It will keep up with the rivals such as the BMW M550i and the Mercedes-AMG E53 on a twisty road and also looks quite handsome pulling up to the valet stand on date night.
Inside, the S6 offers the same space and features as the A6, so passengers will find plenty of space and amenities to make them comfy on long trips. Not slick looking enough for you?
Audi also offers the mechanically similar S7, which features a racier fastback roofline—and the bonkers RS6 Avant station wagon, which is pumped up with even more power to go along with its increased utility.
The 2021 S6 now comes standard with 21-inch wheels with summer tires, Audi's Virtual Cockpit digital gauge display, and carbon fiber trim. The Premium Plus model's optional Executive package now includes adaptive cruise control and lane-keeping assist.
Upgrading to the Prestige model costs a little more but it unlocks a lot of the S6's best features, including a semi-autonomous driving mode, a head-up display, matrix-design LED headlamps, automatic high-beams, soft-close doors, a power-operated trunk lid, a leather-wrapped dashboard and center console, an in-cabin fragrance diffuser, and heated rear seats.
I'd add the 19-speaker Bang & Olufsen stereo system and the cool night vision feature that helps identify animals and pedestrians in the dark.
Four-zone automatic climate control is standard, as are a power-adjustable heated steering wheel, adjustable ambient lighting, diamond-stitched leather upholstery, and 12-way power-adjustable heated front seats.
While neither the National Highway Traffic Safety Administration (NHTSA) nor the Insurance Institute for Highway Safety (IIHS) have tested the 2020 S6 at the time of writing this post but they both have tested the A6, and it passed with flying colors.
In fact, IIHS named the A6 to its Top Safety Pick+ list for 2020 because of its available driver-assistance features. Those same features are offered on the S6, too.
If Audi's standard warranty seems a little basic, that's because is it. Rivals such as the BMW 8-series Gran Coupe and the two-door Lexus LC offer more value in the form of a longer complimentary scheduled maintenance program or power-train warranty.
Limited warranty covers four years or 50,000 miles
Power-train warranty covers four years or 50,000 miles
Complimentary maintenance is covered for one year or 10,000 miles.
