ADAC tests ID.3 for 99K miles, battery still holds 91% capacity

After undergoing a rigorous 99,000-mile (160,000 km) endurance test by ADAC over four years, Volkswagen’s ID.3 Pro S electric hatchback demonstrated exceptional battery durability and overall reliability. The vehicle’s 77 kWh battery retained 91% of its original capacity, significantly surpassing VW’s 70% warranty threshold. ADAC subjected the ID.3 to harsh real-world conditions including frequent fast charging (over 40% of sessions), leaving the battery fully charged for extended periods, freezing temperatures, and long highway drives. Despite this aggressive usage, the battery showed minimal degradation, instilling confidence in the long-term viability of VW’s electric platform. The test also highlighted the benefits of a major software update that increased DC fast-charging speeds from around 125 kW to over 160 kW, improved range and efficiency—especially in cold weather—and introduced smarter route planning and battery management. Impressively, the ID.3 completed nearly 400 km in subzero
