The Ford Authority Take
Rumors of a four-door Ford Mustang have swirled for many years to this point, and in fact, that very concept dates back to a time when the first example of the original, first-generation pony car had even been sold. Back in the fall of 2018, word got out that The Blue Oval was thinking about building a four-door Ford Mustang sedan, and about a month later, Ford reportedly showed such a concept to dealers. Then, in June 2020, a report surfaced claiming that a four-door Mustang was indeed “on the table,” but it was a few years before that rumor intensified.
Then, in May 2024, Ford CEO Jim Farley himself said that he “believes” the automaker could make a four-door Mustang, so long as it has “all the performance and attitude of the original.” A few months later, in August, Ford reportedly showed a number of renderings, mockups, and photos of some future Ford Mustang variants, which included a four-door coupe reportedly called the Mach 4, as well as a lifted, off-road, Baja-style model with rugged tires, an RTR-modified Mustang EcoBoost with a $40k price tag, and a high-performance, V8-powered convertible that looked a lot like the older Shelby GT350/GT500 variants, albeit, sans any Shelby badging. Just this past January, Executive Chairman Bill Ford didn’t rule out a four-door Mustang, either.
As Ford Authority exclusively reported last September, Ford actually created a design study of a four-door Mustang sedan based on the S197 generation model some time ago. The automaker even went so far as to create a full-scale model of this Mustang sedan around 2005, though unfortunately, photos of that model are unavailable, and like all design studies, this was an internal concept that was never shown to the public. Obviously, that model never came to fruition, though now, the reality of a Ford Mustang sedan seems to be as strong a possibility as it ever has been, given the appearance of this new trademark filing.
Comments
Naturally. Ignore the heart of the market and expand the BoyRacer lineup. What else did you expect?
The best would be to built a real 4 door sedan like the Fusion/Mondeo, but least a 4 door Mustang has much more sense than the Mach-e which definitively is NOT and will NEVER be a Mustang.
A 4 door isn’t a Mustang either since the whole idea was a sporty, euro styled, 2 door. They even knew it wasn’t for families, yet the car was successful for 60 years. Started a whole segment based off of its body-style too. Farley is disconnected from his audience and it is time for a change in leadership.
I think building a 4 door from the Mustang platform, if they are able to do it right, is a great idea. Just don’t slap the Mustang name on it. The EV CUV they slapped the Mustang name on is an abomination, they could not have chosen a worse segment to dilute the name on.
John, at this point I wouldn’t be surprised if the called it a Mustang-Bronco-St-Line Mach 4…..Then of course throw in a “gotta have it” black package for a reasonable $2,995 which will just swap wheels and badges, which cost Ford no real net difference. If there was ever a company being totally misguided, it’s the current FoMoCo.
The 4-door S650 belongs as a Lincoln LS V-8 not a Mustang. Rule 1, you can’t have a Lincoln faster or better than the Mustang. Ford is doomed under the current leadership.
“Mustang” Mach E= MINO – Mustang in Name Only…
BFM, That’s Big Mistake, if Ford wanted to make a really big splash with the Mustang, make it a larger version like the 1974 still as a 2 door but with enough room in the back seat to accommodate two adults. Gosh what a better idea than an ugly 4 door.
Make Mustang affordable again, oh that’s right not profitable enough that’s not a good business model.
This car will be so expensive Ford will wonder why it didn’t sell. With the standard V8 GT Mustang already over 48k with destination charge the four door will 55k easy.
Beginning of the end for the Mustang that stuck around for 60 years. Sales will just dip even lower in favor of the sedan, then eventually Ford will be like “well let’s just keep the sedan and kill off the Mustang, the sedan still has all the attitude of the original.”
If they do make a Mach 4, I think instead of it being a 4-door sedan, it makes more sense that it will be an ICE 4-door crossover or wagon. Sedans are not selling well in the US. If Ford is going to further drag the Mustang name through the mud, I would rather have a V-8 practical crossover than a sedan; especially if they make a 4-door “coupe”. In spite of being 4 doors, the back seats of those “coupes” often have reduced head room.
Everybody saying it shouldn’t have the MUSTANG name, you know you’re dreaming. Farley has a formula to make Ford AWESOME!! You just take a popular name or badge and slap it all over EVERYTHING! This will allow insane markup. Think of what should have been the reinvented Escape that was dubbed B R O N C O (Sport). Great little CUV, but shamefully watered the Bronco name. And in the process they ruined the Escape. 2 for 1 screw up there Jimmy Boy!! Then my favorite is “ST-Line”. The ST was actually growing a good following with the Edge/Explorer so of course we need to water it down. This company is lost!! I just bought my F-150 last month before they finally screw it up.
The future Mustang should either be smaller and lighter with no pretense at a back seat, or 6 inches longer and have a rear seat that adults can use. I had a 86 GT with the useful hatch and a back seat that was suitable for adults. But 2 doors is plenty. If Ford brings back a 4 door sedan that might work but DO NOT call it a Mustang.
I don’t know where to begin other than “What are they thinking?”
A 4 door Mustang = REALLY BAD IDEA.
A 4 door (pull out one of the other drawer full of names that Ford has had that had 4 doors)= A good idea as long as it doesn’t look like a Mustang.
And after the 4-dr Mustang is released, I suggest you follow up with a 2-dr, 3 row Expedition that seats 9 people.
At least it has a V8.
It most likely won’t have anymore leg room in the back seat!
And it will be pricey, I am sure.
Ford needs to make a line of sedans. Toyota never gave up on the Corolla or Camry and they sell a boat load of them. Both are very nice.
I can see the marketing rationale for this, sure.
But no way…nooo waay will Ford be able to offer a vehicle that lives-up to the heritage of the nameplate.
I fully expect the car to be a modern day Ford Fairmont / Zephyr with Mustang badges and decals.
Watch and see.
Fairmont.
I’m curious if Ford even reads these comment sections. The past 2 days have been super negative about this naming scheme. It’s a pretty easy fix
If Ford ever makes a 4 door mustang anything. I hope and I MEAN I HOPE !!! NO ONE WILL EVER BUY ONE . Ford wake up really, didn’t you learn any thing with the f150 lighting. UNREAL .
Boo….. on the 4 door mustang anything.
I’m good with it. Just don’t give it a v8. ST trim should have a 415hp 3.0l ecoboost with awd. A performance option with a 450hp 3.5l ecoboost should join the lineup as the RS version. This way it’s separate from the coupe
A four door car should be called Continental! Would appreciate the return the Continental, not another Mustang! Mustang horse doesn’t carry four people well! Keep the Mustang for only two people, thanks!
A four door, V8 six speed manual car is exactly what the market is missing. Who cares what name is on it
