Ford Announces 2018 Mustang Fuel Economy Figures

Earlier this month, a window sticker for the 2018 Ford Mustang GT with the new 10-speed automatic leaked the fuel economy for the newest V8 Mustang with the new transmission and as we expected, MPGs are up. Today, Ford Motor Company has announced their estimated fuel economy numbers for the 2018 Mustang in both EcoBoost and GT form and with both available transmissions – with improvements in almost every category.

2018 Ford Mustang EcoBoost Fuel Economy
First up, we have the numbers for the 2018 Ford Mustang EcoBoost, which delivers the same 310 horsepower as the 2017 version, but with 350lb-ft of torque, the new turbocharged pony car has 30 extra pound-feet of torque. Even with that extra power, the enhanced aerodynamics of the 2018 Mustang design coupled with the new 10-speed automatic transmission leads to an increase in fuel economy figures.

Even with the 6-speed manual, the 2018 Ford Mustang EcoBoost offers slightly better fuel economy, with 21mpg in the city, 31mpg on the highway and 25mpg combined. Compared to that same drivetrain configuration in 2017, the 2018 Mustang EcoBoost gets 1mpg better on the highway and combined. With the new 10-speed automatic transmission, the 2018 EcoBoost Mustang is expected to see 21mpg around town, 32mpg on the highway and 25mpg combined, so the city number remains the same while highway efficiency improves by 2mpg and the combined number improves by 1mpg.

While some may have expected a larger increase in fuel economy numbers from the 2018 Ford Mustang EcoBoost with the 10-speed automatic, the combination of more torque and greater fuel economy measures will most certainly appeal to those looking to get into the new “base” Mustang.

2018 Ford Mustang GT Fuel Economy
The 2018 Ford Mustang GT receives a significant increase in power for the new model year, with 460 horsepower and 420lb-ft of torque compared to 435hp and 400lb-ft of torque in the 2017 Mustang GT. Even with that big jump in horsepower and torque, the 2018 Mustang GT is more fuel efficient – at least when fitted with the new 10-speed automatic transmission.

The 2018 Ford Mustang GT with the manual transmission is expected to deliver 15mpg around town, 25mpg on the highway and 18mpg combined – all of which are the same as the 2017 Mustang GT with three pedals. Basically, the aerodynamic improvements allowed Ford to add power while maintaining the same fuel economy numbers.

The 2018 Ford Mustang GT with the new 10-speed automatic transmission also offers the same increase in power, but thanks to the new gearbox, this 2018 Mustang gets slightly better fuel economy. With estimated figures of 16mpg in the city, 25mpg on the highway and 19mpg combined, the 2018 Mustang GT with the automatic transmission is 1mpg better than the 2017 Mustang GT with the old 6-speed automatic in every category.

Again, these are Ford’s estimated fuel economy numbers, but when the EPA announces their official ratings for the 2018 Ford Mustang in EcoBoost and GT form, we can expect that the numbers will be at least this good. It has become rare for an automaker’s estimated numbers to be higher than the EPA figures, but there have been more and more cases where the estimates are lower than the numbers from the EPA – which is what will be used for marketing and on the window sticker.
