Production of the Rover and MG branded models ceased in 2005 when manufacturer MG Rover entered administration. However, 'new' models with delivery mileage are still being registered. The Chinese manufacturer SAIC has started production of their version of the 75, called the Roewe 750, which is a slightly stretched version of the standard R40 design developed from designs purchased from MG Rover Group in 2004. Rival Chinese manufacturer Nanjing Automobile Group (the owner of the MG brand and MGR tooling) has started production of the MG 7. The latter vehicle cannot be branded as a Rover because NAC-MG do not own the rights to the brand, which Ford purchased in 2006. This version is essentially the same as the last models built in Britain by MG Rover Group.
Both the MG 7 and Roewe 750 have started production in China.
The Rover 75 started life as a project for the complete re-skin of the Rover 600, under the control of Rover Group designer Richard Woolley, but following the BMW takeover it was quickly decided that the Rover 600 would not be re-skinned but replaced by an entirely new model. Work on the new model, codenamed 'R40' progressed well with little operational interference from BMW, with the basic design having received an enthusiastic response from BMW management and both BMW and Rover believing that a retro design would be the ideal choice for Rover. At the same time it offered a distinct marketing separation from the E46 BMW 3 Series in the executive segment.
Under the skin, there was a first attempt at considerable component and concept sharing with BMW to replace the input of the previous partner Honda. To replace the previously employed Perkins-developed engines that were efficient, but noisey, BMW provided its own common rail motor (known in the Rover 75 as the M47R). This diesel engine was a mildly de-tuned BMW 2.0 litre turbodiesel, the same core engine being used at the same time in the 3 & 5-Series, and the Land-Rover Freelander.
Petrol engines provided were Rovers own K series in 4 cylinder form, of 1.8 litre displacement, with DOHC 16 valve form with Rover/ Motorola MEMS engine management. The quad cam KV6 was provided in 2.0 and 2.5 litre displacement with 24 valves and Siemens engine management. The 2.0 litre was dropped on introduction of the 1.8 litre turbo as these were more favourable to the UK company fleet market (company cars are taxed by the UK Government according to carbon dioxide emissions). Gear boxes on all manual cars were Getrag 5 speed fed via a hydraulic clutch, and automatic cars were fitted with a 5 speed Jatco unit.
