Rolls would never tolerate a folding hard-top roof – imagine how big the Dawn’s back side would be – so canvas it is. But not any old canvas. This roof features six layers, and has what’s called a ‘French seam’ for maximum sound insulation. It folds away in 22 seconds into a space similar in size to the area a BMW 2-Series convertible’s roof disappears into, and can do so at speeds up to 30mph. That’s Olympic gold medal-winning levels of showing off. It also does its thing in complete silence. A ‘silent ballet’, says Rolls. Except that ballet dancers make more noise, as they shuffle and squeak about the stage.
