Rover 75 Mars

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, which would have been a departure from the BMW tradition of rear-wheel drive on the majority of its models. As the 75 took shape, this core engineering was passed over to Rover and evolved into the Rover 75 structure[citation needed]. The tunnel concept, along with the rear suspension system, was also used by the Rover engineers for the design of the Mini.
