22 MPG combined isn’t going to win any green awards, but for the 2015 Ford Mustang equipped with the 3.7L V6, it’s an acceptable compromise between performance and practicality. This isn’t a Prius competitor. It’s a rear-wheel-drive sports car designed to evoke decades of American muscle, and that V6 provides a healthy dose of the Mustang experience without emptying your wallet at the pump.

City and highway performance

The EPA estimates the 2015 Mustang V6 at 19 MPG in the city and 27 MPG on the highway. The city figure reflects the demands of stop-and-go driving where the engine spends more time idling and accelerating from a standstill. The 27 MPG highway number reflects consistent speed cruising, where the engine operates more efficiently. Of course, aggressive driving habits will significantly impact both figures, but they serve as a good baseline for comparison.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2015 Ford Mustang V6 will be approximately $2,000. This figure is based on driving 15,000 miles per year and using the national average fuel price. Remember that actual fuel costs will vary depending on individual driving habits and prevailing fuel prices in your area. Factors like longer commutes, frequent hard acceleration, and higher local fuel costs will all push that annual figure upward.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world fuel economy often varies. Owners commonly achieve figures close to the EPA estimates with careful driving. However, the temptation to unleash the Mustang’s V6 is strong, and spirited driving will lower fuel economy. Drivers who prioritize fuel efficiency can expect to see numbers closer to the EPA estimates, while those with a heavier foot will likely experience slightly lower MPG. The 2015 Mustang V6 offers a decent balance, and ultimately, fuel economy is tied to driving style.

How it compares

Compared to other sports cars of its era, the 2015 Mustang V6 holds its own. For example, the 2015 Chevrolet Camaro with its standard 3.6L V6 was rated at 18 MPG city and 27 MPG highway, making the Mustang slightly more efficient in city driving. Similarly, the Nissan 370Z, another popular sports car, achieves around 18 MPG city and 26 MPG highway, putting the Mustang’s efficiency in a relatively positive light. Comparing it to its own siblings highlights its position: While the EcoBoost Mustang offered better fuel economy, figures for the GT with its 5.0L V8 typically land around 15 MPG city and 25 MPG highway, making the V6 a sensible choice for those who want sports car thrills without the associated fuel bill. For those interested in comparing all Ford fuel economy data or looking at MUSTANG MPG across all years, resources are readily available.

Tips to maximize efficiency

Keep your tire pressure properly inflated. Underinflated tires create more rolling resistance, forcing the engine to work harder and reducing fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside your driver’s side door.

Drive smoothly and avoid aggressive acceleration. Rapid acceleration consumes significantly more fuel than gradual acceleration. Anticipate traffic flow and maintain a consistent speed whenever possible. Using the cruise control on the highway can also help to improve fuel economy by minimizing throttle variations.

Reduce idling time. Idling wastes fuel. If you’re stopped for more than a minute or two, turn off the engine. Modern vehicles are designed to restart quickly and easily, and reducing idling time can make a noticeable difference in your fuel consumption.

Use the air conditioning sparingly. The air conditioning compressor puts a load on the engine, reducing fuel economy. When possible, use the ventilation system or roll down the windows to cool the cabin. However, at higher speeds, using the A/C may actually be more efficient aerodynamically than driving with the windows down.

Ensure your vehicle is properly maintained. Regular maintenance, such as oil changes and tune-ups, ensures that the engine is running efficiently. A well-maintained engine consumes less fuel and performs better overall.
