The 2017 Ford Mustang equipped with the 2.3L EcoBoost engine and the Performance Package gets 23 MPG combined. To be clear, nobody buys this Mustang primarily for its gas mileage. The 2.3L turbo is about providing a respectable compromise between performance and daily usability. Think of it as the sweet spot for enthusiasts who want Mustang attitude without V8 thirst.

City and highway performance

The EPA estimates the 2017 Mustang 2.3L Performance Package gets 20 MPG in the city and 28 MPG on the highway with the automatic transmission. The difference between city and highway figures reflects how the EcoBoost engine works. The turbocharger needs to spool up to deliver power, which impacts efficiency in stop-and-go conditions. Out on the open road, the engine settles into a more efficient cruise, taking advantage of the Mustang’s aerodynamic profile. Those highway numbers certainly aren’t bad. The optional automatic transmission, with its 6 speeds, helps here.

Annual fuel cost

According to the EPA, the annual fuel cost for this Mustang configuration is $1,900. This calculation is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway, using the national average fuel price at the time of calculation. Keep in mind that fuel prices fluctuate, and individual driving habits will significantly impact your actual fuel expenses. If you primarily drive in heavy traffic, expect to exceed that $1,900 figure. Conversely, a driver who frequently logs highway miles might see a lower annual cost, even when factoring in the cost of premium fuel.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy often varies. Aggressive driving, frequent short trips, and even tire pressure can all affect the numbers you see on your instrument cluster. Mustang owners who prioritize performance and enjoy the car often report figures slightly below the EPA estimates.

Consistently exceeding 28 MPG on the highway requires a conscious effort to maintain a steady speed and anticipate traffic flow. In day-to-day driving around town, duplicating the 20 MPG city estimate can be a challenge, especially if you frequently tap into that turbo power.

How it compares

The 2017 Mustang 2.3L Performance Package’s fuel economy sits in an interesting space within the sports car segment. Consider the Chevrolet Camaro with its base 2.0L turbo; it offers slightly better EPA numbers at 22 MPG city and 31 MPG highway in automatic guise, potentially appealing to those seeking marginal gains in efficiency. On the other end of the spectrum, a V8 Mustang GT prioritizes outright performance, sacrificing fuel economy considerably, coming in at around 15 MPG city and 25 MPG highway. Even within the Mustang lineup, variations exist; a 2017 Mustang EcoBoost without the Performance Package might achieve slightly better fuel economy due to its less aggressive gearing and aerodynamic elements. Someone considering the 2.3L Turbo with the Performance Package understands these trade-offs. They are willing to sacrifice a few MPGs for enhanced handling and a more engaging driving experience.

Tips to maximize efficiency

Take it easy on the accelerator pedal. The 2.3L EcoBoost delivers strong acceleration, but every aggressive launch cuts into fuel economy. Smooth, gradual acceleration is key. Avoid abrupt starts and stops, and try to anticipate traffic conditions to maintain a consistent speed.

Check tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Keep your tires inflated to the recommended pressure listed on the driver’s side doorjamb. A simple tire pressure gauge can save you money and increase tire life.

Minimize idling. Letting your Mustang idle for extended periods wastes fuel. If you anticipate a wait of more than a minute or two, turn off the engine. Modern vehicles are designed to restart quickly and efficiently, even with stop-start systems disabled, which are not equipped on this model.

Use cruise control on the highway when appropriate. Cruise control helps maintain a consistent speed, which can improve fuel economy on long highway drives. Use cruise control on flat stretches of road and disengage it when encountering hills or heavy traffic that requires frequent speed adjustments.

Keep the car properly maintained, including regular oil changes. This is just common sense. Clean oil reduces friction inside the engine, improving efficiency. Use the manufacturer-recommended oil type and change it according to the recommended service intervals. You can explore all Ford fuel economy data and find more about MUSTANG MPG across all years.
