What is the capacity of a car's fuel tank in liters?
2 Answers
The capacity of a car's fuel tank varies depending on the vehicle model: 1. Mini and small cars range between 35 to 55 liters; 2. Compact and mid-size cars range between 55 to 70 liters; 3. Large full-size SUVs are around 100 liters. The fuel tank capacity refers to the maximum safe volume of the tank as announced by the manufacturer, with 'L' indicating the size of the tank capacity, which also determines the driving range. For two cars with identical engines, the larger the fuel tank, the farther the car can travel. Fuel tanks can be divided into two types: open tanks and closed tanks, whose function is to store the working fluid required by the hydraulic system, as well as to dissipate heat, precipitate impurities, and separate air bubbles from the liquid.
The size of a car's fuel tank isn't fixed. Having driven several models, I've noticed that compact cars usually have 40 to 60 liters—my Nissan Sylphy has a 45-liter tank, requiring frequent refueling. Mid-size SUVs like the Toyota RAV4 hold around 60 liters, offering better range. However, large off-road vehicles such as the Land Rover Range Rover can exceed 100 liters, though their heavier weight leads to higher fuel consumption. When designing fuel tanks, manufacturers must balance weight and safety, adhering to national standards to prevent accidents. Smaller tanks are more environmentally friendly, while larger ones suit long-distance travel. Before purchasing, check the owner's manual or specifications to match your needs and avoid wasting money on fuel.
