CMF is aimed at reducing manufacturing costs and competing with similar previous concepts as Volkswagen Group's MQB.[2] It consists of five groups of interchangeable, compatible modules: engine bay, cockpit, front underbody, rear underbody and electrical/electronic.[2] According to the companies involved in the development, CMF is not a conventional platform but rather a manufacturing system which can be applied to different vehicles.[5] The actual platforms are built combining a limited set of common modules: a single module can be used for different platforms, covering different classes of vehicles, and so allowing a greater standardisation of components between both Nissan, Renault and Mitsubishi.[6]
Applications
The Renault–Nissan Alliance announced various variants developed using CMF, which are CMF-C (D for large and mid-sized vehicles; examples are the third-generation Nissan X-Trail and the second-generation Nissan Qashqai), CMF-B for subcompacts/supermini, CMF-A for smaller vehicles, and CMF-EV for alliance wide BEV.[1] The CMF will initially be used in approximately 14 vehicle models worldwide with an estimated production of 1.6 million units annually.[7] The first CMF vehicles were introduced through 2013 with Nissan's CMF-C/D models.
CMF-A
The CMF-A platform underpins various vehicles in the A-segment or city car segment. The first CMF-A car, the Renault Kwid, was launched into the Indian market in September 2015.[2][8][9] The platform currently also supports electric powertrain, for the Renault City K-ZE and its rebadged models.
The CMF-A+ platform is a larger derivative of the CMF-A platform. The platform is mainly utilized for low-cost B-segment or subcompact vehicles for emerging markets.
The RMP platform is presented as a new evolution of the CMF-B LS platform. It is aimed at emerging markets. The first vehicle using it is the Renault Kardian.[25][26][27]
CMF-B EV (electric vehicle, also known as CMF-BEV, CMFB-EV or, since November 2023, as AmpR Small) is the CMF-B platform variant that has been adapted for low-cost B-segment battery electric vehicles. It shares approximately 1⁄2 the components of the CMF-B platform.[28] The CMF-B EV platform was designed to reduce production cost and increase vehicle efficiency compared to the B-segment Renault Zoe, which used a bespoke platform.[29] Two types of traction batteries using NMC chemistry are expected: "high-performance" and "affordable" variants,[28] with the goal of reducing battery cost below US$80/kW-hr by 2030.[30] In November 2023, Renault subsidiary Ampere renamed this platform to AmpR Small.[31]
The AmpR Medium platform (previously CMF-EV until November 2023) underpins battery electric vehicles.[41] It replaces the EV platform used by the Nissan Leaf. In November 2023, Renault subsidiary Ampere renamed this platform to AmpR Medium.[42]
