19 MPG combined is the fuel economy of the 2015 Ford Mustang GT. While this might seem low in a world with hybrid SUVs and electric crossovers, this number is a conscious choice for the experience a naturally aspirated V8 muscle car delivers. Mustang GT owners accept this number, prioritizing power, sound, and classic American performance. They want to feel the road and hear that iconic rumble, and they’re willing to pay for it.

City and highway performance

The 2015 Mustang GT’s MPG is 16 MPG in the city and 25 MPG on the highway when equipped with the 6-speed automatic transmission. The city mileage reflects the engine’s fuel consumption in stop-and-go traffic, where acceleration and idling matter. The highway number is better, but it still lags behind smaller turbocharged engines. Drivers can expect the highway figure to change depending on driving style and cruise control. High speeds will affect the MPG, while a highway cruise can help achieve the EPA estimate.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2015 Ford Mustang GT is $2,763. This is based on driving 15,000 miles per year and using the national average fuel prices during testing. This number can change depending on gas prices, driving type, and driving style. If you drive in the city, or accelerate often, expect annual fuel costs to exceed the EPA estimate.

Real-world expectations

EPA estimates are a benchmark, but real-world MPG for the 2015 Mustang GT can vary. Drivers who drive hard, participate in track days, or modify the car for more horsepower can expect lower fuel economy. Careful drivers might see mileage close to the EPA estimates, but most owners aren’t hypermilers. The car encourages aggressive driving, and many owners report combined MPG in the low to mid teens.

How it compares

The 2015 Mustang GT is in the middle regarding fuel economy, reflecting its performance. A 2015 Chevrolet Camaro SS with the 6.2L V8 and automatic transmission gets 19 MPG combined. A Dodge Challenger R/T Scat Pack, with a 6.4L Hemi, also gets 18 MPG combined. A 2015 Ford Mustang EcoBoost, with its 2.3L turbocharged four-cylinder, gets 25 MPG combined. EcoBoost buyers want fuel efficiency and performance, while GT buyers want V8 power.

Tips to maximize efficiency

First, avoid hard acceleration. The Mustang GT’s V8 can burn fuel during hard acceleration. Gentle acceleration can help fuel consumption, especially in city driving.

Second, check your tire pressure. Underinflated tires increase rolling resistance, which makes the engine work harder and consume more fuel. Inflate your tires to the pressure on the driver’s side doorjamb. This can improve your MPG and extend tire life.

Third, use cruise control on the highway. Maintaining speed minimizes acceleration and deceleration, helping you achieve better fuel economy. Avoid speeding, as fuel consumption increases at higher speeds.

Fourth, avoid idling. If you’re stopped for more than a minute, turn off the engine. Modern engines restart easily and idling consumes fuel. This can save fuel over time, especially in urban areas.
