If you want to see some crazy excess, you'd head to Las Vegas, right? We'd say $80,000 for a Mustang is excessive. So, too, is 540 hp. Thus, it's only fitting that this particular Mustang is from Vegas. It may start its production process in Michigan as a "regular" GT500, but it's finished off at the Shelby factory in Sin City, where it becomes the King of the Road.
The new, extra-excess Shelby uses the 5.4-liter supercharged V-8 from the current GT500 but gains 40 hp and 30 lb-ft of torque through revised engine programming. The V-8 exhales through a new low-restriction exhaust that employs an H-pipe - in place of the GT500's X-pipe - to accentuate the V-8's burble; its lovely lope sounds like a big-bore boat engine at idle, and in normal driving, it sets off car alarms and sends pedestrians scurrying for cover. Boot the loud pedal, and the supercharger's psychotic whine conspires with the V-8's demonic wail to drown out even the loudest of police sirens. The regular GT500 sounds like a Toyota Prius by comparison.
