S6 Avant e-tron (MY25)

The Audi S6 Avant e-tron (MY25) is a 5-seat estate with all-wheel drive, on sale in the UK from £99,340. It accelerates from 0 to 62 mph in 3.9 seconds, quicker than 85% of the electric cars on sale in the UK. Its estimated real-world range is 329 miles (530 km) in a mix of town, country and motorway driving. That is longer than 89% of the 471 electric cars on sale in the UK, and 6th of 26 estates.

It uses around 3.5 mi/kWh (179 Wh/km), about the same as the typical EV on sale (3.5 mi/kWh). The usable battery holds 94.9 kWh and on a rapid charger it averages 186 kW between 10% and 80%. With one 15-minute charging stop, it can cover an estimated 390 miles (628 km) at motorway speeds.

It has a heat pump, which helps preserve range in cold weather, and it does not support vehicle-to-load (V2L). The battery uses NCM chemistry, which stores more energy for its weight than LFP.

Its UK starting price works out at £302 per mile of real-world range, higher than the median for estates (£256 per mile).

Second-hand, a 2024 example is estimated at £47,200–£53,100 and a 2025 one at £56,600–£64,600, based on typical EV depreciation. After typical battery wear, a 2024 car should still manage about 316 miles of real-world range. These are estimates, not valuations: check real prices before you buy.
