Ford Mustang Dark Horse SC: GTD’s Loud New Sibling

The ‘son of the GTD’ – or perhaps its sibling – is the simplest way to describe it. Yet the new Mustang Dark Horse SC proves Ford’s 911 GT3 RS-chasing Mustang GTD was merely the beginning. Few would have expected the Blue Oval’s modern pony car to possess such extraordinary breadth of ability.

Mustang Dark Horse SC powertrain and chassis

“To engineer Mustang Dark Horse SC, we tested alongside the Mustang GTD and GT4 at some of the most challenging tracks in the world, using those elite Mustangs as benchmarks,” Chief Programme Engineer Arie Groeneveld says. “The result benefits from every hard-won lesson we’ve learned at the very top of the performance ladder.”

That performance ladder is tall enough to wash the windows of a Manhattan skyscraper. Newly energised by its association with Red Bull’s Formula One operation, Ford Racing has gathered every top-tier component at its disposal and created a new mix. Its engine is the same 5.2-litre supercharged V8 used in the GTD, where it produces 804bhp. Ford is not yet revealing the SC’s output.

Choose a figure halfway between the Dark Horse’s 493bhp and the GTD’s power and you will be close to the SC’s territory, so 700bhp seems a sensible estimate. It could be higher, particularly considering the previous GT500 offered 750bhp – and frequently more once an aftermarket tuner had worked its magic. Whatever the final number, it is emphatically internal-combustion power, accompanied by an equally emphatic noise. TopGear.com previewed the car at Ford’s Detroit headquarters and was left needing a brief lie-down.

“It’s a soundtrack that rival sports car makers have largely abandoned,” Ford says with some justification. This machine is L-O-U-D.

There will be a standard SC – if that is really the right word – alongside a Track Pack model, with Track Pack special editions arriving first. Bespoke personalisation is a very profitable business for premium manufacturers, and Ford wants its share. Every Mustang Dark Horse SC nevertheless receives MagneRide dampers with the newest hardware and software, firmer-rate springs, fresh front and rear knuckles, and revised front control arms. Ford has also altered the rear suspension geometry and updated the steering rack and tie rods. The regular SC comes with substantial Brembo brakes too: 419mm front discs and six-piston calipers.

Track Pack brakes, tyres and weight saving

The Track Pack is the one we really want. Its MagneRide system receives a dedicated recalibration, while carbon-fibre wheels cut unsprung mass. Ford fits bespoke Michelin Pilot Sport Cup 2 tyres: 305/30 R20s at the front and 315/30 R20s at the rear, delivering what it describes as near-supercar traction.

The GTD’s five-stage variable traction control system is carried over, while ESC can be switched off completely if you feel inclined to ruin those expensive Michelins. Carbon-ceramic brakes also feature, helping the Track Pack shed 68kg against the base SC.

Aerodynamics, styling and Mustang Dark Horse SC options

Neither version, including the Track Pack, could be accused of being visually discreet. Both establish another distinct identity for the Mustang, the American muscle car that keeps finding new forms. The SC substantially elevates its dynamic ability and the punishment it can withstand on circuit; much of the redesigned bodywork is intended to make it exceptionally robust in that environment.

Lead designer Aaron Walker calls the revised nose “sinister”, and it provides much better cooling for the engine and brakes. An aluminium bonnet with an enormous vent is included as well. At the rear sit a prominent diffuser, aerodynamic work beneath the floor, and an unashamedly huge rear wing. The Track Pack adds a ducktail to the bootlid edge, plus carbon stanchions and end plates.

The result is more downforce, although the overall aerodynamic balance is designed to inspire confidence in the driver. That matters even for owners relatively new to this calibre of performance, as many Mustang buyers are.

There is plenty of scope for individual paint finishes and cabin trim, and the SC is not shy about testing the boundaries. Alongside a carbon exterior package, buyers can choose a Teal Accent Package. Yes, we know – but having seen it, it works better than its name suggests. The Track Pack Special Edition adds a black-painted roof, Race Red brake calipers and exclusive graphics, with Shadow Black or Oxford White available for the exterior. Despite its immense performance, much of the Dark Horse’s attraction lies in the details and the street credibility it creates. The configurator is calling.

“The GTD, we know, is off the scale in terms of capability, but we identified some clear space between it and the Dark Horse,” says Groeneweld. “I can’t confirm where the SC sits on the spectrum, in terms of power output or price, but it certainly doesn’t cannibalise the GTD, I can tell you that. The SC could be a daily driver, and the Track Pack is obviously more circuit-oriented. The thing I’m most satisfied with is how we’ve delivered a level of track endurance for this car while maintaining a Mustang look.”

The order book will open shortly. Ford has not yet disclosed pricing, kerb weight, or whether the SC will be sold in Europe. Those answers should follow soon…
