Ford hit a home run with the 2013 Mustang Shelby GT500. New for the 2013 GT500 is a 5.8L aluminum-block with a more efficient supercharger. Nearly every aspect of the drive train was changed including cross-drilled block and heads, a carbon fiber drive shaft, updated cam profiles and much more. Ford claims 200 miles per hour has been achieved! That makes it the fastest mass produced V8 car ever!. All of this at just under $60,000 makes this Shelby a force to reckoned with.
