The 2020 Ford Mustang HO Convertible with the 2.3L EcoBoost engine gets 23 MPG combined. Nobody buys this car to save on gas like a Prius. They buy it for open-air thrills, iconic styling, and the turbocharged power that Ford’s high-output four-cylinder delivers. The fuel economy is simply a factor to be managed, not the main reason to buy it.

City and highway performance

The EPA estimates that the 2020 Mustang HO Convertible achieves 20 MPG in the city and 27 MPG on the highway. The city figure reflects how responsive the engine is in stop-and-go traffic, where quick bursts of acceleration are typical. The highway MPG, while better, shows that even at steady speeds, the aerodynamics of a convertible and the performance-oriented tuning of the engine affect fuel efficiency. This isn’t a car designed for long trips, it’s a car designed for shorter, spirited drives, and the fuel economy reflects that.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2020 Ford Mustang HO Convertible 2.3L is $1,900. This figure is based on driving 15,000 miles per year and using the national average fuel price when calculated. It’s a useful benchmark for comparing running costs with other vehicles. Remember that your actual fuel expenses will vary depending on your driving habits and local fuel prices. If you’re spending more time with the top down, enjoying the Mustang’s performance, that annual figure will probably be higher.

Real-world expectations

While the EPA ratings provide a standardized comparison, real-world fuel economy often differs. Owners who frequently use the engine’s turbocharger or spend a lot of time in city traffic may see numbers closer to the 18-22 MPG range. On the other hand, those who primarily use the Mustang for highway cruising with a light foot might achieve numbers closer to, or even slightly exceeding, the EPA’s 27 MPG estimate. The key is understanding your driving style and adjusting accordingly to get the most out of each gallon.

How it compares

Competitors like the Mazda MX-5 Miata offer better fuel economy, boasting 29 MPG combined with its automatic transmission. However, the Miata caters to a different audience, prioritizing nimble handling and pure driving feel over outright power. Even the V6-powered Chevrolet Camaro Convertible manages around 22 MPG combined, which puts the turbo Mustang very close despite its smaller engine.

Tips to maximize efficiency

Pay close attention to tire pressure. Ensuring your tires are properly inflated reduces rolling resistance, which directly translates to improved fuel economy. Check your tire pressure regularly, especially during seasonal temperature changes.

Avoid aggressive acceleration and braking. The Mustang invites spirited driving, but excessive use of the throttle and brakes wastes fuel. Instead, practice smooth and gradual acceleration and anticipate traffic flow to minimize braking.

Use cruise control on the highway. Maintaining a consistent speed on long drives prevents unnecessary fluctuations in fuel consumption. Use cruise control if possible to improve efficiency on the open road.

Consider using premium fuel. While the 2.3L EcoBoost engine doesn’t strictly require premium fuel, some owners report slightly improved performance and fuel economy when using it. Experiment to see if premium fuel makes a noticeable difference in your Mustang’s efficiency.

Minimize idling. Leaving the engine running while stationary consumes fuel without covering any distance. If you anticipate being stopped for more than a minute, shut off the engine to save fuel.
