A new study by Consumer Reports reveals that the driving range of electric vehicles including Teslas can be cut in half during winter months in cold climates.

A study published by Consumer Reports has revealed that the driving range of Tesla’s cars and electric vehicles is seriously diminished by cold climates; something which many owners discovered recently during the polar vortex which hit parts of the United States. The report used two different brands of electric vehicles, one Tesla Model 3 and one Nissan Leaf, to compare how they both reacted to extremely cold weather.

Jake Fisher, the senior director of auto testing at Consumer Reports, commented on the company’s findings stating: “Typically, we warn new-car shoppers not to buy more vehicle than they need, whether that’s seats, cargo room, or towing capacity. But in this case, EV buyers who drive in colder climates should strongly consider getting a car with a range about double what their daily driving needs are, so they’re not left stranded in a cold snap.”
