2015 Ford Mustang EcoBoost Sets New Fuel Economy Benchmark
Ford's 2.3-litre EcoBoost engine delivers a combined 26 mpg for the 2015 Mustang, outpacing the V6 and awaiting final figures for the V8 GT.
Ford’s 2015 Mustang arrives with a new engine option and a clear focus on efficiency, as the first official EPA fuel economy figures show the 2.3-litre EcoBoost turbocharged four-cylinder returning 26 mpg combined with the six-speed manual gearbox. This places the new EcoBoost model above the V6 in Ford’s own line-up for fuel economy, marking a sharp shift from tradition for the Mustang badge.
2015 Ford Mustang Gas Mileage: A New Era for Efficiency
EcoBoost Engine: Fuel Economy Figures
The 2.3-litre EcoBoost engine is the first four-cylinder to appear in a Mustang since the 1980s, and its 26 mpg combined figure (22 mpg city, 31 mpg highway) with the manual transmission puts it ahead of the entry-level 3.7-litre V6. The V6 manages 21 mpg combined (17 city, 28 highway) with the manual and 22 mpg combined (19 city, 28 highway) when paired with the automatic. Ford has not yet published automatic transmission figures for the EcoBoost, leaving some buyers waiting for a full comparison. The return of a four-cylinder engine to the Mustang lineup signals Ford’s intention to appeal to a wider audience, especially those who prioritise efficiency alongside performance.
| Engine/Transmission | City | Highway | Combined |
|---|---|---|---|
| 2.3L EcoBoost Manual | 22 | 31 | 26 |
| 3.7L V6 Manual | 17 | 28 | 21 |
| 3.7L V6 Automatic | 19 | 28 | 22 |
V8 GT: Awaiting Fuel Economy Ratings
Ford has not yet released EPA ratings for the 5.0-litre V8 GT, which is expected to be the thirstiest in the range. The new Mustang GT is rated at 420 hp and 528 Nm of torque, but buyers will have to wait for official fuel economy numbers. The absence of these figures leaves the EcoBoost as the headline act for efficiency, at least for now. Historically, V8 Mustangs have prioritised performance over economy, so the new EcoBoost’s strong showing marks a notable change in the Mustang’s appeal.
Comparing the Mustang’s Engine Options
The 2015 Mustang’s engine lineup offers buyers a range of choices, each with distinct fuel economy characteristics. The EcoBoost stands out for those seeking the best mileage, while the V6 provides a balance between performance and efficiency. The V8 GT, once its figures are released, is likely to appeal to traditional Mustang enthusiasts who value power above all else. For drivers who prioritise running costs or plan to use their Mustang as a daily driver, the EcoBoost provides a compelling alternative to larger engines. The introduction of the EcoBoost also reflects Ford’s response to changing market demands, especially as fuel prices and emissions regulations become increasingly important factors in car buying decisions.
What the New Figures Mean for Buyers
The EcoBoost Mustang’s 26 mpg combined rating puts it ahead of the V6 in both city and combined driving, offering a more efficient alternative without stepping up to a hybrid or diesel. For buyers, this means lower running costs and a broader choice within the Mustang range. The figures also reflect Ford’s strategy to broaden the Mustang’s appeal in markets where fuel economy is a greater concern, particularly as the EcoBoost will be offered in Europe as well. The 2015 Ford Mustang EcoBoost manual achieves 31 mpg on the highway, the highest figure ever for a factory Mustang at launch. This achievement is significant for the Mustang, a model long associated with high performance rather than efficiency.
Automatic transmission figures for the EcoBoost and the final V8 GT ratings are still pending. As more details emerge, the Mustang’s position in the sports coupe segment will become clearer, especially for buyers weighing performance against running costs. The 2015 Mustang’s improved efficiency could play a role in attracting new customers who might have previously overlooked the model due to concerns about fuel economy. For those considering a Mustang as a daily driver or for longer commutes, the EcoBoost’s numbers are likely to be especially appealing.
Looking Ahead: Mustang’s Broader Appeal
The shift in the Mustang’s engine lineup and the improved gas mileage figures reflect larger trends across the automotive industry, as manufacturers respond to consumer demand for vehicles that offer both performance and efficiency. The 2015 Mustang’s EcoBoost engine is a clear indication that Ford is aiming to keep the Mustang relevant in global markets, including Europe, where fuel economy standards are stricter and buyers are more conscious of running costs. As the full range of fuel economy figures becomes available, buyers will have more information to help them choose the Mustang that best fits their needs.
