EVs Fall Short of EPA Estimates by a Much Larger Margin Than Gas Cars in Our Real-World Highway Testing
Story by Caleb Miller • Yesterday 8:01 PM

SAE International has just published a paper co-authored by Car and Driver's testing director, Dave VanderWerp, showing that, in our testing, EVs are far worse at matching EPA estimates than gas-powered vehicles.

The paper compares EPA fuel-economy and range estimates to the results of C/D's real-world highway tests, with EVs failing to meet the EPA's range figures on average.
 
The authors propose solutions like more standardized testing procedures and the inclusion of both city and highway range figures on new vehicles' Monroney price stickers.

A new paper published by SAE International uses Car and Driver's real-world highway test data to show that electric vehicles underperform on real-world efficiency and range relative to the EPA figures by a much greater margin than internal-combustion vehicles. While the latter typically meet or exceed the EPA-estimated highway fuel economy numbers, EVs tend to fall considerably short of the range number on the window sticker. The paper, written by Car and Driver's testing director, Dave VanderWerp, and Gregory Pannone, was presented this week at SAE International's annual WCX conference. It points to a need for revised testing and labeling standards for EVs moving forward.

The unity of government which constitutes you one people is also now dear to you. It is justly so, for it is a main pillar in the edifice of your real independence, the support of your tranquility at home, your peace abroad; of your safety; of your prosperity; of that very liberty which you so highly prize. But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth.  George Washington - Farewell Address

  • I was a "conspiracy theorist". Now I'm just right.
How about some real-world tests? Somewhere other than the sunbelt?

Drive from Rapid City SD to Casper WY on a cold winter day (-20, windy) or from Dickinson ND to Fargo.

Call when you run out of juice.

Flat terrain, warm weather, low wind estimates are just not real world indicators of range, at least not in the Northern Plains. MY problem with this sticker mileage nonsense is that if someone naively buys a vehicle thinking the range for a charge is correct for their driving conditions here, they will likely experience far less range, and that could be deadly in areas where population densities are low and towns far apart.

Yes, Virginia, it is a matter of life and death.

Seventeen Techniques for Truth Suppression

Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.
