Common Modular Platform

The Common Modular Platform (CMP), also known as EMP1, is a modular car platform which is jointly developed and used by French car manufacturer PSA, now Stellantis, and Chinese car manufacturer Dongfeng. It debuted in 2018 with the release of the DS 3 Crossback, the platform is mainly used by B-segment (supermini or subcompact) vehicles along with some entry level C-segment vehicles. For larger cars from the C-segment above, PSA uses the Efficient Modular Platform (EMP2). The CMP offers a high level of modularity with a choice of two track widths, three wheelbase lengths, three rear modules and the capability to offer several wheel diameters, allowing engineers and designers to introduce a broad range of body styles, from hatchbacks and saloons to SUVs. It has been extended for battery-electric vehicles as e-CMP and e-CMP2.
