18 MPG combined places the 2025 Ford Bronco Sasquatch 4WD 2.3L 4-cylinder in the territory of dedicated off-roaders, a figure that makes perfect sense to its target audience. This isn’t a suburban commuter, nor does it pretend to be. This is a vehicle built for adventure, for traversing formidable trails, and for those who inherently understand that extreme capability often comes with a trade-off in fuel efficiency. The Sasquatch package, with its 35-inch tires, increased lift, and wider stance, is engineered for maximum articulation and obstacle clearance. The 2.3L EcoBoost four-cylinder, while surprisingly potent with 300 horsepower and 325 lb-ft of torque on premium fuel, is tasked with moving a substantial amount of mass and overcoming considerable rolling resistance from that aggressive rubber. For the avid off-roader, the 18 MPG isn’t a deterrent; it’s a known quantity, fully accepted in the quest for unparalleled all-terrain prowess.

City and highway performance

In city driving, the 2025 Bronco Sasquatch 2.3L delivers 17 MPG and 19 MPG on the highway. In city conditions, the large tires and the strong four-wheel-drive system are constantly working, demanding more fuel. Stop-and-go traffic forces the engine to repeatedly overcome the inertia of this heavy vehicle, and the wide, knobby tires inherently create more friction. On the highway, the story is largely similar. While maintaining a steady speed is generally more efficient, the Bronco Sasquatch’s aerodynamic profile, which is essentially that of a brick, and those massive tires working against the wind, mean that highway efficiency doesn’t climb dramatically. This isn’t a vehicle engineered for laminar flow or low coefficient of drag; it’s designed to punch through headwinds and over obstacles. The automatic 10-speed S10 transmission does an admirable job of keeping the engine in its power band and optimizing gear selection for both acceleration and cruising, but even its gearing can only mitigate so much of the inherent aerodynamic and rotational drag.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,450 for the 2025 Ford Bronco Sasquatch 4WD 2.3L 4-cylinder. This figure is calculated based on an average driving distance of 15,000 miles per year, with a mix of 55% city and 45% highway driving, using national average fuel prices. For a Bronco Sasquatch owner, this cost is a line item, an expected expense associated with owning a specialized, highly capable off-road machine. This transparent figure underscores the commitment required for this segment. Individuals who purchase this Bronco know they are not buying a vehicle optimized for miserly fuel consumption. They are buying an experience, a level of capability that few other production vehicles can offer, and the annual fuel cost is simply part of that package deal.

Real-world expectations

In real-world driving, owners of the 2025 Bronco Sasquatch 2.3L can generally expect to see figures very close to the EPA estimates. Aggressive driving, frequent use of four-wheel drive modes, and extended high-speed highway travel will likely push those numbers slightly lower. Conversely, light-footed drivers who stick to flatter terrain and avoid prolonged high speeds might eke out an extra MPG or two. However, the nature of the Sasquatch package fundamentally limits its fuel efficiency. The large, heavy tires, the substantial lift, and the less aerodynamic exterior are baked into its design. What you gain in approach angle, departure angle, breakover angle, and sheer presence, you give up at the pump. The expectation for this vehicle isn’t exceptional fuel economy; it’s exceptional capability. Owners prioritize forging their own path, conquering challenging terrain, and the fuel consumption is an accepted part of that journey.

How it compares

When stacked against its primary competitors, the Bronco Sasquatch’s 18 MPG combined is right in line with the segment. The Jeep Wrangler Rubicon with its 2.0L turbo-four and automatic transmission, another dedicated off-roader, also achieves 20 MPG combined (19 City / 20 Highway), a slight edge, but still firmly in the same range of consumption given the similar mission profile. Opt for the more powerful 3.6L V6 in the Wrangler Rubicon, and you’re looking at 19 MPG combined (18 City / 23 Highway). Even the larger, more truck-like Toyota 4Runner TRD Pro, with its older 4.0L V6 and 5-speed automatic, delivers 17 MPG combined (16 City / 19 Highway), a more direct comparison in terms of its less refined powertrain feel. These comparisons are critical because they highlight that the Bronco Sasquatch is not an outlier. These vehicles are designed for a specific, demanding purpose, and their fuel economy reflects the engineering required to meet those demands. Buyers aren’t cross-shopping a Bronco Sasquatch with a Subaru Forester (29 MPG combined); they’re looking at other serious off-roaders where capability, not efficiency, is the leading metric.

Tips to maximize efficiency

Maintaining consistent tire pressure is important, especially with the large Sasquatch tires. Under-inflated tires increase rolling resistance significantly, directly impacting fuel economy. Check them regularly, particularly before longer trips, and ensure they are at the manufacturer’s recommended road pressure, not the lower off-road pressures some enthusiasts might run.

Anticipate traffic flow and avoid aggressive acceleration and hard braking. The 2.3L EcoBoost has plenty of torque, making it easy to accelerate quickly, but modulating your throttle input smoothly and allowing for graceful deceleration will save a noticeable amount of fuel over time.

Consider removing accessories when not needed. Roof racks, auxiliary lights, and other external modifications, while often part of the Bronco aesthetic, create additional aerodynamic drag, particularly at highway speeds. If you’re not using your rooftop tent for a few months, taking it off will make a difference.

Minimize unnecessary weight. While the Bronco Sasquatch is inherently heavy, regularly carrying heavy gear or tools you don’t need adds to the vehicle’s mass, forcing the engine to work harder. A quick declutter can marginally improve your efficiency.

Limit high-speed travel on the highway. Due to its boxy shape and large tires, the aerodynamic drag on the Bronco increases exponentially with speed. Traveling at 65 MPH instead of 75 MPH in areas where it’s safe and practical can significantly improve highway MPG.
