Car and Driver drops the hammer on EV testing… Companies are lying…

  • 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.

“Basically we’ve taken a look at how vehicles perform relative to the values on the window sticker, looking at the difference between what the label says and what we actually see in our real-world highway test,” explained VanderWerp. “We see a big difference in that gap between gas-powered vehicles and the performance of EVs. The real question is: When first-time customers are buying EVs, are they going to be pleasantly surprised or disappointed by the range?”
