Stellantis (NYSE: STLA)* today unveiled a large, battery electric vehicle (BEV) platform that is the foundation for a wide range of upcoming vehicles for global markets in the larger profitable D and E segments. The so-called STLA platform enables what could be segment-leading capabilities including embedded energy, charging efficiency, high-performance vehicle dynamics and Trail Rated (Jeep) off-road driving. Full-size vehicles based on STLA Large architecture are projected to be at the center of customer demand in key global markets.
“Our goals for our STLA platforms are ambitious but this is what our customers need from us today,” said Stellantis CEO Carlos Tavares. “Creating a family of vehicles from a well-engineered set of components that is flexible enough to cover multiple vehicle types and propulsions, over-performing any of our current products, will address each of our iconic brands’ customers. The flexibility and agility of this platform is its hallmark and will be a driving force for our success in the shift to electrification in North America.”

STLA will be used first in the truck dominated North American market on Dodge and Jeep® brands, followed by other brands including Alfa Romeo, Chrysler and Maserati. There will be eight BEVs launched from 2024-2026. (AutoInformed: Dare Forward 2030 – Stellantis Survival Plan Unveiled )
STLA Large is one of four global BEV platforms, outlined on EV Day 2021, that underpin the Stellantis’ future products. They are key to achieving the bold targets of the Stellantis Dare Forward 2030 strategic plan. It is the second platform to be revealed following the release of the STLA Medium in July 2023. STLA Large will be installed in several plants in Europe and North America and available in multi-energy variants, including hybrid and internal combustion. Stellantis brands will adapt STLA Large vehicles to the needs and desires of their customers, ranging from family oriented to high performance to highly capable off-road 4×4 to luxury.
The platform’s inherent flexibility enables engineers and designers to adjust the wheelbase, overall length, overall width and height, and ground clearance, Stellantis said and has said 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 foot, the front and rear overhang, or the passenger compartment floor, to fine-tune vehicle capabilities and performance.
Using advanced high-strength materials, the platform is optimized for weight and rigidity to enable best-in-class performance across the spectrum of vehicle types. Components within the platform are packaged to maximize usable interior space and storage. Key comfort and performance components, such as the cabin heating/cooling system, steering, braking assist and propulsion are designed to minimize energy consumption to enhance driving range.
The flexibility includes the unibody platform’s propulsion systems. STLA Large is designed and engineered as a native BEV platform with the option of 400-volt and 800-volt electric architectures. Three-in-one electric drive modules (EDMs) that combine 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.
Based on specific vehicle objectives, STLA Large accepts drivetrain improvements such as limited slip differentials or wheel end disconnects that can increase performance or reduce mechanical drag to increase efficiency and range. Overall, the STLA Large platform has the potential to carry extreme power that will outperform any of the existing Hellcat V8s.
The STLA platform initially includes battery pack options with energy ratings between 85 and 118 kilowatt hours (kWh). STLA Large targets an overall range of 800 km/500 miles for sedans and is engineered to accept future energy storage technologies when they reach production readiness.
The initial generation of propulsion components holds the potential to deliver acceleration of 0-100 km/h (62 mph) in the 2-second range. Fast charging will add up to 4.5 kWh per minute to the 800-volt battery pack.
STLA Large also supports hybrid and internal combustion propulsion systems without compromising key vehicle capabilities, it’s said. The flexibility provides a bridge for customers around the world during the transition to electric propulsion and the development of a robust and widely available charging network. Design flexibility includes transverse and longitudinal engine mounting configurations, supporting FWD/RWD/AWD drivetrains.
Key STLA Large Metrics
- Overall length range: 187.6-201.8 inches (4,764-5,126 mm)
- Overall width range: 74.7-79.9 inches (1,897-2,030 mm)
- Wheelbase range: 113.0-121.1 inches (2,870-3,075 mm)
- Ground clearance range: 5.5-11.3 inches (140-288 mm)
- Maximum tire diameter: 32.6 inches (858 mm)
The four Stellantis global BEV platforms – Small, Medium, Large and Frame – are designed and engineered for extended life cycles via the interchangeability of battery cell chemistry, EDMs, power inverters and software control. The STLA Large platform supports Stellantis’ next-generation electrical and software-defined vehicle technologies – STLA Brain, STLA SmartCockpit and STLA AutoDrive.
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, Stellantis 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.
