The Mini Convertible was presented at the 2004 Geneva Motor Show. Gert Volker Hildebrand also played a key role in the development of this variant.[26] The convertible has a fully automatic fabric top which, like a sliding roof, can only be partially opened. The tailgate folds down like a pick-up truck, as was the case with the classic Mini. The rear window is made of glass and has a window heater. The Mini Convertible was introduced as the One, Cooper and Cooper S.
