Shelby American is celebrating the 50th anniversary of Shelby automobiles, and the specialty maker, which builds performance cars from Ford Mustangs, showed three golden anniversary editions at the 2012 North American International Auto Show in Detroit. Each will be built in two paint colors with gold stripes. The “top of the line” GT500 Super Snake will develop 750 hp (560 kW). For the buyer who wants more, there is an optional state of tune rated at 800 hp (588 kW), delivered with the boost from a polished Shelby/Kenne Bell 3.6-L liquid-cooled supercharger.
The GT500 Super Snake first appeared in 2007. The 750-hp edition is equipped with the Shelby/Ford racing supercharger. Either GT500 comes with many carbon fiber body parts, Shelby six-piston caliper front brakes, Borla cat-back exhaust system, Shelby/Ford racing suspension with adjustable dampers, ball billet short-throw shifter, a one-piece aluminum propeller shaft, 20-in aluminum wheels, and signature trim pieces and labels.
Just 50 of each 50th anniversary model will be produced for a total of 300 vehicles. A buyer may choose the coupe or a convertible. All three Shelby vehicles run on pump gasoline (91 research octane).
The GT350 is a “lower performance” choice but can be supercharged to 525 hp (386 kW) or 624 hp (459 kW). This model, based on the 2012 Mustang GT with the 5.0-L V8, is rated at 430 hp (320 kw) naturally aspirated vs. 412 hp (307 kW) for the OE version. The GT350 package adds a Whipple supercharger to raise performance to 525 hp (386 kW). An optional second Whipple supercharging choice can raise output to 624 hp (459 kW). Either is capable of a 0-60 mph (0-98 km/h) time of 3.7 s. Among the package components are racing suspension with caster-camber adjustment kit and Goodyear performance tires.
There is also the edition called “a first Shelby,” the entry-level Shelby GTS, which is available in an EPA 30 mpg highway version with a Ford 3.7-L six-cylinder engine, OE-rated at 305 hp (228 kW). This engine can be supercharged to 475 hp (349 kW) as an optional upgrade. Other options include front and rear brake upgrades, a Watts link rear suspension, special wheels and tires, and a Shelby-Eibach suspension kit. If the buyer chooses a Mustang GT V8, he also can select the Shelby GTS approach. It is lower in initial cost because it permits an a la carte approach to upgrades, including the 525- and 624-hp superchargers, as well as the chassis options available with the V6 model.
