DUI as in 'designing under the influence'... You see, some things in this life, such as asking a German tuner to create a one-off special for a German brewery, are just not meant to be. We understand that this is a promotional vehicle with Radeberger Pilsner's traditional black and gold color scheme but, well, let's just say that the photos speak for themselves. Anyway, aside from the ABT two-tone bodykit, chunky alloy wheels and logos, the special A5 Cabrio gets a red leather interior with Radeberger's name embroidered on the headrests and the floor mats.

ABT also equipped the A5 Convertible with a pair of LCD screens that are mounted on the back of the front headrests while another highlight is the drink cooler located under the center armrest.

Pop up the bonnet and you'll find a tweaked version of Audi's 2.0-liter TFSI that has received a series of upgrades boosting output to 275HP, up from 180HP. ABT says that the drop top A5 can accelerate from zero to 100 km/h (62mph) in 6.7 seconds and achieve a maximum speed of 271 km/h or 169 mph. The ride and handling are improved as well with brake and suspension upgrades.

The one-off ABT Radeberger Audi A5 Cabrio special will be raffled off in Germany sometime before the end of the year.
