Ford ‘Mach 4’ Trademark Fuels Future Mustang Sedan Rumors

Ford Motor Company has sparked fresh speculation in the recent month about a potential four-door version of its beloved Mustang pony car, after filing for the name “Mach 4” with the U.S. Patent and Trademark Office (USPTO). The news comes just as Dodge gears up to launch its next-generation Charger four-door muscle car for the 2026 model year. 

A Mustang Sedan in the Making? – 

The idea of a Mustang sedan has circulated for years. Ford Authority reports that discussions date back to the original Mustang’s era, with renewed interest surfacing in 2018 when the automaker allegedly showed a concept to it’s dealers. Ford CEO Jim Farley even stated last year that a four-door Mustang could happen if it retained the “performance and attitude of the original.”

While Ford has already tested the waters by branding the all-electric Mustang Mach-E crossover under the iconic pony car name, a proper Mustang sedan could target performance enthusiasts who need extra practicality without sacrificing power.

Could the Mach 4 Be Something Else? – 

There’s also a possibility that “Mach 4” refers to something entirely different—like the rumored Ford Raptor supercar. Earlier this year, Farley hinted to Top Gear that Ford was working on a standalone off-road supercar, saying, “We’re in the middle of creating something… but the question is, should Ford make an off-road supercar?”

If the Mach 4 name is tied to that project, it could be an entirely new performance vehicle rather than a Mustang-based sedan.

A Challenger to the Four-Door Dodge Charger? – 

If Ford is indeed preparing a four-door Mustang, it would go head-to-head with the 2026 Dodge Charger. The upcoming Charger four-door will debut in multiple forms, including the all-electric Daytona models (456 horsepower R/T and 590 horsepower Scat Pack) and the gasoline-powered Charger SIXPACK, which packs 420 horsepower from a twin-turbo 3.0-liter HURRICANE I6 engine. All models come with standard all-wheel drive (AWD).

Final Thoughts – 

A four-door Mustang would undoubtedly stir controversy among purists, but Ford has already broken tradition with the Mustang Mach-E. If this latest trademark filing leads to a production model, the muscle car wars could soon start again with Ford now going after Dodge full circle.

For now, enthusiasts will have to wait and see whether the “Mach 4” turns into a high-powered Mustang sedan or if it’s another dead-end trademark.
