In a significant challenge to Tesla's long-standing reputation for battery longevity, new findings from what is being called the largest EV battery health study to date show that Hyundai vehicles are outperforming their rival in real-world battery degradation. The research, which analyzed data from thousands of electric vehicles, measured how much capacity each brand's batteries lost over time — a key metric that directly impacts range, resale value, and long-term ownership costs. The results suggest that Hyundai's battery management systems and cell chemistry choices may be giving its EVs an edge in durability, a finding that could shift consumer perceptions as the electric vehicle market becomes increasingly competitive. For buyers weighing their options, the data adds another important data point beyond range and charging speed when evaluating which EV will hold up best over years of daily driving.
