Cold Weather Impacts Ford Mustang Mach-E Range, Study Finds

A new study conducted by the Canadian Automobile Association (CAA) has confirmed what previous research has indicated: electric vehicles, including the Ford Mustang Mach-E, experience a reduction in range during cold winter conditions. The CAA's testing, which involved 14 different EVs, subjected vehicles to temperatures between -7 and -15 degrees Celsius, typical of Canadian winters. Each vehicle was driven until the battery was fully depleted, and the results were compared against official range estimates published by Natural Resources Canada (NRCan).

The Ford Mustang Mach-E achieved 334 kilometers (208 miles) on a single charge in the CAA test. This result represents a 31 percent decrease compared to its official NRCan rating of 483 kilometers (300 miles). While a significant reduction, the Mach-E's performance placed it squarely in the middle of the pack, ranking seventh out of the 14 EVs tested. This suggests that while the Mach-E is affected by cold weather range loss, its performance is comparable to other EVs in similar conditions.

Beyond range, the CAA study also assessed charging speeds. The Mach-E added 71 kilometers of range in a 15-minute DC fast-charging session and took 46 minutes to charge from 10 to 80 percent, achieving an average charging speed of 85 kW. This performance placed the Mach-E ninth in charging speed among the tested vehicles. These charging results, combined with the range test, provide a comprehensive picture of the Mach-E's performance in cold weather.

Ford has acknowledged the cold weather range challenges faced by EVs and has taken steps to mitigate these effects. The 2025 model year updates for the Mach-E include a standard heat pump, a feature designed to improve efficiency in colder temperatures. While this addition is expected to positively impact range, it does come at the cost of slightly reduced frunk space. The CAA study provides valuable real-world data on EV performance in winter conditions and highlights the ongoing efforts by manufacturers like Ford to address these challenges.
