"The test started at 5% state of charge, and the trip computer was reset when the indicated battery percentage reached 0% to find out exactly how far the EV would go below that threshold. And finally, the Model 3 was driven with Tesla's Full Self-Driving (FSD) advanced driver assistance system activated, to see how it handles low-battery conditions such as this."
"When the Model 3's screen showed a 0% state of charge, it still displayed 2 miles of range remaining. But here's the unexpected part: Once the displayed remaining range was 0 miles, the Model 3 continued driving for another 31 miles. After hitting 0%, the Model 3 consumed nearly 6 kilowatt-hours of electricity, proving that Tesla leaves a big buffer for emergencies."
Electric vehicles retain reserve energy after the displayed state of charge reaches 0%. A 2026 Tesla Model 3 Premium was preconditioned and driven on a closed circuit from 5% SOC to depletion with the trip computer reset at 0% to measure underrun distance. The car was run with Full Self-Driving engaged to observe low-battery behavior. When the screen showed 0% SOC it still displayed two miles remaining; after the displayed range hit 0 miles the vehicle continued another 31 miles, consuming nearly 6 kWh. The Model 3 Premium has 363 EPA miles and averaged 192.5 Wh/mi (~5 miles/kWh). FSD eventually requested driver takeover and the car stopped with warnings.
