Interior specialist Carlex Design has revealed another custom cabin, this time created for the owner of a new Audi A6 Avant. Dubbed the A6 Honeycomb for obvious reasons, the driving space of the luxury wagon has been completely overhauled using black and red nappa leather and honeycomb stitching, which the Polish stylist said was particularly challenging to apply to the car seats. As you can see, the result makes for one highly exclusive interior.
