The PF3 Platform has been developed by engineers of the PSA Peugeot Citroën group for large and medium sized cars with front wheel drive and transverse engine.
The first application using the PF3 platform is the 2001 Citroën C5. PSA PF3 was a global mid-size platform used by various models produced by Citroën and Peugeot.
From 2013, PSA started to use the new EMP2 platform for future models, starting with the new Peugeot 308, except for collaborations with its partner Dongfeng for models specifically designed for the Chinese market.
It was phased out in 2023 when the second-generation Citroën C6 production ended.
