Why the Audi S6 Avant is the executive performance estate with more to offer

Spacious estate body with sporting style

The S6 Avant brings together Audi’s elegant design with subtle sporting touches, including quad exhaust pipes, wider air intakes and S-specific detailing. The interior is refined and full of premium materials, with room to seat five adults in comfort.

With 565 litres of boot space, expandable to over 1,680 litres, it offers all the practicality you’d expect from a family estate, while maintaining a sleek and purposeful stance on the road.

Engines and performance

The most recent UK S6 Avant models feature a powerful diesel engine designed for smooth, high-speed touring and better efficiency:

  • 3.0 litre V6 TDI mild-hybrid diesel
  • 344 PS and 700 Nm of torque
  • 0 to 62 mph in just 5.1 seconds
  • 8-speed Tiptronic automatic transmission
  • quattro all-wheel drive for confident grip in all conditions
  • All-wheel steering on selected trims for greater agility

Earlier S6 Avants were powered by petrol V8 and V6 engines, offering even more punch for performance-focused drivers.

Technology and interior features

Audi has equipped the S6 Avant with top-tier technology and comfort features. Depending on model year and trim, equipment may include:

  • Twin touchscreen MMI Navigation Plus system
  • Audi Virtual Cockpit digital display
  • Bang & Olufsen premium sound system
  • Apple CarPlay and Android Auto
  • Heated and ventilated sports seats with memory function
  • LED or Matrix LED headlights with dynamic indicators
  • Adaptive cruise control, head-up display and night vision assist (on higher trims)

Everything inside the S6 Avant is designed to keep you connected, relaxed and in control at all times.

Trim levels and model options

The Audi S6 Avant is available in a selection of high-spec trims:

  • S6 Avant — Comes well equipped with sports seats, LED lights, navigation and quattro as standard
  • Black Edition — Adds dark styling accents, privacy glass, gloss black grille and 20 inch alloys
  • Vorsprung — Top-tier trim with panoramic sunroof, full assist package, air suspension and upgraded sound system
  • TDI (2019 onward) — Focused on high torque and long-distance comfort
  • Older V8 or V6 petrol models — For drivers prioritising raw performance and petrol power

Each version offers an excellent mix of space, luxury and sharp performance.

Why choose a used Audi S6 Avant for sale on finance?
