The Hot Wheels? Action Ultra Hots? Rev Rally track set delivers high-speed racing with the exciting anticipation of near-misses on a figure 8-shaped track. Kids crank the rev booster which sends cars into action; master the timing to get as many vehicles on the track at once before there’s a collision in the crash zone. The set comes with three Hot Wheels? cars to start racing immediately, and it folds in half for easy and convenient storage. Not for use with all Hot Wheels? vehicles. Colors and decorations may vary.
