Nearly the entire powertrain has been upgraded for 2013, including a new cross-drilled block and heads, updated camshaft profiles, a carbon fiber driveshaft and upgraded clutch, transmission and axle.
Aesthetically, not too much has changed outwardly on the Shelby, aside from some aerodynamic tweaks, new air splitters and slightly redesigned rear.
