The Ford Mustang, an iconic symbol of American muscle cars, may soon transform dramatically. Ford has recently registered the name “Mach 4” as a trademark with the U.S. Patent and Trademark Office, hinting at the possibility of a four-door version of the Mustang. This shift could mark a significant departure from the model’s long-standing tradition as a two-door sports coupe, and some industry experts call it a bold move by Ford, especially after the success of the Mustang Mach-E crossover.


The Concept of a Mustang Sedan: A Long-Standing Rumor
The idea of a four-door Mustang isn’t entirely new. Ford teased the concept in 2022 when it released an official sketch of a four-door version based on the 7th-generation Mustang. Recently, speculation was further fueled when a dealer meeting in Las Vegas featured another rendering of the four-door Mustang. In the 1960s, Ford even produced a prototype of a four-door Mustang, and in the mid-2000s, a sedan model based on the S197 generation Mustang was developed, but it was never released to the public.
However, the current climate is different. The Mustang brand has expanded, and there is growing interest in diversifying its lineup. With the increasing popularity of sedans and crossovers, the market atmosphere has shifted, making the idea of a four-door Mustang more plausible.


Potential Powertrain and Design Features
If Ford moves forward with the Mach 4, it will likely share the powertrains used in the current Mustang. The 5.0-liter V8 Coyote engine and the 2.3-liter EcoBoost turbocharged 4-cylinder engine in the Mustang GT are strong candidates for the new model. Given Ford’s emphasis on electrification, hybrid and pure electric versions of the Mach 4 are also possibilities.
The Mach 4 is designed to retain the signature Mustang features, including the bold front grille and rear styling, but with a more streamlined roofline. Elements such as a black roof and side skirts will maintain the sporty appeal, creating a sleek yet muscular presence on the road.
Controversy and Market Expectations
The idea of a four-door Mustang will stir controversy among enthusiasts who associate the Mustang name with its iconic two-door coupe design. Similar reactions were seen when the Mach-E, a fully electric crossover, was first introduced, with many fans reluctant to embrace a Mustang in SUV form. However, some argue that this move is necessary for brand expansion, as consumer preferences evolve and demand for more versatile vehicles grows.
Whether Mach 4 will become a reality or remain just another intriguing rumor remains to be seen. Regardless, Ford’s exploration of a four-door Mustang reflects the changing automotive landscape and the brand’s ambition to adapt to modern consumer needs while keeping the Mustang legacy alive.
