How much fuel does a car consume per kilometer?
2 Answers
Generally, a car consumes about 0.07L of fuel per kilometer. Below is a related introduction about the corresponding relationship of fuel consumption per 100 kilometers: Fuel consumption and engine displacement: Although fuel consumption is related to engine displacement, this relationship is not absolute. A larger cylinder volume (displacement) can accommodate more combustible mixture (air-fuel mixture), so under all other conditions being equal, an engine with a larger cylinder volume (displacement) will inevitably have better/higher power/fuel consumption. Fuel consumption and engine speed: During daily driving, the engine speed range is generally between 1000-3000 RPM. The maximum speed of an ordinary family car is only around 6000 RPM, while racing cars maintain operation at twice the maximum speed of family cars (over 10,000 RPM) during races, naturally resulting in much higher fuel consumption.
As an ordinary person who drives frequently, I believe the amount of fuel consumed per kilometer mainly depends on the type of vehicle and road conditions. When my sedan is stuck in city traffic, it consumes about 0.12 liters of gasoline per kilometer due to frequent stops and starts, long idling times, and higher fuel consumption. On the highway at a steady speed, it drops to a more economical 0.08 liters. Many factors influence this, such as using the air conditioning, which adds around 0.03 liters, or underinflated tires, which waste fuel. During my daily commute, I maintain smooth acceleration and avoid sudden braking, keeping consumption around 0.1 liters. However, fuel efficiency varies from person to person, so I recommend tracking your mileage and fuel refills monthly to calculate your own consumption rather than relying solely on manufacturers' advertised figures. Safe driving is more important—don’t sacrifice road awareness just to save fuel.
