What is the fuel tank capacity of the Elantra?

Modern Elantra's fuel tank capacity is 47 liters, which is the officially announced data. The fuel grade for the Modern Elantra is 92, with a fuel consumption of 5.2-5.4L per 100 kilometers. A full tank can cover a distance of 870-903km. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank at all times. Generally, the fuel level is observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge on the dashboard usually has 5 to 6 segments. When the fuel gauge shows only 2 segments left, it is time to refuel to avoid running out of fuel midway. During the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity calibrated by the car manufacturer is from the bottom of the tank to the safety limit, and there is still some space from the safety limit to the tank opening. This space is reserved to ensure that the fuel inside the tank can expand when the temperature rises without overflowing the safety space of the tank. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.
I remember driving an Elantra before, with a fuel tank capacity of about 50 liters. A full tank could get me around 600 kilometers, which was more than enough for city commuting. I usually refuel when the gauge hits half to avoid running out of gas midway. When fuel prices rise, it doesn’t hurt as much because the tank size is just right, paired with an average fuel consumption of 6 liters per 100 kilometers—quite economical. Even for long trips, a full tank covers the entire journey without worry. A friend who owns an older car reminded me to regularly check the fuel tank seals to prevent leaks. Overall, the design is beginner-friendly, practical without being flashy.
As someone who enjoys tinkering with cars, I've measured the Elantra's fuel tank several times, and it's generally around 53 liters, with the latest model being more precise. The tank is mostly made of corrosion-resistant plastic and is positioned at the rear of the chassis to lower the center of gravity and enhance driving stability. In terms of driving experience, the fuel level changes evenly, and the fuel gauge responds smoothly without lag. I've also compared different model years, and the difference is minimal—for example, the 2018 model also holds over 50 liters. The tank is well-matched with the engine for efficiency and fuel economy, with the fuel level dropping almost uniformly on highways. I usually pay attention to the remaining range indicator when refueling to avoid misjudgment. The tank design incorporates safety measures, including an explosion-proof valve, to minimize risks in case of accidents.
