Stellantis, the automotive conglomerate, is currently introducing its new line of ‘EV native’ STLA platforms across its major brands. These four platforms, named Small, Medium, Large, and Frame, are strategically designed to provide a unified architecture for the diverse range of vehicles offered by the company.

The most recent addition to this lineup is the STLA Large platform, scheduled to debut in cars launching in 2024. This platform is set to be utilized for forthcoming ‘D and E-segment’ vehicles from Alfa Romeo, Chrysler, Dodge, Jeep, and Maserati. The Jeep Wagoneer S SUV is slated to be one of the first vehicles to adopt the STLA Large platform, with eight more car launches expected between now and 2026.

STLA Large boasts exceptional flexibility, accommodating both 400- and 800-volt architectures. It caters to a spectrum of vehicles, including high-performance cars and robust off-roaders, supporting various configurations such as front-, rear–, and all-wheel drive with Stellantis’ proprietary ‘EDM’ electric motors.

In terms of power and performance, STLA Large demonstrates impressive capabilities. It offers battery sizes ranging from 85 to 118kWh, with a claimed range of up to 500 miles for sleek and low-profile sedans like the anticipated replacement for the Alfa Romeo Giulia.

Stellantis states that vehicles on the STLA Large platform could achieve a 0-62mph acceleration in as little as two seconds, surpassing the performance of existing Hellcat V8s. Additionally, the platform, being ‘EV native,’ allows for the deployment of combustion and hybrid powertrains in markets where the adoption of EVs is slower.

The 800-volt architecture option for STLA Large enables rapid charging, collecting 4.5kWh of battery charge per minute. This feature contributes to efficient charging and underscores Stellantis’ commitment to advancing electric vehicle technology.
