The average ambient temperature while driving the Model Y on our loop was 62 degrees F. It shouldn’t have had much, if any, negative effect on the Model Y’s range capability. In general, the farther away the ambient temperature is from an ideal 70 degrees F, the more a vehicle’s range may be affected.
It’s worth noting that Tesla advises against charging to 100% on a daily basis for the sake of battery longevity. Full charges should be reserved for when you anticipate a longer drive ahead. But for testing purposes, Edmunds will always charge to 100% to determine the car’s maximum potential.
But How Much Did Those 317 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, what can Model Y owners expect to pay at “the pump”? After charging the battery back to full, we calculated an Edmunds consumption rate of 26.2 kWh/100 miles, which is 3.0% more efficient than the EPA estimate of 27 kWh/100 mi. That means that if we lived in Hawaii our 317-mile jaunt in the Tesla would have cost us $27.41, whereas if we lived in Oklahoma, that same charge would cost just $7.39.
