Just last week, Audi released a teaser video featuring the new C8 Audi A6 ahead of its debut at next month’s Geneva Motor Show, and now the car has been caught in the most revealing series of spyshots yet. Although not much is different on the outside of this Avant wagon mule, these photos give us a first look at the interior, which, as expected, borrows many elements from the latest A7 and A8.

These include twin central touchscreens, the upper one to control infotainment functions such as navigation, media and vehicle settings, and the lower one used to tweak the car’s climate and comfort features. The row of buttons below the second touchscreen – such as those to select the drive select modes – are physical keys rather than the A7 and A8’s touch-sensitive controls, however.

Like we said earlier, the rest of this test prototype is similar to previous ones, sporting the same mini-A8 design. The lower edge of the headlights are kinked instead of straight as on its larger sibling, but the lighting signature, wide six-point “singleframe” grille, distinct shoulder line and prominent front and rear haunches are similar. The A7 and A8’s full-width tail lights aren’t anywhere to be found here, though.

The new A6 will likely be underpinned by the MLB Evo platform, which should see some significant weight savings. Expect the usual line-up of four-, six-cylinder petrol and diesel engines to be made available. If the recent Audi models are any indication, the brand’s new mild hybrid system (MHEV) will also be integrated into all powertrains. High-performance S and RS models should be introduced later on as well.
