How big is a Ford Bronco gas tank?
The typical full-size Ford Bronco uses a 20.0-gallon fuel tank, while the smaller Bronco Sport carries about 18.0 gallons. Exact capacity can vary by model year and trim.
In this article, we break down the standard tank sizes across common Bronco configurations and explain how the capacity influences range and fueling considerations for owners and prospective buyers.
Tank sizes by Bronco variant
The following sizes reflect common configurations for US-market models from 2021 through 2024. Note that special editions or regional variations may differ slightly.
- Bronco (full-size, two- or four-door): 20.0 gallons (75.7 liters)
- Bronco Badlands / Black Diamond / Outer Banks and other full-size trims: 20.0 gallons (75.7 liters)
- Bronco Sport: 18.0 gallons (68.0 liters)
These figures represent standard fuel tanks. Some markets or special packages may list minor variations, but 20.0 gallons for the full-size Bronco and 18.0 gallons for the Bronco Sport are the commonly cited capacities.
Confirming the exact figure for your build
To verify the precise fuel tank capacity for your Bronco, check the owner’s manual, the original window sticker, or the official Ford brochure for your exact trim and year. If you’re unsure, your Ford dealer can confirm the specification using your vehicle identification number (VIN).
Practical implications for range and fueling
Tank size matters, but real-world range depends on several factors, including engine choice, drivetrain, and driving conditions. The Bronco’s fuel economy and off-road usage can noticeably affect how far you can travel on a full tank.
- Engine and drivetrain: A 2.3L EcoBoost four-cylinder versus a larger 2.7L V6 will yield different mpg figures, influencing range between fills.
- Terrain and driving style: Highway cruising generally delivers better mpg than off-road or rugged terrain driving, which reduces range per tank.
- P payload and towing: Carrying cargo or towing can lower fuel efficiency, shortening the practical distance before refueling.
In practice, most drivers will rely on the vehicle’s range display and plan fuel stops accordingly, especially when venturing into remote or off-road areas.
Summary
The Ford Bronco family uses a 20.0-gallon tank in the full-size models and an 18.0-gallon tank in the Bronco Sport. Exact capacity can vary slightly by year, trim, or market, so consult the manual, window sticker, or dealer for your specific configuration. Understanding the tank size helps anticipate range, fueling needs, and how your driving habits and conditions will influence how far you can go between trips to the pump.
