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.

  • 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.

  • 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

FAQs

My car tax is free, do I need to do anything?

Even if the car is in a zero road tax band, you still need to register it as taxed each year. The process is the same, but you won’t be charged anything. So you’ll need to go online or to the Post Office and 'tax' it (it will show a £0 fee). It’s important to do that so the car is officially recorded as taxed.

How experienced and qualified are Carsa’s technicians?

Our technicians are highly qualified and experienced. They are trained professionals who specialise in inspecting and preparing used cars to a high standard. Every car undergoes a rigorous inspection by our technicians, who have lots of experience in the motor trade. In short, you can trust that knowledgeable, certified mechanics have checked over and serviced your car before sale.

Does Carsa offer GAP insurance?

No, we don’t offer GAP insurance. You would need to arrange GAP insurance separately if you want it.

Can I book a service through Carsa?

Yes. We we partner with HiQ to provide servicing, so you can absolutely book your car in with us for routine servicing. Just visit our Carsa Service website or call the service centre, and you can schedule a service appointment at a location that’s convenient for you. We’ll be happy to continue taking care of your car’s maintenance.

When will I receive the V5 logbook for my Carsa car?

The V5C logbook is sent to you by the DVLA after purchase. It usually takes a few weeks; typically you can expect it within up to 6-12 weeks by mail.

How and when will I receive my car’s service history?

We’ll provide the service history documents to you when you get the car. If it’s digital, we’ll give you a printout or email, and if the car has a service booklet, that will be in the car’s documents pack. Essentially, at the point of handover (collection or delivery), we’ll hand you any service records or tell you how to access them. So you’ll have the history in hand right away.

When will my next service be due?

It depends on the car’s recommended schedule. Typically, cars should be serviced once a year or roughly every 10,000-12,000 miles (whichever comes first). If we’ve just serviced the car before delivery, your next service would likely be due in about a year from that service date. We’ll let you know the last service date and any upcoming due dates when you purchase the car.

When will my next MOT be due?

If the car just had an MOT done as part of our prep, then your next MOT is due one year from that date. If it’s a nearly-new car under 3 years old that hasn’t needed an MOT yet, then its first MOT will be due when it turns 3 years old. We’ll let you know the MOT status and date when you buy the car, so you’ll know when to plan for the next one.
