2025 Audi A6 e-tron electric car detailed: Up to 750km of range from new premium EV player

Goodbye to the petrol- and diesel-powered Audi A6 range because the new-generation version is now a battery electric vehicle (BEV), boasting a driving range claim of up to 750km on a single charge.

But there are more changes than just powertrain, with the sedan body style now discontinued making the 2025 Audi A6 e-tron a Sportback (liftback) or Avant (wagon) proposition.

Though Australian details are yet to be confirmed, the A6 e-tron will land in local showrooms in the first half of next year, like the mechanically related Q6 e-tron SUV, as the next model in Audi’s new naming nomenclature that sees every even-numbered vehicle becoming an electric car.

Four variants have so far been revealed, mirroring the Q6 e-tron, kicking off with the base A6 e-tron that has a 210kW single-motor, rear-wheel-drive set-up and an 83kWh battery for a circa-610km claimed driving range for the Sportback.

Moving up to the A6 e-tron performance, power figures are boosted to 270kW, while the battery size also expands to 100kWh for a claimed 750km range.

This cruising distance exceeds stated ranges of the A6 e-tron-rivalling BMW i5 (up to 582km) and Mercedes-Benz EQE (up to 626km).

Taking another step up the A6 e-tron ladder, the quattro then adds an electric motor to the front axle for all-wheel drive and a 315kW combined output, while claimed range is pegged at 700km.

Finally, the flagship variant for now is the S6 e-tron with an up-to-405kW output (with launch control, otherwise power sits at 370kW) and a claimed 670km driving range.

Opting for the Avant body style in any variant will cut driving range by 30km, according to Audi.

Audi has also hinted a full-fat RS6 e-tron is on the horizon, but won't be ready for some time yet.

In terms of performance, the S6 e-tron is the quickest to accelerate from zero to 100km/h, claimed to need just 3.9 seconds to reach the landmark speed, followed by the A6 e-tron quattro (4.5s), A6 e-tron performance (5.4s), and then the A6 e-tron (6.0s).

As the second Audi model built on the new Premium Platform Electric (PPE) architecture, the A6 e-tron also has 800-volt capabilities, allowing it to recharge at a maximum rate of 270kW.

As such, the A6 e-tron’s battery can recharge from 10 to 80 per cent capacity in as little as 21 minutes or add around 300km from 10-minute charge.

With aerodynamically optimised body work, one of the headline statistics for the new A6 e-tron is its low drag coefficient (Cd) of 0.21 for the Sportback and 0.24 for the Avant, which partially explain's the wagon's reduced driving range.

This makes both models slipperier than a McLaren Speedtail (0.278 Cd), while the Sportback bests even the Tesla Model 3 (0.23 Cd) and Porsche Taycan (0.22 Cd).

Exterior styling highlights on the 2025 Audi A6 e-tron include full OLED lighting front and rear, as well as a minimalist design that eschews panel creases in favour of flat surfaces.

Up front, the new EV sports Audi’s signature single-frame front grille, but it is enclosed to denote its all-electric powertrain.

However, the bumper still features intakes to promote cool air flow to the battery.

Like most Audi models, the A6 e-tron also features subtly blistered wheelarches as a nod to the brand’s quattro all-wheel-drive heritage, while the door handles are recessed into the body work.

At the rear, the Sportback and Avant body styles are obviously differentiated rooflines and cargo openings, but both feature body-width-spanning tail-lights and a prominent diffuser for better aerodynamics.

S6 e-tron grades are further distinguished by larger alloy wheels (now measuring 20 inches compared to the standard car’s 19s), as well as contrasting silver accents on the front and rear bumpers, and window surrounds.

Audi is touting eight exterior colour options, but exactly what will be made available to Australians is still unclear.

Overall, the A6 e-tron Sportback measures 4928mm long, 1923mm wide, 1487mm tall, and features a 2946mm wheelbase, roughly making it the same size as the outgoing A6 sedan.

The Sportback features a 502-litre boot, which can expand to 1330L with the rear seats folded, as well as a 27L front boot area.

As for the A6 e-tron Avant, its length, width, and wheelbase match the Sportback, but its 40mm taller at 1527mm.

Despite the bigger rear end, the Avant can accommodate the same 502L volume in the boot as the Sportback, which suggests this measured to seat backrest height. The Avant is rated with an additional 92L of space (totalling 1422L) with the rear seats folded down, which suggests this latter measurement is all the way to the roof.

The local equipment list is still to be confirmed, but highlights of international specification include Audi’s next-generation virtual exterior mirrors, a panoramic glass roof, and an illuminated rear logo.

Inside, some overseas versions sport a leather-free interior to boost Audi’s sustainability credentials, while an 11.9-inch Virtual Cockpit, 10.9-inch passenger display, and 14.5-inch infotainment touchscreen also feature.

The latter is powered by Android Automotive software, and features in-built satellite navigation, digital radio, and touchscreen games to keep occupants entertained while charging.

Aside from specification, pricing is another piece of the A6 e-tron puzzle.

In European markets, the A6 e-tron Sportback will start at around €85,000 ($AU140,200) and the S6 e-tron Sportback will sit just under €100,000 ($AU164,940), with the Avant body style incurring a €6500 ($AU10,720) premium.

Full Australian details are expected to be revealed closer to the A6 e-tron’s 2025 local launch.
