PSA PF1 platform


The PSA PF1 platform is a global subcompact automobile platform originally developed by the French automaker PSA, now Stellantis. It has been the foundation for a wide range of B-segment cars produced since the early 2000s.

Overview

The PF1 platform was designed to underpin small cars, offering flexibility to support various body styles such as hatchbacks, sedans, crossovers, and small vans. Its layout typically features a transverse front-engine, front-wheel-drive configuration, though some derivatives were engineered with all-wheel drive.
While PF1 was primarily used for passenger vehicles, it also served as the basis for light commercial vehicles, reflecting PSA’s strategy of maximizing economies of scale.

Applications

Vehicles based on the PF1 platform include several popular models across the Peugeot, Citroën, DS, Opel, and Vauxhall brands. Notable examples include:
This widespread adoption made PF1 one of PSA’s most commercially important architectures for over a decade.

Successor platforms

As automotive technology and regulatory requirements evolved, PF1 began to be phased out in favor of more modern and modular architectures. Its direct successor is the CMP, co-developed by PSA and the Chinese manufacturer Dongfeng. CMP supports both internal combustion engine and electric powertrains, enabling Stellantis brands to transition into electrification.
Larger PSA models during the PF1 era were based on the PF2 and PF3 platforms, covering compact and mid-size segments respectively.

Legacy

The PF1 platform played a significant role in establishing PSA’s presence in key global markets, especially in Europe, South America, and select Asian regions. Its derivatives helped Peugeot and Citroën maintain strong positions in the subcompact market, a vital segment in terms of sales volume.
