tire pressure (neither too low nor too high) and avoiding overloading the car with unnecessary items to save some fuel. By the way, hybrid vehicles nowadays have even lower consumption; a friend’s hybrid averages just 5 liters and drives smoothly too.
