The Rover 75 is an executive car produced by British automobile manufacturers Rover Group and later by MG Rover, under the Rover marque. The Rover 75 was available with front-wheel drive in either a saloon or estate body style and latterly, in long-wheelbase form and a rear-wheel drive, V8-engined specification. In 2001, an MG-branded version was launched by MG Rover, called the MG ZT. Rover 75s were built by the Rover Group at Cowley, Oxfordshire, for just a year. After owner BMW divested its interests in Rover, the 75 was built by the new MG Rover Group at their Longbridge site in Birmingham. The Rover 75 was unveiled to the public at the 1998 Birmingham Motor Show, with deliveries commencing in February 1999. Production of the Rover and later MG badged models ceased on 8 April 2005 when manufacturer MG Rover Group entered administration. ==History== The Rover 75 started life as part of a group of three new designs for the company under the guidance of Richard Woolley; a large saloon codenamed ''Flagship'', a smaller vehicle (with the codename of ''Eric''), and the 75. Of these only the 75 concept progressed. The initial aim was to re-skin the Rover 600 but following the BMW takeover it was quickly decided that this platform would not be re-used but replaced by an entirely new model. Work on the new model, codenamed ''R40'', progressed well with little operational interference from BMW; the styling received an enthusiastic response from the management and both companies believed the classical look would be the ideal direction for Rover. Revolutionary new design processes were adopted, including the 3D virtual reality assembly simulation "ebuild" techniques, ensuring the car would achieve class leading build quality when series production started. Under the lauded styling was a range of petrol and diesel engines from 1.8- to 2.5-litre sizes. Petrol engines provided were Rover's 4-cylinder K series in 1.8-litre guise and the quad cam KV6, offered in either short-stroke 2.0 or revised 2.5-litre formats. The 2.0-litre was later dropped on introduction of the 1.8-litre turbo for emissions purposes. Transmissions on all models were either the Getrag 283 5-speed manual, supplied from the company's new facility in Bari, Italy, or the JATCO 5-speed automatic unit—one of the first transverse engine deployments made with this feature. Braking was in the form of all-round discs, complemented with a Bosch 5.7 4-channel ABS system and electronic brake force distribution. The parking brake was a cable operated drum integral within the rear discs. Suspension was a MacPherson strut arrangement at the front, anchored by lower alloy L-arms. The wide spacing of the mounting points, compliant bushings and a perimeter subframe gave the model a cushioned yet precise ride with relaxed handling that could be tuned for different markets or model derivatives such as the later MG ZT. The rear suspension, after a period of uncertainty during development, was eventually a version of BMW's Z-Axle arrangement first featured on the 1988 Z1 sports car. At the time of the launch there had been speculation within the media that the Rover 75 used the BMW 5-Series platform, perhaps due to the overall size of the model, the apparent presence of a transmission tunnel and the use of the parent company's rear suspension system. This was in fact not the case: Rover engineers had used the concept of incorporating a central tunnel which had been explored by BMW as part of their own research into front-wheel-drive chassis design. As the 75 took shape, this core engineering was passed over to Rover and evolved into the Rover 75 structure . The tunnel concept, along with the rear suspension system, was also used by the Rover engineers for the design of the Mini. At launch the Rover 75 quickly attracted praise for its styling and design integrity. Some critics of the car labelled its styling too "retro", suggesting it had been designed with an older buyer in mind, and was not sporting enough when compared to the competition. However, the 75 won a series of international awards including various "most beautiful car" awards, including one in Italy. Assembly originally took place at Cowley but in 2000, following the sale of the company by BMW to Phoenix Venture Holdings, production was moved to Longbridge in Birmingham, England. 2001 saw the introduction of the Rover 75 Tourer (developed alongside the saloon but never authorised for production by BMW), swiftly followed by the MG ZT and MG ZT-T, more sporting interpretations of the model, differentiated by modified, sporting chassis settings and colour and trim derivatives . Between 2000 and 2003, there were few changes to the range: the most significant was the replacement of the 2-litre V6 engine by a low-pressure-turbocharged version of the 1.8-litre 4-cylinder engine. The introduction of the 'greener' 1.8-litre turbo greatly benefited British company car drivers who are taxed on carbon dioxide emissions. A customisation programme, ''Monogram'', was launched, allowing buyers to order their car in a wider range of exterior paint colours and finishes, different interior trims and with optional extras installed during production . Rather surprisingly, it was offered for sale in Mexico, making it the first Rover to be sold in North America since the Sterling. From June 2002 a factory-approved dual fuel petrol-liquid petroleum gas conversion was available in the UK on 1.8 and 2.5 litre models. The LPG conversion was an after-market undertaking approved by MG Rover. Developed by EcoGas Systems Ltd and Landi Renzo S.R.L. in conjunction with MG Rover Powertrain Limited, the conversion was ordered from Rover dealerships, the cars retaining the three-year factory warranty. The retail price of the conversion was £2,195, but in an effort to encourage LPG use for transport for ecological reasons the UK Government offered a Powershift Rebate of some 60% of the conversion cost. When running on LPG the Rover 75 suffers only a slight reduction in performance compared to running on petrol; LPG fuel consumption is also slightly higher than when running on petrol but this is more than offset by the greatly reduced cost of the fuel. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rover 75」の詳細全文を読む スポンサード リンク
