- Ford showed dealers a prototype of the upcoming four-door Mustang.
- The performance sedan will reportedly feature a hybrid V8 powertrain.
- It will rival the upcoming V8-powered 2029 Chevrolet Camaro sedan.
Ford is speeding up its plan to grow the Mustang family with a four-door sedan, and new details point to electrification playing a real part under the hood without giving up the V8 rumble. This is the car Ford has previously called the Mustang Mach 4, and it now exists as more than a sketch.
A Lot Of Fours, But The Eight Stays
At a private dealer gathering in Las Vegas, the Blue Oval pulled the covers off the first physical prototype, as we recently reported. People at the event say Ford told them it would come in under $40,000 and hit 60 mph in less than 4.0 seconds, with several attendees likening its size and shape to a Porsche Panamera. That is a lot of fours in one car: four doors, Mach 4, $40,000, and (under) 4.0 seconds. The number-crunching was not the end of it, either, because more slipped out at the same event.

Two people who attended last week’s gathering told The WSJ that the Mach 4 would run hybrid power, and one of them specified a hybrid V8. A setup like that would let Ford meet tightening emissions rules while keeping the combustion character that defines a muscle car, rather than going fully electric the way the Mach-E crossover did. It would thread a needle the Mach-E never tried to.
Built On Familiar Bones?
Rumor also has the car riding on a stretched version of the current Mustang’s chassis, which would trim Ford’s R&D spend and lean on hardware the company already knows well. Our best read on the exterior design is still the official sketch shown back in 2022, though dealers have now seen both a rendering and the physical prototype. Those in the room describe a footprint close to the Panamera’s, with styling cues lifted from its two-door sibling.


The Mach 4 is expected to reach roads closer to the end of the decade, part of Ford’s push to widen the Mustang name as buyers drift toward more practical body styles. The pony car is still the best-selling sports car in the world, yet US sales have fallen from more than 122,000 units in 2015 to around 45,000 in 2025. Ford would rather grow the badge than watch it shrink.

General Motors is also preparing its own four-door Camaro revival, this one with rear-wheel drive, a V8, and possibly a manual gearbox, though it has reportedly slipped to the 2029 model year. The Dodge Charger is another rival, and that one is already on sale with turbocharged inline-six and fully electric options, though a V8 said to be on the table too.
