Shattering the speed of sound!
Those sonic booms you hear mean the Zonic Stike is on its way! This Racer is so fast it has to compete underground, or windows would shatter as it breaks the sound barrier. Watch it tear through the tunnels on its way to another victory! A crack crew of mechanics can rebuild it into a desert Road Runner or a Formula racer.
