rmc523 Posted January 19 Share Posted January 19 Stellantis reveals STLA Large platform with EV and ICE support - Autoblog Quote Hot on the heels of a Jeep Wagoneer S teaser and photos of the prototype next-generation Dodge Charger (or Challenger), comes a reveal and details of what will likely underpin both of them: the STLA Large platform. It's one of multiple Stellantis flexible architectures that will be the basis of its upcoming electric cars, and apparently internal combustion ones, too. Stellantis says the STLA Large platform will be for D- and E-segment cars, crossovers and SUVs. In other words, it will be for midsize and large vehicles. For reference, lengths supported will be from 187.6 to 201.8 inches, and width will range from 74.7 to 79.9 inches. It will be highly flexible, too, with Stellantis claiming significant amounts of adjustability in overhangs, wheelbase, suspension placement and powertrain arrangement. The powertrain flexibility is quite impressive. Front-, rear- and all-wheel-drive layouts will be supported. Single- and dual-motor layouts will be on offer. Internal combustion will be available, too, either on its own or as a hybrid. Apparently engines can be fitted either longitudinally or transversely, too. Battery packs with between 85 and 118 kWh of capacity will be offered, with Stellantis claiming that sedan-style vehicles could have a range of up to 500 miles. The packs will also be available in 400- and 800-volt designs. Stellantis noted also that the platform can "easily accept future energy storage technologies when they reach production readiness." This seems to hint that the company is looking at different battery chemistries and maybe even solid-state batteries that could be added more easily in the future. Furthermore, the platform is designed to handle impressive output. Stellantis says that some models on the platform will have 0-to-62 mph times in the 2-second range. Limited-slip differentials for improved power delivery and wheel-end disconnects for reduced mechanical drag are also on the table for this platform. 1 Quote Link to comment Share on other sites More sharing options...
silvrsvt Posted January 22 Share Posted January 22 This really makes me wonder if Stellantis is going to double down on their EV/Hybrid vs going pure hybrid. Seems like they are going to compromise their EV products by making them overly complex to be able to still take an ICE powertrain. Quote Link to comment Share on other sites More sharing options...

We’ll see how it works out. 1 Quote Link to comment Share on other sites More sharing options...
Dequindre Posted January 24 Share Posted January 24 I'm interested to see how this platform works out for them. The flexibility of ICE, hybrid, and EV seems like a smart idea that will allow them to adapt to consumer preferences. Quote Link to comment Share on other sites More sharing options...

Jack of all trades, master of none. 2 Quote Link to comment Share on other sites More sharing options...

If sales of vehicles on bespoke EV platforms plateau or shrink (think Ford GE1, GM Ultium, etc.), then it was a very costly proposition to develop that platform with little in economic return. Stellantis can prevent that scenario. Quote Link to comment Share on other sites More sharing options...

And won't be as efficient energy wise vs a bespoke EV platform Easiest way to explain this is making a coupe off a sedan platform, the vast majority of the time you'll have additional weight concerns due to crash structure design that was made for a four door vs a 2 door.
