Ford Mustang Dark Horse SC: The New Extreme Pony Car

‘Son of GTD’. Or perhaps its brother. That is the easy shorthand, yet the new Mustang Dark Horse SC proves Ford’s 911 GT3 RS-chasing extreme Mustang was only the beginning. Who would have thought the Blue Oval’s modern pony car had such outrageous breadth of ability?

“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 invigorated by its partnership with the Red Bull Formula One empire, Ford Racing has gathered every world-class component at its disposal and created a fresh mix. The powerplant is the same supercharged 5.2-litre V8 fitted to the GTD. That car produces 804bhp, while Ford is currently refusing to reveal the SC’s output.

Choose a figure halfway between the Dark Horse’s 493bhp and the GTD’s total and you will be close to the SC’s territory, so let us suggest 700bhp. It could be higher, particularly if you recall the previous GT500, which delivered 750bhp – and frequently more, depending on which aftermarket tuner had worked its dark magic. Whatever the final figure, this is emphatically combustion-powered horsepower, accompanied by an appropriate soundtrack. TopGear.com previewed it at Ford’s Detroit headquarters and required a brief lie-down afterwards.

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

Mustang Dark Horse SC chassis and braking upgrades

There will be a standard SC, if that description can really be applied, alongside a Track Pack model; Track Pack special editions will launch the range. Personalisation is a hugely profitable business for premium car manufacturers, and Ford wants its share. Every Mustang Dark Horse, however, receives MagneRide dampers featuring the latest-generation hardware and software, firmer-rate springs, revised front and rear knuckles, and modified front control arms. Rear-suspension geometry has also changed, while the steering rack and track rods have been updated. The regular SC gets substantial Brembo brakes too, with 419mm front discs and six-piston calipers.

But it is the Track Pack that really grabs our attention. Its MagneRide system is retuned, while carbon-fibre wheels lower unsprung mass. These wear bespoke Michelin Pilot Sport Cup 2 tyres: 305/30 R20s at the front and 315/30 R20s at the rear, which Ford says provide traction approaching supercar levels. The GTD’s five-stage variable traction control system is included, with full ESC deactivation available if you want to set fire to those expensive Michelins. Carbon-ceramic brakes also form part of the package, helping the Track Pack shed 68kg against the standard SC.

Track Pack aerodynamics and exterior design

Neither the SC nor its Track Pack counterpart could be described as visually understated. Yet they still establish another distinctive identity for the Mustang, that endlessly giving American muscle-car gift. The SC significantly raises not only the car’s dynamic abilities, but also the punishment it can withstand on circuit; the bulk of the styling revisions is intended to make it virtually bulletproof in that environment.

Lead designer Aaron Walker calls the redesigned front end “sinister”, and it offers considerably improved cooling for the engine and brakes. An aluminium bonnet with an enormous vent also features. At the back are a substantial diffuser, clever underfloor aerodynamics and a frankly enormous rear wing. The Track Pack adds a ducktail at the bootlid’s edge, plus carbon stanchions and end plates. The outcome is greater downforce, although the overall aerodynamic balance has been developed to inspire driver confidence. That matters even for owners who are relatively new to this level of performance, as many Mustang buyers are.

Personalisation options for the Mustang Dark Horse SC

As mentioned, buyers can go wild with bespoke paint finishes and interior trim, and the SC is willing to test the boundaries. Beyond the carbon exterior package, there is also a Teal Accent Package. Yes, we know, but we have seen it and 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 exterior paint available. Despite its monumental performance, much of the Dark Horse’s attraction lies in its 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. There is still no information on pricing, kerb weight or whether the SC will come to Europe. Those are questions we will answer soon…
