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.

I think when this, and the semi-solid state batteries arrive for the STLA: Large vehicles, that's when we're going to see the Charger EV (and others) become decent vehicles. Imaging the Daytona Scat pack with it's 670hp, less weight and better gearing makes an already fast car even faster. While it's not conventional, it will be interesting to watch Mopar's EVs carve their niche in this world with whatever Stellantis North America cooks up.

I stated from the mention of this 3 speed that it was for EVs but people seemed to think this was for hybrids, which made no sense whatsoever. A transmission like this only could be an upgrade to the current 1 speed they have.

Doesn't the gearing improve the efficiency of the battery due to different speeds?
Why not make a manual option for the charger EV???

What about the reported three speeds in the upcoming Cherokee hybrid. Same?
Different? It could be a big deal for these hybrids and electrics. Maybe.

This is the same transmission they have been talking about, it was never for hybrids. The Cherokee will likely get a ZF 8 or 9 speed hybrid transmission. They won't use the Punch DCT in the US because the North American markets hate DCTs.

Cherokee will have the 1.6 with a 3 speed hybrid transmission
