to the upcoming Grand Prix. The Racer family bands together and builds a new Mach 6 in 32 hours. Speed enters the Grand Prix with the help of Inspector Detector against great odds; Royalton has placed a $1,000,000 bounty on his head that the other drivers are eager to collect, and he is pitted against future Hall of Fame driver Jack "Cannonball" Taylor. Speed overcomes a slow start to catch up with Taylor, who uses a cheating device called a spearhook to latch the Mach 6 to his own car. Speed uses his jump jacks to expose the device to video cameras, causing Taylor to crash. Speed wins the race, having successfully exposed Royalton's crimes. While Racer X watches, a flashback montage reveals that he really is Rex, having faked his death and undergone plastic surgery to change his appearance as part of his plan to protect Speed and the sport of racing. He chooses not to reveal his identity to his family, declaring that he must live with his decision.
