Q4 e-tron battery degradation and used range
EV batteries lose capacity slowly. At the average rate measured across 22,700 EVs (2.3% a year), a 2022 Q4 e-tron rated for 388 km would have roughly 354 km of range today.
Q4 e-tron used range by model year
| Model year | Rated when new | Age (years) | At 1.5%/yr | At 2.3%/yr | At 3.0%/yr |
|---|---|---|---|---|---|
| 2022 | 388 km | 4 | 365 km | 354 km | 343 km |
| 2023 | 389 km | 3 | 372 km | 363 km | 355 km |
| 2024 | 463 km | 2 | 449 km | 442 km | 436 km |
| 2025 | 463 km | 1 | 456 km | 452 km | 449 km |
| 2026 | 463 km | 0 | 463 km | 463 km | 463 km |
The three columns reflect how the car was charged. Telematics firm Geotab found about 1.5% a year for EVs that rarely use DC fast chargers, 2.3% on average, and around 3% for EVs that fast-charge heavily at high power. Rated range is the longest version for each model year.
Checking a used Q4 e-tron
Ask the seller for a battery health or state-of-health report from a dealer or a battery-testing service, and check whether the original battery warranty still applies. A full charge that shows a much lower range estimate than this table, in mild weather, is worth questioning.
