Common Modular Platform

The Common Modular Platform (CMP) represents a flexible automotive architecture co-created by the French automaker PSA Group (currently integrated into Stellantis) and the Chinese manufacturer Dongfeng Motor Corporation. Introduced in 2018 alongside the DS 3 (formerly DS 3 Crossback), CMP is primarily designed for B-segment vehicles, such as subcompact or supermini cars, as well as select entry-level C-segment models. For larger vehicles in the C-segment and beyond, Stellantis utilizes the Efficient Modular Platform (EMP2).

CMP is engineered to offer extensive modularity, featuring options including two distinct track widths, three wheelbase variations, three types of rear modules, and multiple wheel diameter choices. This versatility accommodates a range of body formats like hatchbacks, sedans, and SUVs. Furthermore, CMP has been adapted into electric variants known as e-CMP and e-CMP2 to support battery-electric vehicles.

History

The collaboration between PSA and Dongfeng to create this platform was initiated in March 2014. By 2015, both parties had invested €200 million into the development, with PSA contributing 60% and Dongfeng 40%. A group of engineers from Dongfeng integrated into PSA’s research and development center located in Vélizy, near Paris. Together, they also developed the electric version e-CMP, engineered for an approximate driving range of 450 km and capable of charging rates that add up to 12 km of range per minute. The inaugural e-CMP models debuted in 2019.

e-CMP

The CMP architecture also underpins battery-electric vehicles marketed under the e-CMP designation, sharing production lines with conventional variants. First-generation e-CMP models are equipped with an electric motor paired with a lithium-ion battery pack rated at 50 kWh gross capacity (46.3 kWh usable) and incorporate an advanced heat pump system.

The second-generation e-CMP features enhancements such as the eMotors M3 traction motor delivering increased power output and torque, boosting overall efficiency. This motor is manufactured by eMotors, a joint venture between Stellantis and Nidec. Additionally, battery capacity has been upgraded to 54 kWh gross (51 kWh net), utilizing NMC battery chemistry.

Smart Car Platform

The Smart Car Platform represents an electrified adaptation of the CMP platform, created by Tata Consultancy Services for the PSA Group. It provides a more energy-efficient option compared to other STLA modular frameworks, with a specific focus on battery electric vehicles. This platform will underpin seven models from Stellantis, including the forthcoming Fiat Grande Panda, Citroën C3 Aircross, and Opel Frontera. Equipped with electric motors rated at 43 or 83 kW and LiFePO4 batteries ranging from 29 to 44 kWh, the platform allows for driving distances up to 320 kilometers.

STLA Small

Scheduled for release in 2026, the STLA Small platform will support new models such as:
