The Audi S6 was built from 1994 to 2025.
The C7 S6, the most traded version: The C7-generation S6 represents Audi's sophisticated approach to the executive express formula, trading the previous V10's drama for twin-turbo V8 efficiency without sacrificing performance. The 4.0-liter TFSI produces 420 horsepower and 406 lb-ft, launching this Quattro-equipped sedan to 60 mph in just 4.4 seconds while delivering respectable fuel economy. What sets the S6 apart is its understated aggression—flared fenders, quad exhausts, and subtle S-badging hint at the performance beneath the refined exterior. The interior balances luxury with sport through diamond-quilted leather, carbon fiber trim, and Audi's excellent MMI system. As the last naturally-aspirated S6 successor before electrification takes hold, these models are gaining appreciation among collectors who value Audi's peak internal combustion engineering. Clean examples with maintenance records are becoming increasingly sought after, particularly in desirable colors like Sepang Blue or Phantom Black.
