2015 Ford Mustang Fuel Economy Drops


Just the Facts:
  • The 2015 Ford Mustang's fuel economy is lower than that of the outgoing model, according to figures just released by the EPA.
  • The 2015 Mustang equipped with the 3.7-liter V6 engine and either a six-speed automatic or manual transmission is officially rated at 28 mpg on the highway.
  • The 2014 Mustang was EPA-rated at 31 mpg in highway driving with an automatic transmission and 29 mpg on the highway with a manual transmission.

DEARBORN, Michigan — The 2015 Ford Mustang's fuel economy is lower than that of the outgoing model, according to figures just released by the EPA.

The 2015 Mustang equipped with the 3.7-liter V6 engine and six-speed automatic transmission is officially rated at 19 mpg in the city and 28 mpg on the highway, while the same model with a six-speed manual transmission returns 17 mpg in city driving and 28 mpg on the highway.

That's a drop of 3 mpg from the 2014 V6 Mustang's highway rating of 31 mpg with the automatic transmission, and one mpg worse than the 2014 model's highway mileage of 29 mpg with a manual transmission. City ratings for the 2014 V6 Mustang were 19 mpg with either transmission.

By comparison, as previously reported by Edmunds, the 2015 Chevrolet Camaro, one of the Mustang's primary competitors, is EPA rated at 19 mpg in city driving and 30 mpg on the highway when equipped with a V6 engine and six-speed automatic transmission and 18 mpg in the city and 27 mpg on the highway with the manual transmission.

The story isn't much different for the 2015 Mustang GT.

Equipped with the 5.0-liter V8 and a six-speed automatic transmission, the 2015 GT model carries an EPA rating of 16 mpg in the city and 25 mpg on the highway, while the six-speed manual transmission version delivers 15 mpg in city driving and 25 mpg on the highway.

That's down from the 2014 Mustang GT's 18/25 city/highway rating with the automatic transmission and 15/26 city/highway mileage with the manual transmission.

The GT's V8 does, however, offset the drop in fuel economy with a gain in power, up from 420 horsepower and 390 pound-feet of torque in 2014 to 435 hp and 400 lb-ft of torque for 2015.

By comparison, the 2015 Chevrolet Camaro SS, with the 6.2-liter V8 that produces 426 hp and 420 lb-ft of torque, is EPA rated at 16 mpg in city driving with a six-speed manual transmission and 15 mpg in the city with a six-speed automatic. Both Camaro transmissions deliver 24 mpg on the highway.

Not surprisingly, the best fuel economy in the 2015 Mustang range is produced by the 2.3-liter turbocharged four-cylinder EcoBoost engine. Equipped with the six-speed automatic transmission, the EcoBoost model — new to the Mustang lineup — is rated at 21 mpg in city driving and 32 mpg on the highway. With the manual transmission, that same engine delivers 22 mpg in the city and 31 mpg on the highway.

Word of the 2015 Mustang's fuel economy numbers comes at a time when gasoline prices have dipped. The AAA Daily Fuel Gauge Report on Monday pegged the average price for a gallon of unleaded gasoline at $3.39 versus $3.52 a year ago.

Edmunds says: While the redesigned 2015 Ford Mustang provides updated styling and enhanced features, those improvements comes at a slight cost in fuel economy.
