Hoping to increase the appeal of their battery-electric vehicles, automakers have begun rolling out an assortment of "long-range" models, such as the Tesla Model 3, Chevrolet Bolt EV, Jaguar I-Pace and Nissan Leaf Plus.
Under ideal conditions, these products can deliver more than 200 miles per charge and, in some cases, even 300. But as many owners discovered last week as winter storms slammed much of the country, cold weather does not qualify as "ideal." A new AAA study finds that when the thermometer dropped to 20 degrees Fahrenheit, range fell by an average of 41 percent on the five models it tested.
"We found that the impact of temperature on EVs is significantly more than we expected," said Greg Brannon, AAA's director of automotive engineering.
Some EV drivers — including this correspondent — recently found that range can drop by half when the mercury tumbles into negative territory. The AAA study appears to be the first to have used standard, repeatable methodology to confirm the problem and compare the effect of winter temperatures on different models.
