18 MPG combined isn’t going to win any awards, but for the 2024 Ford Bronco Black Diamond 4WD 2.3L, it’s almost beside the point. This isn’t a vehicle purchased for efficiency; it’s a tool, a statement, and a ticket to adventure. Buyers of the Black Diamond trim prioritize off-road capability, ruggedness, and the Bronco’s iconic design above all else. If maximizing fuel economy were the goal, they’d be shopping for a Prius, not a body-on-frame 4×4 with a heritage stretching back decades.

City and highway performance

The EPA rates the 2024 Ford Bronco Black Diamond 4WD 2.3L identically for city and highway driving, both at 18 MPG. This peculiar consistency speaks to the Bronco’s aerodynamics (or lack thereof) and the inherent inefficiencies of a four-wheel-drive system, even when operating primarily in two-wheel-drive mode on paved surfaces. Around town, the turbocharged 2.3L EcoBoost engine provides ample torque for confident acceleration, but stop-and-go traffic inevitably takes its toll. On the highway, the boxy shape and knobby tires generate considerable wind resistance, negating any potential fuel savings from cruising at a steady speed.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Ford Bronco Black Diamond 4WD 2.3L at $2,450. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Actual costs will vary depending on individual driving habits and fluctuations in fuel prices. However, $2,450 provides a benchmark for prospective buyers to factor into their ownership budget. While this number might seem alarming to some, it would not deter someone who is shopping for a vehicle with excellent 4×4 capabilities.

Real-world expectations

While the EPA figures are a useful starting point, real-world fuel economy often deviates, especially with a vehicle like the Bronco. Factors such as tire pressure, driving style, terrain, and the use of accessories (roof racks, winches, etc.) can all significantly impact fuel consumption. Owners who frequently engage the four-wheel-drive system, tackle challenging off-road trails, or spend considerable time idling will likely see their MPG numbers dip below the EPA estimates. Conversely, those who primarily use their Bronco as a daily driver on paved roads and adopt hypermiling techniques might be able to eke out slightly better fuel economy. Many drivers use fuel tracking APPs to help manage this accurately.

How it compares

Compared to other off-road capable SUVs, the 2024 Ford Bronco Black Diamond’s fuel economy sits roughly where you might expect. The Jeep Wrangler Unlimited, a direct competitor, achieves a slightly better 20 MPG combined with its 2.0L turbocharged engine and eight-speed automatic transmission. However, the larger, more powerful Toyota 4Runner, with its standard V6 engine, manages only 17 MPG combined. Even the smaller Jeep Cherokee Trailhawk, with its 3.2L V6, only manages 21 MPG combined despite its smaller size and on-paper advantages. For those seeking a more efficient off-roader, a crossover SUV like the Subaru Forester Wilderness achieves 25 MPG combined, but sacrifices some of the Bronco’s ruggedness and off-road prowess. Consider searching BRONCO MPG across all years to get an idea of how fuel economy has evolved on this model.

Tips to maximize efficiency

While prioritizing fuel economy might seem contradictory to the Bronco’s purpose, there are still steps owners can take to minimize fuel consumption without sacrificing the vehicle’s capabilities. Regular maintenance, including tire rotations and air filter replacements, can help optimize engine performance and reduce drag. Ensure that your tires are inflated to the recommended pressure, as underinflated tires increase rolling resistance and reduce fuel efficiency.

Avoid aggressive driving habits such as hard acceleration and braking, which consume more fuel. Anticipate traffic conditions and maintain a steady speed whenever possible. Minimize idling, as it burns fuel without covering any distance. If you’re stopped for more than a brief moment, turn off the engine.

When not actively engaged in off-roading, keep the Bronco in two-wheel drive. Engaging four-wheel drive on dry pavement increases drivetrain friction and significantly reduces fuel efficiency. Only use four-wheel drive when necessary for traction and stability.

Consider the weight of your cargo and accessories. Extra weight puts a strain on the engine and reduces fuel economy. Remove any unnecessary items from the vehicle and avoid adding heavy aftermarket accessories unless they are essential for your intended use.

Finally, exploring alternative routes can often pay dividends in fuel savings. Avoiding congested areas or roads with frequent stop-and-go traffic can help maintain a more consistent speed and reduce fuel consumption.
