2025 Audi S4: What's New, Specs & Features
Last updated August 4, 2026
The 2025 Audi S4 is a light-update year, not a redesign. Its most important change is that Premium Plus gains standard navigation.
About the 2025 Audi S4
5th-generation A4/S4 family (B9/B9.5), facelift-era final U.S. model year before Audi shifts this role to the S5.
Audi positions the S4 as a compact luxury sport sedan that blends serious speed with everyday comfort. Its core appeal is the mix of a strong turbo V6, standard quattro all-wheel drive, and an upscale cabin that feels more understated than some rivals. For most shoppers, the S4 is the choice for quick acceleration, all-weather traction, and long-drive comfort without moving into a larger or flashier performance sedan.
The S4 remains a three-trim sport sedan, with every version pairing a 349-hp turbo V6 with an eight-speed automatic and standard all-wheel drive. Premium has massaging sport seats and wireless Apple CarPlay, Premium Plus features a 12.3-inch digital instrument display and premium audio, and Prestige brings a head-up display and upgraded headlights.
