Top 10 Most Efficient Electric Cars.
Electric cars, considering the spec that most shoppers fix on first is its EPA-rated range, number determines whether the EV can work
When considering an electric vehicle, the spec that most shoppers fix on first is its EPA-rated range, as that number determines whether the EV can work for your driving needs and habits, the state of public charging in your area and maybe even your climate extremes. But beyond range, you should check the efficiency of the EV you might buy — that is, how many miles the car wrings out of the electricity stored in its battery. It’s worth comparing the efficiency of various EVs on your shopping list just the way you would the efficiency of conventional gasoline vehicles.

Why EV Efficiency Matters
Just as with gasoline, an EV’s fuel efficiency determines how much you’ll spend to go a given distance. While the least efficient EV still is more fuel-efficient than a comparable gasoline vehicle, charging at home is not free, and charging on the road (particularly with DC fast charging) can be expensive. A more efficient EV also can have a smaller, lighter battery to go the same distance.
But unlike with gasoline refueling, an EV’s efficiency also matters in how long you must plug in to add miles of range to your battery — time that could be measured in hours depending on the charger and how many miles you need. While many variables can affect charging time, an EV that’s twice as efficient will add the same miles of range about twice as fast.
EVs do vary widely in efficiency. Just as you can get a gasoline vehicle rated for 20 mpg or 40 mpg, you can find an EV such as the Hyundai Ioniq 6 that uses 24 kWh of electricity to go 100 miles or a version of the Audi E-Tron S that needs 53 kWh to go the same 100 miles. Based on your needs and charging situation, better efficiency might even be worth accepting a little less maximum range. As with horsepower, folks often buy more range than they really need on the theory that you can’t have too much.
Why Kilowatt-Hours Per 100 Miles?
Kilowatt-hours per 100 miles is one measure of EV efficiency, or the amount of electricity consumed to drive a fixed distance, and it appears on the window sticker of new EVs (and on plug-in hybrids for their EV capability). The stickers of conventional vehicles and hybrids list a similar gallons-per-100-miles measure for their gasoline consumption. But both are in smaller type than the more prominent EPA ratings for mpg-e for EVs and mpg for conventional and hybrid cars.
Without getting too down in the weeds, the mpg-e for EVs is the EPA’s theoretical calculation (based on the energy content of gasoline) that attempts to show electric energy fuel economy in a way comparable to gasoline fuel economy for other vehicles. It’s the EPA’s effort to create a number for EVs that it believes more people will understand. The mpg-e rating can be useful to compare energy efficiency among EVs and for an approximate comparison (with variables) with other vehicles’ gasoline fuel economy.
But these numbers are not so useful in comparing what it will cost you to drive one EV versus another — or versus other types of vehicles — in your specific circumstances. Kilowatt-hours or gallons per 100 miles lets you make such calculations based on your driving needs and the prices where you live for electricity (which is billed to you in kWh) or gasoline.
