This has the potential to get interesting. Modular architectures are the darling of the industry currently, and why not, building several models from common components brings cost down and increases economies of scale. VW Group is the prime example here.
Nissan has skin in the game as well by the name of Common Module Family (CMF) which would of begun underpinning vehicles sometime during 2013. CMF will do its duty under mainstream vehicles, all the way from small saloons to SUV's.
The platform works on the basis of 4 modules, front underbody, rear underbody, engine compartment and cockpit. The idea is that a vehicle can and will be created by smashing together a combination of the 4 modules.
Where this gets interesting in relation to IDx is that Nissan has never outlined if CMF is capable of being both FWD and RWD, no distinction has been made to say yes this is front drive endeavour only meaning there is a very real possibility that the CMF will be exactly what underpins the IDx. I believe this is the only logical way that Nissan will be able to produce the IDx in a lightweight, cost efficient format.
hmm, it would make sense that the components are new, plus if they do that it will give them a good reason to expand on a small vehicle line up which could be great at a time like this since people want cheaper cars that still offer some of the great things found in higher priced vehicles.
the only thing that worries me about CMF is that there really is no indication of orientation. Know yes we can assume that CMF is versatile in that way, but every vehicle that has been talked about for CMF are replacements for existing FWD vehicles. Now obviously that doesn't rule out the possibilities, but I'm judging by actions at this point...
