Hennessey has done that thing again where it takes a fast car and makes it even faster, subjecting the Ford Mustang GT and Dark Horse models to outrageous amounts of power. New total? That’ll be around 850hp - 46 more than the ‘Ring record-setting GTD - plus 881Nm.
Customers can choose a base GT or Dark Horse model from a Ford dealer, who’ll then give them the option of fitting this ‘Super Venom’ package on top. It includes a wheezier supercharger, new injectors and an improved induction kit.

The result of those that extra shove is half a second off the 0-100kph time (now 3.2s), and over a second off a standing quarter-mile run for the Dark Horse. Naturally, the GT version will be slightly slower than this.

If you were to opt for the Dark Horse, you’d also gain the bits that remain an optional extra on the GT, such as an active exhaust, limited-slip differential and adaptive damping. The choice of swapping a standard 10-speed automatic for a traditional six-speed manual remains.
But cosmetically, there will be very little to separate the two cars. Hennessey has crafted a new carbon fiber aero kit, comprising a much angrier front splitter, vented hood and fixed gooseneck rear wing. You’ll get 20in lightweight performance wheels and lots of Super Venom badging too. OK, so the latter is unlikely to contribute to better aero, but at least it looks cool.

The interior also gets a sweep, including leather and Alcantara-fied upholstery for the Recaro seats and a bespoke dashboard plaque with a build slot number. Yep, the Super Venom package will be limited. Very limited, actually, to just 91 units in commemoration of the American tuner’s founding year of 1991.
Pricing is set at $163,950 (approx. P9.5-M before taxes) for the Dark Horse and $149,950 (around P8.7-M before taxes) for the GT, which is respective of the cost difference between the standard Ford versions of the two models. So, one of these or a GTD?
