Stellantis Secures Patent for Three-Speed EV Gearbox
New Gear Reducer Boosts Off-Road Torque, Towing, and Drive Efficiency
Stellantis (FCA US, LLC) has officially been granted a U.S. patent for a newly developed three-speed gear reducer for electric drive modules (EDMs), opening the door to smarter, more capable EV drivetrains across its brands. The patent on the United States Patent and Trademark Office (USPTO), filed on October 25, 2023, and granted May 1, 2025, outlines a compact but powerful solution aimed at delivering both off-road grunt and highway efficiency—two performance goals often at odds in today’s single-speed electric vehicle (EV) designs.
