The Renault/Nissan Alliance announced its Common Module Family (CMF) engineering architecture. CMF is not a platform; it can involve several platforms. A platform is a horizontal segmentation; a CMF is a cross-sector concept.
CMF covers Renault/Nissan Alliance vehicles, from one or more segments, based on the assembly of compatible Big Modules: engine bay, cockpit, front underbody, rear underbody and electrical/electronic architecture. CMF will be deployed across 5 continents in more than 10 countries through 2020. The first deployment of CMF, for the compact and large car segments, will cover 1.6 million vehicles per year and 14 models (11 Renault group + 3 Nissan).
To be a source of increased competitiveness and synergies, CMF extends manufacturing commonalization to an unprecedented number of vehicles developed within the Alliance. The Alliance partners calculate that CMF will generate an average 30-40% reduction in entry cost per model and 20-30% reduction in parts cost for the Alliance.
Renault and Nissan are characterizing CMF as an additional tool that goes further than carryovers on a single platform, to expand the product range. The trend will be to increase the modules common to several platforms with a view to standardizing components and increasing the number of vehicles per platform.
CMF will gradually be extended to Renault and Nissan ranges between 2013 and 2020. CMF will be first applied to the compact and large car segments, then to be followed by models in other segments.
The first Nissan vehicles will be released in late 2013: replacements for Rogue, Qashqai and X-Trail.
The first Renault vehicles will be released in late 2014: replacements for Espace, Scénic and Laguna.
CMF will create an “Alliance parts bank” that is just the right size for a varied product range as close as possible to customer needs.
Sharing and carryover of parts between models and entities will generate economies of scale; applying the system throughout volume production of the vehicles guarantees long-term performance.
CMF addresses all items of expenditure, through synergies, shared volumes, economies of scale and shared risks within the Alliance in:
Component purchasing: a 20%-30% cost reduction for the Alliance; and
Investment (a single entry cost): a 30-40% cost reduction in product + process engineering, with variations for Nissan and Renault.
Compared with the savings achieved by commonalization on the B platform (which was originally intended for Modus and Clio for Renault and Micra for Nissan), CMF generates economies of scale through the coverage offered by the Alliance in terms of number of vehicles and geographical regions.
