Specially shipped to West Sussex for its first appearance outside America, the supercar, which is only on sale in the USA, will be driven up the hill by guest race drivers during Lord March's weekend-long extravaganza.
The car's appearance honours Shelby, who died earlier this year. the automotive designer and former racer who was responsible for developing some of the Blue Oval's most powerful Mustang-based performance cars.
The latest Ford Shelby GT500 is powered by an aluminium 5.8-litre supercharged V8 engine, producing 653bhp and 631lb ft of torque. The most powerful engine ever in a North American production car, it propels the Shelby GT500 to a top speed of more than 200mph.
The Shelby GT500 has updated gearing to enhance the way it lays down its power, tuned suspension and an adjustable launch control system.
