The brand new 2013 Mercedes-Benz A-Class will debut at March's Geneva motor show after extensive road testing in a QR Code livery (image below). No doubt inspired buy the success of the Mercedes-Benz QR Code race in Singapore the livery is part of a competition to win a trip for two to the world premiere of the A-Class in early March in Geneva. From the first week of February the QR Codes will resolve to a free app "the A-Class QR-Trophy" which allows participation in the competition and the collection of "badges". Badge collection is by scanning QR Codes which will be found in print and social media, with four badges completing the set and automatic entry into the draw. An initial competition trailer video can be seen below.
