Is this what the Ford Mustang sedan will be called?

A recent trademark filing by Ford may have revealed the name of the rumoured Mustang sedan.

Ford Authority reports Ford filed to trademark the Mach 4 name with the United States Patent and Trademark Office (USPTO) on February 25, 2025, for use on a motor vehicle.

It’s the latest indication a Mustang sedan – something never before offered by the Blue Oval – is indeed coming.

Sources told Automotive News last August that Ford executives – including CEO Jim Farley – revealed a four-door ‘coupe’ version of the Mustang at a dealer meeting in Las Vegas.

It was part of a quartet of new Mustang variants, including a jacked-up, Baja-ready model, a modified turbocharged four-cylinder edition, and a “high-performance” V8 convertible with a manual transmission.

Ford reportedly didn’t share launch timings for the vehicles, but dealers came away believing the company was seriously considering putting them into production.

The four-cylinder performance model has eventuated as the RTR, though the remaining three haven’t been revealed yet.

Earlier in 2024, Mr Farley also appeared to hint a Mustang sedan was a possibility.

“We will never build a Mustang that isn’t a Mustang,” he told Autocar.

“For instance, there will never be room for a small, two-row Ford SUV with a Mustang badge stuck on it. But could we do other Mustang body forms – a four-door or whatever? I believe we could, as long as these models have all the performance and attitude of the original.”

A four-door Mustang could give Ford a rival to the new-generation Dodge Charger coupe and sedan, which replace the old Challenger coupe and Charger sedan.

With Ford saying it’s sticking with V8 power for its Mustang for as long as regulations permit it, a four-door model would still likely have that ace in the hole over the rival Dodge which will be offered only with electric power or a twin-turbocharged inline six.

Since production started in 1964, the Mustang has only ever been offered as a coupe, hatchback coupe or convertible.

Despite this, Ford has done mock-ups of other Mustang body styles over the years, including sedan and shooting brake versions of the first-generation model and even a wood-panelled wagon in the 1970s.

Ford Authority also reports Ford created a full-scale model of a sedan version of the fifth-generation ‘S197’ Mustang – which was never officially sold in Australia – around 2005. However, a production version never eventuated.

Ford has sold vehicles on the same platform as the Mustang with sedan bodies – after all, the first Mustang was based on the Falcon.

However, unlike its Mercury Cougar cousin which launched later in the 1960s, the Mustang was never allowed to stray too far from its intended purpose of being a relatively affordable sporty coupe.

The Cougar, in contrast, continued to grow in size and plushness in the 1970s, and eventually its nameplate was applied to sedan and even wagon models.

There’s a caveat here, as Ford did expand the Mustang nameplate to a wildly different vehicle: the electric Mustang Mach-E crossover. However, it has continued to be sold alongside the more traditional Mustang pony car.

Should the Mustang gain a sedan – or “four-door coupe” – body style, it would be the only vehicle of this type in Ford’s US lineup.

Over the past several years, Ford has discontinued its Fiesta, Focus, Fusion and Taurus models there, all of which were offered as a sedan.

If you want a Ford sedan, you need to go to China or the Middle East where the new-generation Mondeo/Taurus is sold.

The last time Ford offered a sedan in Australia was in 2018 with the Focus, while local production of the Falcon wrapped up in October 2016.

Even Ford’s luxury Lincoln brand no longer sells sedans in the US market, despite being known for four-door models like the Town Car and Continental. However, the Mondeo/Taurus has a luxurious Chinese-market cousin called the Lincoln Z.

Passenger cars in general are becoming harder to find in Ford’s global lineup. The Fiesta is dead, while the Focus is set to exit production this year.
