Platform sharing is nothing new for the 14-year-old Renault-Nissan Alliance, but this partnership is set to introduce new modular platform components that will eventually underpin 11 Renault models and three Nissan vehicles by 2020. Rather than being a typical platform, the Common Module Family (CMF) actually represents five segments of a platform that can be used in various applications, and one of the first vehicles to use this architecture will be the 2014 Nissan Rogue (spy shots of which are shown below) when it arrives "in late 2013."

As pictured in the image above (click to expand), CMF is composed of four chassis component, principally the front underbody, rear underbody, engine bay and cockpit as well as a common electrical system. Besides the next-gen Rogue, future Nissan models to share CMF will include the Qashqai and X-Trail, while Renault models will start using the platform next year on vehicles including the Scénic and Laguna. The CMF architecture is expected to help the Alliance reduce the parts cost of a vehicle by up to 30 percent and reduce the entry cost by up to 40 percent. The official press release with more details about CMF, and what it means for Renault-Nissan, is posted below.

Common Module Family (CMF): A New Approach to Engineering for the Renault-Nissan Alliance

A source of increased competitiveness and synergies, CMF extends manufacturing commonalization to an unprecedented number of vehicles developed within the Alliance.

-CMF will generate an average 30-40% reduction in entry cost per model and 20-30% reduction in parts cost for the Alliance.
-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).

PARIS - A Common Module Family (CMF) is an engineering architecture that 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.

Therefore, a CMF is not a platform; it can involve several platforms. A platform is a horizontal segmentation; a CMF is a cross-sector concept.

For the Alliance: a new stage with different types of vehicles from different segments

CMF is 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.

CMF for the compact and large car segments: global coverage

CMF for the compact and large car segments will include 1.6 million vehicles per year and 14 models (11 Renault group + 3 Nissan):
-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 generates economies of scale and lowers costs within the Alliance to meet client demands for product diversity.

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 generates 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
-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 unprecedented coverage offered by the Alliance in terms of number of vehicles and geographical regions.

Jean-Michel Billig, Engineering, Quality & IT Director of Renault said: "With CMF, the investments in vehicle architecture and non-visible parts are mutualized, resulting in significant cost reductions that allow us to roll out our innovation policy in terms of environment, safety and new technologies for all our customers."

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."

      An interesting idea that I'm surprised hasn't been tried on a large scale before.

      40% reduced entry cost, thats the price for the consumer right? if so wow

      I work for the supplier that is building the transfer case for the new Rogue, and the same transfer case is going to be used in the Nissan Leaf as well. We are setting up the new production line right now. So, this is very interesting to me!

      /sigh i remember when Nissan was a Japanese Car company.... i miss those days.

          @Bryan -- no they're not 'more "euro"'. Unless you mean 'crappy', and that only applies to some Nissan models. And the Versa, at least, has a very good price for how austere it is.

          No, I'm not saying those other non-European brands are more European than Nissan. I'm saying Nissan is not particularly European. I don't think the others are either, even though each has partnerships of one kind or another with European companies. Volkswagen is more European than Nissan. Is that fair? I don't consider that a good thing but I think it's a true thing. I actually don't think it's bad that some Nissans are kind of crappy. They do a better job than most in offering low prices, which I really appreciate. A crappy car with a fair price is totally fine by me.

          Yep. And I don't mind, it's nice to have another Euro option besides Volkswagen. It's undeniable that Nissan's cars are much more "euro" than most other Japanese cars.

          think this will explain this better.

      Not trying to be a smart ass but I expected all automakers to use this approach to some extent. Some of these modules (front suspension, seats & dash) are often built by outside vendors so the modular approach is nothing new. Excessive use of the approach may increase costs. For example although the Ford Fiesta and Focus are similar in size there may still be money to be saved by having bespoke modules for each model. When the expected model run exceeds 500,000 units using an air conditioning plenum that is slightly oversized is wasteful. At this level of production the price/unit curve is a flat line and increasing the volume has little effect on the unit price. Also at these production levels the automaker dictates the vendor’s allowable profit and has the right to audit production and procurement documents to make sure it happens. What will really help Renault is to get rid of the feather bedding 40% of their workforce that provide no value.

      The story is obscure on the meaning of "entry cost." Digging through the release, it means "product + process engineering." It definitely does *not* mean a 30-40% reduction in the retail cost to the consumer. The point here is to reduce parts and engineering expenses to improve profit while (presumably) holding the line on price increases for the consumer. I would be very interested to read a hard analysis of how this approach compares to what VW is doing with its MQB and MSB architectures. But that's not what Autoblog does well, alas...will have to wait for Car/Automobile or maybe C&D to provide the fuller answers.

      Bring on the Datsun's to the US, we need quality affordable cars.
      • 1 Year Ago
      Doing the same as VW, should make for lighter cars and fun motors.
