Pure power is the brazenly visible trait defining the 2013-2014 Mustang Shelby GT500 trims, designed – much like the 1993 Cobra – to best a Chevy competitor, in this case the ZL1 Camaro with its 580 horses. At the core of both models is a 32-valve 5.8L supercharged V8 engine developing 662 horsepower and 631 ft-lbs of torque, EPA rated for 15/24 mpg city/highway. With this much engine power, the Mustang Shelby GT500's motion is more like a blastoff than mere acceleration, punching the muscle car from 0 to 60 mph in 3.5 seconds and conquering the quarter-mile in 11.81 seconds. The car's chassis and drivetrain elements are strongly modified and reinforced so that the Shelby doesn't rip itself apart with its own engine power. Some reinforcing features include a one-piece carbon fiber driveshaft, braces for the driveshaft tunnel, and tough, lightweight billet aluminum suspension components. The nominal top speed is 220 mph, though 212 mph is the fastest recorded speed on an Italian testing track. With no grille to block airflow, 2013 to 2014 Shelby GT500s sport Twin Vortices 2300 superchargers adding 14 psi. The Shelby's compression ratio of 9.0:1 is supported by a massive 93.5mm bore and 105.8mm stroke. Lest appearance and comfort be forgotten, the leather and alcantara interior features upholstery with inset racing stripes in black, blue, red, or white for additional swank. The 2013 Shelby's base MSRP is $54,995 for the coupe and $59,995 for the convertible, while the 2014 Shelby costs $55,110 (coupe) or $69,660 (convertible).
