About the 2020 Audi S6

The C8-generation S6 represents Audi's bold pivot from naturally aspirated V8s to forced induction, housing a twin-turbo 2.9-liter V6 that delivers 444 horsepower and 443 lb-ft of torque. This TFSI engine, shared with the RS4 and Porsche Macan Turbo, propels the S6 from 0-60 in just 4.4 seconds while maintaining the refined daily usability that defines the S6 lineage. The 48-volt mild-hybrid system adds efficiency without compromising the visceral experience. Quattro all-wheel drive and adaptive air suspension ensure the S6 remains composed whether carving canyons or cruising autobahns. While purists mourn the loss of the naturally aspirated V8, this generation's advanced technology and impressive performance figures make it a compelling modern interpretation of the high-performance executive sedan formula. Clean examples with desirable options are becoming increasingly sought-after as enthusiasts recognize the C8's technological sophistication.
