There is so much poor reading comprehension in today's general population. Let me quote a paragraph from the article in question.
At its core, the Battery Technology Centre stands as a testament to Stellantis’ commitment to shaping the future of transportation. Focusing on battery-electric vehicle (BEV), plug-in hybrid electric vehicle (PHEV), and hybrid electric vehicle (HEV) cells, modules, and battery packs, the centre aims to redefine the benchmarks for performance, durability, and cost-efficiency.
The above quote states that Stellantis is not selling only battery electric vehicles. They are not a company "Going all in." as Mary Barra spoke for GM. If one posts a statement of "only EVs" it will be assumed to mean BEV, because the market for hybrid vehicles is very lucrative. So one can't lump the technologies together with a general comment.
The name of this website hosting these forums is
Mopar Insiders. I only worked for third tier suppliers providing production tooling for Chrysler Corporation and its competitors. There are other people on these forums who have a much better knowledge of the inner workings than I do. What I do know from my experience is that companies which don't invest in R&D go out of business. Look at Packard which was much too late to the party with a modern V8 and is now history.
Getting back to the article this thread follows. Batteries are necessary for both hybrid and full battery electric power power. The way forward is through hybrids, but real solutions are needed for BEV. There are people wanting full battery electric, but are held back by unstable battery chemistry, lack of charging infrastructure and price concerns. Solve these problems and sales will of EVs will rise again.
