What is the fuel consumption on highways and ordinary roads?
4 Answers
Highway fuel consumption varies depending on factors such as engine displacement and driving speed. Generally, for most sedan models, driving at 100 km/h on highways consumes about 6-10 liters per 100 kilometers. On urban roads, fuel consumption tends to be higher, averaging around 7-14L per 100 kilometers on ordinary roads, which is also influenced by individual driving habits. Below are some methods to reduce fuel consumption: 1. Maintain proper tire pressure: The normal tire pressure range is usually between 2.3-2.5 bar. If the tire pressure is lower than this range, the increased contact area between the tire and the road surface results in greater friction resistance, leading to higher fuel consumption. 2. Regular vehicle maintenance: Timely maintenance ensures proper lubrication of the powertrain system by the engine oil and helps detect potential vehicle issues early, reducing carbon buildup, which in turn aids in lowering fuel consumption.
I think there's quite a difference in fuel consumption between highways and regular roads, mainly depending on driving habits and vehicle type. Generally, fuel consumption is lower on highways because the speed stays stable around 70-80 km/h, making the engine run more efficiently and saving a lot of fuel. On regular roads, frequent stops and starts at traffic lights cause fuel consumption to climb, wasting money on gas. For example, my old sedan uses about 7-8 liters per 100 km on highways, but over 10 liters on regular roads, and can go up to 12 liters in traffic jams. There are many influencing factors: low tire pressure increases fuel consumption, and using the AC adds extra load. If you want to save money, choose highways for long trips, maintain your car well, and check spark plugs and air filters—it can help you save a lot of cash.
From an economic perspective, highways are significantly more fuel-efficient than regular roads. I usually drive to and from work and have noticed that fuel consumption is lower on highway sections, averaging about 7 to 9 liters per 100 kilometers. On regular roads, especially in urban areas, fuel consumption rises to 10 to 14 liters, mainly due to frequent traffic lights and lane-cutting, which waste fuel and money. For example, over a month of commuting, prioritizing highways can save you dozens of yuan in fuel costs. But don’t just look at the surface—vehicle type plays a big role: compact cars are more fuel-efficient on highways, while SUVs consume more on regular roads. Seasonal changes also matter, as using the heater in winter increases fuel consumption. My advice is to maintain a steady speed on highways and use cruise control more often. On regular roads, try to minimize sudden braking and regularly check your engine’s condition—this can help optimize your expenses.
When I first started learning to drive, I was puzzled why highway fuel consumption is lower. It's actually quite simple: driving at a constant speed on the highway doesn't strain the car much, so it uses less fuel; on regular roads, frequent acceleration and waiting at traffic lights increase fuel consumption. I drive a small-displacement car, typically consuming about 8 liters per 100 kilometers on the highway, while on regular roads it's around 11 liters. Traffic conditions are key: the difference is small when traffic is smooth, but fuel consumption on regular roads can double during congestion. As a beginner, remember to check tire pressure and engine oil to avoid wasting fuel; don't speed on the highway—it saves fuel and is safer. Simple and easy-to-understand experience!
