Auburn Hills-based Stellantis has unveiled the STLA Frame platform, a battery electric vehicle-native, multi-energy platform engineered for full-size body-on-frame pickup trucks and SUVs.
The STLA Frame platform is designed to deliver what Stellantis states is class-leading range of up to 690 miles with range-extender electric-vehicle (REEV) technologies and 500 miles in BEV, a maximum towing capacity of 14,000 pounds and a payload rating of 2,700 pounds.
Additionally, the platform is designed to support water fording up to 24 inches.
STLA Frame vehicles will initially be offered with an “innovative” propulsion lineup, including a full BEV system and a REEV configuration. STLA Frame also can accommodate internal combustion, hybrid, and hydrogen propulsion systems in the future.
The REEV system, which combines a battery, front and rear electric drive modules (EDMs), on-board generator, and internal combustion engine, allows drivers to haul or tow heavy loads over extended distance without sacrificing range.
With no direct mechanical path from the engine to the wheels, the generator powers the EDMs to propel the vehicle and recharges the battery as needed, ensuring extended range under load conditions, while benefitting from the torque of the electric engines that bring the vehicle’s dynamics to new heights.
“Like STLA Medium and STLA Large, STLA Frame combines an unprecedented range with new levels of capability and performance to offer best-in-class range, payload and towing for our customers who need reliable and powerful trucks and SUVs, to haul their families or power their businesses,” says Carlos Tavares, CEO of Stellantis.
“With full EV and extended-range EV tech coming soon, we’re bringing ‘no compromise’ solutions to buyers who may be hesitant on trying their first electric vehicle. We’re proud of this engineering marvel and look forward to seeing it come to life in our upcoming product blitz on Jeep and Ram.”
STLA Frame is built using advanced, high-strength steel, delivering improved durability and rigidity with less weight. The widened center section houses the battery pack, with reinforced frame rails that protect the battery in the event of a side impact.
A full-length belly pan reduces aerodynamic drag to help maximize driving range, underscoring Stellantis’ commitment to efficiency without sacrificing performance.
The platform is designed for a BEV range of up to 500 miles and a REEV range up to 690 miles. It accommodates liquid-cooled battery packs ranging from 159 to more than 200 kilowatt-hours. It’s also engineered to accept future energy storage technologies, ensuring adaptability for years to come.
Stellantis designed and assembled front and rear EDMs, rated up to 250 kW, that deliver all-wheel-drive capability and can propel a vehicle from 0 to 60 mph in 4.4 seconds. Flexible suspension designs, including air suspension, offer an optimized ride for diverse driving conditions and loading scenarios.
Key STLA Frame metrics:
- Overall length range: 216-234 inches
- Overall width range: 81.2-83.6 inches
- Wheelbase range: 123.7-145.3 inches
- Ground clearance range: 6.6-10.3 inches
- Maximum tire diameter: 32.8/33 inches
- Charging Flexibility and Bi-directional Power
STLA Frame supports fast charging, according to Stellantis. In BEV configurations, 800-volt DC fast charging up to 350 kW can add 100 miles of range in just 10 minutes, while REEVs can achieve up to 50 miles in 10 minutes with 400-volt DC fast charging at up to 175 kW.
Vehicles with STLA Frame are equipped with bi-directional charging capability, allowing the vehicle’s battery to charge another EV, power a home in an emergency or feed electricity back to the grid.
