Tesla Model 3, Model Y Lose About 9 Percent Range at Near-100,000 Miles: InsideEVs Analysis
InsideEVs examined battery health data from high-mileage examples of both models and found degradation varies by variant.
Real-world battery degradation data from Tesla Model 3 and Model Y owners with nearly 100,000 miles on the clock shows approximately 9 percent range loss for some variants.
What Happened
InsideEVs gathered battery health data from high-mileage examples of both the Model 3 sedan and Model Y crossover. The analysis compared each vehicle's current maximum charging capacity against its original EPA-rated range to calculate real-world degradation. Researchers examined standard-range and long-range variants of each model, finding that degradation at near-100,000 miles reached approximately 9 percent for some configurations while remaining lower for others.
Why It Matters
Battery longevity directly affects total cost of ownership, resale value, and whether long-distance travel remains viable as the vehicles age. For buyers weighing new versus used EVs, understanding actual degradation at high mileage helps determine if Tesla's durability claims hold up in practice rather than relying on manufacturer projections alone. The range loss documented by InsideEVs suggests that even high-mileage examples retain roughly 90 percent or more of their original EPA-rated driving range.
The Bottom Line
The InsideEVs findings offer concrete real-world data showing battery degradation at near-100,000 miles results in approximately 9 percent range loss for certain Model 3 and Model Y variants, giving prospective buyers and owners a clearer picture of what to expect from long-term range retention.
