LANSING, Mich. (Michigan News Source) – A new study from the AAA Automotive Engineering research team found that electric vehicles (EVs) lost significant range when heavily loaded.

The study tested the Ford F-150 Lightning loaded with 1,400 pounds of sandbags, equivalent to about 70 bags of mulch or 20 bags of concrete mix. When heavily loaded, the truck’s range dropped by nearly 25%, from 278 miles to 210.

“Our testing revealed a significant range reduction, but it’s important to note that the Lightning was loaded to near its maximum capacity,” said Greg Brannon, director of AAA Automotive Engineering. “Most buyers will likely use their Lightning with a lighter load, resulting in a much smaller range reduction.”

The study also found that the unloaded vehicle was about 6% less efficient than estimated by the EPA predicted, with an approximately 7% shorter range.

“This study is important for broadening our understanding of the limitations of electric vehicles,” said Adrienne Woodland, spokesperson for AAA — The Auto Club Group. “Range anxiety remains a top reason consumers are hesitant to switch from gasoline-powered vehicles to EVs. While this study may heighten concerns, it’s worth remembering that excess weight reduces fuel economy in gas-powered vehicles too.”
