“KR” is for King of the Road, and there's 540 horsepower that won't let you forget that the Ford Shelby GT500KR is one of the most powerful Mustangs ever built. The boost comes from the Ford Racing Power Upgrade Pack, while other upgrades include a carbon composite hood, air extractor vents and 14-inch Brembo brakes. The production version will come with 18-inch chrome wheels, not the show floor model's 20-inch set. Ford is planning for a build of about 1,000 units, at a price of $50,000.
