Porsche Taycan EV's EPA Range Goes from Bad to Worse

  • The EPA's range estimate for the Porsche Taycan Turbo S electric car is a low 192 miles.
  • That's 9 fewer miles than its slightly less powerful stablemate, the Taycan Turbo.
  • Like it did with the Taycan Turbo, Porsche has commissioned its own "real-world" range test, which shows a result of 278 miles for the Taycan Turbo S.

The new Porsche Taycan EV continues to disappoint in terms of efficiency ratings, as the EPA has now released numbers for the top-dog Taycan Turbo S. As expected, the Turbo S—which has a more powerful rear electric motor—is even less efficient than the Turbo, posting a result of 68 MPGe combined and a range of 192 miles in the EPA's testing.

Porsche told C/D that it agrees with the EPA's result given that the 750-hp Turbo S also has a higher drag coefficient and larger tires than the 670-hp Turbo. But just because Porsche accepts the number doesn't mean it likes the number. As it did with the Taycan Turbo, Porsche hired a third-party testing agency, AMCI, to run a separate range test. And that supposed "real-world" result for the Turbo S was wildly different than the EPA's: 278 miles.

Curiously, that's even better than the AMCI's 275-mile combined result for the Turbo, but Porsche explained that the disparity comes down to tires. The Turbo that AMCI tested was wearing more aggressive Michelin Pilot Sport4 summer tires, while the Turbo S that the agency ran was wearing Continental ProContact all-season rubber.

We look forward to testing the Taycan ourselves in our 75-mph highway range test. A 2018 Tesla Model S 100D that we ran through this highway test achieved 270 miles, against an EPA combined rating of 335 miles. Since then, the Tesla Model S has improved its EPA-rated combined range, with the 2020 Model S Long Range hitting a whopping 373 miles—yes, nearly double the Taycan Turbo S's range.
