2023 Audi S4: What's New, Specs & Features
Last updated August 4, 2026
The main change for the 2023 Audi S4 is that the Premium Plus gains a Bang & Olufsen 3D sound system as standard, with Prestige receiving it as part of its inherited equipment. Otherwise, this is a lightly updated carryover with the same turbocharged V6, eight-speed automatic, standard AWD, styling, and overall structure.
About the 2023 Audi S4
Fifth A4-based generation, in its facelifted 2020-2025 phase; 2023 is a late-cycle year before 2024 added more standard driver-assistance equipment.
The S4 is Audi's understated sport sedan: a compact luxury four-door that pairs a strong V6 with standard quattro all-wheel drive and a sharper suspension than the regular A4. Its core appeal is real-world speed, secure all-weather traction, and a polished cabin that is easy to live with every day. Compared with louder rivals, the S4 leans more toward balanced daily performance and interior quality than toward aggressive styling or a track-first personality.
Every 2023 S4 uses a 349-horsepower turbocharged 3.0-liter V6, an eight-speed automatic, standard AWD, and a sport-tuned suspension. Premium covers the essentials with a 10.1-inch touchscreen and wireless Apple CarPlay and Android Auto, while Premium Plus emphasizes cabin technology and driver assistance. Prestige tops the range with navigation, a head-up display, heated rear seats, quieter front side glass, and automated parking assistance.
