This is a good guide to how the production version would look.

The development of the Volkswagen Arteon estate, which might arrive as the Arteon Shooting Brake, takes place with very little camouflage when the upcoming long-roof model hits the road. These new spy shots provide a great look at the vehicle.  Look for a debut later this year.

In front, this vehicle appears to wear the production-ready parts, except for covering over the inlets in the corners, but this concealment doesn't do much to hide the actual design. In profile, the engineers add some tape to the rear portion of the window surround. At first glance, this alters the way the greenhouse looks but a little further investigation reveals what this element really looks like. At the back, zooming into the images reveals that there are taped panels on top of the taillights.

In addition to the standard model, the Arteon estate would allegedly get the R treatment to give VW a high-performance estate in the lineup again. Rumours indicate the model might use a new turbocharged version of the venerable VR6 that would make around 404 bhp (301 kilowatts). Other info suggests it would have a tuned version of the 2.0-litre turbocharged four-cylinder with 325 bhp (242 kW). We have to wait and see which report is true.
