The Audi A6 journey goes back to 1968 when the Audi 100 launched. This was a significant launch for Audi, especially as the 100 was the largest model to be manufactured since the brand’s revival in 1965. The Audi 100 was so successful, that parent company Volkswagen set up an additional production line at their Wolfsberg plant to handle the increased demand.

With increased demand, the range soon expanded with a selection of petrol and diesel engines alongside manual and automatic gearbox options. The original Audi 100 launched as a 4 door saloon, but was soon available as a coupe, 2 door saloon, hatchback and Avant (estate).

And 26 years later in 1994, the 100 name was retired, replaced with the A6 name we’re all familiar with today. From launch, the Audi A6 was and continues to be available as a spacious saloon or versatile Avant, both configurations are a popular used car buy.

Innovations include the Audi A6 Allroad. Originally coined the Audi Allroad, the A6 Allroad paired Audi’s legendary Quattro all-wheel-drive with the Avant body style and air suspension to create an all terrain, weather conquering car of choice.

Choose a fifth generation model - these were built between 2018 and 2025 and you’ll be treated to a selection of petrol and diesel engines, some with mild hybrid technology. All models are fitted with an automatic gearbox and available as a saloon or Avant.

Sixth generation models are powered by an electric motor - no Internal Combustion Engine (ICE) option is available. Instead, these are reserved for the Audi A5 and Audi A7 models.

“The legacy of the Audi A6 continues. From equipment and engines to meticulous build quality and attention to detail. The latest models are a technological marvel!” Ben Mills

Audi has perfected A6 development over a period spanning 50+ years. With so many configurations, engine options and specifications to choose from, the latest A6 models represent choice and value as a used buy.

Starting with the basics, used Audi A6 models are available as a 4 door Saloon or 5 door Avant (estate). Both models are impressively spacious and practical, the Avant however is more versatile providing greater flexibility with a flat, wide and spacious boot. If you’re travelling with large, bulky items, we recommend the Audi A6 Avant for the sheer amount of space and flexibility they provide.

All Audi A6 models from 2018 onwards (fifth generation) are equipped with an automatic gearbox - and it’s a great one. A 7 speed, dual clutch operation means changes are silky smooth and responsive while returning impressive fuel efficiency.

And, talking of fuel efficiency, the diesel engines in fifth generation models are the most fuel efficient yet. With mild hybrid technology, these engines not only save money at the pump, they also support engine coasting and starting for a smoother driving experience. If you travel on the Motorway regularly, intend on towing or travel 12,000 miles or more a year then we think you should consider a used Audi A6.

The petrol engines also feature this mild hybrid technology and are perfectly suited if you travel shorter distances, but need the additional space, comfort and luxury a nearly new Audi A6 provides.

Sixth generation Audi A6 cars are powered by electricity. From launch, these models are equipped with a 270kW electric motor developing 367 bhp. Power is sent to the rear wheels with a manufacturer range between 390 and 437 miles on a single charge. Charging is speedy too at 270kW DC - this means a 10 minute charge will add around 190 miles to your range.

Electric Audi A6 cars combine all the benefits of Internal Combustion Engine (ICE) Audi A6 models with the added environmental and low running cost benefits. Don’t forget to pair your electric Audi A6 with a Go Zero home charger to benefit from low price overnight charging.

If you’ve settled on a nearly new or used Audi A6 you’re in great company. All models are impressively equipped as standard with a choice of petrol or diesel in 5th generation models and electric in 6th generation models. All 5th generation models are equipped with mild hybrid technology making them some of the most fuel efficient and planet friendly engines yet.

Choose a 5th generation Audi A6 and you’ll be treated to sumptuous twin leather upholstery, Audi’s MMI Navigation and MMI Touch dual touchscreen systems, LED headlights, Audi Parking System Plus (front and rear sensors) and heated seats. S Line models add Matrix LED headlights (these are standard on later models), 19 inch alloys wheels, S Line sports seats and S line bodystyling pack.

And, if you want more, there’s good news! The Audi A6 was available with some fantastic option packs, we’ll detail some of the most popular right here. The most popular by far is Audi’s Technology Pack with the beautiful 12.3 inch Virtual Cockpit digital drivers display and Audi Phone Box (wireless smartphone charging). Later models also add a 360° camera, 730 watts Bang & Olufsen audio system, head-up display, extended multicoloured LED ambient lighting and Remote Parking Assistant Plus.

Some models are available with Technology Pack Pro - a £5,995 upgrade that adds heated rear seats, panoramic glass roof, rear USB charging ports and Advanced Key (keyless entry) to the above.
