How Much Does the Range of Electric Cars Decrease on Highways?

[DeGrant]

Electric cars generally experience a 30% range reduction on highways. A 10% range reduction in urban areas during summer is normal: Under testing standards, most pure electric vehicles achieve over 86% of their official NEDC range in urban summer conditions. Some models, like the tested Buick Velite 6 and BYD e2, even exceed their official NEDC range in urban summer driving. Therefore, a 10% or smaller range reduction during urban summer use is indeed normal. A 30% range reduction in urban areas during winter is normal: Compared to urban summer range, winter urban range test results typically fall between 65% to 85% of the official NEDC range, with most around 70%. So a 30% range reduction for pure electric vehicles during urban winter driving is quite normal.
