Audi debuted the RS5 Cabriolet today via a live video premier. The drop-top features a V8 engine and ant hits 62mph in under 5 seconds. Not bad. Also quick, the time it takes to roll the soft top down. Just 15 seconds. And, it can even motorize while your driving (as long as your speed is under 31mph). Sudden rain? No problem the top is back up in 17 seconds. Click the thumbs for a full look.
