Stellantis plans 4 extremely modular platforms to underpin electrical autos throughout its numerous vary of manufacturers, together with many to be offered within the U.S.

The platforms embrace the STLA Small, STLA Medium, STLA Giant, and STLA Body, and are designed with commonality and updatability of components in thoughts, particularly with regards to the battery and electrical drive models (sometimes the electrical motor, transmission, and inverter).

Stellantis supplied particulars on the STLA Medium platform final summer time, and has since began rolling out some EVs primarily based on the platform exterior the U.S. The automaker final week supplied particulars on the STLA Giant platform which can underpin its first autos later this yr.

The STLA Giant is designed for D and E phase autos, which correspond to bigger compact and midsize autos within the U.S. For full-size electrical vans and SUVs, Stellantis will use the STLA Body platform. Stellantis mentioned the utmost size for STLA Giant-based autos can be 201.8 inches. Rugged off-road autos can even be supported, because of the platform’s help for floor clearances as excessive as 11.3 inches and tire diameters of just about 33 inches.

Stellantis confirmed there can be eight autos primarily based on the STLA Giant platform launched from 2024 to 2026. These will cowl the manufacturers Alfa Romeo, Chrysler, Dodge, Jeep, and Maserati. Among the identified autos embrace the Dodge Challenger/Charger successor due late this yr, in addition to Alfa Romeo’s replacements for the Giulia and Stelvio. Jeep’s upcoming Wagoneer S and Recon SUVs will doubtless even be primarily based on the STLA Giant platform.

There can be each 400- and 800-volt variations, the latter enabling speedy charging utilizing DC fast-chargers (as much as 4.5 kwh per minute). And to spice up effectivity, dual-motor all-wheel-drive configurations may have a disconnect function to cut back mechanical drag. The ability inverters additionally use silicon carbide semiconductor expertise that Stellantis mentioned helps decrease energy losses.

Preliminary battery sizes will vary between 85 and 118 kwh, with Stellantis estimating that some fashions will be capable of obtain as much as 500 miles of vary, doubtless measured on the WLTP cycle used abroad, a extra lenient cycle than what the EPA makes use of.

Different efficiency estimates, relying on the automobile and its explicit configuration, embrace 0-62 mph occasions within the two-second vary.

The platform additionally options Stellantis’ new electrical structure, often called STLA Mind, which permits software program updates to be simply carried out.

Although the platform is designed with EVs in thoughts, it may possibly additionally help fuel and hybrid powertrains, in each transverse and longitudinal configurations. This strengthens rumors the upcoming Charger successor, in addition to different STLA Giant-based autos, will supply a alternative between and fuel and electrical energy.

Do not depend on a V-8 being supplied, not less than from the manufacturing unit. Stellantis is phasing out the V-8 throughout its lineup. Probably the most highly effective fuel engine will doubtless be Stellantis’ twin-turbocharged 3.0-liter inline-6 often called the Hurricane, which can be paired with a hybrid system to take energy ranges past that of the present supercharged 6.2-liter V-8 often called the Hellcat.

Stellantis mentioned the STLA Giant platform has the potential to pack “excessive energy” that may outperform any of the present Hellcat V-8s.
