What is the fuel tank capacity of the Passat B5 in liters?

The fuel tank capacity of the Passat B5 is 68.5 liters, as officially announced. The Passat B5 requires 95-octane fuel, with a fuel consumption of 5.8-6.7L per 100 kilometers. A full tank can cover a distance of 1022-1181km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level is accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.
I've been driving a Passat B5 for several years, and its fuel tank capacity is around 62 liters, which is quite practical. For daily commutes, a full tank can last for 600 to 700 kilometers, assuming a fuel consumption of 8 liters per 100 kilometers. On weekends, even for long trips, I don’t have to worry about frequently looking for gas stations, especially on highways where the fuel consumption drops to about 6 liters per 100 kilometers, extending the range even further. I still remember a trip with the family, fully loaded with luggage, driving from Shanghai to Hangzhou and back with fuel to spare. The 62-liter design strikes a perfect balance—too large would increase the car’s weight and fuel consumption, while too small would require frequent refueling. Volkswagen did a solid job with the fuel tank in the B5 model; it’s sturdy with no leakage issues. However, for older cars, it’s important to check maintenance records to prevent fuel pump carbon buildup.
From a vehicle engineering perspective, the standard fuel tank capacity of the Passat B5 is 62 liters, as clearly stated in the car manual. The design takes into account space utilization and fuel safety, with the tank positioned in front of the rear axle, a reasonable location that does not encroach on passenger space. Made of thick plastic to prevent rust and leaks, it ensures long-term durability without corrosion. With an average fuel consumption of around 8 liters, the 62-liter capacity supports approximately 700-800 kilometers of driving, making it suitable for family or long-distance needs. Compared to other German cars, the BMW 3 Series has a similar size, proving this design is mature and reliable. However, driving habits affect actual range, so smooth acceleration and avoiding overloading are recommended. Regular checks of the fuel system are advised to prevent blockages.
