A new study by Recurrent [company specializing in used electric vehicle data] has found that Tesla Model 3 and Model Y vehicles see a significant decrease in real-world driving range after just three years. The study, which analyzed data from over 12,000 Teslas, suggests that these cars are only achieving around 64% of their original EPA-rated range by that point.
It’s important to note that even new Teslas may not quite meet the EPA range estimates. The study found that even at zero miles, these models typically achieve only 70% to 72.5% of the advertised range. This highlights limitations in the EPA testing protocol, which doesn’t account for factors like temperature variations or highway driving speeds.
However, the key takeaway is the decline in range over time. Recurrent’s data suggests a 6% to 8.5% decrease in range after three years, which then levels off.
The study also points out that Teslas appear less affected by DC fast charging compared to some other EV brands. This could be a benefit for owners who frequently take road trips or lack access to slower home charging options.
Tesla responded to the study with data from their own research, which plots battery retention based on vehicle mileage rather than calendar age. This makes a direct comparison difficult. However, Tesla’s data suggests an average battery retention of over 80% after 150,000 miles.

InsideEVs has requested that Tesla provide data comparable to Recurrent’s study for a more accurate comparison. This story will be updated if that information becomes available.
