ever produced by Nanjing Automotive. Security Ratings Rover 45 models were tested on three separate occasions by Thatcham's New Vehicle Security Ratings (NVSR) organisation, and achieved the following ratings: Powertrain These were the engines available for the Rover 400 (1995–1999) and Rover 45 (2000–2005): Replacement model projects R30 During the end of the 1990s, replacements for the Rover 25 and 45 models were developed by Rover Group under the codename R30. Intended for launch in 2003 as the Rover 35 and 55, these would have been based on an all new platform. At launch, these would have used K-series engines, but new Valvetronic engines were anticipated to be introduced by 2006. The R30 Project was cancelled, when BMW divested its ownership of Rover Group in March 2000. It is possible that some of the development work may eventually have benefited the BMW 1 Series. RD/X60 Following the termination of the R30 Project, from 2001, MG Rover planned to replace the 45 with a model range based on the Rover 75 platform. Collectively referred to as the RD/X60 project (sometimes also written RDX60), the range was intended to comprise the following variants: RD60: Rover hatchback X60: MG hatchback RD61: Rover saloon RD62: Rover "tourer" estate A preview of how the RD62 "Tourer" might appear was given at the 2002 Geneva Motor Show in the form of the Rover TCV (Tourer Concept Vehicle) concept car. During the design process, MG Rover's design partner Tom Walkinshaw Racing (TWR) went into administration. MG Rover lost access to most of the computer aided design work for their new vehicle. Efforts were made to reclaim these from the administrators, however, the resulting uncertainty and delays made it impossible to progress with the project. The abortive SAIC Deal of August 2004 was to have included bringing a replacement for the ageing 45 to market, and the RD/X60 was a likely candidate for this. Ultimately, no such joint venture was entered into. After MG Rover's collapse, SAIC bought some of the company's intellectual property, and released a concept called the Roewe W2. Like the RD/X60, this was partly based on the platform of the Rover 75. The W2 entered production in April 2008, as the Roewe 550. A hatchback derivative of the 550 was announced in November 2009, as the MG6.
