Like many other carmakers lately, Mercedes-Benz is preparing consumers for a new model debut through a dedicated app for smart phones. In the German firm’s case, the new model is the upcoming 2012 A-Class premium hatchback, which will make its global premiere at the Geneva Motor Show in March.

To make things a bit more interesting, we learn that Mercedes will put several camouflaged 2012 A-Class hatchbacks in circulation in various German cities as part of a competition that will see one contestant winning a trip to the car’s unveiling in Geneva.

The A-Class prototypes will be fitted with a Quick Response (QR) code that interacts with a downloadable app from the Apple App Store or the Android Market. Entrants will have to use their phones to scan a badge from the QR codes in order to participate.

The app will be available for download in February. In the meantime, head over the break to watch the teaser video on the competition.
