The four shared projects first discussed have been whittled down to three, as PSA and GM will no longer co-develop a platform for the replacements for the Citroen C5, Peugeot 508 and Vauxhall Insignia.
However, PSA Peugeot Citroen and GM have furthered their tie-up by announcing that the new Vauxhall Zafira and Peugeot 3008, and Citroen C3 Picasso and Vauxhall Meriva will all be built on PSA platforms, with the larger two cars likely to use the new PSA modular EMP2 platform. The new models will begin appearing in 2016.
GM will take responsibility for developing both the new C3 Picasso and Meriva MPVs, while both firms are set to co-develop a new B-segment platform to replace cars like the Peugeot 208, Citroen C3 and Vauxhall Corsa. These models could also use the PSA-Bosch-developed Hybrid Air compressed air petrol hybrid system, also due in 2016.
The two firms will also collaborate on further improvements to PSA Peugeot Citroen's EB three-cylinder petrol engine used in the 208, and have signed a definitive deal for joint purchasing that should bring better economies of scale for PSA and GM brands.
