How to calculate fuel consumption and how much it costs per kilometer
As oil prices fluctuate and vehicle costs rise, how to calculate fuel consumption and cost per kilometer has become a focus of concern for car owners. This article will combine the hot topics on the Internet in the past 10 days, structurally analyze the fuel consumption calculation method, and provide practical data reference.
1. Basic formula for calculating fuel consumption
Fuel cost per kilometer = (fuel consumption × fuel price) ÷ mileage
in:
-Fuel consumption: Vehicle fuel consumption per 100 kilometers (L/100km)
-oil price: Current fuel unit price (yuan/liter)
-Mileage: Usually calculated based on 100km.
2. Fuel consumption reference of popular models in 2023
| car model | Official fuel consumption (L/100km) | Actual fuel consumption (L/100km) |
|---|---|---|
| BYD Qin PLUS DM-i | 3.8 | 4.2 |
| Toyota Corolla 1.2T | 5.6 | 6.3 |
| Honda CR-V 1.5T | 6.7 | 7.5 |
| Tesla Model 3 | 0 | 15kWh/100km |
3. Step-by-step calculation example (take 92# gasoline 8.5 yuan/liter as an example)
| Calculation steps | formula | Sample data | result |
|---|---|---|---|
| 1. Record the amount of refueling | After filling the tank, drive 300km and then fill it up again. | Fill up to 18 liters | - |
| 2. Calculate fuel consumption per 100 kilometers | Refueling amount ÷ mileage × 100 | 18÷300×100 | 6L/100km |
| 3. Calculate cost per kilometer | Fuel consumption×fuel price÷100 | 6×8.5÷100 | 0.51 yuan/km |
4. Five key factors affecting fuel consumption
1.driving habits: Rapid acceleration/braking increases fuel consumption by 20%
2.road conditions: Fuel consumption on congested roads increases by 30-50%
3.Vehicle load: Fuel consumption increases by 5-7% for every 100kg added
4.Air conditioning use: Fuel consumption increases by 10-15% under cooling conditions
5.tire pressure: Insufficient tire pressure increases fuel consumption by 2-4%
5. Top 3 fuel-saving tips (recent hot discussions)
| Skill | Implementation method | expected effect |
|---|---|---|
| Predictive driving | Keep distance between cars and reduce braking | Fuel saving 8-12% |
| Regular maintenance | Replace the third filter/spark plug on time | Fuel saving 3-5% |
| High speed window closing | Speed >80km/h Close the windows | Reduce wind resistance by 7% |
6. New energy vehicle energy consumption conversion
Electric vehicles can be driven by:
Cost per kilometer = (electricity consumption × electricity price) ÷ driving mileage
| car model | Power consumption per 100 kilometers | Household electricity cost (0.6 yuan/kWh) |
|---|---|---|
| Tesla Model Y | 14kWh | 0.084 yuan/km |
| BYD Han EV | 13.5kWh | 0.081 yuan/km |
7. Recommended fuel consumption calculation tools
1.Bear Fuel Consumption APP: Automatically record refueling data and generate reports
2.Amap fuel consumption statistics: Combined with intelligent analysis of navigation data
3.Excel template: Manual input to generate trend charts
It can be seen from the above structured data analysis that accurate calculation of fuel consumption needs to be combined with the actual use of the vehicle. It is recommended that car owners collect data once a month and establish personalized fuel consumption files, which is of great significance to controlling vehicle costs and environmentally friendly driving.
