For the past thirty year, tens of thousands of enthusiasts of Volkswagen Group cars assemble on the shores of Lake Worthersee in Austria to participate in the largest festival of its kind in the world. Over the years, Volkswagen and the other brands of the German group including Audi, Seat and Skoda, have used the show to unveil special concepts, new models and studies that hint at future production versions or accessories.

At this year’s event (June 1 to 4, 2011), the VW Group prepared several vehicles for the festival including the production VW Golf GTI 35 Edition with 235HP, the VW Golf Cabriolet GTI and R concepts, the wild 503HP Audi A1 Clubsport Quattro study, and the Skoda Fabia RS 2000 Convertible prototype. As you may have noticed, the company didn’t show much love for its Seat brand which was left to display its current lineup.

The official cars joined an army of privately owned tuned and classic VW Group vehicles. To put it simply, if you are a fan of the Volkswagen Group and especially of the Golf GTI, then Wörthersee was the place to be. You can get a taste of what went on in Austria in our extensive gallery after the jump.

For those of you that would also like to see the girls of the show, stay tuned, as we’ll bring you a dedicated gallery later on today.
