Audi S6 e-tron Charging Time
A 2027 Audi S6 e-tron takes about 12 hours to charge from empty to full on a 240-volt Level 2 charger, according to its EPA test. On a standard 120-volt outlet it takes about 73 hours. A full charge puts about 105.1 kWh through the plug for 311 miles of range.
Audi S6 e-tron charging time by charger
Figures for the 2027 S6 e-tron (21 inch wheels). 20% to 80% is a typical daily top-up; 0% to 100% is a full charge from empty.
| Charger | Power | 20% to 80% | 0% to 100% |
|---|---|---|---|
| Level 1, 120 V outlet (12 A) | 1.4 kW | 43 hr 48 min | 3 days |
| Level 2, 240 V, 16 A | 3.8 kW | 16 hr 25 min | 27 hr 22 min |
| Level 2, 240 V, 24 A | 5.8 kW | 10 hr 57 min | 18 hr 15 min |
| Level 2, 240 V, 32 A | 7.7 kW | 8 hr 13 min | 13 hr 41 min |
| Level 2, 240 V, 40 A | 9.6 kW | 6 hr 34 min* | 10 hr 57 min* |
| Level 2, 240 V, 48 A | 11.5 kW | 5 hr 28 min* | 9 hr 7 min* |
* Only if the car's onboard charger accepts that much power. On its EPA test it charged at about 8.8 kW; if that is its limit, a faster wall charger won't shorten the 12-hour full charge.

Cost to charge a Audi S6 e-tron
A full charge from empty draws about 105.1 kWh from the wall. At 18 cents per kWh it costs about $18.92, and a 20% to 80% top-up about $11.35. The EPA rates the S6 e-tron (21 inch wheels) at 33.8 kWh per 100 miles, which works out to 6.1 cents a mile. The US average home rate was 18.16 cents per kWh in August 2026 (EIA); the EV charging cost calculator takes your own rate.
Audi S6 e-tron fast charging
DC fast charging bypasses the car's onboard charger and is far quicker, but the speed depends on each model's charging curve, which slows as the battery fills. That's why fast-charge times are quoted from 10% to 80%. The EPA doesn't test DC charging, so check Audi's quoted figure for the S6 e-tron. The EV charging curve guide explains why it slows.
