How much range does an electric car lose in cold weather, AAA found 39% at 20 degrees Fahrenheit

How much range does an electric car lose in cold weather

How much range does an electric car lose in cold weather is the question anyone planning a winter drive needs answered first. AAA, the American Automobile Association, ran its own test on 3 electric vehicles using a chassis dynamometer, a machine that lets a car run in place while sensors measure exactly how much energy it draws, and drove them at 20, 75 and 95 degrees Fahrenheit with the cabin heater and air conditioner both set to 72 degrees. At 20 degrees, the cars lost 39% of the range they showed at 75 degrees. At 95 degrees, the same cars lost only 8.5%. Cold costs an electric car more than 4 times what heat does.

Charging in the cold costs more too

That lost range has to be replaced somewhere, and AAA priced it in its own release. Driving 1,000 miles at 20 degrees costs 28.44 dollars in a gas electric hybrid, 32.11 dollars in an electric vehicle charging at home, and 76.93 dollars in an electric vehicle charging at public stations. Subtracting the home charging figure from the public charging figure shows the public charging premium alone adds about 44.5 dollars to every 1,000 miles driven in that cold. At 95 degrees the same gap between home and public charging is only about 9.5 dollars, so most of the winter cost jump comes from where a driver charges, not the cold by itself.

Real world driving data shows a smaller but still real loss

Recurrent, a company that tracks more than 30,000 electric vehicles through their own onboard data instead of a lab, finds a smaller average loss than the AAA controlled test, but the same direction. Recurrent found electric vehicles retain 78% of their range at 32 degrees Fahrenheit, a 22% average loss, and names the heat pump, a device that moves heat from outside air into the cabin using 3 to 4 times less electricity than the resistive heaters older cars use, as the single biggest factor a buyer can check before choosing a car. An earlier Recurrent analysis found electric vehicles with no heat pump lost 28% of their range in the cold, against 13% for ones that had one, roughly halving the loss.

The anxiety around winter and reduced range, while it's not inaccurate, is just a bit overhyped.

Norway shows what a whole cold climate market looks like

Norway offers the clearest picture of a cold climate market, since electric vehicles are already the everyday car there. The Norwegian Automobile Federation put 26 electric vehicles through its 2026 winter range test in temperatures as low as negative 32 degrees Celsius and found an average loss of 38% against each stated range, worse than the 18% average loss the same organization measured in its own milder 2025 test. The best performers, the Hyundai Inster and the MG IM6, lost 29% of their stated range. The worst, the Lucid Air, lost 46%, though it still covered 519 kilometers of a stated 960 kilometer range.

Nobody who has actually driven an electric vehicle through a real winter describes it as a surprise. Ingrid Malmgren, senior policy director at Plug In America, drove one from Vermont to Quebec in 7 degree Fahrenheit weather.

But it was a complete non-issue. We charged once along the way.
