Stellantis N.V. unveiled STLA Large, its all-new, highly flexible BEV platform, which forms the basis for a wide range of upcoming vehicles in the D and E segments for global markets. The platform is equipped with segment-leading features, such as the amount of energy available on board, charging efficiency, high-performance and off-road (Trail Rated) driving dynamics. STLA Large-based full-size vehicles are focused on customer demand in key global markets and will be adopted initially in the North American market by the Dodge and Jeep® brands, followed by other brands, including Alfa Romeo, Chrysler and Maserati. Eight models will be launched in the 2024-2026 period.
Stellantis' family of four global BEV platforms - Small, Medium, Large and Frame - were conceived and engineered to extend vehicle lifecycles through interchangeability of battery cell chemistry, EDMs, power inverters and of the control software. The STLA Large platform supports Stellantis' next-generation electrical and software-defined technologies: STLA Brain, STLA SmartCockpit and STLA AutoDrive.
Stellantis is investing more than 50 billion euros over the next decade in electrification to reach the goal of 100% battery electric vehicle (BEV) sales mix in Europe and 50% BEV passenger cars and light commercial vehicles in the United States United by 2030. To achieve these sales goals, the Company is securing approximately 400 GWh of planned battery capacity, supported by six battery manufacturing facilities in North America and Europe. Stellantis plans to bring 48 BEVs to market by 2024 and is on track to become a zero-carbon company by 2038, all scopes included, with single-digit offsetting of remaining emissions.
The STLA Large platform was designed with unprecedented technological flexibility that enables a wide variety of vehicles, world-class quality and customer satisfaction, starting from a series of basic components, as well as robust and cost-efficient production, which can be replicated in different assembly plants. Upcoming products will cover an entire range of vehicles, from sedans to crossovers to SUVs, all offering customers the benefits of electric propulsion with instant torque response and zero emissions. More specific information on the products of the individual brands will be released as early as this year.
STLA Large is one of four global BEV platforms, featured on EV Day 2021, that underpin the Company's future products and are critical to achieving the ambitious goals of the Stellantis Dare Forward 2030 strategic plan. This is the second platform to be launched unveiled after the best-in-class STLA Medium, unveiled in July 2023. STLA Large will be produced in several factories in Europe and North America and multi-energy variants will be available, including hybrid and internal combustion. Stellantis' iconic brands will customize STLA Large vehicles to best meet the needs and desires of their customers, ranging from family vehicles to high-performance vehicles, from 4x4 off-road vehicles to the luxury segment.
The inherent flexibility of the platform gives engineers and designers the ability to define the wheelbase, overall length, width, and overall and ground clearances. Different suspension modules and multiple powertrain systems can be used to meet each vehicle's specific performance objectives, including ride, handling and comfort. Engineers can modulate key dimensions, such as the distance between the center of the front wheels and the driver's feet, front and rear overhangs, and the floor, to fine-tune the vehicles' capabilities and performance.
Thanks to the use of innovative high-strength materials, the platform is optimized in terms of weight and rigidity to enable best-in-class performance for all types of vehicles. Platform components are crafted to maximize space inside the vehicle and trunk. Platform components, such as the air conditioning system, steering, braking system and propulsion system, are designed to minimize energy consumption and improve driving range.
The flexibility of the unibody platform also relates to the propulsion systems. STLA Large was conceived and designed as a native BEV platform, with the ability to choose 400 and 800 volt electrical architectures. The three-in-one electric propulsion modules (EDM), incorporating the motor, power inverter and reduction gear, can be configured in a front-, rear- or all-wheel drive layout. The power inverter uses silicon carbide semiconductor technology to minimize power losses. Powertrain performance can be improved over the life of the vehicle through over-the-air software updates.
Depending on the specific objectives of each vehicle, STLA Large can be equipped with variants to the transmission system, such as limited-slip differentials or wheel decoupling, which can improve performance or reduce mechanical resistance to improve efficiency and autonomy . Overall, the STLA Large platform can unleash extreme power that will surpass any existing Hellcat V8.
In consideration of the importance of balancing autonomy and cost, the platform will initially be offered with different battery options with capacities between 85 and 118 kilowatt hours (kWh). STLA Large has an overall range of 800 km (500 miles) for sedans and is designed to easily adapt to upcoming energy storage technologies when they are ready for production.
The initial generation of propulsion components has the potential to deliver acceleration from 0 to 100 km/h (62 mph) in the order of 2 seconds. Fast charging will add up to 4.5 kWh per minute to the 800-volt battery.
STLA Large also supports hybrid and internal combustion propulsion systems without compromising the vehicle's inherent capabilities. This flexibility represents a “bridge” for customers around the world in the transition to electric propulsion with the development of a robust and widely available charging network. Design flexibility includes transverse and longitudinal engine installation configurations, supporting FWD/RWD/AWD transmissions.
