Audi S6 e-tron versions and prices

Guide prices checked October 2026 and may already include the Electric Car Grant. Real-world range is EV Database's typical estimate; the official WLTP figure is higher. Always confirm the price with the seller.

Charging

The Audi S6 e-tron Sportback can rapid charge at up to 269 kW. That peak only lasts part of a session: averaged from 10% to 80%, it is about 186 kW, about 23 minutes on a fast enough charger.

At home it accepts up to 11 kW on AC. On a typical 7 kW wallbox, a full charge from empty takes roughly 14 hours for the largest battery; most top-ups take far less. Its CCS plug is on the left side, rear. See charging times, smart EV tariffs and chargers near me.

Real-world range

For the Audi S6 e-tron Sportback, EV Database estimates these ranges. Cold means about −10°C with the heating on; mild means about 23°C; motorway means a steady 70 mph.

Heat pump: standard. One-stop motorway range with a 15-minute charge: about 412 miles. Try the range reality check or the range map for your own driving.

Running costs

At 10,000 miles a year, charging 80% at home on a smart tariff at 7.6p per kWh and 20% on rapid chargers at 79p, the Audi S6 e-tron Sportback would use about 3,056 kWh and cost about £669 a year to charge (6.7p a mile). Vehicle tax: £10 in the first year, then £200 a year, plus the £440-a-year expensive car supplement in years 2 to 6 because its list price is over £50,000. From April 2028 the pay-per-mile charge (eVED) is due to add 3p a mile, about £300 a year at 10,000 miles.
