How to Understand Fuel Consumption per 100 Kilometers?

Fuel consumption per 100 kilometers is calculated by dividing the amount of fuel used by the distance traveled in kilometers, which gives the fuel consumption per kilometer, and then multiplying by 100. Here is a related introduction about fuel consumption per 100 kilometers: 1. Calculation formula: Fuel consumption per 100 kilometers (liters) = Fuel consumption (liters) ÷ Distance traveled (kilometers) × 100. 2. Related factors: Fuel consumption per 100 kilometers is closely related to factors such as the age and condition of the vehicle, engine displacement, curb weight, and load. Generally, the older the vehicle and the larger the engine displacement, the higher the fuel consumption per 100 kilometers. Driving with windows open for cooling in summer on highways may not necessarily save fuel, as the drag coefficient increases, leading to higher fuel consumption.

I recently bought a used car and was particularly curious about its fuel consumption. After starting the car, I found the control button with a page-turning symbol on the left side of the steering wheel. Switching through the dashboard display, I discovered there were actually three sets of fuel consumption data: real-time fuel consumption would spike to 15L in traffic jams and drop to 6L on the highway; the single-trip record showed 8.2L for my daily commute; while the long-term average stayed at 9.5L. I specifically tested it by filling up the tank, driving 420 km, and then refueling 40L—the actual consumption was 9.52L/100km, with less than 0.1L deviation from the displayed value. The car's computer is quite accurate. Now I've developed a habit of glancing at the instantaneous fuel consumption at every red light, forcing myself to break the bad habit of stomping on the accelerator.

Last week, teaching my mom how to check fuel consumption was quite a challenge. Her Corolla only has a small LCD screen on the dashboard. First, you need to press the ODO button to switch to TRIP A, then hold it for two seconds to reset the trip data. After driving her to the market for 8 kilometers, she was amazed when the dashboard showed 7.8L/100km. The key is to remember the difference between two types of data: the long-term fuel consumption with a fuel pump icon represents the vehicle's overall performance, while the one with trip mileage is for single-trip data. Veteran drivers recommend resetting trip data after each refueling, so you can compare fuel consumption differences under various road conditions after finishing a full tank.

Driving a new energy vehicle also requires attention to energy consumption! In my hybrid Han DM, I press the up and down buttons on the right side of the steering wheel to switch to the energy flow interface and check the ratio of fuel consumption to electricity consumption. In pure electric priority mode, the urban electricity consumption is 18 kWh per 100 kilometers, which translates to just 8 cents per kilometer. On long trips, switching to hybrid mode displays the comprehensive fuel consumption, and with the steering wheel heating on, fuel consumption increases by about 0.6L. The instantaneous power display with a blue progress bar on the dashboard is super practical—when I press the accelerator hard and see the power bar turn red, I ease off the pedal a bit, reducing energy consumption by 20% this way.
