Actions

Which Audi A6 generation should I buy?

The C8, sold from 2018, is the most modern and comes only with automatic gearboxes. The C7 of 2011 to 2018 costs less, and its later diesels meet Euro 6, which matters for London's ULEZ.

Is a used Audi A6 diesel ULEZ compliant?

Only if it meets Euro 6, which diesel cars do from about September 2015; check the advert or ask Audi with the registration. Petrol A6s comply from about 2006.

How much is road tax on a used Audi A6?

An A6 first registered from April 2017 pays £200 a year, plus a £440 supplement in years 2 to 6 if its list price was over £40,000, which higher-spec A6s often crossed. Older cars pay by their CO₂ band, from £20 to £790.

What engines does the new Audi A6 have?

The new A6 Saloon and Avant come with a 204PS TFSI petrol, a 204PS TDI diesel with quattro or a 299PS e-hybrid plug-in with quattro, all with S tronic. Trims run Sport, S line, Black Edition and Vorsprung.
