► Details on Stellantis’ STLA platforms

► More production details of Large revealed

Automotive mega-group Stellantis is in the process of rolling out its wave of new ‘EV native’ STLA platforms across all of its major brands. The four STLA platforms (Small, Medium, Large and Frame) are designed to unify all its brands under a set of architectures based on size.

The latest to launch is STLA Large, set to start being deployed in cars launching in 2024. Stellantis says Large will be used for upcoming ‘D and E-segment’ cars by Alfa Romeo, Chrysler, Dodge, Jeep and Maserati – and one of the first cars to deploy the platform will be Jeep’s Wagoneer S SUV. In fact, eight car launches using STLA Large will happen between now and 2026.

STLA Large is designed to be ultra-flexible, offering both 400- and 800-volt architectures, and has been designed to cater to high-performance cars as well as properly capable off-roaders. Front-, rear- and all-wheel drive configurations are possible using Stellantis’ own ‘EDM’ electric motors.

As for power and performance, this is where Stellantis seems to be hitting a home run. Battery sizes of between 85 and 118kWh are possible, with up to 500 miles of range claimed for the sleekest and lowest saloons that will use STLA Large (like the upcoming replacement for the Alfa Romeo Giulia expected from 2025).

On top of that, Stellantis says cars running on STLA Large could sprint to 62mph in as little as two seconds, and points out that the most potent cars running on STLA Large ‘will outperform any of the existing Hellcat V8s.’ And, as the platform is described as ‘EV native,’ Stellantis says combustion and hybrid powertrains can be deployed for certain markets that are slower to take up EVs.

Having an 800-volt architecture as an option also allows cars running STLA Large to collect 4.5kWh of battery charge per minute.

The four physical platforms are named Small, Medium, Large and Frame.

STLA Small is arguably a heavy revision of the PSA-derived e-CMP platform, and will benefit all brands that have city cars and superminis in their portfolios. This platform allows for battery capacities between 37 and
