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

The platforms embody the STLA Small, STLA Medium, STLA Giant, and STLA Body, and are designed with commonality and updatability of elements 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 season, and has since began rolling out some EVs primarily based on the platform outdoors the U.S. The automaker final week supplied particulars on the STLA Giant platform which can underpin its first automobiles later this yr.

The STLA Giant is designed for D and E section automobiles, which correspond to bigger compact and midsize automobiles 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 automobiles might be 201.8 inches. Rugged off-road automobiles may also be supported, because of the platform’s help for floor clearances as excessive as 11.3 inches and tire diameters of virtually 33 inches.

Stellantis confirmed there might be eight automobiles primarily based on the STLA Giant platform launched from 2024 to 2026. These will cowl the manufacturers Alfa Romeo, Chrysler, Dodge, Jeep, and Maserati. A few of the identified automobiles embody 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 might 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 characteristic 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 to 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, embody 0-62 mph instances 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 could 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 automobiles, will supply a alternative between and fuel and electrical energy.

Do not depend on a V-8 being supplied, a minimum of 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 can outperform any of the prevailing Hellcat V-8s.
