第 12 集: 測試賽中，Speed 邂逅一輛與 Three Roses Club 昔日受害者有關的神秘車輛。
1967年6月18日 播出
During a test session Speed is overtaken by a mysterious car numbered X3, whose distinctive engine hum is familiar to a vicious gang of racers known as the Three Roses Club, because the engine is from a car whose driver they killed years earlier in a mountain race. When the mysterious driver turns out to be a robot who repeats a prerecorded warning, "Melange still races", it turns out to be the work of "Flash" Marker, the son of the deceased racer who has vowed to destroy the Three Roses Club at the same mountain course where his father was killed.
