2015 Ford Mustang GT: Fuel Economy Update for July - A Coastal Tour and Burnouts

August 7, 2015

2015 Ford Mustang GT

We put 1,678 miles on our 2015 Ford Mustang GT in July, using 110.7 gallons of 91-octane fuel. For the month we averaged just 15.2 mpg, which dropped our lifetime fuel economy from 16.3 to 16.1 mpg.

Our worst fill-up for the month was 11.0 mpg and our best was 19.9, neither one of them records.

As you should with a Mustang GT, we had some big-time fun during the month. Senior Editor Josh Sadlier took a two-day coastal drive to Monterey and back, putting 650 miles on the car. He even managed a new best range of 301.3 miles on a single tank of fuel.

The Mustang GT also served as the training tool to see if our boss, Edmunds.com CEO Avi Steinlauf, could do a burnout. Turns out, he can.

Worst Fill MPG: 9.5
Best Fill MPG: 23.5
Average Lifetime MPG: 16.1
EPA MPG Rating: 19 Combined (15 City/25 Highway)
Best Range: 301.3 miles
Current Odometer: 12,210 miles
