2015 Ford Mustang GT: Fuel Economy for December
January 8, 2015
We started tracking fuel economy in our 2015 Ford Mustang GT in mid-December with 171 miles on the odo. Since then, it's been easy sailing as we nurse this big V8 through its break-in procedure. No hard driving. No high revs. Should be a slam-dunk to hit the EPA's 19 mpg combined (15 city / 25 highway) rating. Right?
Worst Fill MPG: 11.6 mpg
Best Fill MPG: 14.5 mpg
Average Lifetime MPG: 12.3 mpg
EPA MPG Rating: 19 Combined (15 City/23 Highway)
Best Range: 178.4 miles
Current Odometer: 670.9 miles
It's still early, though. January's already got a trip to Vegas in the books and with no more restrictions on how hard we can rev it, I'm sure the fuel economy will only get better.
