29 MPG combined is a respectable figure for the 2017 Ford Mustang EcoBoost, and it’s exactly the fuel economy this model needed. It’s not trying to lure hypermilers away from their Priuses, but for those who want iconic styling and rear-wheel-drive fun without the V8 guzzler, this EcoBoost version provides a compromise of performance and relative efficiency. More than anything, this is a lifestyle choice with a reasonable fuel bill attached.

City and highway performance

The 2017 Mustang EcoBoost, equipped with the 6-speed automatic transmission, earns an EPA rating of 26 MPG in the city and 34 MPG on the highway. The city number reflects the reality of stop-and-go traffic, which is the bane of any turbocharged engine’s efficiency. The engine needs to spool up the turbo to deliver its power. Expect to see that number drop even further with a heavy foot. Highway driving allows the engine to settle into its most efficient range, where the turbocharger isn’t constantly engaged, resulting in a much better MPG figure. Those long stretches of open road are where the EcoBoost truly shines, proving that a sporty car can also be reasonably efficient.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2017 Ford Mustang EcoBoost is $1,810. This estimate is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is just an estimate; your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and where you live. Premium fuel is recommended for optimal performance in the Mustang EcoBoost, although it’s not strictly required. You could use regular unleaded, but it may result in a slight decrease in power and fuel economy, so keep that in mind when calculating your own fuel spending.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world fuel economy often differs. The Mustang EcoBoost is particularly sensitive to driving style. Those who frequently unleash the car’s 310 horsepower will see their MPG suffer. Conservative drivers who prioritize smooth acceleration and consistent speeds can realistically match or even exceed the EPA’s estimates, especially on long highway trips. However, spirited driving and heavy city congestion can easily drop the average MPG into the low 20s. The EcoBoost’s versatility allows it to deliver good fuel economy when driven responsibly, and it offers rewarding performance when you want it.

How it compares

The 2017 Mustang EcoBoost’s 29 MPG combined aligns it closely with other sporty coupes. For example, the 2017 Chevrolet Camaro with its base 2.0L turbo engine achieves a similar 25 MPG city and 34 MPG highway with the automatic. The Nissan 370Z, at 18 MPG combined, reveals the fuel penalty buyers accept for naturally aspirated V6 power. Even within the Mustang lineup, checking MUSTANG MPG across all years shows a stark contrast between the EcoBoost and the GT. The V8-powered Mustang GT from the same year delivers a noticeably lower 19 MPG combined, making the EcoBoost a clear choice for those prioritizing fuel efficiency. Shoppers looking for all Ford fuel economy data will see this pattern: EcoBoost offers a substantial MPG gain compared to larger engines across the brand’s model range. It’s a key part of the EcoBoost engine range’s appeal.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the EcoBoost Mustang. Avoid aggressive starts and hard braking, as these actions force the turbocharger to work harder and consume more fuel. Imagine you’re driving with an egg under the accelerator pedal. Smooth and consistent inputs will yield the best results.

Use cruise control on the highway whenever possible. Maintaining a constant speed minimizes unnecessary acceleration and deceleration, resulting in significant fuel savings. This allows the Mustang to stay in its most efficient range, maximizing gas mileage on long trips.

Ensure your tires are properly inflated. Under-inflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended levels listed in your owner’s manual or on the sticker inside the driver’s side door.

Consider modifying your routes to avoid stop-and-go traffic. Taking a slightly longer route with fewer intersections and less congestion can save you fuel in the long run. Planning your trips ahead of time and using navigation apps to identify traffic delays can help you optimize your fuel efficiency.

Reduce unnecessary weight. Carrying extra cargo in your trunk or back seat can negatively impact fuel economy. Remove any items you don’t need to lighten the load and improve your MPG. Every pound counts, especially in a car designed for performance.
