filter as well as uprated suspension. The car also had one-of-a-kind racing wheels. The Mk I Mini One, Cooper and Cooper S used some version of the reliable, Brazilian-built Tritec engine, co-developed by Chrysler & BMW; the Mini One D used a Toyota-built 1ND-TV diesel engine. In August 2006, BMW announced that future engines would be built in the UK, making the car essentially British-built again; final assembly took place at Oxford, and the body pressings were made in nearby Swindon at BMW's Swindon Pressings Ltd subsidiary. The last Mk I variant was the Mini Cooper S with John Cooper Works GP Kit: a light-weight, quasi-race-prepped John Cooper Works model. Hand-finished by Bertone in Italy, it was offered as a limited-production run of 2,000 cars during the 2006 model year, with 444 of those originally intended for the UK market (although ultimately, 459 were sold). Mini Convertible/Cabrio (2005 to 2008) At the 2004 Salon International de l'Auto, Mini introduced a convertible model which was released in the 2005 model year and available in One, Cooper and Cooper S trim versions. The convertible roof is fully automatic—an unusual feature in such a small car—and can be opened partially to act as a sunroof whilst the car is driving at speed. The convertible model forsakes the rear hatchback of the Hardtop Mini, replacing it with a drop down 'tailgate' that is reminiscent of the classic Mini—it incorporates similarly prominent external hinges, and with the roof in the closed position, the rear roof section and luggage shelf can be raised with two handles, semi-tailgate style, to access the luggage space easier. The convertible also adds two small power windows for the rear seat passengers which are lowered automatically when the roof opens. The roof is made from a heavy cloth, with many layers of insulation; the rear window is glass with an integral heater/defroster, but no washer or wiper. At the 2007 North American International Auto Show, Mini introduced the limited edition Mini Cooper S Sidewalk Convertible. It had a top speed of and accelerates from in 7.9 seconds. The engine provides and of torque. Mini Hatch/Hardtop (2007 to 2014) Mini introduced an all-new second generation of the Hardtop/Hatch model in November 2006, on a re-engineered platform incorporating many stylistic and engineering changes. It utilises the Prince engine, the architecture of which is shared with PSA Peugeot Citroën and is designed to be
