A:Answer Under Features I found this...
The motorized action of the Hot Wheels City Roller Coaster Rally Track Set makes for non-stop adventure that takes the Hot Wheels experience to the extreme!
It comes with 5 Hot Wheels vehicles and all 5 can run at once thanks to the track set's size and booster.
Kids control the diverter that determines the route cars take on the downhill, upping the challenge with each additional vehicle added to the set.
It connects to other Hot Wheels City sets to inspire creative stories and awesome adventures.
This makes a great gift for kids 4 to 8 years old, and, with 5 included Hot Wheels cars, the fun is instantaneous.
