Stellantis Reveals STLA Frame Platform Delivers Record 690-Mile Range for Trucks
Stellantis officially unveiled its highly anticipated STLA Frame platform this week, a new architecture designed specifically to underpin full-size body-on-frame pickup trucks and SUVs for the Ram and Jeep brands. This structure represents the third major release in the automaker’s “Dare Forward 2030” strategic plan, following the STLA Medium and STLA Large platforms. The company engineered the chassis to support multiple propulsion systems, including battery-electric (BEV), hydrogen, internal combustion, and a range-extended electric vehicle (REEV) configuration that addresses towing and range anxiety concerns.
The technical specifications released by the automaker indicate a significant leap in capability for electrified trucks. In its REEV configuration, the platform delivers a manufacturer-estimated range of up to 690 miles (1,100 kilometers), while the pure BEV version targets 500 miles (800 kilometers). The architecture utilizes liquid-cooled battery packs ranging from 159 kWh to over 200 kWh, enabling these substantial distance figures. Critically for the truck segment, the platform supports a maximum towing capacity of 14,000 pounds (6,350 kg) and a payload rating of 2,700 pounds (1,224 kg).
Performance metrics suggest that efficiency will not come at the cost of speed or power. Vehicles built on the STLA Frame can achieve a 0-60 mph acceleration time of just 4.4 seconds, driven by dual electric drive modules (EDMs) that provide standard all-wheel-drive capability. The system supports both 400-volt and 800-volt architectures, allowing for DC fast charging up to 350 kW. According to Stellantis, this charging speed can add 100 miles of range in approximately 10 minutes, a crucial factor for commercial and long-distance operators.
Stellantis CEO Carlos Tavares emphasized the platform’s versatility as a direct response to consumer hesitation regarding electric truck adoption. The architecture’s widened center section protects the battery pack with reinforced frame rails, while a full-length belly pan reduces aerodynamic drag to maximize efficiency. The design also accommodates future technologies, ensuring that upcoming Ram and Jeep models remain adaptable as infrastructure evolves.
The introduction of the STLA Frame intensifies the competition in the electric truck market, challenging established rivals like the Ford F-150 Lightning and Chevrolet Silverado EV. By offering a range-extended option that exceeds the 600-mile mark, Stellantis aims to capture buyers who tow heavy loads over long distances—a demographic that has largely resisted pure electric transitions due to range degradation. Production vehicles utilizing this new architecture are expected to arrive in dealerships shortly, marking a pivotal shift in the heavy-duty automotive sector.
