How much fuel is needed for 100 kilometers?

It mainly depends on the fuel consumption of the sedan (because sedans with different displacements consume different amounts of fuel). A sedan with a 1.0L displacement requires about 35 yuan in fuel costs for 100 kilometers; a sedan with a 1.3L displacement requires about 46 yuan in fuel costs for 100 kilometers. A sedan with a 1.6L displacement requires about 66 yuan in fuel costs for 100 kilometers; a sedan with a 2.0L displacement requires about 75 yuan in fuel costs for 100 kilometers. Generally, cars should be economical family sedans, i.e., those with displacements of 1.0L, 1.3L, 1.6L, and 2.0L, with fuel consumption per 100 kilometers approximately 5L, 7L, 10L, and 12L, respectively. The fuel price in recent years has generally been around 6.5 yuan, so the fuel cost for a typical sedan to run 100 kilometers is between 5*6.5 and 12*6.5, roughly ranging from 35 to 75 yuan. Although fuel consumption is related to displacement, this relationship is not absolute. A larger cylinder volume (displacement) can accommodate more combustible mixture (air-fuel), so under otherwise identical conditions, an engine with a larger cylinder volume (displacement) will inevitably have better/higher power/fuel consumption. During daily driving, the engine speed generally ranges between 1000 and 3000 RPM, and the maximum speed of an ordinary family car is only around 6000 RPM. In contrast, racing cars maintain speeds twice the limit of family cars (tens of thousands of RPM) during races, naturally resulting in high fuel consumption. Off-road vehicle owners who enjoy dune bashing like to drive in the desert and must refuel frequently. This does not mean that large-displacement vehicles are necessarily fuel-intensive; rather, it has to do with each person's driving methods and geographical environment. Widening and enlarging tires increases the friction of the tires, which is equivalent to increasing the load on the car, directly increasing the car's fuel consumption. At the same time, some car owners modify their cars with rear wings and body kits. Adding a rear wing undoubtedly increases the car's air resistance. At low speeds, the rear wing does not function at all and only increases driving resistance, thereby increasing the overall load on the car, which inevitably leads to higher fuel consumption.
