It's all-but identical to the A7 Sportback's interior, and that can only be a good thing. The quality is top-notch throughout, with sumptuous materials and faultless fit and finish.
The sweeping design looks great, too, and a pop-up control screen that slides neatly out of the dashboard provides a neat trick to impress your passengers with. It reduces clutter when it's not in use, too.
Audi's MMI control system comes as standard. It's good, if not as intuitive as BMW's iDrive; getting used to the mass of switches around the controller takes time, and you have to take your eyes off the road to do so.
Despite being slightly lower, the new A6 has more headroom than even the tallest people are likely to need. There's also vast legroom, while the boot is well shaped and, at 530 litres, slightly larger than that in a BMW 5 Series.
Split/folding rear seatbacks are standard, too.
