from what I've read if it ever does happen it will be under the SRT Performance Brand not Dodge,
Possibly so the Plymouth purists, won't complain about the Plymouth `Cuda marquee/badging on a Dodge model car...
IF & that's a big IF, it's actually ever produced, like the GTX or Roadrunner also,
it'll no doubt probably be on a LX platform dressed up, that they already use for 300's & Challengers or Chargers...
I don't or wouldn't think anyway, that they aren't going to redesign a whole new platform/model,
just for a specialty car or show concept one off... use one floor-pan, firewall & suspension/drive train etc. for all...
it's all conjecture so far thou...
it's been in the works for a while on the Detroit, Chicago & LA Manufacturers Auto-show circuit
not sure it or they will ever get built thou...
a Hellcat Hemi `cuda/Barracuda, or GTX or Road Runner would be cool as hell,
my $0.02 cents
