As the UK basks in Indian summer sunshine Audi has just very appropriately removed the wraps from its most exhilarating RS convertible to date – the new 450PS RS 5 Cabriolet. Complementing the beauty and brawn of the RS 5 silhouette with a fast-acting lightweight fabric roof the new open-top will arguably offer the very best environment in which to savour the red-blooded 4.2-litre V8 shared with the RS 4 Avant. The new RS 5 Cabriolet opens for UK ordering in late 2012, and deliveries are expected to begin here next spring.
