What does 'how many liters per 100 kilometers' mean?

[Tammy]

Fuel consumption in liters per 100 kilometers refers to how many liters of fuel are consumed per 100 kilometers. Below are detailed explanations of two types of fuel consumption: 1. Constant-speed fuel consumption: This is the fuel consumption per 100 kilometers obtained from standardized tests for certain types of vehicles driving at a constant speed, as specified by national standards. 2. Comprehensive cycle fuel consumption: 'Cycle fuel consumption' includes the 'theoretical fuel consumption' in vehicles, as 'theoretical fuel consumption' refers to the actual fuel consumption measured when a vehicle is driving at a constant speed under specific conditions (such as on a flat asphalt road, with the engine speed at 3000r/min, in the highest gear, with wind speeds of 3-4 levels, etc.).

This is a question I often encounter when helping my neighbor Uncle Wang check his car. 'How many liters per 100 kilometers' means asking how many liters of fuel this car consumes to drive 100 kilometers. For example, if the fuel consumption is 8 liters, it means your car consumes 8 liters of gasoline to travel 100 kilometers. The smaller this number, the more fuel-efficient the car is. For instance, my old sedan consumes about 10 liters, and the monthly fuel costs are quite painful. Actually, fuel consumption is closely related to driving habits. My son always steps on the gas pedal aggressively, and the same car ends up consuming 30% more fuel than mine. I suggest new drivers pay more attention to tire pressure and air conditioning usage, and gently pressing the accelerator can save a lot on fuel costs.

I remember when I bought my first car, I didn't understand what fuel consumption meant either. It's actually quite simple: for example, 6.5L/100km means the car consumes 6.5 liters of fuel per 100 kilometers. Now my SUV shows an average of 9.2 liters, and it can rise to around 10 liters in winter when using the heater. The key factor affecting fuel consumption is road conditions - being stuck in downtown traffic every day will definitely increase fuel usage. I recommend new car buyers check real fuel consumption reports from owner forums, which are much more reliable than the manufacturer's claims. Using cruise control on highways does save fuel, and I've personally tested this to be true.
