The Audi S6 Sportback e-tron combines dual-motor all-wheel drive with a 100 kWh battery, a 3.7-second sprint to 60 mph, and a hatchback tailgate that can swallow more gear than any German competitor with a conventional trunk. After sitting out the 2026 model year in the US line-up, the car returns for 2027 with a cleaner trim structure and a reworked infotainment interface.
