What does 'how many liters per 100 kilometers' mean for a car?

[MaddoxMarie]

It refers to how many liters of fuel are consumed per 100 kilometers. This is an important parameter used to measure a vehicle's fuel economy, and the value may vary under different conditions. People often say that the gasoline consumption per kilometer driven by a car is also a standard for measuring general vehicle fuel consumption. Generally speaking, a car's fuel consumption refers to its fuel consumption per 100 kilometers, i.e., how many liters of fuel are needed to drive 100 kilometers. This is the theoretical indicator of the vehicle. The fuel consumption per 100 kilometers refers to the value measured by the manufacturer using a dynamometer installed on the vehicle chassis, converted into speed parameters, and then driving at a specified speed to calculate the theoretical experimental data of the vehicle's fuel consumption per 100 kilometers.
