Vehicle fuel tank capacity varies by 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 safe volume announced by the manufacturer, where liters indicate the size of the tank and determine the driving range. For two cars with identical engines, the larger the fuel tank, the farther the car can travel. Fuel tanks can be categorized into: 1. Open-type fuel tanks; 2. Closed-type fuel tanks, which function to store the working fluid required by the hydraulic system, while also dissipating heat, settling impurities, and separating air bubbles from the liquid.

I've always believed that fuel tank capacity depends on the specific model. For example, my regular family sedan is officially rated at 55 liters, but I've actually managed to fill it with up to 58 liters. I recommend checking your owner's manual or the sticker on the driver's side door frame for the exact figure. Tank size directly affects range - before long highway trips, I calculate: with a 55-liter tank and 8L/100km consumption, a full tank gives nearly 700km range. There's significant variation between models - compact cars like the Fit have just 40L tanks, while SUVs like the Highlander can hold 72L. Remember never to exceed safe capacity when refueling - once I overfilled in a hurry and the gasoline fumes were not only unbearable but also extremely dangerous.

Fuel tank capacity directly affects your refueling frequency. My car has a 60-liter tank, requiring refueling twice a month for urban commuting. You should know that manufacturers specify maximum capacity - don't fill it to the brim during normal refueling, leaving some expansion space is safer. There are noticeable differences between brands: German cars generally have larger tanks (like the Passat's 66L), while Japanese cars have smaller but more fuel-efficient tanks. I've developed a rule of thumb: multiply tank capacity by 0.8 for actual usable volume, since the fuel pump can't access the very bottom. Also, stop refueling when the nozzle clicks - forcing more fuel can damage the carbon canister.

This depends on the specific model. Most common A-segment cars have 45-55 liters, like the Corolla with 50 liters; B-segment cars fall in the 55-65 liter range, with the Accord around 56 liters. The simplest way to check is to refuel when the fuel light comes on and note how many liters you added. Once when I rented a car, I found the actual capacity was 3 liters less than the manual stated, later learning it was due to empty space from the fuel tank's shape design. Be especially careful with modified cars—a friend added an auxiliary fuel tank and failed the annual inspection as a result.
