Ford released five-year durability data for 36,000 2021 Mustang Mach-E batteries, showing they retain 92% health after 100,000 miles. According to Ford From the Road and The EV Report, the data demonstrates that EV batteries are aging better than many expected, with minimal degradation over five years of real-world driving. Forbes notes this represents a strong report card for the 'Class Of 2021' Mustang Mach-E, while Axios frames the results as evidence that EV batteries are aging better than anticipated. InsideEVs emphasizes the scale of the test—36,000 batteries—providing statistically significant real-world validation. The results could influence consumer confidence in used EV markets and support Ford's electrification strategy, though questions remain about long-term performance beyond five years and how newer battery chemistries may differ.
