Since Ford Motor Company confirmed that the 2015 Mustang would be fitted with a new 2.3L EcoBoost 4-cylinder, we have speculated that the next gen pony car would be the most efficient option in the segment. Neither Ford Motor Company nor the EPA have offered up the official fuel economy figures for the 2015 Mustang, but thanks to our friends at Mustang6g.com, we have our first look at some of the fuel economy numbers straight from the official Ford window stickers.

We do not have the complete list of 2015 Ford Mustang fuel economy figures, but we see enough to know that the new Mustang EcoBoost will almost surely be the most efficient muscle car on the market today. Thanks to Mustang6g.com, we have our first look at the base model Mustang V6 fastback with both the manual and automatic transmission as well as the Mustang EcoBoost fastback with the 6-speed manual.

2015 Ford Mustang V6 Fuel Economy

The most complete corner of the 2015 Ford Mustang fuel economy puzzle that we have thus far pertains to the base model V6. When mated to the standard 6-speed manual transmission, the 2015 Mustang V6 offers 17 miles per gallon around town, 28 miles per gallon on the highway and a combined figure of 21 miles per gallon. That is actually worse than the 2014 Mustang V6 with the manual transmission that offers 19 around town, 29 on the highway and 22 combined…which should come as no surprise considering that the 2015 Mustang is heavier than the 2014 model.

The 2015 Ford Mustang V6 with the Select Shift 6-speed automatic transmission offers 19mpg around town, 28 on the highway and 22 combined – also worse than the 2014 V6 Mustang that returned 19mpg around town, 31mpg on the highway and 23mpg combined.

In comparison to the 2015 Chevrolet Camaro with the base V6, the manually shifted model offers the same 17 around town and 28 on the highway with a slightly lower 20mpg combined figure. The Camaro V6 with the self shifting transmission offers 18mpg around town, 27 on the highway and 21 combined – giving the Mustang the advantage among V6 models regardless of the transmission chosen. However, those 2015 Camaro V6 buyers who opt for the 2LS with the automatic transmission and the 2.92 rear axle can expect to hit 19mpg around town and 30 on the highway with a combined figure of 22mpg. This gives the Camaro an advantage…but only in that one trimline. Also, the 2015 Dodge Challenger with the 3.6L V6 and the standard 8-speed automatic offers the same 19 and 30 as the Camaro regardless of the trimline chosen so technically, the Challenger is the most fuel friendly of the V6 muscle cars…although the Mustang wins the battle among those models with the manual transmission.

2015 Ford Mustang EcoBoost Fuel Economy

While we only have the fuel economy numbers for the 2015 Ford Mustang EcoBoost with the 6-speed manual transmission, figures of 22 miles per gallon around town, 31mpg on the highway and 26 combined makes the 2015 Mustang the most fuel friendly car in the segment…by a significant amount. There is currently no Chevy Camaro or Dodge Challenger that offers anywhere close to 26mpg combined while the city and highway EcoBoost numbers give this turbocharged 4-cylinder an advantage over the competition.

More importantly, we should keep in mind that the 2015 Ford Mustang V6 with the automatic transmission is more fuel efficient than the same engine with the manual transmission…and the same is true across the entire 2014 Mustang line including the 5.0L V8. Considering that fact, I would most certainly expect to see the 2015 Mustang EcoBoost with the 6-speed automatic transmission offering better fuel economy numbers than the manually shifted models. If we use the fuel economy figures for the 2015 Mustang V6 as an example with 2mpg better around town, the same highway figures and 1mpg better combined figures – the self shifting Mustang EcoBoost could offer 24mpg around town, 31mpg on the highway and 27mpg combined. Those figures would allow the Mustang EcoBoost to very comfortably beat the most efficient 2015 Camaro across every category.

So for now, the 2015 Ford Mustang EcoBoost appears to be the clear winner of the muscle car fuel economy battle while also offering enough power to keep up with the Camaro V6. Hopefully these leaked figures will push Ford to announce the numbers for the rest of the 2015 line very soon.
