Rumors pertaining to the future arrival of a Ford Mustang four-door sedan 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 Mustang sedan, 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 – a term the automaker filed to trademark back in March.
Thus, a Mustang four-door certainly seems to be likely at this point, even if it isn’t necessarily just a sedan version of the existing pony car, leaving us with an important question – what sort of platform will it ride on? It seems as if Ford wants the Mustang sedan to be a full-fledged family car, one that would re-add a sedan-like vehicle to the current lineup. As far as we can tell, there are two obvious options – an adaptation of the S650 Mustang’s architecture, or the CD6 platform.
S650 Platform
The S650 platform is the obvious choice, and will essentially make it a true four-door Mustang. This will allow Ford to keep development costs to a minimum by reusing many of the same components, including powerplants and transmissions. The downside with this option would be a lack of all-wheel drive – which will likely be a key feature for a Mustang sedan if Ford wants to sell it in decent numbers. This is especially important if it will be a true replacement for the discontinued Ford sedans.
To bring AWD to the S650 platform, Ford will need to invest a pretty penny to modify the architecture enough. And if it comes to doing that, then why not use a different platform that’s already capable of AWD?
CD6 Platform
Back in 2018, a report surfaced indicating that the S650 generation Ford Mustang would be underpinned by the CD6 platform – shared with the Ford Explorer and Lincoln Aviator – but obviously, that never happened. As Ford Authority exclusively reported back in October 2020, The Blue Oval had no plans to use the CD6 platform for smaller vehicles, however. Regardless, though it may seem like a stretch, there are some obvious benefits to using the CD6 platform in a Mustang sedan.
That platform is rear-wheel drive with a longitudinally-oriented engine, making it proper for a sporty car, which is precisely why that rumor surfaced years ago, in the first place. The Explorer ST has proven that the platform can support a performance-focused, solid-handling vehicle, which can be made even more so with the right upgrades – look no further than Steeda’s own Explorer ST with its lowered stance and rowdy exhaust. Additionally, the CD6 platform can natively accommodate all-wheel drive, if Ford opted to go that route with a four-door Mustang.
Given this information, we’re curious to hear what our readers think – which of these two platforms should Ford use in the forthcoming Mustang four-door sedan? Let us know what you think in the poll below!

DON’T make a 4-door Mustang and then rely on it to cover the entire sedan market. The biggest problem with current sedans is low entry and exit heights and this will be even worse. I’d say just don’t bother, period.
But if it is, it has to be at most the current size of the Mustang, along the lines of the Dodge Charger… and there has to be a hybrid and V8
Or you could leave the GTD in place of the current Mustang and develop the sedan on the basis of the S650… with the gradual drop in sales the value may not have much influence
