The World Is Ready For A Mustang Sedan

A new trademark filing from Ford suggests the long-rumored four-door Mustang may finally be in the works.
Ford recently filed the name "Mach 4" with the United States Patent and Trademark Office (USPTO) on February 25. The application states that the name applies to gasoline and electric automobiles, pickup trucks, SUVs, and their structural parts.
Key Points
- A new trademark filing for "Mach 4" suggests the Mustang sedan could be in active development.
- A Mustang sedan would likely share the S650 platform, with an extended wheelbase and a mix of EcoBoost and V-8 powertrains.
- Ford has already expanded the Mustang brand with the Mach-E SUV, proving its willingness to experiment with different body styles.
Apparently, Ford has even gone so far to show dealers renderings of a proposed four-door pony car at an event last year. Ford hasn’t confirmed anything yet, but Ford CEO Jim Farley is on the record stating that a Mustang can take any form “as long as the variants have all the performance and attitude of the original.”
If it happens, the Mach 4 would be the first-ever production Mustang sedan; more significantly, it would be Ford’s return to the U.S. sedan market, which it exited in 2020 with the discontinuation of the Fusion.
The "Mach" name has been associated with the Mustang since 1969 when Ford introduced the high-performance Mach 1 variant. More recently, Ford used it for the all-electric Mach-E SUV, which stirred controversy among Mustang purists.
Ford’s interest in a Mustang sedan isn’t new. Back in 2018, reports surfaced that the automaker showed a four-door Mustang concept to its dealers, with rumors resurfacing in 2020. Now, with the recent trademark filing and last year’s alleged dealer preview, the time could be right.

Is this the same writer that "explained" why the Mach-Ugly actually IS a Mustang (which it definitely isn't). I am not hearing anyone that wants a Mustang sedan, and I certainly don't want a 4 cylinder turbo-crap engine, or a V8. Now IF Ford had still made a Mustang that was like the six cylinder ones, with a durable transmission - and without electric parking brake, push-button start, cylinder deactivation, electric power steering - and that had a cool interior like my 99 Mustang does - not just black or eeech gray -
A sedan should be the Fusion/Mondeo or the Taurus. However, it has much more sense a 4 door Mustang (it can be focused to compete with the Porsche Taycan or the Porsche Panamera) than the atrocious Mach-e that definitively is not and will never be Mustang.
