2006′s Shelby GT-H and later Shelby GT, based on the standard GT model, is modified by Carroll Shelby International to produce 319 hp (238 kW) by means of a Ford Racing air intake, performance tune, and upgraded exhaust system.
The Shelby GT-H, made available for rent only at selected Hertz car rental outlets, traces its roots to the original 1966 Shelby GT350H, famously known as the “Rent-A-Racer”. The GT-H appears only in black exterior paint and twin gold racing stripes as a nod to the Hertz company’s history. Completing the unique visual treatment is a billet aluminum grille, custom Shelby hood with functional hood pins, and the same front and rear fascia that would be found on the later Shelby GT and GT/CS models. The GT-H is outfitted with a Ford Racing Power Pack which includes a cold air intake, a revised exhaust system and custom performance calibration, boosting power to 319 hp (238 kW) and torque to 330 lb·ft (447 N·m). The GT-H also includes the Ford Racing Handling Pack with lowering springs, improved dampers, sway bars, a strut tower brace and a 3.55:1 ratio rear axle assembly.500 units of the coupe model were created for the 2006 model year, and a second run of 500 convertible models has been announced for 2008.
