The typical modern Honda Civic fuel tank holds about 12.4 gallons. This figure covers most current gasoline Civics, but the exact capacity can vary by model year and body style.
Current-generation capacity
For the latest Civics, Honda generally lists a 12.4-gallon tank for most sedan and coupe configurations. The hatchback and certain trims may differ slightly depending on year and market.
Sedan and coupe
Most sedan and coupe variants use the 12.4-gallon tank, providing a consistent range across trims such as LX, Sport, EX, and Touring. Real-world range depends on engine choice, transmission, and driving style.
Hatchback
The Civic hatchback can show minor variations in tank size compared with the sedan/coupe, typically around 12.0 to 12.4 gallons depending on model year and market. Always check the exact specification for your specific build.
Why tank size varies
Tank capacity is shaped by design goals such as passenger space, weight distribution, and regulatory requirements. As generations evolve, Honda may adjust tank size to balance efficiency, emissions, and overall vehicle packaging. Hybrids or special editions can also influence the tank configuration.
Summary
In most current Honda Civics, plan on a 12.4-gallon gasoline tank as the baseline. If you’re looking at an older generation or a hatchback variant, expect a similar figure with a possible minor difference (roughly 12.0 to 12.4 gallons). Verify the exact spec for your specific model to calculate range accurately.
