Ford Racing has been building fast Mustangs for decades. Building two of them at once, with entirely different definitions of fast, is the more interesting trick. The new Mustang Dark Horse SC convertible arrives alongside the coupe that debuted in January, and while both wear the same badge, they were engineered for drivers who want almost nothing in common from a performance car.
Chief program engineer Arie Groeneveld draws the distinction plainly: the coupe was built to set lap times. The convertible was built for the open road. Ford’s framing is that this duality traces back to 1966, when the company sent GT40 race cars to Le Mans to beat Ferrari, then turned around and built street-legal versions of the same car for customers who would never see a circuit. The organization learned how to do both without compromising either. That institutional memory, Groeneveld argues, is what makes the Dark Horse SC convertible possible now.
The convertible carries the distinction of being the first new high-performance Mustang convertible since 2013, and Ford calls it the most powerful open-air Mustang ever. Specific output figures have not been disclosed, but the SC designation signals forced induction sitting on top of the Dark Horse’s flat-plane crank V8. The coupe version of the Dark Horse SC is the most powerful Dark Horse yet, and the convertible shares the same engine architecture.
Where the coupe pulls from endurance racing programs, including Ford’s Le Mans campaigns, the convertible was tuned for a different kind of sensory experience. Groeneveld is specific about what dropping the roof changes: the driver gets direct access to the engine’s soundtrack, the wind, and what he describes as the smooth character of a car cruising a winding road rather than attacking one. Grand touring, in other words, rather than track assault. The suspension tuning, driving dynamics targets, and the overall character of the car were set accordingly.
That kind of deliberate split within a single model family is genuinely rare. The Dark Horse SC coupe already sits at the serious end of the Mustang lineup, incorporating lessons from the Mustang GT3 racing program and technology filtered down from the GTD supercar. The convertible takes that same foundation and redirects it. Same engine, different priorities.
The timing is worth noting. The Chevrolet Camaro and Dodge Challenger exited production after 2024, leaving the Mustang as the only traditional muscle car still being built. Ford sold 45,333 Mustangs in 2025, down from 53,159 in 2023, in a segment that no longer has a segment. The Dark Horse SC convertible is not a volume play. It’s a statement about what a Mustang can be when the competition clears out and the brand has room to define the category on its own terms.
Ford Racing is also marking its 125th anniversary with the Dark Horse SC launch, tying the car explicitly to a century-plus of motorsport heritage. Groeneveld spent 31 years at Ford before taking on this program, working across body engineering, powertrain, and program management. His read on the Mustang, after finally getting to work on one, is that its emotional pull comes from something that doesn’t belong exclusively to track drivers or street drivers. A Mustang, he says, works for both, and the organization proved it can build for both simultaneously.
Pricing and on-sale timing for the Dark Horse SC convertible have not been announced. The coupe debuted in January; the convertible follows. Full specifications are expected ahead of the on-sale date.
The Camaro is gone. The Challenger is gone. Ford just built two versions of the only car left standing, and one of them is the most powerful open-air Mustang in the nameplate’s history. The other one chases lap times. Between those two, Ford has covered a lot of ground.
