The next-generation Audi A6 has been spied in Norway during testing this week, giving us a first glimpse of the new mid-sizer from Ingolstadt.
The curves of the current-generation car will make way for more angular lines, in a similar vein to Audi's most recent models.
At the front, the wider grille and slimmer headlights are the major differences from the model on sale today, while the rear is still a mystery as the photographer was unable to snap the vehicle from the back.
Like the current car, the A6 will be offered in both sedan and 'Avant' wagon body styles, though if the status quo is anything to go by, the wagon is unlikely to make it to Australia.
Powertrains are unknown at this point, though expect a mix of four-, six- and eight-cylinder turbocharged petrol and diesel engines.
The new A6 isn't likely to be revealed until some time in 2018, so stay tuned to CarAdvice for more updates in the meantime.
Update: Spy photographers have nabbed more images of the A6 prototype during testing, partially-revealing the rear of the next-generation model.
However, the tail-lights are pre-production units, so the overall look could change significantly as the A6 edges closer to its release - plus it's still concealed under the swirly black-and-white camouflage.
