The deal will cost PSA - the owners of Peugeot and Citroen car brands - €1.8bn ($1.9bn with GM also having to pick up some $4-4.5bn worth pension and other business-related charges.
In return, GM will hand over it's loss-making Opel operations, as well as the UK Vauxhall brand, making PSA the second largest auto-maker in Europe.
The consolidation is estimated to deliver savings in the region of €1.7bn by 2026 but, more importantly, will provide PSA with significant scale in a highly competitive marketplace. It will also bring additional expertise in electric and fuel-cell technologies.
According to reports, GM's Opel brand had lost a total of €9bn since 2009. However, PSA is confident that incorporating the GM brands with its own marques will provide a profitable turnaround in the longer-term; PSA itself having been subject to a French Government and Chinese investment bail-out in 2014.
With Britain voting to leave the EU (Brexit there is considerable concern that PSA will shut down the UK-based Vauxhall operations in Luton and Ellesmere Port near Liverpool. However, PSA Chief Executive Carlos Tavares re-stated earlier commitments made with GM that both plants would be safe until at least 2020.
The US manufacturer will retain a presence in Europe with small volume Chevrolet sales.
