One of the more popular stunts at Disney's MGM Studios is the "Ballet Chase," which pits a bunch of tiny bad guys in black hatchbacks against a protagonist in a custom-bodied red sports car. How, exactly, does one get this Disney summer internship?
IIRC, this show was originally called "Lights! Motors! Action!" The cars are pretty heavily modified (I think the main stunt car is custom-built), while the black chase cars are based on Opels. They have tiny fuel cells (only enough for one performance), special gearboxes which allow them to drive backwards equally well, drift-style handbrakes and cool-suits for the drivers (the mid-summer Florida heat can be a bitch.) I think the main stunt car's engine is from either a motorcycle or a snowmobile and is mid-mounted so the car will land correctly on the jumps.
There are all kinds of interesting factoids about the show (such as the tiny built-in water cannons in the arena floor to simulate bullet hits.)
Modern Marvels did an episode which showcased a lot of the tech behind Disney World and this one of the shows they featured.
