What used Audi A6 saloon will I get for my budget?
How much does it cost to run a Audi A6 saloon?
The 2.0-litre diesel has an official average of 44.8mpg, compared with the 2.0-litre petrol's 34.5mpg - but be sure you'll cover enough miles to make the extra cost of the diesel worth paying. The 2.7-litre diesel is respectable at 40.9mpg, with the 3.0 V6 at 35.3mpg. These beat the rest of the petrol models, with the 2.4 V6 managing just 29.1mpg.
High emissions mean road tax cheap isn't cheap on any model, but a 2.0-litre TDIe diesel introduced in mid '08 is by far the cheapest to run, it emits just 139g/km of CO2 and covers 53.3mpg.
