The 2024 Ford Bronco Black Diamond 4WD with the 2.7L EcoBoost V6 gets 18 MPG combined. To be frank, nobody choosing this configuration of the Bronco is prioritizing fuel sippage. This is a purpose-built off-roader, a lifestyle vehicle, and a statement. Fuel economy takes a back seat to capability, strongness, and the sheer fun of open-air motoring. The Black Diamond trim, with its heavy-duty steel bumpers, rock rails, and locking rear differential, is specifically designed for buyers who intend to push their vehicle off the beaten path, and those adventures come at a price.

City and highway performance

What might surprise some is the consistency of the fuel economy numbers. The EPA estimates 18 MPG in the city and 18 MPG on the highway. This suggests the Bronco’s aerodynamics (or lack thereof) become a significant factor even at lower speeds, and the automatic transmission’s programming is aimed at maintaining momentum rather than aggressively targeting fuel conservation. Stop-and-go traffic will likely yield results slightly below the EPA estimate, while steady highway cruising might occasionally nudge slightly higher; however, expect the number “18” to be your reliable companion at the pump.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Ford Bronco Black Diamond 4WD 2.7L to be $2,450. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s important to understand that this is an estimate. Actual fuel costs will vary depending on individual driving habits, local fuel prices, and the type of driving done (e.g., more off-roading will negatively impact fuel economy). Consider this number a benchmark for comparisons to other vehicles and remember that your personal fuel expenses could be higher or lower.

Real-world expectations

While the EPA provides standardized testing, real-world MPG often deviates. Factors such as tire pressure, driving style, aftermarket modifications (lift kits, larger tires), and even the terrain you typically drive on will influence your fuel economy. Bronco owners who frequently engage four-wheel drive, navigate challenging off-road trails, or use their vehicle for towing should anticipate seeing numbers closer to the lower end of the spectrum. Conversely, those who stick to mostly paved roads and maintain a moderate driving style might occasionally exceed the EPA estimates, although not by a significant margin. It’s prudent to track your mileage and fuel consumption to get a more accurate picture of what your individual Bronco achieves.

How it compares

The Bronco’s fuel economy positions it as one of the less efficient vehicles in the mid-size SUV segment. The Jeep Wrangler Unlimited, in a similar configuration with the 3.6L V6, achieves around 19 MPG combined. A Toyota 4Runner, another body-on-frame off-roader, manages about 17 MPG combined. Compared to more mainstream SUVs like the Honda Passport (21 MPG combined) or the Subaru Outback (29 MPG combined with the base engine), the Bronco’s thirst for fuel is evident. However, those vehicles lack the Bronco’s off-road prowess and open-air design; this highlights the trade-offs buyers make when choosing a vehicle with this specific focus. If better fuel economy is a serious concern, buyers might consider the Bronco with the smaller 2.3L EcoBoost engine, which offers slightly improved gas mileage, or explore all all Ford fuel economy data to compare other models.

Tips to maximize efficiency

While the Bronco Black Diamond isn’t designed for optimal fuel efficiency, there are still steps you can take to minimize fuel consumption.

Ensure your tires are properly inflated to the recommended pressure. Lower tire pressure increases rolling resistance thus decreasing fuel economy. It’s a small thing, it’s free, and it’ll boost MPG.

Avoid aggressive acceleration and braking. The Bronco’s hefty weight requires more energy to get moving, so smooth and gradual acceleration will conserve fuel. Anticipate traffic flow and avoid sudden stops whenever possible.

Reduce unnecessary weight. Carrying around extra gear or equipment adds load to the vehicle, which negatively impacts fuel economy. Remove any items that are not essential for your daily driving or off-road adventures. Consider the weight of aftermarket accessories, such as roof racks or storage systems, that influence BRONCO MPG across all years.

Minimize idling. Extended periods of idling consume fuel without covering any distance. If you anticipate waiting for more than a minute or two, turn off the engine. The 2.7L EcoBoost may sound great, but it’s happier and more economical when it’s moving.

Service your Bronco regularly. Keeping the engine properly tuned, the air filter clean, and the fluids topped off will ensure it runs efficiently. Follow Ford’s recommended maintenance schedule to maintain optimal performance and fuel economy.
