MINI is a British automotive brand owned by the BMW Group that has produced the successor of the original Mini in Oxford, England since April 2001. There are three body variants available: Hatchback, Convertible and Clubman (estate). The development of the first generation had been done between 1995 and 2001 by Rover Group in Gaydon, United Kingdom and BMW AG in Munich, Germany and was accompanied by continual contention between Rover and BMW. The car, whose first generation was designed by Frank Stephenson, is drawing inspiration from the original Mini, which was manufactured by the British Motor Corporation. The 2001 to 2006 model years included four hatchback models: the basic "Mini One", the diesel-engined "Mini One/D", the sportier "Mini Cooper" and the supercharged "Mini Cooper S". In November 2006 BMW released a re-engineered version of the Mini which is unofficially known as the "Mk II Mini". The Mk II is currently available as a hatchback and a wagon, (Clubman).
