That would defeat the point of what they are doing. Dodge is known for taking every part of out the parts bin and creating all they can with them. They will wring every last cent out of their supply chain and manufacturing process before they are done.
They keep repackaging these cars with add on parts to make them look like they are new and improved, but they are just masking an aged out chassis and body to sell out the last of their parts stock. Once their supplies has dried up, they will retool and release the next big charger/challenger. You have to admit, their tactics are working.
I know Dodge is trying to attract buyers with repackaging what they have with new cosmetic changes. Doing it as cheaply as possible.
I doubt they are the same parts. The body shape is different so I am sure they are new items specific to the Charger. So that means new tooling and production. But again, these stupid flairs are a lot cheaper than tooling new fenders and quarter panels for a proper widebody. Plus the wheels and spring rates change. They are putting in the least amount of money in to maximize the return. They will sell plenty of these. Will they attract new buyers or have existing buyers trading in their old chargers to buy this one? It would be interesting to see those stats.
And you know their advertising is going to be on point.
As far as a new chassis, last time I asked my Dodge buddies, as well as tcg, no one seemed to know if they were really working on a new chassis/platform for the Charger or Challenger. So these redesigns might be all buyers get for years to come yet.
