The 2023 Ford Bronco Black Diamond 4WD with the 2.7L EcoBoost V6 gets 18 MPG combined. Let’s be clear: Nobody buying this Bronco is prioritizing fuel efficiency. They are buying reliable capability, a retro look, and the promise of off-road adventure. The low MPG is simply what you pay to get that lifestyle. This trim, with standard features like heavy-duty skid plates and rock rails, focuses on trail ability over fuel savings. A buyer considering a Black Diamond Bronco already knows they are sacrificing efficiency for a specific experience.

City and highway performance

The EPA estimates the Bronco Black Diamond with the 2.7L V6 gets 18 MPG in both city and highway driving. This symmetrical rating reflects the engine’s inefficiency and the Bronco’s aerodynamic challenges. The short gearing and high torque that make it excellent off-road prevent it from excelling on the open road, while the engine’s thirst for fuel doesn’t diminish much in urban environments. Owners can expect consistent fuel consumption regardless of their driving conditions, but don’t expect great numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for this Bronco Black Diamond at $2,450. This figure is calculated based on driving 15,000 miles per year, with a fuel price reflecting the national average for regular unleaded gasoline (as of the EPA’s calculations). Individual expenses may vary depending on driving habits, local gas prices, and the actual miles driven each year. Still, $2,450 is a reasonable baseline to budget for fuel if you plan to purchase this model.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often changes. The Bronco Black Diamond’s boxy shape, knobby tires, and weight contribute to lower-than-rated numbers for many owners. Aggressive driving, especially off-road excursions, will significantly impact fuel consumption. Expect to see numbers potentially dip below 15 MPG if you frequently engage four-wheel drive or drive at higher speeds. On the other hand, conservative drivers who stick primarily to paved roads might achieve figures closer to the EPA’s 18 MPG, but it’s not likely.

How it compares

The Jeep Wrangler Unlimited, a direct competitor, offers a benchmark for comparison. A 2023 Wrangler Unlimited with the 2.0L Turbo engine achieves a combined 20 MPG. The Toyota 4Runner, another popular off-road SUV, manages only 17 MPG combined with its V6 engine. A Land Rover Defender 110 with the P300 engine fares slightly better at 19 MPG combined, but at a higher price. The Bronco Black Diamond’s fuel economy sits near the higher end of the very low fuel economy range for similarly outfitted SUVs, as most buyers are not cross-shopping with more efficient crossovers. If fuel consumption is a primary concern, all Ford fuel economy data reveals much more economical options in their lineup. You can also analyze BRONCO MPG across all years to see historical trends.

Tips to maximize efficiency

Given the Bronco Black Diamond’s limitations, significant gains in fuel economy are unlikely, but small improvements are possible. Avoid aggressive acceleration and maintain a steady speed. The 2.7L EcoBoost engine rewards smooth throttle inputs with slightly better fuel consumption.

Proper tire inflation is critical. Ensure your tires are inflated to the recommended pressure, as indicated on the door jamb sticker. Underinflated tires increase rolling resistance, which directly impacts fuel economy. Consider using a quality tire pressure gauge and checking regularly.

Minimize unnecessary weight by removing any items from the vehicle that are not essential, especially heavy or bulky items. Extra cargo adds strain to the engine, leading to increased fuel consumption.

Plan journeys strategically. Combining multiple errands into a single trip reduces cold starts, which consume more fuel. Opt for routes with less traffic whenever possible to avoid stop-and-go conditions that waste fuel.

Consider the drive mode. While “Eco” mode may not transform the Bronco into a fuel sipper, it can temper throttle response and shift points, encouraging a more conservative driving style. Experiment to see if it makes a noticeable difference in your typical driving.
