The Audi A6 Avant e-tron costs £32,705 more than the Mazda 6e. For that premium it adds 89 miles more WLTP range, 75 kW faster peak rapid charging and 166 litres more boot space. On EVcarsguide's combined category scores, the Audi A6 Avant e-tron comes out ahead overall.

The Mazda 6e is £32,705 cheaper to buy. Running costs are almost identical - about £152 a year either way, at 8,000 miles on an off-peak home tariff.

These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.

EVcarsguide estimates a real-world motorway range of about 364 miles for the Audi A6 Avant e-tron and 290 miles for the Mazda 6e - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi A6 Avant e-tron goes roughly 74 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 21-24 minutes.

The two are within 3 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 513 mm of total clearance for the Audi A6 Avant e-tron and about 510 mm of total clearance for the Mazda 6e. The Mazda 6e also turns in a 0.7 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi A6 Avant e-tron and 90% for the Mazda 6e. That gives the Mazda 6e a modest edge in retained real-world range. The Mazda 6e's LFP-type pack tolerates daily 100% charging, while the Audi A6 Avant e-tron's NMC-type pack lasts longest kept to about 80% for everyday use.
