24 MPG combined is what you can expect with the 2.3L EcoBoost four-cylinder in the modern Mustang. While not groundbreaking, this fuel economy figure is a compromise. Ford offers the EcoBoost Mustang to attract buyers who want the Mustang’s iconic style and sporty driving, but also need everyday practicality. It’s for the young professional who wants a fun weekend car and a presentable daily driver, or the empty-nester who wants some style without sacrificing too much at the pump.

City and highway performance

The EPA estimates 21 MPG in the city and 31 MPG on the highway for the 2023 Ford Mustang EcoBoost with the 10-speed automatic transmission. Remember these are estimates, achieved under controlled conditions. The city MPG reflects stop-and-go traffic, while the highway MPG simulates steady-speed cruising. Your real-world results will vary depending on your driving style, traffic conditions, and even the weather. A heavier foot will drastically reduce both city and highway figures, while consistently adhering to speed limits on long highway stretches could potentially exceed the EPA’s estimate. Those prioritizing fuel economy will spend more time in gentle acceleration and less time enjoying the turbocharged engine’s readily available power.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Ford Mustang 2.3L EcoBoost at $1,800. This figure is based on driving 15,000 miles per year and using the national average fuel price. It’s a useful benchmark for comparing the Mustang’s running costs against other vehicles. Keep in mind that fuel prices fluctuate significantly, and your actual annual fuel expense will depend on where you live and how you drive. Fuel prices also vary depending on the grade of fuel used, and while the 2.3L EcoBoost Mustang is often quoted as taking regular fuel, fuel economy may increase negligibly with premium fuel.

Real-world expectations

While the EPA’s figures provide a standardized comparison, the real-world fuel economy of the 2023 Ford Mustang EcoBoost will vary. Expect to see numbers closer to the combined figure in mixed driving conditions. Aggressive acceleration, frequent braking, and extended idling will all negatively impact fuel efficiency. Owners who prioritize fuel economy and drive conservatively may see averages closer to the highway MPG, while those who frequently tap into the engine’s power will experience significantly lower numbers. The Mustang’s sporty character encourages spirited driving, which often leads to lower fuel economy than advertised. Check out MUSTANG MPG across all years to get a sense of what owners report.

How it compares

Compared to its direct competitors, the Mustang EcoBoost’s fuel economy is generally competitive. The Chevrolet Camaro 2.0T, for example, is rated at 25 MPG combined with the automatic transmission. The Dodge Challenger, which is now discontinued, offered a V6 version closer to the Mustang’s performance and dimensions, getting 23 MPG combined. These minor differences are unlikely to be a deciding factor for most buyers in this segment. Those seeking dramatically better fuel economy might consider hybrid or electric vehicles, but they’d be sacrificing the Mustang’s distinctive muscle car persona.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the Mustang EcoBoost. Avoid aggressive launches and rapid acceleration, as these actions consume significantly more fuel. The EcoBoost engine delivers ample power at lower RPMs, so there’s no need to constantly push it to the redline.

Proper tire inflation is essential for optimal fuel efficiency. Check your tire pressure regularly and maintain it at the recommended level, which can be found on the driver’s side doorjamb or in the owner’s manual. Underinflated tires increase rolling resistance, which reduces fuel economy.

Reduce unnecessary weight in your vehicle. Remove any heavy items that are not needed, such as tools, sports equipment, or other cargo. The lighter the vehicle, the less fuel it will consume.

Plan your routes to avoid stop-and-go traffic. Idling consumes fuel without covering any distance. If you know you’ll be stuck in traffic for an extended period, consider turning off the engine. Minimizing time spent sitting in traffic will improve overall fuel economy. You can also check all Ford fuel economy data.
