Its done some significant damage to FCA share price since the market opened, might be time to spend a few quid and wait for it to recover
I think its hard to see what's going to happen at the moment. Obviously PSA carries huge weight in europe, and FCA do in the americas and asia with a relatively small business in europe by comparison. If I had to make a prediction it would be that fiat might disappear from Europe and be more of a developing countries brand in places like south America. I think we'll see Fiat dealerships being absorbed by Peugeot dealers before long.
FCA has spend huge sums buying CO2 credits from Tesla. Who knows, maybe its stood them in good position to buy Tesla batteries and control systems for use in Fiat cars. Fiat could certainly show Tesla a lot about how to make small cars people want to own (rather than rent).
There's also the other partnerships to take into account as well: I believe that Fiat work with Renault-Nissan and Mitsubishi in commercial vehicles, as well as the existing, and old, Ducato/Boxer/Relay collaboration. And the partnership between PSA and Toyota, which resulted in the Aygo/C1/108, and I believe there's shared vans and other engines as well. That I think might cause issues in the future.
The one silver lining I can see is that the planets have aligned so that Citroen own Maserati again! Maybe we can expect some more weird and wonderful things in the future
But Big Auto will struggle with batteries and control software. I guess the issues are
Can Tesla make enough to supply others?
Is Tesla interested in allowing the likes of Fiat to manufacture them under licence?
