Generally, the displacement of an ordinary family sedan ranges between 1.5L and 2.0T, with a fuel consumption of 7L/100km to 10L/100km. Fuel Consumption: Automobile fuel consumption refers to the fuel consumption per 100 kilometers. Different vehicles have different displacements, resulting in varying fuel consumption per 100 kilometers. Additionally, fuel consumption is influenced by factors such as individual driving habits, road conditions, vehicle load, tire pressure, and weather. Calculation Method: Generally, the onboard computer provides an average fuel consumption value, which is displayed on the dashboard, but it often differs slightly from the actual fuel consumption. The specific fuel consumption of a car can be calculated using the following formula. Calculation method: Fuel consumption per 100 kilometers = Fuel consumed ÷ Distance traveled × 100.

I've driven various small cars, like the compact Honda Fit or Toyota Corolla, and found that the average fuel consumption per 100 kilometers ranges between 5 to 10 liters, with around 7 liters being quite common. The exact figure depends on the model year—newer turbocharged engines might go as low as 5 liters, while older or higher-displacement models could exceed 9 liters. Driving habits play a big role; if you maintain a steady speed of 60-80 km/h on the highway, you can easily bring it down to 6 liters. But in congested urban traffic with constant stop-and-go, it’s normal for consumption to spike to 10 or even 12 liters. Vehicle condition is also crucial—low tire pressure can add 0.5 liters, and a dirty air filter increases fuel use. My advice: check the official fuel economy data when buying a car, and practice smooth acceleration with minimal hard braking in daily driving—it’ll save you a lot on fuel and extend engine life.

As a driver who commutes regularly by car, my small car's fuel consumption fluctuates around 7 liters per 100 kilometers. Why is there such a big variation? Engine technology is the main factor—for example, a 1.0L small-displacement car might consume 5.5 liters, while a 2.0L engine can reach 9 liters. Driving habits also play a role; if I tend to accelerate aggressively and brake suddenly, fuel consumption can easily jump to 10 liters. Road conditions have a significant impact too—on smooth highways, it can drop to 5.8 liters, but on rainy, snowy, or hilly roads, it may rise above 8 liters. I've also noticed that maintenance is crucial: regular oil changes to keep the engine lubricated and checking spark plugs every six months can improve fuel efficiency by about 0.5 liters. A fuel-saving tip is to develop a gentle driving habit, avoid excessive warm-up time to prevent unnecessary waste, and adjust the air conditioning temperature moderately instead of blasting cold air.

In the past, I drove many small cars with an average fuel consumption of around 8 liters per 100 kilometers. However, cars have improved rapidly in recent years, and now it's easier for new cars to achieve around 6 liters. For example, common compact models like the Volkswagen Polo or Ford Fiesta typically range between 5.5 to 7 liters. Climate and temperature play a role—using air conditioning in hot summers may slightly increase consumption by 0.3 liters, while cold winters with slower engine warm-up can lead to higher fuel usage. Effective fuel-saving methods include choosing lightweight body models and maintaining a steady speed, which can help keep consumption within a reasonable range.
