From the web:
If we read correctly the smoke signals that rise from the Weissach think tank, the new project, which is codenamed 960, has nothing much to do with the high-tech 918 Spyder. Instead, Porsche is moving heaven and earth to make 960 the lead car for the new platform. Although it still has not been signed off, due to political issues and a lack of a firm commitment on part of the other brands involved, the new platform, called
Mimo, is known in-house as MSB-M, short for modular sports car matrix, mid-engine version. Earmarked to go into production in just over four years, the Porsche 960 (for lack of a better designation) would still share components with the next 911 due in 2018. How is that? Because MSB-M incorporates a second bloodline labeled MSB-H with the H standing for Heckmotor, German for rear-engine.
