The Hot Wheels Action Spiral Speed Crash Track Set delivers big-time thrills with a 29-inch-tall track, three crash zones and a motorized booster that keeps the car moving. Drive the included Hot Wheels vehicle up to the booster and watch it continuously whip down the spiral. To increase the challenge, add additional cars until there's an inevitable wipe-out in one of the crash zones. Store up to 6 cars atop the battery box and booster. Additional cars sold separately. Colors and decorations may vary.
