Which Bronco has the best gas mileage?
The 2.3-liter EcoBoost Bronco paired with Ford’s 10-speed automatic transmission is typically the most fuel-efficient option in the lineup, delivering the best highway mpg among trims. Heavier, more powerful variants such as the 2.7-liter EcoBoost V6 and the Bronco Raptor use more fuel.
How fuel economy varies across Bronco configurations
Fuel economy in the Bronco depends on engine choice, drivetrain configuration, tire size, and body style. This section breaks down the main powertrains and how they influence miles per gallon, so buyers can identify the most efficient setup.
Engine options and their impact on mpg
Note: Actual MPG varies with tires, wheel size, roof configuration, and terrain. The following reflects typical EPA estimates for common configurations as of 2024–2025 models.
- 2.3-liter EcoBoost with 10-speed automatic transmission (4x4): generally the most fuel-efficient Bronco, with EPA estimates in the low-to-mid 20s combined depending on tires and trim.
- 2.7-liter EcoBoost V6: noticeably lower fuel economy than the 2.3L, with highway figures typically in the low 20s or upper teens depending on setup.
- Bronco Raptor (3.0-liter twin-turbo V6): among the least efficient, with combined mpg in the teens due to performance-focused tuning.
- 2.3-liter EcoBoost with a manual transmission (where offered): tends to be similar to or slightly lower in efficiency than the automatic, depending on gearing and driving style.
Concluding note: For most buyers, the 2.3L EcoBoost with the automatic transmission represents the best balance of power and efficiency in the Bronco lineup.
Maximizing fuel economy in any Bronco configuration
Beyond engine choice, several practical steps can help you squeeze more mpg from your Bronco, especially on highway trips where efficiency matters most.
- Keep tires inflated to the recommended pressure; underinflation increases rolling resistance and lowers mpg.
- Use the most efficient drive mode for your trip and maintain steady speeds on highways.
- Minimize aerodynamic drag by removing roof racks or heavy exterior accessories when not needed.
- Perform regular maintenance (air filters, oil changes, spark plugs, and emissions controls) to keep the engine operating efficiently.
- Plan trips to minimize idle time and combine errands to reduce total miles driven.
With these practices, drivers can approach the EPA estimates more closely in real-world conditions, regardless of which Bronco they choose.
Bottom line for buyers
If fuel economy is a top priority, the 2.3-liter EcoBoost Bronco with the automatic transmission is the best bet in Ford’s lineup, especially for highway driving. If off-road capability or ultimate power is the priority, higher-performance variants like the 2.7L V6 or the Raptor will deliver more capability at a cost to efficiency. Always check the latest EPA estimates for your exact configuration, including wheel/tire size and roof choices, as these factors can swing mpg by several miles per gallon.
Summary
The best gas mileage among Broncos tends to belong to the 2.3L EcoBoost with the 10-speed automatic, particularly on highway trips where it can achieve the highest efficiency in the lineup. Heavier, more powerful options—the 2.7L EcoBoost V6 and especially the Bronco Raptor—consume more fuel. Real-world mpg depends on tires, roof configuration, and driving habits, so prospective buyers should review the latest EPA ratings for their specific build before purchasing.
