Audi's A1 Convertible

It's not just the range-topping R8 that Audi is opening up on. The upcoming A1 city car will also get a convertible version, as well as a family of bodystyles.

First unveiled in concept form in 2007 and set to take on BMW’s MINI, the A1 will be released in less than a year priced just under £13,000.

But Audi bosses have already decided that the three-door will be swiftly followed by a five-door A1 Sportback, A1 convertible and mini-SUV models.

That variant will likely be badged Q1 to fit in with the firm’s larger 4x4 models. The move is aimed at pre-empting MINIs rollout of new models such as the Coupe and Roadster concepts shown at last month’s Frankfurt Motor Show.
