About the 2003 Audi S4

The B6-generation S4 represents Audi's bold departure from turbocharging, introducing the legendary 4.2-liter V8 that would define the model for years. This naturally aspirated jewel produces 344 horsepower and delivers an intoxicating soundtrack that turbo models simply can't match. The Quattro all-wheel-drive system and six-speed manual transmission create a perfectly balanced sports sedan that's equally at home carving canyons or devouring autobahn miles. What makes these particularly compelling for collectors is their relative rarity, production was limited compared to later generations, and finding clean, unmodified examples grows increasingly difficult. The B6 S4's combination of analog driving experience, bulletproof V8 reliability, and understated Teutonic elegance has created a devoted following. Values have stabilized after years of depreciation, making well-maintained examples attractive propositions for enthusiasts seeking the last of the naturally aspirated S4s before Audi's return to forced induction.
