Sizzling on the heels of a Jeep Wagoneer S teaser and photographs of the prototype next-generation Dodge Charger (or Challenger), comes a reveal and particulars of what is going to doubtless underpin each of them: the STLA Massive platform. It is considered one of a number of Stellantis versatile architectures that would be the foundation of its upcoming electrical vehicles, and apparently inside combustion ones, too.
Stellantis says the STLA Massive platform will likely be for D- and E-segment vehicles, crossovers and SUVs. In different phrases, it is going to be for midsize and enormous automobiles. For reference, lengths supported will likely be from 187.6 to 201.8 inches, and width will vary from 74.7 to 79.9 inches. Will probably be extremely versatile, too, with Stellantis claiming important quantities of adjustability in overhangs, wheelbase, suspension placement and powertrain association.
The powertrain flexibility is kind of spectacular. Entrance-, rear- and all-wheel-drive layouts will likely be supported. Single- and dual-motor layouts will likely be on provide. Inner combustion will likely be obtainable, too, both by itself or as a hybrid. Apparently engines will be fitted both longitudinally or transversely, too.
Battery packs with between 85 and 118 kWh of capability will likely be provided, with Stellantis claiming that sedan-style automobiles might have a spread of as much as 500 miles. The packs can even be obtainable in 400- and 800-volt designs. Stellantis famous additionally that the platform can “simply settle for future vitality storage applied sciences once they attain manufacturing readiness.” This appears to trace that the corporate is totally different battery chemistries and perhaps even solid-state batteries that might be added extra simply sooner or later. Moreover, the platform is designed to deal with spectacular output. Stellantis says that some fashions on the platform could have 0-to-62 mph instances within the 2-second vary. Restricted-slip differentials for improved energy supply and wheel-end disconnects for diminished mechanical drag are additionally on the desk for this platform.
All of those particulars match nicely with the data beforehand given for the idea Dodge Charger Daytona Banshee and Jeep Wagoneer S. The previous was previewed with each battery voltage architectures and a variety of electrical powertrains with between 456 and 670 horsepower relying on specification and upgrades. And that is only for the 400-volt system; the 800-volt possibility wasn’t detailed. We have additionally seen photographs of the Charger chassis seemingly with provisions for gasoline engines, doubtless variations of the Hurricane I6. The high-performance Wagoneer S additionally suits the platform and its anticipated 600 horsepower. Stellantis famous this platform can even assist as much as 11.3 inches of floor clearance and tires as much as 32.6 inches in diameter, each necessary for serving to the Jeep keep some off-road credibility. We’re curious if the powertrain flexibility of the STLA Massive implies that Jeep can even provide a hybrid or plain internal-combustion model of the Wagoneer S.
The launch timing for the STLA Massive platform additionally suits that of the Charger and Wagoneer S. Each are slated to launch this yr, and Stellantis stated that the primary Massive platform automobiles will likely be this yr from Dodge and Jeep. However different fashions are coming. Alfa Romeo, Chrysler and Maserati can even have Massive platform vehicles, with eight automobiles throughout the Stellantis line launching by 2026.
