General Motors and PSA Peugeot-Citroën have announced that they will co-develop four new platforms as part of their alliance.  As previously reported, the first jointly-developed models will hit showrooms in 2016 at the very earliest.
The partners' first platform will underpin a compact Opel/Vauxhall MPV as well as a Peugeot crossover.  The MPV will likely replace the Opel Meriva, but the positioning of the Peugeot crossover remains a mystery.  The automaker is scheduled to launch a crossover called 2008 next year but it will be based on the 208 hatchback.
The second platform will underpin a small MPV built by both Opel/Vauxhall and Citroën.  For the latter, the MPV will replace the popular C3 Picasso.
The partners' third common platform will spawn an inexpensive small car built by Opel/Vauxhall, Peugeot and Citroën.  Aimed primarily at city-dwelling buyers, it will be sold in many markets outside of Europe.
Lastly, the two partners will develop a platform that will underpin the next generation of Opel/Vauxhall's Insignia, the next Peugeot 508 and the third installment of Citroën's C5.  The current Insignia shares its Epsilon II platform with the Buick Regal, which means that its replacement might also ride on the partners' fourth platform.
GM and PSA have not ruled out co-developing more platform but they are waiting to launch their first jointly-developed models before making any further decisions.
