More or less. I believe Challenger is a derivative of the Chrysler LX platform. Which was the Charger, Magnum, and 300 initially. LX has components from W211 and W220 from there at the time parent, Daimler-Benz.
So yes, the 2023 Challenger and Charger are based on what is probably the oldest architecture in the automotive business.
that is wild. mercedes and dodge parted ways looong ago so did dodge just take over manufacture of the various components they use or is mercedes still using them elsewhere also, thus able to be a 3rd party supplier for stellantwhatever?
