What is the maximum fuel tank capacity of a car?

[LeCollin]

Household sedans have a maximum empty fuel tank capacity of 50 liters, compact cars have 40 liters, while SUV models feature 58-liter tanks. The fuel tank volume determines the driving range - for two vehicles with identical engines, the one with a larger tank can travel farther. For heavy-duty trucks, the tank capacity ranges between 80 to 150 liters depending on load capacity. Below are additional details: 1. The rated capacity marked on automotive fuel tanks, as specified in the manufacturer's manual, considers vehicle safety and fuel's thermal expansion/contraction characteristics. Designers always leave some extra space in the tank. 2. According to China's mandatory national standard GB18296-2001 "Safety Performance Requirements and Test Methods for Automotive Fuel Tanks", the nominal capacity should be controlled at 95% of the tank's maximum safe capacity, typically representing 80% to 90% of full capacity. This measurement excludes the fuel line volume between the tank and filler neck, as well as the pipeline from engine to tank bottom.
