In a landmark assessment of long-term EV durability, Germany’s ADAC has completed a rigorous four-year endurance test of the Volkswagen ID.3 — and the results are a major win for the electric mobility movement. After covering more than 160,000 kilometres under demanding conditions, the ID.3 Pro S retained an impressive 91% of its original battery capacity, far exceeding expectations.
Tested at the ADAC’s Test and Technology Centre in Landsberg am Lech, the ID.3 Pro S — equipped with a 77 kWh battery — was subjected to an aggressive usage profile designed to accelerate battery wear. Over 40% of its charging sessions used DC fast chargers, and the vehicle was often left fully charged for days at a time, both conditions known to stress lithium-ion cells. Despite this, the ID.3’s battery degradation remained minimal.
Martin Sander, Volkswagen Board Member for Sales, Marketing and After Sales, commented on the results: “A high battery capacity of over 90 per cent after 160,000 kilometres confirms that our ID. models are also very attractive as used cars and continue to meet the requirements of our customers.”
Notably, this was the first endurance test conducted by the ADAC on a member of Volkswagen’s all-electric ID. family. Between test drives, engineers frequently inspected the car’s battery health, chassis, and software performance — areas that could show early signs of wear in EVs subjected to extreme usage.
Volkswagen’s commitment to over-the-air updates also played a pivotal role in the ID.3’s performance. Throughout the test, the vehicle received several software upgrades, including the Electric Vehicle Route Planner. This intelligent feature calculates the most efficient charging stops on long routes, considering traffic and energy usage forecasts. Other updates improved power consumption, especially during short trips and colder weather conditions — a critical factor for European buyers facing winter range anxiety.
Beyond the battery, the ID.3’s mechanical integrity also stood strong. ADAC engineers reported that the chassis, axles, and steering remained in solid condition, with no major faults or weaknesses despite the high mileage.
For consumers still wary of the longevity of electric vehicles, the ID.3’s performance is a reassuring data point. Volkswagen backs the battery of every ID.3 with a guarantee of at least 70% capacity after eight years or 160,000 kilometres — a threshold the tested vehicle surpassed with ease.
ADAC’s recommendation is clear: keep your software up to date to enjoy the full potential of your EV. And if you’re in the market for a used electric car, the ID.3 might just be one of the most reliable choices out there.
