About the 2006 Audi S4

The B7-generation S4 represents Audi's last naturally aspirated V8 S4, making it increasingly coveted among enthusiasts who prize linear power delivery over turbo lag. Its 4.2-liter V8 produces 344 horsepower and that intoxicating high-rpm wail that disappeared when Audi switched to supercharged V6s. Built on the same platform as the RS4, it shares much of the suspension DNA while offering more daily usability. The Avant wagon variant is particularly sought-after, combining 155mph capability with genuine practicality. These cars have aged gracefully, with their understated flared fenders and subtle aggression looking more purposeful than flashy modern performance sedans. Carbon build-up on intake valves remains the primary concern, but well-maintained examples are appreciating as collectors recognize this as the end of an era for Audi's naturally aspirated performance cars.
