This 71 cm tall set offers exciting action as a car races around the loop with the help of a booster. Add more cars (sold separately) for more action. Kids launch their cars into the loop while a booster keeps them in motion. The challenge is based on how many cars can race simultaneously before a collision occurs. The parking at the top of the loop holds up to 6 cars, keeping them close and ready for action. This playset connects with other Hot Wheels® sets (sold separately) so kids can make epic jumps and speed races.
