The Audi S4 B9 has been built since 2017.
The S4, the most traded version: The B9-generation S4 represents Audi's refined approach to the sport sedan formula, trading the beloved supercharged V6 for a more efficient 3.0-liter turbocharged unit producing 354 horsepower. While purists mourned the loss of the supercharger's instant throttle response, the new engine delivers broader torque and improved fuel economy without sacrificing the S4's signature all-weather capability. Quattro all-wheel drive remains standard, paired with an eight-speed tiptronic that's more responsive than its predecessor. The interior showcases Audi's latest MMI infotainment and Virtual Cockpit technology, while the exterior receives subtle but purposeful styling updates. Though not as immediately collectible as earlier S4 variants, clean examples with manual transmissions (where available) and desirable options like the sport differential will likely appreciate as the last naturally-aspirated S-cars become increasingly sought after. The sweet spot for collectors remains low-mileage, well-documented examples from the early production years.
