Audi A1 Cabriolet renderings

According to AutoExpress the future A1 Cabriolet will look exactly like this when will make its official debut at the 2009 Frankfurt Motor Show. When will go on sale next year, its biggest competitor will be Mini.

Under the hood of the future A1 Cabriolet, Audi will offer both 140bhp and 170bhp 1.4 TSI turbo and supercharged units currently found in the Golf GT Sport. These will use a six-speed double-clutch gearbox powering the front wheels.

TSI versions are set to be sales leaders, due to their appealing combination of refinement, performance and economy. A 150bhp 1.8 turbo engine will line up alongside the clever TSI unit, and the range will also include an entry-level 1.6 with 102bhp. Two 2.0-litre TDI oil-burners will feature, rated at 140bhp and 170bhp.

The S1 version will be powered by the same engine as the 261bhp S3 when it arrives in 2011.
