While the Renault-Nissan Alliance is apparently hitting a rough patch, the engagement between PSA and FCA seems to be happening in "little ponies and rainbow" mode. The expected divorce of the Sevel joint venture will eventually not occur (or at least not until a few years)...
But even if preparing for a happy marriage, PSA/FCA will have some work to do in the next months/years in order to optimize their union: for now, the wannabe 4th world automotive builder has to deal with 14 makes, 22 platforms, and 54 factories. Not to mention 2 Renault based vans (Opel Movano & Fiat Talento)...
