Ownership cost
What used Audi A6 saloon will I get for my budget?
You can find a good used A6 of 2018 vintage for between £22,000 and £25,000, depending on engine and trim, which is a reasonable saving on the price of a new one. Spend between £25,000 and £32,000 on a 2019 model from a franchised dealer, with a nominal mileage, again, a small saving on the new price. Expect to spend between £30,000 and £35,000 on a 2020 model.
How much does it cost to run a Audi A6 saloon?
MPG
Thanks to its hybrid technology, the CO2 emissions are sensible and its average fuel consumption is respectable, too. The 40 TDI puts out just 117g/km, and when we tested the economy we managed an average of 46.8mpg; both figures are better than its main rivals the BMW 520d and the Mercedes E 220 d can manage. The V6 diesel is reasonably economical too, considering its performance, but the V6 petrols are both thirsty old Hectors.
Car tax
All examples of this generation of A6 were registered after April 2017 so attract a flat-rate fee, currently £150 a year, plus an additional cost for cars that cost more than £40,000 when new, currently £325 a year. To find out more about the current road tax costs, click here.
Servicing
Examples that are over three years old will qualify for Audi’s fixed-price servicing, which costs from £185 for a minor service and £355 for a major one, based on cars with a 2.0-litre engine. A6s with larger engines will cost £215 and £409 for the same level of work.
Insurance groups
Insurance groups for the A6 are slightly higher than the equivalent models from BMW and Mercedes, with 2.0-litre diesels starting in group 33; the more powerful 3.0-litre BiTDI in group 44, followed by the most potent RS6 in group 50.
