Stellantis has unveiled the “STLA Large”, a flexible BEV platform that will serve as the foundation for a wide range of upcoming electric vehicles.
First to launch will be Dodge and Jeep® brands, followed by others including Alfa Romeo, Chrysler, and Maserati. Eight vehicles are planned to be launched from 2024-2026.
STLA Large is designed as a native BEV platform with the option of 400-volt and 800-volt electric architectures. Three-in-one electric drive modules (EDMs) that incorporate the motor, power inverter, and gear reduction can be configured in front-wheel-drive, rear-wheel-drive, and all-wheel-drive layouts. The power inverter uses silicon carbide semiconductor technology to minimize power losses. Propulsion system performance can be upgraded during the vehicle’s lifespan via over-the-air software updates.
The platform offers several capabilities including embedded energy, charging efficiency, high-performance vehicle dynamics, and trail-rated off-road driving.
The platform’s flexibility enables engineers and designers to adjust the wheelbase, overall length, overall width and height, and ground clearance. A variety of suspension modules and powertrain cradles can be employed to suit vehicle-specific performance objectives that include ride, handling, and comfort. Engineers can adjust key dimensions, such as the front spindle to the driver’s foot, the front and rear overhang, or the passenger compartment floor, to fine-tune vehicle capabilities and performance.
STLA Large is one of four global BEV platforms, outlined on Stellantis’ EV Day 2021, that underpin the company’s future products and are key to achieving the targets of the Stellantis Dare Forward 2030 strategic plan. It is the second platform to be revealed following the release of STLA Medium in July 2023.
Stellantis is investing more than €50 billion over the next decade in electrification to deliver on the targets of reaching a 100% passenger car BEV sales mix in Europe and 50% passenger car and light-duty truck BEV sales mix in the United States by 2030. To achieve these sales targets, the company is securing approximately 400 GWh of battery capacity, including support from six battery manufacturing plants in North America and Europe. Stellantis plans to have 48 BEVs on the market by 2024 and is on track to become a carbon net zero corporation by 2038, all scopes included, with single-digit percentage compensation of remaining emissions.
