Renault-Nissan Alliance Develops New Vehicle Architecture
Renault-Nissan has released details of a new vehicle architecture system called “Common Module Family” (or “CMF”).
Technically speaking, the new CMF is not a platform, insofar as it can involve several platforms. A platform is a horizontal segmentation whereas a CMF is a cross-sector concept.
CMF will essentially create an “Alliance parts bank” that covers Renault/Nissan 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.
The Big Modules will be designed to fit into the pre-existing Alliance Integrated Manufacturing System (AIMS), which is a standard, flexible process that enables the same product to be manufactured at several different sites or many products to be manufactured at a single site (thereby enabling adjustments to global capacity and lowering entry costs).
The goal for the Alliance will be to increase the modules common to several platforms with a view to standardizing components and increasing the number of vehicles per platform. The sharing and carryover of parts between models and entities will generate economies of scale. As well as a 20%-30% reduction in component purchasing, the Alliance will further realise a 30-40% cost reduction in product and process engineering.
CMF will gradually be extended to Renault and Nissan ranges between 2013 and 2020. CMF will initially be applied to the compact and large car segments, which will include 1.6 million vehicles per year and a total of 14 models (3 from Nissan and 11 from the Renault group).
The Nissan vehicles will be released first in late 2013 and will include replacements for the Rogue, Qashqai and X-Trail models.
The first Renault vehicles, meanwhile, are set to be released in late 2014 and will include replacements for the Espace, Scénic and Laguna models.
Tsuyoshi Yamaguchi, Alliance Director responsible for engineering, said: “CMF opens a new era in engineering synergies for the Alliance. This will enable us to pursue volume efficiencies and introduce attractive new technologies in our products faster than before, creating additional value for our customers.”
