How many kilometers can a car run on a full tank of gas?

Generally, a full tank of gas can allow a car to run 400-600 kilometers. If driving in suburban areas or on highways, it can usually run over 600-700 kilometers. The details are as follows: 1. The fuel tank capacity of a car is generally large enough to allow a range of 400~600 kilometers. Lighter cars with smaller displacements have correspondingly smaller fuel tank capacities. 2. Heavier cars with larger displacements naturally have larger fuel tank capacities. 3. The maximum range on a full tank of gas is mostly between 400~600 kilometers. Additional information: Fuel tank capacity measurement unit: International standards use liters (L) as the unit for measuring car fuel tank capacity. Different countries also have corresponding standards for fuel tank capacity. In China, the fuel tank capacity is regulated to be 95% of the rated value, but in reality, the actual capacity is usually larger than the nominal capacity.
After driving for over a decade, I've found there's no standard answer to this issue. Fuel tank capacity and fuel consumption together determine the range. For example, my family's SUV has a 55-liter tank and consumes 10 liters per 100 km in the city, giving a range of about 550 km. However, my cousin's sedan has a smaller 40-liter tank but lower fuel consumption at 6 liters per 100 km, allowing it to run 650 km. The most practical approach is to check the range display on the dashboard, which recalculates every time you fill up the tank. Factors like tire pressure, whether the AC is on, and driving conditions (highway or traffic congestion) all affect fuel consumption. When I go on long trips, I usually estimate by dividing the tank capacity by the actual fuel consumption, which gives me a better idea of the range.
When I first started learning to drive, I was really confused about this issue. Later, I realized that the range mainly depends on two key factors. First is the fuel tank capacity – regular cars usually have 40-60 liters, while SUVs might have 70 liters or more. Second is the current fuel consumption, which is displayed on the dashboard or mobile app. If you frequently brake hard or accelerate aggressively, the fuel consumption will be much higher. I've recorded several full-tank records: commuting in the city gives about 450 km, while highway driving can reach 700 km. My advice for beginners is not to rely solely on official data – testing it yourself a few times is the most accurate.
As a car enthusiast, I've researched this issue, and fuel tank and engine technology are the key factors. Older engines generally have higher fuel consumption, resulting in shorter range with the same tank capacity. Nowadays, turbocharging combined with direct fuel injection technology makes engines much more fuel-efficient. For example, my friend's new car with a 1.5T engine has a 60-liter fuel tank and consumes only 5.8L per 100km, theoretically achieving over 1,000 km of range. Of course, actual road conditions will reduce this, but technological advancements are indeed increasing range year by year.
