Stellantis Launches Multi-Energy Platform

Stellantis NV (Stellantis) unveiled the STLA Frame platform, a battery electric vehicle (BEV)-native, multi-energy platform engineered for full-size body-on-frame pickup trucks and SUVs. The platform is designed to deliver range of up to 690 miles (1100 km) with the range-extended electric vehicle (REEV) option and 500 miles (800 km) in BEV, a maximum towing capacity of 14,000 pounds (6350 kg) and a payload rating of 2700 pounds (1224 kg). Additionally, the platform supports water fording up to 24 inches (610 mm), making it ready for challenging environments and diverse use cases.

Intended to underpin Stellantis full-size pickup trucks, light commercial vehicles, and SUVs, Stellantis said that STLA Frame can also 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.

“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,” said Stellantis chief executive officer Carlos Tavares. “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.”

Stellantis said that 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 accommodates liquid-cooled battery packs ranging from 159 kWh to more than 200 kWhs. 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, 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, according to Stellantis.

Key STLA Frame metrics:

• Overall Length range: 216-234 inches (5488-5941 mm)
• Overall Width range: 81.2-83.6 inches (2062-2124 mm)
• Wheelbase range: 123.7-145.3 inches (3143-3690 mm)
• Ground clearance range: 6.6-10.3 inches (168-262 mm)
• Maximum tire diameter: 32.8/33 inches (834/838 mm)

STLA Frame supports fast charging. In BEV configurations, 800-volt direct current (DC) fast charging up to 350 kW can add 100 miles (161 km) of range in just 10 minutes, while REEVs can achieve up to 50 miles (80 km) 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.

The STLA Frame platform is one of four global BEV platforms at the core of the Stellantis Dare Forward 2030 strategic plan. Following the release of the STLA Medium in July 2023 and STLA Large in January 2024, this platform lineup ensures Stellantis can deliver the right solutions for customers based on a wide variety of electrification adoption scenarios. All Stellantis global platforms are designed and engineered for extended lifecycles via the interchangeability of battery cell chemistry, EDMs, power inverters and software control.

Stellantis is investing more than US$52.7 billion in electrification through 2030 to reach a 100% passenger car BEV sales mix in Europe and a 50% passenger car and light-duty truck BEV sales mix in the US by 2030.
