Speed has announced that during this year's 39-hour live coverage of the Barrett-Jackson automobile auction in Scottsdale one lucky punter will drive away with a 2013 Ford Shelby GT500 Mustang HFB Special Edition. To stand a chance of winning the custom GT500, simply take part in Speed's Hagerty Fantasy Bid and you'll automatically become eligible for the grand prize. Speed says that the winner will be drawn from all the fantasy bid entries on Sunday, 20 January.

The one-off Shelby comes fully loaded with performance goodies, from a Ford Racing lowering kit, Hyrdraulic Hood struts and Borla exhaust system to full-length stainless-steel headers, high-flow air filter and an Ice Nine modified air intake. There's no official word on final output, but Speed claims the HFB edition can churn out over 800 horsepower. In terms of looks, an all-black exterior married to a W2 Graphics flat black stripe kit is complemented by a set of 20-inch aftermarket alloys fitted with Drag Radial tires, while other exterior mods include a custom billet antenna, carbon fender scoops, and aluminum Hagerty Fantasy Bid badging.
