MINI is getting ‘roofless’ with its Cooper S – and these are the best picutures yet of the sporty drop-top. Our spies have managed to spot the flagship ‘S’ version of the Cooper almost completely undisguised on test in Germany, and it looks like MINI is onto another winner.Like previous versions, the new Cooper S Convertible gets a mulit-layered fabric roof and engineers will be working hard to ensure the newcomer offers as much interior refinement as the hard-top version.Gone are the trademark roll hoops of the previous version – MINI has decided to replace them with a a solid roll-over bar that pops up in the event of an accident, but otherwise hides behind the rear-seat backrests.With the top down, the C-pillar is just as wide and prominent as in the current model, so unfortunately rear visibility hasn’t been improved, but the new top should stow better than in the current model. Just like the tin-top, the Convertible gets the same 1.6-litre turbo delivering 175bhp – enough for a 0-60mph time of around seven seconds. Along with the rest of the Convertible range, the Cooper S will make its first appearance at the Geneva Motor Show in March. For more detail click here.
