About the Audi A6 Sportback e-tron
The Audi A6 Sportback e-tron is the sleeker, fastback saloon counterpart to the A6 Avant estate. Built on the same 800-volt PPE platform, it benefits from marginally better aerodynamics thanks to its lower roofline, which translates into slightly longer range figures — up to 463 miles WLTP in the most efficient rear-wheel-drive configuration.
Charging at up to 270 kW DC makes long journeys straightforward, with a 10–80% fill taking approximately 21 minutes. The platform offers both 75.8 kWh and 94.9 kWh battery options, with rear-drive or quattro all-wheel-drive layouts.
Inside, the cabin is pure modern Audi — a wide, curved display landscape with the latest MMI system, high-quality materials, and excellent noise insulation. The Sportback trades a little rear headroom and boot practicality versus the Avant for a more elegant silhouette, making it the choice for buyers who prioritise style alongside substance.
What the press thinks
The A6 Sportback e-tron draws praise for its outstanding range figures, ultra-fast charging, and refined interior. Reviewers note it is one of the most aerodynamically efficient EVs on sale. Minor criticisms include the numb steering feel and high entry price, but it is widely considered a benchmark executive EV saloon.
