The PF3 Platform was developed by engineers at PSA Peugeot Citroën for large- and medium-sized cars with front wheel drive and transverse engine.
The first car to use the PF3 platform was the 2001 Citroën C5. PSA PF3 was a global mid-size platform used by various models produced by Citroën and Peugeot.
PSA began to use the new EMP2 platform (instead of the PF3 platform) for all future models in 2013, 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 production of the second-generation Citroën C6 ended.
