Depending on the engine displacement of the vehicle, the fuel consumption per kilometer varies. Generally, for sedans with an engine displacement below 2.0L, the fuel consumption is approximately 0.05-0.07L per kilometer. Below is some relevant information about fuel consumption: 1. Fuel consumption per 100 kilometers: This refers to the amount of fuel consumed by a vehicle traveling 100 kilometers at a certain speed on the road. It is a theoretical indicator of the vehicle. The fuel consumption per 100 kilometers is a value measured by manufacturers using a dynamometer installed on the vehicle's chassis under objective conditions, converted into speed parameters, and then calculated as the theoretical experimental fuel consumption data for the vehicle model when traveling at specified speeds. 2. Road condition fuel consumption: This is a fuel consumption indicator calculated based on values determined through repeated tests of a vehicle traveling on specified roads at prescribed speeds and times, also known as multi-condition road cycle fuel consumption. The standard specifies that each cycle includes various driving conditions and records driving conditions based on various indicators such as specified shift times, parking durations, driving speeds, acceleration, braking, and deceleration in each cycle. The values measured using this method are closer to actual values.

I've been driving a small car for over ten years. My car usually consumes 6 to 7 liters of fuel per 100 kilometers, which is approximately 0.06 to 0.07 liters per kilometer. In city traffic congestion, the fuel consumption can go up to 10 liters, while on the highway, it drops to around 5 liters, largely depending on the car's age and maintenance. My experience is that new car engines are more efficient, and changing oil regularly and maintaining proper tire pressure can save a lot. Climate also affects fuel consumption: warming up the car in winter consumes more fuel, while not using air conditioning in summer can save about half a liter. Driving habits are crucial—gently pressing the accelerator when starting, avoiding sudden braking and acceleration, and maintaining a steady speed are best. Generally speaking, small cars consume less, while SUVs consume more. Choosing the right car can save you a lot of hassle.

I'm the type who keeps a close eye on expenses, and saving a bit on fuel adds up to big savings. A compact car typically uses 6 liters per 100 kilometers, about 0.06 liters per kilometer, costing just a few cents at current fuel prices; an SUV might consume 10 liters, doubling the fuel cost. I always choose smooth roads and travel during less congested times. Using air conditioning increases fuel consumption, so in summer, I opt for ventilation instead. Maintaining a steady speed of 50-80 km/h is most economical, while sudden acceleration spikes fuel usage. Regular maintenance is the secret: cleaning the fuel system and replacing spark plugs keep the engine running smoothly and save fuel. Over the years, developing good habits can reduce fuel consumption by 10%, keeping both my wallet and car healthy.

From an environmental perspective, fuel consumption is a key concern. Lower fuel consumption per kilometer means fewer emissions. A small car consuming around 8 liters per 100 km is considered mid-range, while hybrid or electric vehicles can reduce this to 2-3 liters. Driving habits like easing off the accelerator and coasting more can cumulatively reduce pollutant emissions. Maintaining a steady speed within 70 km/h ensures reasonable fuel efficiency, as driving too fast on highways increases exhaust emissions. Choosing vehicles with efficient engines supports sustainable development.
