Stellantis, the world’s fourth-largest automaker, has revealed its latest innovation in electric vehicle technology: the STLA Large platform. This platform is designed to underpin a wide range of vehicles in the D and E segments, from sedans to SUVs, and offer segment-leading capabilities in range, performance, charging efficiency, and off-road driving.
The STLA Large platform is part of Stellantis’ ambitious plan to electrify its entire portfolio of 14 brands by 2030, as announced on EV Day 2021. The company aims to launch 21 battery electric vehicles (BEVs) and 10 plug-in hybrid electric vehicles (PHEVs) by 2025, and achieve a BEV+PHEV mix of 70% in Europe and 40% in the US by 2030.
What makes the STLA Large platform unique?
The STLA Large platform is a BEV-native platform. It is designed from the ground up for electric propulsion, unlike some platforms adapted from existing internal combustion engine (ICE) vehicles. This gives the platform several advantages, such as:
- Optimized packaging: The platform can accommodate a large battery pack of up to 118 kWh, which is integrated into the floor of the vehicle, creating a low center of gravity and freeing up space for passengers and cargo. Depending on the vehicle type and performance level, the platform can also fit various electric motors, ranging from 150 kW to 330 kW.
- High flexibility: The platform can support 400-volt and 800-volt BEV architectures, allowing for different charging speed and power output levels. The platform can also underpin different vehicle types, from cars to crossovers to SUVs, and different brands, from Dodge to Jeep to Maserati. The platform can be customized to suit the specific identity and features of each brand and model while maintaining a common set of components and processes that ensure quality and efficiency.
- Segment-leading capabilities: The platform enables several segment-leading capabilities, such as:
- Range: The platform targets an overall range of 800 km/500 miles for sedans, which is comparable to some of the best-performing BEVs in the market, such as the Tesla Model S and the Lucid Air. The platform is also engineered to easily accept future energy storage technologies when they reach production readiness, such as solid-state batteries, which could offer higher energy density and lower cost than current lithium-ion batteries.
- Performance: The platform holds the potential to deliver acceleration of 0-100 km/h (62 mph) in the 2-second range, which is faster than most ICE sports cars and supercars. The platform also enables high-performance vehicle dynamics, such as torque vectoring, adaptive suspension, and four-wheel steering, which enhance the handling and stability of the vehicle.
- Charging efficiency: The platform can achieve a charging efficiency of 4.5 kWh per minute, which means that it can add up to 200 km/125 miles of range in just 10 minutes of charging, depending on the vehicle type and the charger type. The platform can support both AC and DC charging and is compatible with various charging standards and networks, such as CCS, CHAdeMO, and Tesla Supercharger.
- Off-road driving: The platform can enable Trail Rated off-road driving, a Jeep brand trademark. The platform can provide features such as high ground clearance, skid plates, tow hooks, locking differentials, low-range gearing, and selectable drive modes, which allow the vehicle to tackle various terrains and conditions, such as rocks, sand, mud, snow, and water.
