by New Stellantis Patent on a Tri-Motor System
Stellantis is actively working on electrification, despite the recent hype around the return of the Hemi V8 engine. The company’s new patent describes a torque management system between three electric motors and an additional torque source, which is likely a gasoline generator. This indicates the development of new electric vehicle models with an extended range.
Technical Details of the Patent
Patent WO/2025/184156 addresses solving a three-dimensional optimization problem for balancing torque between each motor and the generator, while simultaneously maintaining battery charge. This is essentially a guide for managing a complex EREV platform.
The patent was filed by FCA US LLC (the official Stellantis entity in North America) and published on September 4, 2025. The document first discloses information about a tri-motor EREV configuration from the automaker.
Potential Applications of the System
The most obvious candidate for this powertrain is the next generation of Ram pickup trucks. The Ramcharger already uses an EREV layout, and a tri-motor version could compete with the Tesla Cybertruck thanks to a greater range and improved traction.
Experience of Chinese Manufacturers
In China, the Maeextro S800 model combines three electric motors with a 1.5-liter turbo generator, providing a range of up to 1333 km. The Yangwang U8 uses four separate wheel motors along with a 2.0-liter engine, demonstrating supercar-level performance and a range of nearly 1000 km. This could inspire Chrysler to create a new Imperial flagship with a similar powertrain.
The Future of the Chrysler Brand
Currently, Chrysler only sells minivans, and the brand has not had a true flagship since the debut of the 300 model. Now is the perfect time to introduce a unique powertrain that could revive interest in the brand.
The development of EREV technologies opens up new possibilities for automakers, especially in the realm of heavy vehicles where range and power are critical factors. Stellantis appears to be trying to combine the benefits of electrification with the practicality of traditional engines, which could be the key to the mass adoption of electric vehicles in the future.
