Fuel consumption of 6.7 costs about 0.4 yuan per kilometer, but this may vary depending on different types of fuel prices. Below is relevant information: 1. Driving habits: Driving habits can affect fuel consumption. Rapid acceleration and sudden braking in urban and highway driving may increase fuel consumption by 5%-30%. Additionally, idling is a major bad habit that increases fuel consumption. Prolonged idling increases vehicle fuel consumption because the vehicle consumes energy as long as it is running, and prolonged idling is also very harmful to the car engine. 2. External environment: Road conditions and weather can affect fuel consumption. When road conditions are poor, frequent stops and starts, and switching between throttle and brake, can easily increase fuel consumption. Generally, smooth roads are more fuel-efficient than bumpy roads, straight roads are more fuel-efficient than curved roads, and clear roads are more fuel-efficient than congested roads. In summer, hot weather and air conditioning use can consume some fuel. In winter, low temperatures prevent gasoline from reaching the optimal combustion temperature, leading to incomplete combustion and some fuel loss.

Having driven for thirty years, a fuel consumption of 6.7L/100km is quite common. Calculating the cost per kilometer in cents is actually straightforward. First, check the current fuel price—let's say the average is around 8 yuan per liter. Multiply 6.7 by 8 to get 53.6 yuan per 100 kilometers, then divide by 100 to get 0.536 yuan per kilometer. Since one yuan equals ten cents, that's roughly 5.36 cents per kilometer. In real-world driving, fuel prices fluctuate, so it's best to check local real-time prices via a mobile app before calculating. I personally track every refueling expense to manage my budget precisely. Maintaining fuel-efficient driving habits, like avoiding sudden acceleration, can lower consumption below 6L/100km, reducing the cost to under 5 cents per kilometer. This approach is most practical for daily commutes—driving 2,000 km monthly could save hundreds of yuan.

As a parent who frequently drives, I have to budget carefully for household expenses. For a car with a fuel consumption of 6.7L/100km, calculating the cost per kilometer in terms of 'mao' (a Chinese unit of currency), for example, if the fuel price is 7.5 yuan per liter, the fuel cost for 100 kilometers would be 50.25 yuan. Dividing by 100 gives a cost of 0.5025 yuan per kilometer, which converts to 5.025 mao. If I drive 1,500 kilometers in a month, the fuel cost would be over 750 yuan, which has a significant impact on the family budget. I would recommend refueling at reputable gas stations for more reliable fuel quality, and combining this with driving habits such as avoiding congested urban areas to reduce fuel consumption. These experiences help me plan better during fuel price fluctuations, such as avoiding peak hours for refueling to save costs. Remember, the actual fuel consumption of your car is more accurate than the display; I often use a notebook to record mileage and refueling amounts to verify this.

I care about driving costs and also consider environmental impact. A fuel consumption of 6.7L/100km means burning 6.7 liters of gasoline per 100 kilometers, resulting in certain carbon emissions. But the main focus is on expenses—when the oil price is 7.8 yuan, it costs about 0.5226 yuan per kilometer, or 5.226 mao. This spending level isn’t high, but optimizing driving habits like maintaining steady speed and using air conditioning less can reduce fuel consumption to around 6L, lowering the cost to below 0.5 yuan per kilometer. Meanwhile, I lean toward hybrid or fuel-efficient cars to cut long-term costs. For short trips in the city, I opt for electric shared cars, which save fuel and are eco-friendly in the long run.
