So the Volkswagen Group has its ultra-flexible MQB platform while PSA is just starting to use its equally modular EMP2 base. Mazda too isn’t far behind either with its SkyActiv-Chassis to call upon. Now the Renault-Nissan Alliance is taking the whole shared-vehicle architecture to a new level with its own Common Module Family (CMF) system.
This is not a simple do-it-all platform. It’s a new approach to engineering architecture using shared assembly of compatible Big Modules: engine bay, cockpit, front underbody, rear underbody and electrical/electronic layout. CMF can involve several platforms of various sizes – a universal cross-sector concept.
It offers opportunities for more carryover parts to be shared between vastly different types of vehicles, an exercise that has previously been limited to models within the same platform. Standardised components and shared modules will also lead to an increased number of possible vehicles per platform base.
Compact and large vehicles from both Nissan and Renault will benefit first from CMF as it’s implemented in stages between 2013 and 2020. The new system will generate an average of 30-40% reduction in entry cost per model plus 20-30% lower parts cost for the Alliance.
The initial wave will include 14 models, including three from Nissan starting late this year (next-generation X-Trail, Qashqai and US-only Rogue). Renault’s CMF model line-up will first consist of 2014 replacements for the Espace, Scénic and Laguna.

Saving to the car manufacturers itself, does it pass down the saving and cost to the end buyer ????
Depends on which country you live at.
Parts could become cheaper and easily available (stockists only need to stock one part for all Renault and Nissan cars, rather than 10…), cars _could_ become cheaper or they become better equipped. Fancy features like adaptive cruise control could find their way into small and affordable cars. etc. I do think car buyers will profit from it too.
Im not an automotive engineer.
Anyway, modular seems the way to go in building cars. However, for example, im quite puzzle on how CX-5 can share its platform with Mazda2(in skyactive chassis setup). Yes the modular setup can be stretch or shortened (in length) according to models. But how do they figure our the width of the car. Mazda2 for sure will have narrower built compared to CX-5.
Talking about modular, i believe Proton also have their own modular setup shared between Exora and Preve for example. Do they?
Any engineer kind to share?
14 models?
So the next navara / pathfinder will share concept with nissan march or renault clio?
Haha
