A new study by AAA provides some firm data to back up what most electric vehicle owners know, and few electric vehicle manufacturers mention in their advertisements. EV range is dramatically reduced in cold temperatures. How much is it reduced? On average about 41% according to AAA who compared the driving range of five battery-electric vehicles (BEVs) at 20F to the driving range at 75F.
The study includes affordable, premium, and luxury BEVs. Among the vehicles studied, the BMW i3 had the most reduction as a percentage of its range and the Nissan Leaf, the least reduction. The Tesla Model S, eGolf, and Bolt were in the middle area of range reduction. Every EV studied had a significant reduction.
