STLA Giant EV platform set for 8 automobiles, helps fuel engines


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.

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.
