第 10 集: Speed 在危險的競賽中面臨致命的山彎與險峻裂谷
1967年6月4日 播出
Forced to finish preparing the Mach 5 himself, Speed barely reaches the race's start, but Sparky and Trixie must rescue him when his brakes prove ineffective in a lethal mountainside curve, and after he rejoins the race, he and others run into brutal rains that wash out overhangs, forcing them to have to jump the dangerous chasms. Snake Oiler and Racer X succeed, but when Speed makes the jumps, his car crashes into a canyon and amid the wreckage and loss of life, the only sign of Speed in the fatal storm is a small doll given him by his younger brother, Spritle.
