Ford showed dealers a four-door Mustang, and it reportedly keeps the V8 alive as a hybrid
Ford has reportedly shown US dealers a near-final design for a four-door Mustang saloon, codenamed Mach 4, at a private conference in Las Vegas.
The reveal, first reported by Automotive News and the Wall Street Journal citing people who attended the closed-door meeting during the week of 3 August, follows an Autocar report from May 2024 that first flagged Ford's plans for a four-door Mustang. Dealers were reportedly shown a car similar in size and shape to a Porsche Panamera, with a 0-60mph time (0-97km/h) claimed at under 4.0 seconds, at a gathering also attended by Ford Executive Chair Bill Ford and CEO Jim Farley. Ford declined to comment when approached by Autocar about the reports.
What dealers were actually shown
The car has reportedly been trademarked under the name Mach 4, a nod to the range-topping Mach 1 badge while keeping clear water between it and the electric Mach-E SUV. Sourcing points to a stretched version of the current Mustang coupe's platform rather than an all-new architecture, with styling said to draw on an official Ford sketch that first surfaced in 2022. Pricing is reportedly targeted below $40,000 (roughly €34,600; Autocar's own conversion puts it at around £30,000), and the claimed sub-4.0-second 0-60mph time would put it in the same performance bracket as the standard Mustang GT.
Why hybrid, and why now
The headline detail is that the V8 survives, but only as a hybrid, widely believed to be built around the naturally aspirated 5.0-litre Coyote V8 already fitted to the Mustang coupe. US emissions rules have loosened considerably under the current administration, but Europe and Asia are tightening theirs, and hybridisation is reportedly the mechanism that lets Ford keep offering a V8-based product globally rather than just at home. Farley has been blunt about the priority: Ford will keep building V8s, he has said, “as long as God and the politicians let us.” The broader business case sits alongside a steep decline in Mustang's US sales, from around 122,000 units in 2015 to roughly 45,000 in 2025, giving Ford a clear incentive to widen what “Mustang” can mean rather than watch the nameplate shrink.
Farley has been signalling this for years
This isn't a sudden pivot. In an interview with Autocar roughly two years ago, Farley drew a specific line: “Never build a Mustang that isn't a Mustang.” He was equally specific about where that line sits: “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.” He has also ruled out a pure-electric Mustang beyond the Mach-E, arguing that battery-electric performance, however capable in motorsport or at companies like Rimac, “just isn't right” for the nameplate.
The competition is already circling
A four-door Mustang would land in a segment increasingly crowded with domestic rivals. Dodge already sells the four-door Charger with a turbocharged inline-six and electric options, and Chevrolet is reportedly working on its own four-door Camaro for around 2029, expected to keep a V8, rear-wheel drive and possibly even a manual gearbox. Longer term, the ambition attributed to Ford is bigger than just the domestic muscle-car set: dealers were reportedly told to think of the Mach 4 as aiming at cars like the BMW M3 and Audi RS5.
Whether it goes global is still an open question
Ford has not confirmed export plans for the Mach 4, and the WSJ's reporting only points to a launch “closer to the end of the decade,” with sources split on whether that means 2028 or 2029. Ford Europe's passenger vehicles chief, Christian Weingärtner, told Autocar the company would consider global models where it sees sufficient demand, and that Ford sees “great opportunities” in segments beyond small and family crossovers. Farley himself has framed taking the current Mustang coupe global a decade ago as “a big risk” that “paid off,” a comment that reads, in context, like a case being built for doing it again.
AutoNext Take
The interesting thing here isn't that Ford is considering a four-door Mustang. Farley all but told us that two years ago. It's that the reported specifics, a Panamera-sized body, a hybridised Coyote V8, a sub-4.0-second 0-60mph claim, and a sub-$40,000 target, suggest this has moved well past a mood board and into something dealers were shown as a near-final design. Nothing here is officially confirmed, and Ford's declined comment means all of it should be read as reported rather than announced. But if the hybrid V8 detail holds up, it's a genuinely interesting answer to a problem every performance nameplate is wrestling with: how to keep the character intact while emissions rules pull in different directions on different continents. A four-door Mustang isn't the part that would have surprised us. A four-door Mustang that still sounds like a Mustang would.
