The mini-A8 styling is more evolutionary than revolutionary, but underneath the skin are some key changes.
Initially the A6 comes with a choice of four engines: a range-topping 3.0-litre petrol lump and three TDI units.
And because all new A6 engines are linked to efficiency-enhancing systems like start-stop and energy recovery the average consumption across the range has been dropped by 13 per cent. Importantly the A6 has also undergone a serious weight loss programme by adopting a composite steel-aluminium construction.
