Under the hood, the convertible features the same Ford Racing Power Upgrade Package as found in the coupe. Output of the 4.6L V8 is lifted to 319hp and 330lb.-ft. of torque thanks to a high-flow exhaust system with X-pipe crossovers. The Shelby GT comes standard with a five-speed manual transmission featuring a Hurst short-throw shifter, while a five-speed auto is available as an option.
Other features include 18in polished wheels with 235mm BF Goodrich tires, a Ford Racing Handling Pack with special-tuned dampers, unique sway bars and a 3.55:1 ratio rear axle assembly plus a lowered ride-height.
For the 2008 model year, developers have introduced a new color, Vista Blue with Silver stripes, available on both the coupe and convertible.
