Stellantis, the world’s fourth-largest automaker, has recently unveiled its new STLA Large platform, a BEV-native architecture that will underpin a wide range of upcoming vehicles for global markets in the D and E segments. The platform boasts several segment-leading capabilities such as embedded energy, charging efficiency, high-performance vehicle dynamics and Trail Rated off-road driving. It also offers the ultimate flexibility to cover multiple vehicle types and propulsions, from cars to crossovers to SUVs and from 400-volt to 800-volt BEV architectures.
The STLA Large platform is part of Stellantis’ ambitious electrification strategy, which aims to achieve 40% of its sales in the U.S. and Europe from low-emission vehicles by 2030. The company plans to launch eight vehicles based on the STLA Large platform across five brands from 2024-2026. The first ones to debut will be from Dodge and Jeep, followed by Alfa Romeo, Chrysler and Maserati. The platform is designed to easily accept future energy storage technologies when they reach production readiness.
What Makes the STLA Large Platform So Special?
The STLA Large platform is engineered with unparalleled technology flexibility that enables greater levels of vehicle diversity and top-rank quality and customer satisfaction from a base set of componentry, along with robust and cost-efficient manufacturing processes that can be duplicated in multiple assembly plants. The platform also enables several segment-leading capabilities that will give customers the electric propulsion benefits of instant torque response combined with zero emissions. Some of these capabilities are:
- Embedded energy: The platform targets an overall range of 800 km/500 miles for sedans and 725 km/450 miles for SUVs, thanks to its 118 kWh battery pack that can be configured in different shapes and sizes to fit various vehicle types. The battery pack also features a thermal management system that optimizes the performance and durability of the cells.
- Charging efficiency: The platform can support both 400-volt and 800-volt BEV architectures, depending on the vehicle type and market demand. The 800-volt architecture allows for faster charging times, up to 4.5 kWh per minute, which translates to 32 km/20 miles of range in just one minute of charging. The platform also supports bidirectional charging, which means the vehicle can supply electricity back to the grid or to other devices.
- High-performance: The platform delivers impressive performance figures, such as acceleration of 0-100 km/h (62 mph) in the 2-second range, top speed of over 300 km/h (186 mph), and power output of up to 330 kW (443 hp) per axle. The platform also features a torque vectoring system that enhances the handling and stability of the vehicle.
- Trail Rated: The platform is capable of delivering Trail Rated off-road performance for Jeep® vehicles, thanks to its four-wheel-drive system that can provide up to 100% of torque to any wheel. The platform also offers air suspension that can adjust the ride height and damping of the vehicle, as well as skid plates, tow hooks, and water fording capabilities.
