17 MPG combined. Let’s be clear: if fuel economy is your primary concern, the 2021 Ford Bronco Sasquatch 4WD with the 2.7L EcoBoost V6 isn’t even on your radar. This isn’t a commuter; it’s a statement. It’s a purpose-built off-roader designed to conquer trails, not conserve gasoline. The kind of buyer drawn to this particular Bronco variant wants maximum capability from their rig, and they’re willing to pay the price at the pump. This is a niche vehicle for a customer who values trail prowess far more than trips to the gas station.

City and highway performance

The EPA estimates the Bronco Sasquatch at 17 MPG in both city and highway driving. This parity is due to several factors: the aggressive off-road tires, the significant lift, and the Bronco’s overall brick-like aerodynamics. The 2.7L EcoBoost also requires a heavy foot to get things moving, especially at city speeds. Highway cruising is affected by the increased drag and rolling resistance, resulting in similar figures. These numbers reflect the inherent compromises in a vehicle designed for serious off-road use, not optimal fuel consumption. This is not a vehicle that rewards gentle acceleration or aerodynamic efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Ford Bronco Sasquatch 4WD 2.7L at $2,600. This figure is based on driving 15,000 miles per year, with the assumption that 55% of those miles are driven in the city and 45% on the highway. It also uses the national average fuel price at the time of calculation. Depending on your driving habits and local fuel prices, your actual costs could vary. However, $2,600 is a realistic expectation if you consistently drive the average annual mileage. It’s critical to factor this cost into your overall budget when considering a Bronco Sasquatch, especially if you put significant miles on your vehicles.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary significantly. Aggressive driving, off-road excursions, and modifications like larger tires can lower fuel economy considerably. Conversely, careful driving on the highway might yield slightly better results, but don’t expect miracles. Owners report that matching the EPA’s 17 MPG combined is achievable with a conscious effort, but frequent off-road adventures will almost certainly drop the average.

How it compares

The Jeep Wrangler Rubicon, a natural competitor to the Bronco Sasquatch, typically achieves slightly better fuel economy in its standard configuration. The 2.0L turbo four-cylinder Wrangler Rubicon is EPA-rated at 22 MPG combined. However, equipping the Wrangler with larger tires and a lift kit narrows the gap considerably. The Toyota 4Runner TRD Pro, another popular off-road SUV, comes in around 17 MPG combined. See BRONCO MPG across all years for other Bronco comparisons. The Land Rover Defender 110 with the P300 engine is rated at 19 MPG combined. The key takeaway is that these vehicles are all relatively similar in terms of fuel consumption, and the differences are often outweighed by other performance and feature considerations.

Tips to maximize efficiency

While the Bronco Sasquatch isn’t designed for fuel efficiency, there are steps you can take to minimize consumption. Avoid aggressive acceleration and maintain a steady speed whenever possible. The 2.7L EcoBoost is responsive, but heavy throttle inputs significantly decrease fuel economy. Anticipate traffic flow and avoid hard braking.

Ensure your tires are properly inflated. The large off-road tires on the Sasquatch have higher rolling resistance, and insufficient inflation exacerbates this. Check tire pressure regularly and maintain the recommended levels for optimal fuel economy and tire wear.

Minimize unnecessary weight. Removing any extraneous gear from the vehicle reduces the load on the engine and improves fuel economy, however slightly. Every pound counts when you’re trying to squeeze extra miles from a tank.

Consider using “Eco” mode if your Bronco is equipped with it. This mode adjusts the throttle response and shift points to prioritize fuel efficiency over performance. While it might not be ideal for spirited driving, it can subtly improve fuel economy in everyday situations.
