20 MPG combined isn’t exactly cause for celebration, but for the 2023 Ford Bronco 4WD with the 2.3L EcoBoost engine, it’s a reasonable trade-off. This isn’t a vehicle designed for maximizing mileage on the interstate. It’s built for off-road adventures, weekend explorations, and turning heads. Bronco buyers typically prioritize capability and unmistakable style over outright fuel efficiency. They want that rugged look and the confidence a capable 4×4 provides, even if it means a few more trips to the pump.

City and highway performance

The EPA estimates the Bronco 4WD with the 2.3L four-cylinder and automatic transmission at 20 MPG in the city and 21 MPG on the highway. These figures are fairly close, suggesting the Bronco’s fuel consumption is relatively consistent regardless of driving environment. The modest difference between city and highway MPG also reflects the Bronco’s inherent design. Its aerodynamics are compromised by its boxy shape and high ground clearance, impacting highway efficiency more than a traditionally shaped SUV. Its off-road tires contribute increased rolling resistance at all speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Ford Bronco 4WD 2.3L at $2,200. This calculation is based on driving 15,000 miles per year and using the national average fuel price at the time of testing. Remember that this figure is an estimate. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and where you live. Someone who does mostly city driving, or lives in an area with higher fuel prices, will likely exceed the $2,200 estimate, while someone who drives mostly highway miles and lives in an area with lower fuel prices might spend less. Before buying, research all Ford fuel economy data to see the broader picture.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can often deviate. Bronco owners often report figures that are slightly below the EPA’s combined estimate. This is primarily due to aggressive driving styles, off-road use (which significantly impacts fuel consumption), and the addition of aftermarket accessories like larger tires or roof racks. The Bronco encourages exploration, and exploration rarely comes with optimal fuel efficiency. Expect high teens if you do lots of off-roading or have extensive modifications. Many owners accept this knowing the off pavement capabilities they receive in return.

How it compares

Compared to other off-road-oriented SUVs, the Bronco’s fuel economy is generally in line with expectations. The Jeep Wrangler Unlimited 4WD with the 2.0L turbo engine achieves a similar 20 MPG combined. The Toyota 4Runner, with its less efficient V6, manages only 17 MPG combined. The Land Rover Defender 110 with the P300 engine offers slightly better numbers at 19 city / 22 highway, but comes at a significantly higher price point and with a different focus on luxury. For truck-based SUVs, consider the Chevy Colorado, which is slightly better at 22 combined MPG with its base engine. The Bronco slots in with vehicles in its class, though you should always research BRONCO MPG across all years for more information.

Tips to maximize efficiency

While the Bronco prioritizes off-road capability over fuel efficiency, there are still steps you can take to improve your mileage. Avoid aggressive acceleration and maintain a steady speed on the highway. The 2.3L EcoBoost engine responds well to smooth, consistent throttle inputs.

Ensure your tires are properly inflated to the recommended pressure. Under-inflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly, especially before long trips.

Consider the weight you’re carrying. Remove any unnecessary cargo from your Bronco to reduce its overall weight. Extra weight forces the engine to work harder, leading to increased fuel consumption.

Minimize idling. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and prolonged idling wastes fuel.

Be mindful of aftermarket accessories. While roof racks, larger tires, and other modifications can enhance the Bronco’s appearance and functionality, they can also significantly reduce fuel economy. Choose accessories wisely and consider their impact on aerodynamics and weight.
