Stellantis (FCA US, LLC) has been officially awarded a United States patent for an innovative three-speed gear reducer designed specifically for electric drive modules (EDMs), signaling a pivotal advancement in electric vehicle (EV) powertrain technology. The patent, filed on October 25, 2023, and granted on May 1, 2025, by the U.S. Patent and Trademark Office (USPTO), positions the automaker to deliver smarter, more versatile drivetrains across its EV lineup.
The newly patented gear reducer represents a leap forward in addressing one of the most persistent challenges in electric mobility: balancing low-end torque for off-road and towing performance with high-speed efficiency for highway travel. Traditional EVs typically utilize single-speed gearboxes, which, while mechanically simpler, limit drivetrain adaptability across varying driving conditions.
According to the patent filing, Stellantis’ three-speed gear reducer integrates a compact yet robust configuration that can shift seamlessly between ratios, offering increased torque at lower speeds and improved efficiency at higher speeds without sacrificing packaging space. This technology is expected to support a wide range of applications—from rugged off-road SUVs under the Jeep badge to high-performance EVs and even commercial vehicles.
Industry analysts suggest that this development could give Stellantis a significant edge in the competitive EV market, especially as consumer demand grows for electric models capable of handling diverse driving scenarios. The gear reducer may enable EVs from Stellantis to offer improved towing capacity, better range optimization, and enhanced overall drivability.
This innovation reflects Stellantis’ ongoing push to modernize its powertrain systems in alignment with its “Dare Forward 2030” strategy, which targets over 50% of sales in the U.S. and 100% in Europe to be battery electric vehicles (BEVs) by the end of the decade.
While Stellantis has not yet announced specific vehicle models to feature the new three-speed gear reducer, insiders speculate that future iterations of vehicles like the Jeep Recon, Ram REV, or even high-performance Dodge EVs could incorporate this groundbreaking system.
With this patent, Stellantis reinforces its commitment to EV innovation, offering a strong signal that traditional automakers are serious contenders in shaping the next generation of electric mobility.
