About the Audi A6

Audi have always been known for the sleek exteriors and interiors, their nimble handling, their durability and their high-class luxurious driving experiences. Both the Audi A and S lines have proven themselves to be the flagship models of Audi’s best design efforts, and they repeatedly win awards for design innovation and luxury road travel experiences.

Deciding to purchase a used Audi A6 can not only provide you one incredible specimen of a vehicle for a competitive price, but it can help you become a part of the prolonged and famed history of this prized manufacturer.

First introduced in 2004, the A6 served as the third generation of its midsize saloon. Noted for its large, singular grill, its proud presence on the road and its 4.2 Litre V8 engine, the Audi A6 impression then, and it impresses to this day. Since then, the over fifteen years of innovation and prideful design has led to a vehicle that many people would love to own - and with our used car listings, now they have the chance to do so:

Used Audi A6 Options

From 2018-present, the A6 is now on its 8th generation, and this offers a range of excellent diesel or petrol options. However, it’s also now possible to sport the Audi A6 hybrid, with its 55 TFSI e Quattro 7AT 252hp engine.

There are four trim levels available for the A6, Premium, Sport, Premium Plus and Prestige, with the S line taking precedence over the sport range.

With different leather trimmings available including widening infotainment screen systems, and enhanced boot room thanks to declinable seats, you can customize near every-level of the A6 with confidence.

The A6 has two engines outside of the hybrid, including a 2.0 litre 4 cylinder serving as the entry-level option, and the even more powerful 3.0 6-cylinder supercharged variant. You can expect both to carry eight speed automatic transmissions for driving comfort and convenience.

If looking for a more down to earth and powerful make, the Audi A6 All road comes with a raised ride height profile and plastic cladding - this is more suitable for off-road or rural environments. Furthermore, the Audi A6 Avant and Saloon variants are possible options, providing a larger estate presence with a wagon-like body shape.
