After 87,000 Miles, This 2022 Tesla Model Y Didn't Just Lose Range. It Charges Slower Too
ADAC testing reveals battery degradation impacts more than EPA-rated range on a high-mileage Model Y.
A 2022 Tesla Model Y tested by ADAC after covering approximately 87,000 miles showed measurable battery degradation affecting both driving range and charging speed.
What Happened
ADAC, Germany's largest automobile club, conducted real-world testing on a 2022 Tesla Model Y that had accumulated around 87,000 miles. The test revealed that the vehicle's battery capacity had declined noticeably compared to factory specifications. Beyond expected range reduction from degradation, the SUV also demonstrated slower DC fast-charging speeds than when new—meaning longer stops at Superchargers for owners covering high annual mileage.
Why It Matters
For current and prospective Tesla owners, this report underscores a practical reality of lithium-ion battery chemistry: capacity fade is gradual but measurable over time. Buyers considering used Model Y vehicles should factor in battery age and usage history alongside price. Fleet operators and high-mileage drivers may also need to adjust route planning expectations as batteries age beyond typical warranty periods.
The Bottom Line
ADAC's long-term Model Y findings show that while Tesla's battery technology remains competitive, degradation affects both range and charging performance at higher mileage—information worth considering for anyone evaluating a used EV purchase or managing an aging fleet.
