Stellantis has unveiled the new STLA Frame platform – a BEV-native multi-energy platform engineered for full-size body-on-frame pickup trucks and SUVs. The platform is designed to deliver an electric range of up to 1,100km in range-extended electric vehicles (REEV) and 800km in BEVs.
It has a maximum towing capacity of 6,350kg and a payload rating of 1,224kg. Additionally, the platform supports water wading up to 610mm, making it ready for challenging environments.
Set to underpin Stellantis full-size pickup trucks, light commercial vehicles and SUVs, the platform will initially be offered with a propulsion line-up. It can also accommodate internal combustion, hybrid and hydrogen propulsion systems in the future.
The REEV system combines a battery, front and rear electric drive modules (EDMs), onboard generator and internal combustion engine, enabling drivers to haul or tow heavy loads over extended distances without sacrificing range. With no direct link from the engine to the wheels, the generator powers the EDMs to propel the vehicle, and recharges the battery as needed, ensuring extended range while benefitting from the torque of the electric engines.
The platform is built from advanced, high-strength steel, delivering improved durability and rigidity with less weight. The widened center section houses the battery pack, with reinforced frame rails to protect the battery in the event of a side impact. A full-length belly pan reduces aerodynamic drag to help maximize driving range.
It can also accommodate liquid-cooled battery packs ranging from 159 to more than 200kWh. Stellantis designed and assembled front and rear EDMs, rated up to 250kW, to deliver all-wheel-drive capability and propel a vehicle from 0 to 96km/h in 4.4 seconds. Flexible suspension designs, including air suspension, offer an optimized ride for diverse driving conditions and loading scenarios.
In BEV configurations, the platform supports 800V DC fast charging up to 350kW, which can add 160km of range in just 10 minutes; REEVs can achieve up to 80km in 10 minutes with 400V DC fast charging at up to 175kW.
