How long to charge a Audi A6 e-tron at home
Typical trim (A6 e-tron): 30.3 kWh/100 mi · EPA range 348 mi · on a 48 A (11.5 kW) charger about 38 mi of range per hour*
EPA lists a 240 V full-charge time of 12 h for this trim, which implies an average of roughly 8.8 kW (our estimate, = 105 kWh ÷ 12 h). Chargers well above that are unlikely to charge this car faster on AC; check the owner's manual for the onboard charger rating.
Range added by charger size (typical trim)
| Charger | Range per hour | Per 8-hour night | Empty to full EPA range |
|---|---|---|---|
| 12 A at 120 V (Level 1 cord) (1.4 kW) | 5 mi | 38 mi | 73.2 h |
| 16 A at 240 V (3.8 kW) | 13 mi | 101 mi | 27.5 h |
| 24 A at 240 V (5.8 kW) | 19 mi | 152 mi | 18.3 h |
| 32 A at 240 V (7.7 kW) | 25 mi | 203 mi | 13.7 h |
| 40 A at 240 V (9.6 kW) | 32 mi | 253 mi | 11.0 h |
| 48 A at 240 V (11.5 kW) | 38 mi | 304 mi | 9.2 h |
| 64 A at 240 V (15.4 kW) | 51 mi | 406 mi | 6.9 h |
| 80 A at 240 V (19.2 kW) | 63 mi | 507 mi | 5.5 h |
*Estimates: charger kW ÷ EPA kWh/100 mi × 100, assuming the car accepts that power. Charging tapers near 100% and is slower in the cold.

| Trim | kWh/100 mi | EPA range | EPA 240 V charge time | Energy for full range (est.) | Source |
|---|---|---|---|---|---|

Source: fueleconomy.gov vehicle records (2027 model years). "Energy for full range" = kWh/100 mi × range ÷ 100, measured at the wall, so it includes charging losses and is not the battery size. Usable battery capacity is not in EPA data (data gap).
Will a bigger charger charge it faster? (per trim)
Times are empty to full EPA range. They are capped at the onboard charger rating only where EPA's own trim name states it. Otherwise they assume the car accepts the charger's full power, which may overstate the gain from 48 A and 80 A units.
| Trim | 32 A | 40 A | 48 A | 80 A | EPA 240 V time | What EPA data shows |
|---|---|---|---|---|---|---|
| 2027 A6 e-tron ultra | 13.6 h | 10.9 h† | 9.1 h† | 5.5 h† | 12 h | EPA time implies 8.7 kW average; EPA data alone can't say whether it accepts more. Check the manual. |
| 2027 A6 e-tron quattro ultra | 13.5 h | 10.8 h† | 9.0 h† | 5.4 h† | 12 h | EPA time implies 8.6 kW average; EPA data alone can't say whether it accepts more. Check the manual. |

† Only if the car accepts that much power. This charger is more than 10% above the average power implied by EPA's own 240 V time, so treat EPA's time as the realistic figure.
