Think of the Ford Mustang Shelby GT500 kind of like a rolling theme park. Its monstrous 760-hp supercharged V-8 launches the coupe with eye-watering force, and its immense grip causes sensations of euphoria or nausea or both. All the while its thrilling exhaust note provides the soundtrack, and a rapid-shifting automatic transmission handles gearchanges for the rear-drive-only coupe.
