Called the Shelby 1000, two versions of the Mustang will be offered - a street legal 950bhp version running on standard fuel and an S/C track version rated at over 1100bhp.
The beefed-up 5.4-litre V8 gets a new supercharger and internals, including crank, plus flowed head, revised cooling and exhaust. To cope with the power, the Mustang also sports an uprated driveshaft and fully reworked suspension.
Including the donor Mustang GT500, the cost is estimated at the equivalent of £126k. Just 50 of the most powerful cars will be built.
