Ford tested 36,000 Mustang Mach-E vehicles: batteries retained 92% capacity
Ford collected data on the battery condition of 36,000 2021 model year Mustang Mach-E vehicles in the U.S. and Canada. On average, they retained 92% of their usable capacity.
Ford tested the batteries of 36,000 Mustang Mach-E electric crossovers sold in the U.S. and Canada. On average, the vehicles traveled 55,000 miles over 5.2 years and retained 92% of their original usable battery capacity.
Over 2,000 cars with mileage exceeding 100,000 miles retained more than 91% of their capacity. For more than 30 vehicles that traveled over 200,000 miles, the figure was 88%.
Results varied depending on operating conditions. Heat, frequent fast charging, and regular discharge to nearly zero accelerate battery wear. However, 95% of the vehicles showed results within the range of 87% to 97%.
All vehicles in the study were equipped with NCM batteries. Ford began installing LFP batteries in the Mustang Mach-E only starting with the 2023 model year.
The company recommends parking in the shade during hot weather, pre-cooling the cabin while the vehicle is connected to a charger, and using Level 2 charging for daily trips. Ford advises using Level 3 DC fast charging less frequently.
