Earlier today, Ford released details on the 2011 Shelby GT500 that will be arriving at the firm's U.S. dealerships by the end of Spring. Now, we've got two promotional films of the GT500 coupe and its convertible sibling showing off their goods that include a 5.4-liter supercharged V8 engine with massive amounts of torque and a thuggish burble. So yes, we'd advise you to turn up the volume once you hit the jump to watch both videos.
