They haven't lied about anything, believing rumor to be true is on the listener, and there is a development gate system. It actually looks like a funnel. That doesn't make it lie it just means it doesn't get approved for implementation. Actually, typically there 5 major gates and project fall out at any of them, doesn't mean they didn't exist, just means it didn't make it through.
Discounting the LX Charger and Challenger constant development means someone is woefully ignorant or purposefully negative. There is has been a powertrain upgrade every single year and this years model is better than the last, which was better than the last. People love and outperform everything in there class if there is class left because most jump off that sinking ship. 300 is dead, dead as it less than 2 sales per dealer, dead when the Continental flopped.
Reality is there is one USA major consumer brand and that is CDJR... that has multiple sub-brands Jeep, Wrangler, Wagoneer, RAM, RAM industrial, Dodge, and Chrysler. The distinction between Sub-brands and Models at this point is very small. Dodge is fine is popular with a young demographic. Will get a new model before the end of the year, and several distinct models on the new STLA Large platform. 300 will be dumped but the Minivan will switch to that platform and will get a BEV Chrysler will survive if only as a place to put stuff that doesn't fit the other Sub-brands.
Billions are being spent on redoing the Plants and more will be spent. They tried like hell to find a way to run the next gen down Brampton and the plant is too Old and was designed to make narrow Renaults.
Anyone with the slightest bases of knowledge knows you can't run an entirely new platform down a existing line without at least modifying carriers, it was going to end up being is own overly deviant platform and got shelved but there was never any rush because the models well loved and still selling strong in the marketplace.
If one doesn't like the offering currently and has to have something entirely new for NEWS sake, there is always the fake purse Koreans.
