Both cars are based on the vRS production models, and get a range of aerodynamic and more general styling tweaks.
The Fabia RS+ takes its design cues from the S2000-spec IRC rally car (which will also be at the show) with black spoilers front and rear, a black grille and smoked headlights. Most reminiscent of the rally car are the chunky air vents set into the bonnet, and the rear diffuser. There's also a grey and lime-green two-tone finish inside and out.
But although the cars aren't much more than a styling exercise, the move signals just how serious the VW group is about turning Skoda into a brand with genuine performance kudos - the Worthersee event is a Mecca for fans of fast VWs.
