Real-World EV Range Tests Find Discrepancies With EPA Estimates

The debate over range and ratings is being fueled by Edmunds’ test results


  • Edmunds has discovered that Tesla vehicles do not deliver indicated ranges.

  • A Tesla Model 3 Long Range still tops the chart.

  • The Porsche Taycan is the most underrated EV.


An electric vehicle’s range remains its strongest asset. Like muscle cars during the horsepower wars (still ongoing), an electric vehicle is only as worthy as its EPA-estimated range. The Environmental Protection Agency has long held the “truth” on efficiency however growing discrepancies between their range numbers and the real world have invited challengers to their methods and data. The latest and perhaps most credible is Edmunds.

In brief, Edmunds has found that their real-world outdoor tests poke numerous holes in the EPA’s range numbers. According to Edmunds, the EPA’s indoor dynamometer-based tests deliver results that can be far from reality.

Perhaps most “shocking” is that every Tesla they’ve evaluated has failed to meet their EPA-estimated ranges. Even so, a Model 3 Long Range still earned the crown for the longest range but even so, some Tesla vehicles fell 10% short. The big winner, and one that’s been a topic of debate since its introduction, is the Porsche Taycan. Nearly all who’ve driven a Taycan, including ourselves, have found that the estimated range numbers fell dramatically short of the car’s potential. In fact, Edmunds managed nearly 60% more distance than the EPA’s posted range.

Other “winners” following Edmunds test loops include the Ford Mustang Mach-E, Mini Cooper SE, the all-new Volkswagen ID.4, and the near entirety of the Hyundai Groups family of EVs.

If you’re curious or shopping for an EV, Edmunds’ work is worth a look.
