Ford introduced the Shelby GT-H version of the Mustang at the 2006 New York Auto Show. Like the original GT350H from 1966, the GT-H featured gold-on-black paint and was only available at the Hertz car rental agency. A modest power bump over the regular Mustang GT V-8 engine. Features included a 5-speed automatic transmission, and a package from Ford Racing including a 90 mm cold air intake kit, X-pipe, special performance suspension, and Ford Racing “GTA” axle-back mufflers. Only 500 cars were built to celebrate the 40th anniversary of the original Shelby GT350H. For 2007, a convertible version of the GT-H was offered for rental at Hertz.
The 4.6 liter, 281-cubic-inch, 319 hp (238 kW) Ford Shelby GT slots between the 300 hp (220 kW) Mustang GT and the Ford Shelby GT500. It is essentially a retail sale version of the Hertz rental-only Ford Shelby GT-H, except a manual transmission is available. Other differences include the deletion of the rear spoiler, a retro Shelby hood scoop in place of the CS6/8 Shelby hood, and silver versus the gold stripes, with the car available in either white or black in 2007 and Grabber Orange or Vista Blue for 2008. A very limited number (100) Barrett Jackson Shelby GTs were built in 2008 that were black with red stripes. The Hertz Shelby GT-H attracted so much attention that Ford dealers and customers asked for a version of their own. Like the GT-H, the Shelby GT is modified at Shelby Automotive’s factory in Las Vegas, which distinguishes the GT-H and Shelby GT models from the GT500 in that the GT500’s are produced entirely in Flat
