"The group will include 14 brands: Abarth, Alfa Romeo, Chrysler, Citroën, Dodge, DS, Fiat, Jeep, Lancia, Maserati, Opel, Peugeot, Ram and Vauxhall." (Thank you, Google)

It's quite fun to speculate on which brands will survive. Even using the common platforms as they have been, there are still extra costs that could be saved with fewer brands, each with its own USP. Such as;

Fiat - 500 for city chi-chi; some form of Panda as a Dacia rival.

Peugeot / Citroen - I think both have their following in France and will become more distinctive and different, but still sell.

DS - I've never seen the point of this brand.

Alfa and Lancia - one or the other, not both.

Maserati and Abarth - I should think these will depend on whether they can make money.

Jeep and RAM - enough following in the USA I'm sure, but possibly not Chrysler. I don't know about Dodge - do they sell lots of SUVs?

And Vauxhall / Opel - I can't think of any model that can do anything that the equivalent Peugeot can't.

Hopefully someone with more knowledge of the industry can come along and correct me if I'm wrong.

BTW - have all the brands and GM, other than servicing/maintenance (in which case, who do they get parts from?) gone from Down Under (Holden). I don't think that brand was sold to PSA and GM appear to have pulled outs themselves.

Holden wasn't in the GM package that PSA bought - separately, GM have closed Holden in Australia & New Zealand - the Walkinshaw-owned HSV converts Chevrolet Camaro and one of the big GM SUVs to RHD but they're eye-wateringly expensive.

Jeep does quite well in Australia. Fiat are on sale but have very low sales. Even the Italians would not buy them. Chrysler was on sale for a while but I have not seen any new ones for years now. Peugeot sells in Australia but has very low volumes. VAG are the only Europeans to do any volume of business in Australia.
