Last updated August 4, 2026

About the 2025 Audi S8
4th-generation A8/S8 (2019-2026 U.S. run), after the 2022 update; 2025 is a late-cycle year.
Audi positions the S8 as the performance version of its flagship luxury sedan rather than a flashy muscle car. It is aimed at shoppers who want full-size rear-seat space, a quiet high-end cabin, and understated styling, but also want a serious V8 and sharper handling than a typical large luxury sedan. Compared with rivals, the S8 leans on discreet design, standard AWD, and sophisticated chassis tech instead of shouting for attention.
The sole S8 version remains Audi’s understated flagship sport sedan, combining a long-wheelbase luxury cabin with a 563-hp twin-turbo V8 and standard AWD. Its performance hardware includes rear-wheel steering and a sport rear differential, while 22-way front seats provide heating, ventilation, and massage. Dual touchscreens, wireless Apple CarPlay and Android Auto, navigation, and Bang & Olufsen audio cover the main cabin technology.
