How many gallons is a Chevy Sonic gas tank?
The Chevy Sonic's gas tank capacity is 12.0 gallons (about 45.4 liters).
Across most model years and body styles (sedan and hatchback), Chevrolet cited a 12.0-gallon tank. That fixed capacity influences how far you can go between fills and how often you refuel on a trip, making it a key detail for buyers, owners planning long drives, or those budgeting fuel expenses.
Model-year consistency
Fuel-tank size remained steady across the Sonic's US market run, with official specifications listing 12.0 gallons for both primary body styles. There are no widely documented changes to the tank capacity that would affect most owners.
Estimating driving range
To estimate range, multiply the tank capacity by the vehicle’s fuel economy. The Sonic's economy varies by engine and transmission, but owners commonly report mid- to high-20s mpg in city driving and mid-30s mpg on the highway. A full tank therefore translates into a practical range that generally covers several hundred miles, depending on driving conditions and trim.
Summary
The Chevy Sonic generally uses a 12.0-gallon gas tank, providing a practical balance of range and efficiency for this subcompact. For the exact value on a specific vehicle year and trim, consult the owner's manual or the EPA window sticker.
