I have to say I agree with Bill Burke and the statement of the STLA Large platform being a solid choice for Stellantis going forward. While I mentioned above about a GT car having a hemi. Realistically, a bare basic 420hp Hurricane RWD car makes more sense as an entry-level GT car than the 5.7L. I still stand firm on my thinking that no matter what powers the GT trim package, There needs to be options and packages for that car and Direct Connection still needs to be heavily involved with that car as well.
I Also have to agree with another aspect of Bill's statement about a smaller, more nimble coupe. From 2006 till now, the Charger has solidified itself as the ultimate American Muscle sedan and to be honest, even with this new powertrains, both Hurricane and EV, it still holds that title. I worry about how well a small coupe would sell in this market as affordable coupes are honestly dwindling away from the world as we know it. Personally, I think an STLA Large platform return of the Dodge Dart, made to be about the side of a AMG GT 4-door coupe, with four doors, a fastback/liftback design just like the AMG with styling taken from the 71-77 Dart would be about the best way for Dodge to bring out a smaller, more nimble "coupe." I would also like to see Dodge bring out a Wagon on the STLA Large platform like the Coronet Wagon of the late '60's and early '70's. Doing that, plus having the Durango move to the STLA Large platform and bringing out a Dodge Grand Caravan and an off-road/all-terrain focused Ramcharger with Rebel & RHO type packages wouldn't actually be a bad idea as it would help to fill out the Dodge lineup and bring closure to the Chrysler brand. Another thing I really wanted was for Jeep to utilize this platform with the Cherokee & Grand Cherokee and bring back modern versions of the SJ Jeeps from the late 70's and early '80's with iconic Inline-6 power. Scrap the Recon completely and just have the two SJ vehicles on the STLA: Large platform and then move the FSJ vehicles to the STLA:Frame platform. STLA Frame vehicles under the Jeep brand should first include a Wrangler & a Gladiator, both with Hurricane-6 power to wipe up the ground with the Ranger and Bronco Raptor. That should have been a main priority years ago and it needs to be one right now. Both need to be seriously improved on the inside, while still keeping their classic Jeep styling or even moving to the YJ styling with the squared headlamps (almost like the Recon). The Wagoneer and Grand Wagoneer need to be on this same platform and hearken back to the SJ days as well. They should be smaller than what they are now, about the size of a Gladiator but in SUV form and the inside should have that classic rugged luxury that's not overboard but still incredibly comfortable. It should be a vehicle made for vagabonds full of wanderlust. Something that can withstand traveling roads like Route 66, camping in Yellowstone, rambling through wooded trails and fording creeks to get to remote campsites of peace away from the hustle and bustle of life. Jeep also needs a 1500-series pickup called the Honcho that takes over for the Ram RHO and Rebel with hurricane-6 powertrains seeing that Jeep is the off-road brand.
This leaves the Ram brand the room to have all of the Hemi-powered trucks it wants. Granted there should be hurricane powered trucks as well but the freedom to have the Hemi trucks is always a welcome thing. Ram trucks could also help shut the door on Chrysler because Ram trucks are luxury vehicles. Give a Ram 1500 a few packages such as Citadel, Limited, Laramie Longhorn, and Tungsten and there's no need for Chrysler. Especially if those trim levels can be had with SRT packages. Let Stellantis bring out vehicles like that along with the midsize pickup and a few other things. With that, there is no need for Chrysler because the luxury is in Ram and somewhat in Jeep.
If the Stellantis is dead set on four distinctive brands, Bring back Plymouth! All stripped down (but still decently appointed) version of the Dodge Mopars including a Trailduster SUV (Ramcharger) a Plymouth Roadrunner (Charger 4-door), a Plymouth Duster (Dart) a Plymouth Aspen (Durango) and lastly a Plymouth Satellite wagon (Coronet). All of them 4WD, all off them 420hp Hurricane powered, rear wheel drive and just the bare basic minimum and that's it. This is what an ideal lineup could look like for the brand.
