Stellantis has pulled the drapes off its all-new STLA Massive platform that it hopes will give it the sting in the case of its greatest costliest EVs from the likes of Alfa Romeo, Maserati and Jeep.
Stated to be an evolution of the STLA Medium underpinnings that the incoming Peugeot e-3008 shall be primarily based on, the brand new STLA Massive Structure has been specifically designed for autos that measure between 4764mm and 5126mm lengthy with wheelbases that may stretch from 2870mm to 3075mm.
Though it’s been designed to be a devoted EV platform, the brand new structure can nonetheless house a petrol-electric hybrid powertrain, if wanted, whereas the extremely versatile platform can be stated to be appropriate with front-, rear- or all-wheel drive powertrains.

Initially, the battery pack will fluctuate in measurement from 85kWh to as much as 118kWh with essentially the most effectivity fashions providing the utmost 800km of vary. Anticipate greater energy packs to observe, together with differing chemistries because the tech quickly evolves.
First to make use of the brand new STLA Massive platform would be the incoming Dodge Charger Daytona muscle automotive in addition to the fashionable new Jeep Wagoneer S SUV-coupe. Each shall be impossibly fast, with the Wagoneer S set to pump out round 450kW and launch from 0-100km/h in 3.5 seconds.
The Charger EV, in the meantime, shall be even quicker and is tipped to come back with a triple-motor set-up from the Maserati GranTurismo Folgore. In that case, count on the Dodge EV to push out not less than 660kW and for it to ship a 0-100km/h sprint of round 2 seconds.
When it begins underpinning future autos, the platform will assist the Stellantis-owned model’s ship phase main effectivity, in addition to providing each 400-volt and 800-volt electrical architectures.With the extra 800-volt system, the on-board batteries shall be able to being charged at as much as 270kW.
Serving to maximise area inside, the Stellantis group that additionally owns Fiat, Peugeot, Citroen, Lancia, Chrysler, Abarth and RAM has produced a compact three-in-one electrical drive module that cleverly packages inside one casing the motor, energy inverter and transmission.
Lowering driveline losses, the inverter employs silicon carbide semiconductors. Stellantis says the brand new three-in-one electrical drive modules have been developed to be upgraded over their lifespan, producing much more energy over their life following over-the-air updates.
New chassis {hardware} developed to be appropriate with the platform embrace traction-boosted limited-slip differentials which have each a efficiency and an off-road utility.
Talking of the latter, the brand new STLA Massive structure may also spin-off the brand new Land Rover Defender-rivalling Jeep Recon.
Meaning engineers have developed and ensured the platform will present the potential wanted for the rugged 4×4 to be Path Rated-certified – Jeep’s stamp of approval that’s solely given to its most succesful off-roaders, that means it’s going to lead the EV phase for traction, floor clearance, wading, off-road articulation and basic functionality off street.
That stated, the platform’s greatest limitation is it could actually solely home tyres as much as 33-inch broad. Meaning it’s going to miss out on the biggest 37-inch rubber favoured by essentially the most excessive 4x4s. To compensate, the platform will have the ability to present between 140mm to up a really respectable 288mm floor clearance.
Extra particulars are anticipated to be launched on the newest platform with the launch of the incoming 2024 Jeep Wagoneer S and 2024 Dodge Charger Daytona.
