What does 'several liters of fuel consumption' mean?

[DiIsla]

It refers to the average fuel consumption of a vehicle per 100 kilometers traveled, measured in liters per 100 kilometers (L/100km). Below is an introduction to two fuel consumption evaluation metrics: 1. Constant-speed fuel consumption: This is a fuel economy indicator when a vehicle travels at a constant speed on a good road surface. Since constant-speed driving is a fundamental operating condition for vehicles on highways, and this type of fuel consumption is easy to measure, it is widely adopted. 2. Road cycle fuel consumption: This is a fuel economy indicator measured when a vehicle follows specified speed and time protocols for repeated cyclic driving on roads, also known as multi-condition road cycle fuel consumption. The speed and time protocols specify various driving conditions for each cycle, including gear shift timings, braking and stopping times, as well as driving speeds, acceleration, and braking deceleration values. Therefore, the fuel economy measured this way is closer to the actual driving conditions of the vehicle.
