Stellantis unveils STLA Large – EV-first platform that also supports ICE, hybrid, hydrogen and REEV tech
Stellantis has unveiled the SLTA Frame, which is one of several platforms announced by the company that will underpin future models. As stated in a release, the STLA Frame platform is versatile in that it is both scalable and able to support a wide range of powertrains, including pure internal combustion (ICE), hybrid (HEV), hydrogen, battery electric (BEV) and range-extended electric vehicle (REEV) technologies.
The company claims the EV-first platform will deliver class-leading range figures as high as 1,100 km with the REEV and 800 km for the BEV. Such vehicles are said to accommodate liquid-cooled battery packs with energy densities ranging from 159 to over 200 kWh.
BEVs will come with an 800V electrical architecture to enable DC fast charging at up to 350 kW, which can add 160 km of range in just 10 minutes, while REEVs get a 400V system for a peak charging capacity of 175 kW to gain 80 km in 10 minutes. Bi-directional charging will also be part of the STLA Frame’s feature set, allowing the vehicle’s battery to charge another EV, power a home or feed electricity back to the grid.
Electric drive modules (EDMs) developed for the platform are rated for up to 340 PS (335 hp or 250 kW), with two able to be equipped to provide all-wheel drive. Depending on the configuration, vehicles built on the platform can get from 0-96 km/h in 4.4 seconds. Stellantis will also offer a variety of suspension designs, including air suspension, for diverse driving conditions and loading scenarios.
Loading was mentioned because the STLA Frame is intended to underpin Stellantis’ full-size pick-up trucks, light commercial vehicles as well as large SUVs. Vehicles of these types have specific requirements, which is why the platform will enable a maximum towing capacity of 6,350 kg and a payload rating of 1,224 kg. Additionally, the platform supports water fording up to 610 mm.
“Like STLA Medium and STLA Large, STLA Frame combines an unprecedented range with new levels of capability and performance to offer best-in-class range, payload and towing for our customers who need reliable and powerful trucks and SUVs, to haul their families or power their businesses,” said Stellantis CEO Carlos Tavares.
“With full EV and extended-range EV tech coming soon, we’re bringing ‘no compromise’ solutions to buyers who may be hesitant on trying their first electric vehicle. We’re proud of this engineering marvel and look forward to seeing it come to life in our upcoming product blitz on Jeep and Ram,” he added.
