The Volkswagen (Passat) CC was one of the first 4 door coupes on the market. It was in its early days, also the only ‘cheap’ 4 door coupe you could buy. However the next generation could be sold as a Shooting Brake as well. You can view the rendering of the normal Volkswagen CC here
The shooting brake will get the same kind of styling like the Volkswagen CC. The rear will be different compared to the normal Passat wagon with a more sloping roofline, different rear lamps, bumper and tailgate.
