But How Much Did Those 264 Miles Cost?

Although total range is at the top of most people’s minds when it comes to EVs, energy consumption is an important factor as well. This determines how much your miles will cost you. The unit of measurement for consumption, the kilowatt-hour, can be thought of as the EV equivalent of a gallon of gasoline. Just like gas, the price of electricity varies depending where you live. For example, you’ll pay about 8.9 cents per kilowatt-hour in Oklahoma as of this writing, whereas in Hawaii it’ll run you about 33 cents.

So, how did this Mustang Mach-E stack up? After charging the battery back to full, we calculated an Edmunds consumption rate of 29.2 kWh/100 miles, which is 14.1 percent better than the EPA’s estimate of 34 kWh/100 mi. If we lived in Hawaii, our 264-mile run in the Mustang would have cost us $25.44, whereas if we lived in Oklahoma, that same charge would have cost just $6.86.

How does that compare to other EVs? Consider the 2021 Volkswagen ID.4 First Edition, which we measured at 28.8 kWh/100 mi. in our testing. If you traveled the same 264 miles in the VW, it would have cost $6.77 in Oklahoma and $25.09 in Hawaii. We’ll call this one a wash.

Either way, a gasoline-powered rival would have cost significantly more. Running a 2021 Mercedes-Benz GLC 300 for 317 miles on premium fuel would have set us back roughly $47 in Hawaii and $34 in Oklahoma at current prices, assuming we got the GLC 300’s EPA-estimated 25 mpg combined.

Edmunds Says

Our top-ranked luxury EV continues to shine the more we drive it. With 264 miles of real-world range, the Mach-E with the standard-range battery and rear-wheel drive offers a lot at a very compelling price.
