The 2023 Ford Mustang HO Convertible 2.3L 4-cyl gets an EPA-estimated 22 MPG combined. While it’s not the most fuel-efficient car, that’s not really the point. Buyers of this Mustang are looking for open-air fun and iconic style at a relatively accessible price. The 2.3-liter High Output EcoBoost engine provides ample power for spirited driving, and the automatic transmission delivers smooth shifts. Fuel efficiency is a secondary concern, and buyers are willing to trade some MPG for the Mustang’s overall experience.

City and highway performance

EPA estimates for the Mustang convertible are 19 MPG in the city and 26 MPG on the highway. The city figure represents typical stop-and-go driving with lower average speeds, which are less favorable for fuel economy. The Mustang’s engine can operate more efficiently on the open road, hence the higher highway MPG. Understanding these numbers allows potential owners to estimate their real-world fuel consumption based on their typical driving. The 10-speed automatic transmission is engineered to optimize engine performance and efficiency across a wide range of speeds, using its many gear ratios to keep the engine in its most efficient operating range.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Ford Mustang HO Convertible 2.3L 4-cyl at $2,000. This is based on driving 15,000 miles per year and using national average fuel prices. Remember this is an estimate, and your actual fuel costs will vary depending on your driving habits, local fuel prices, and specific driving conditions. It does, however, provide a useful benchmark for comparing the Mustang’s operating costs to other vehicles. Careful shoppers can use this data, along with all Ford fuel economy data, to get a sense of running costs.

Real-world expectations

While EPA estimates provide a baseline, real-world fuel economy can differ. Driving style, geographic location, and weather conditions all have an effect. Aggressive acceleration, hard braking, and consistently high speeds will reduce fuel efficiency and smooth, steady driving will help you get closer to the EPA estimates. Pay attention to driving habits because understanding a vehicle requires awareness of its behavior under your own inputs.

How it compares

The 2023 Mustang’s fuel economy is in the middle of the pack compared to other convertibles. The Mazda MX-5 Miata, for example, gets a much higher 29 MPG combined (automatic transmission) and leads the class in fuel efficiency. However, the Miata is much smaller and offers a different driving experience. The BMW Z4 M40i gets a combined 25 MPG with its powerful inline-six engine. That car is priced significantly higher than the Mustang. Potential buyers must weigh the Mustang’s fun-to-drive factor and iconic status against the better fuel efficiency of alternatives.

Tips to maximize efficiency

Avoid rapid acceleration and hard braking. Smooth and consistent acceleration and gentle braking are more fuel-efficient. Anticipate traffic flow and maintain a steady pace when possible.

The Mustang, especially in convertible form, invites spirited driving so resist the urge to constantly rev the engine and enjoy the EcoBoost’s torque in a more measured way.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Regularly check your tire pressure and inflate them to the recommended pressure on the tire placard or in the owner’s manual. Tire pressure is a simple factor that often gets overlooked.

Reduce unnecessary cargo. Extra weight reduces fuel efficiency, impacting the Mustang’s MPG. Removing items you don’t need, especially heavy objects in the trunk, will help maximize your MPG.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy. Avoid unnecessary accelerating and decelerating, and on even highways, it is an easy way to better manage energy.

Keep up with scheduled maintenance. Regular maintenance, such as oil changes and air filter replacements, helps ensure your engine is running efficiently. Follow the recommended maintenance schedule in your owner’s manual, doing so can make a small difference in fuel economy and a big difference in reliability.
