Audi has confirmed that it will be showcasing the fourth bodystyle in the third-gen Audi A3 range at Frankfurt 2013 this Sunday – the Audi A3 Cabriolet. The drop-top A3 will join the existing 3-door, 5-door (Sportback) and sedan variants, all based on the Volkswagen Group’s MQB platform.

But while we wait for the car to be unveiled this Sunday, our European spy photographers have already snapped the car in action, although it’s still wearing alot of camo. This prototype sports quad exhausts so it’s most likely a 300 PS turbocharged Audi S3 Cabriolet.
