This is the slot car set that unfolds from its carrying case to form an instant, two-laned raceway for two Hot Wheels slot cars. When opened the case forms an oval course with more than 5 1/2' of track that’s ideal for beginning slot car drivers. The two 1:64 scale race cars have responsive contact brushes and road-hugging rubber tires that help them zip through turns without jumping the track. Includes two wired controllers, built-in lap counters, and accessories for decorating the racecourse. For indoor or outdoor play. Requires 5 AA batteries. Ages 5 and up. Deployed 37 1/2" L x 15 1/2" W x 2 1/4" H; closed 19" H x 15 1/2" W x 4 1/2" D. (4 lbs.)
