BUTJust because you consider them to be doesn't make it true.
The prolonged life of the Charger, Challenger, and 300 has everything to do with the previous FCA management and nothing to do with Stellantis or Opel. Hence why even have this thread - Chrysler has finally been given a budget so they can actually produce new products.
Cars have become enormously more complicated than before. I am thankfully Stellantis has enough sense to not rush some half-baked vehicle to the market just so it can lose money. The 4-6 year development timeline for brand new cars has been the norm for decades. You could make an argument for rebranding DS cars and bringing them over here as Chryslers but it's clear they're trying to do the brand reboot correctly from the start utilizing the latest technology.
Now we have computers, sophisticated computer software and better educated, knowledgeable, skilled, imaginative engineers, designers tool designers, modern machining centers, and yet, WHERE ARE THE NEW VEHICLES ????
