The B7 RS4 represents the swan song of naturally aspirated Audi RS models, housing a glorious 4.2-liter V8 that screams to 8,250 rpm. This Neckarsulm-built sedan delivered 420 horsepower through a proper six-speed manual and Quattro all-wheel drive, making it the last of its kind before turbocharging took over. The B7's aggressive flared arches and carbon fiber accents hint at its motorsport DNA, while the interior features Recaro buckets and Alcantara trim. With only three model years of production and increasing scarcity of clean examples, the B7 RS4 has become highly sought after by enthusiasts who appreciate its analog character and naturally aspirated soundtrack—qualities that modern RS models simply can't replicate.
